THERMAL REACTOR MOVABLE SHROUD

A movable thermal shroud includes a mounting body with a framed opening, and a plurality of slats, each movably mounted to the mounting body in a stacked configuration and each slat extending across the length of the framed opening. An operation mechanism is configured to position the slats in the closed configuration or in the open configuration. A method for monitoring an inner equipment system includes placing a movable thermal shroud around the inner equipment system and moving the plurality of slats to the closed configuration using the operation mechanism to enclose the inner equipment system and moving the plurality of slats to the open configuration using the operation mechanism to access a portion of the inner equipment system.

BACKGROUND

Thermal reactors are commonly designed with an external thermal shroud (sometimes referred to as a rain shield) mounted around the outer shell of the thermal reactor. Shrouds may be designed and fitted around the thermal reactor shell to maintain air flow between the shroud and the thermal reactor shell. Such air flow path may help to maintain a layer of warm air that may protect the shell from thermal shock due to significant changes in the surrounding environmental temperature. Additionally, shrouds are used to protect the thermal reactor shell from environmental conditions such as solar radiation, wind, and rain, that can significantly affect the shell temperature or cause the shell temperature to move out of an allowed temperature range for the thermal reactor shell. For example, when a thermal reactor has a carbon steel shell, high temperatures of about 650° F. may cause sulfidation corrosion of the shell and low temperatures below the acid dewpoint (e.g., less than about 350° F.) may cause acid corrosion.

FIGS.1A and1Bdemonstrate conventional thermal shroud design and function used with a system100including an external thermal shroud102protecting a thermal reactor104having a combustion chamber112enclosed by a refractory lining and a shell106, where the shell106forms an outer surface of the thermal reactor104. Conventionally, thermal reactors104are designed with a static external thermal shroud102, as shown inFIGS.1A and1B, to protect the shell106from solar radiation, wind, and rain which can significantly affect the shell's106outer temperature.

FIG.1Bshows a functional schematic of the thermal shroud design according to prior art, where the thermal shroud102allows air flow from an ambient air inlet114, around the outside of the thermal reactor104. Hot air exits the thermal shroud102at an outlet116. The space between the inner equipment and the shroud102allowing air flow from the inlet114to the outlet116may form a warm air flow blanket around the thermal reactor104, helping to maintain the shell106metal temperature and also protect the shell106from thermal shock, which may occur from rain or cold winter conditions, for example.

While conventional shroud design may provide a warm air flow blanket formed between the inner equipment and shroud, such as shown inFIG.1B, conventional shroud design does not provide access to the shell (or other outer surfaces) of thermal reactors such that the shell can be inspected fully during operation and equipment turnaround without physically dismantling and removing the shroud. To accommodate for such limited access to the thermal reactor, some systems have included many thermocouples installed externally around the thermal reactor to measure the temperature. However, in these systems, complete shell monitoring around the thermal reactor is still not possible. Thus, the limited access to conventional thermal reactor systems can lead to undetected hot or cold spots along the thermal reactor shell, which can cause damage to the shell.

The movable thermal shroud includes a plurality of slats, each having a first end and a second end opposite the first end, where the plurality of slats are movably mounted to the mounting body at the first end and at the second end and are movable relative to the mounting body between a closed configuration and an open configuration. The plurality of slats are mounted to the mounting body in a stacked configuration along the height of the framed opening and each of the plurality of slats extend across the length of the framed opening.

DETAILED DESCRIPTION

It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a fluid sample” includes reference to one or more of such samples.

Embodiments disclosed herein generally relate to movable thermal shrouds and systems and methods of their use. Movable thermal shrouds disclosed herein may include a plurality of slats that are movable relative to a mounting body. The slats may be connected to the mounting body in such a manner that the slats may be moved between an open configuration and a closed configuration while the mounting body remains in a fixed position.

Movable thermal shrouds according to embodiments of the present disclosure may provide a resolution to current field challenges of inspecting and maintaining a thermal reactor or furnace. For example, a movable thermal shroud according to embodiments of the present disclosure may be positioned around a thermal reactor, where the mounting body of the movable thermal shroud may remain in a fixed position relative to the thermal reactor while the slats are moved relative to the mounting body (and thermal reactor) between their open and closed configurations. In such manner, the movable thermal shroud may permit visibility and accessibility to the thermal reactor external shell during normal operation, routine thermal infrared scanning (refractory monitoring), and startup and shutdown inspection without dismantling the shroud.

Measuring the shell outside temperature (for example, continuous online temperature measurement) of thermal reactors and other process equipment is done to ensure safety and to avoid equipment failure during normal operation and start-up and shutdown. For example, continuous monitoring of process equipment external shell temperature may be a safety requirement to ensure no hot or cold spots and no toxic gases (e.g., H2S) are released during operation. The consequences of undetected failures in the reactor shell in a timely manner during operation can be very serious in terms of personnel safety, assets integrity and can lead to costly unplanned shutdown. Sudden equipment failure due to high temperature occurs in the field and results in safety risk, operation disruption, and financial losses.

For example, in two case studies of failed thermal reactors, where hotspots were not detected during operation, the thermal shroud was one of the causal factors contributing to the failure in both incidents because the thermal shrouds covered the thermal reactor shells and prevented inner equipment visibility. In the first case study, a thermal oxidizer sulfur recovery unit (SRU) experienced a hot spot in its outer shell during startup, which led to damage and a shell opening. The hot spot was not detected until the entire outer shell was glowing red around the sides of the fixed shroud and damage was apparent. In the second case study, another thermal reactor experienced an emergency shutdown due to an open flame at the top section of the thermal reactor, which was caused by high flame temperature in the thermal reactor during the reactor startup. The open flame was not observed because a conventional thermal shroud was covering the thermal reactor's shell, and two internal refractory layers and the carbon steel external shell of the thermal reactor were completely melted. In both case studies, the equipment external shells were damaged and melted where the thermal shroud acted as an obstacle to the operator's visibility.

While conventional shroud design typically requires shroud removal or disassembly for conducting inspection activities, movable thermal shrouds disclosed herein will allow operators and inspectors to have easy access to the inner equipment's external shell (or other outer surfaces) to conduct inspection activities. Inspection activities may include, for example, thermography, routine thermal scan (refractory integrity monitoring) inspection, visual inspection, and verifying the cause of a temperature change. Inspection activities may also include remediation, to make appropriate actions before reaching a temperature limit that damages the surface and causes a dangerous field condition. The ability to fully inspect and monitor the external shell of a thermal reactor or other high temperature equipment system may occur during normal operation and critical operation scenarios (startup and shutdown). Movable thermal shroud design according to embodiments of the present disclosure allows inspection and monitoring without having to shut down the operation process, thereby reducing maintenance time with no need for removals and re-installation. Additionally, movable thermal shrouds according to embodiments of the present disclosure can be opened and closed easily without affecting the shroud performance, which may also enhance the equipment integrity and refractory monitoring.

One or more embodiments relate to a movable thermal shroud apparatus. The movable thermal shroud may include at least a mounting body, a plurality of slats, and an operation mechanism. When positioned around an inner equipment system (e.g., a thermal reactor or other high temperature equipment), a movable thermal shroud according to embodiments of the present disclosure may enclose or entirely surround a section of an outer shell of the inner equipment system. One or more embodiments also relates to a method for monitoring an inner equipment system using a movable thermal shroud.

A movable thermal shroud of one or more embodiments may be positioned in an open or closed configuration, such that the inner equipment system is accessible when in the open position. The movable nature of movable thermal shrouds disclosed herein may provide the advantage of more readily providing visibility and accessibility to the inner equipment system as compared to conventional static thermal shrouds because conventional static thermal shrouds typically do not provide access to the inner equipment system without physically dismantling and removing the shroud. The ability to readily access the inner equipment system using the movable thermal shroud of one or more embodiments (e.g., by merely opening/closing slats of the movable thermal shroud) may provide the advantage of ease of monitoring and inspection, and prevention of damage to the inner equipment system during operation.

FIGS.2A-2Cshow a generic movable thermal shroud system and mechanism of operation according to one or more embodiments disclosed herein. The system200ofFIG.2Aincludes a movable thermal shroud202which encloses a section of an outer surface212of an inner equipment system210and an infrared (IR) camera214located outside of the system200which monitors the temperature of the inner equipment system210. In one or more embodiments, the enclosed section of the inner equipment system210may include a thermal reactor. In the embodiment shown, the movable thermal shroud202extends in a first dimension around a height201of the inner equipment system210and in a second dimension along a length203of the inner equipment system210to surround the section of the inner equipment system having the height201and length203. The size and shape of the movable thermal shroud202may be designed to entirely surround the selected section of the inner equipment system while also allowing a space between the outer surface212of the inner equipment system210and the movable thermal shroud202. In one or more embodiments, the space between the inner equipment system210and the movable thermal shroud202may have a substantially uniform radial distance around the entire enclosed section of the inner equipment system210. Such space may allow thermally protective airflow between the inner equipment system210and the movable thermal shroud202.

One or more legs205, brackets, or other assembly equipment may be used for assembly of the movable thermal shroud202around the inner equipment system210. In some embodiments, a movable thermal shroud202may sit on the ground and may extend upwardly from the ground and around a section of an inner equipment system to enclose the section of the inner equipment system (e.g., as shown inFIG.5).

Keeping withFIGS.2A-C, the movable thermal shroud202includes a mounting body204, a plurality of slats206movably mounted to the mounting body204, and an operation mechanism208. In the embodiment shown, the mounting body204contains a framed opening having an area defined between a frame height228and a frame length226, where the plurality of slats206extend in a parallel configuration across the framed opening. The slats206are movably mounted to the mounting body204, operable between a closed configuration and an open configuration, as will be described in more detail inFIGS.2B and2C. The operation mechanism208is configured to position the plurality of slats206in the closed configuration or in the open configuration. For example, in one or more embodiments, the operation mechanism208may include a line (e.g., string or wire) connected to an end of each of the slats206and a pully (not shown) positioned internally in the mounting body204. An operation mechanism handle positioned along an exterior of the mounting body (e.g., in an accessible location) may be connected to the pully, such that rotation of the operation mechanism handle may rotate the pully, thereby moving the line around the pully. In one or more embodiments, the line may be connected at the end of the slats, proximate a same lateral side of the slat ends, such that movement of the line by the pully moves the connected lateral side of the slats in an open or closed direction relative to the opposite lateral side of the connected end.

FIGS.2B and2Cshow a portion of the movable thermal shroud202, where the plurality of slats206in a closed configuration220and in an open configuration240, respectfully. InFIG.2B, the plurality of slats206are in the closed configuration220, enclosing a selected section of an inner equipment system210. The plurality of slats206each have a slat length225measured between opposite axial sides at a first end222and a second end224opposite the first end222, and a slat height227measured between opposite lateral sides. In the embodiment shown inFIGS.2B-C, the plurality of slats206are movably mounted to the mounting body204at the first end222and at the second end224, such that the slat length225extends across the frame length226of the mounting body204and are movable relative to the mounting body204between a closed configuration220and an open configuration240. Additionally, the slats206may be mounted to the mounting body204in a stacked configuration relative to each other along the frame height228of the framed opening, such that the opposite lateral sides of each slat206are parallel with and next to each other. When the slats206are in the closed configuration220, the lateral sides of each slat206may be adjacent to (e.g., in contact with, or with a maximum space therebetween that allows relative movement of the slats) or overlapping with neighboring slats206. In one or more embodiments, the maximum space between adjacent lateral sides when the slats are in a closed configuration may be minimized to maximize protection of the inner equipment system from solar radiation, rain, winds, etc. Therefore, when the plurality of slats206are in the closed configuration220ofFIG.2B, the area of the framed opening is substantially or entirely covered by the slats, and thus also the outer surface212of the enclosed inner equipment system section is substantially or entirely covered by the slats. The closed configuration220ofFIG.2Brepresents the positioning of the plurality of slats206of the movable thermal shroud202during normal operation, for example.

InFIG.2C, the plurality of slats206are in the open configuration240, exposing a portion of the inner equipment system210. In one or more embodiments, at least 80% of the area of the framed opening (e.g., 80-99%) may be open when the slats206are in the open configuration240. The exposed area of the framed opening may provide visibility to the outer surface212of the inner equipment system, as defined by an exposed area242measured between the open slats206from a radially outer perspective. Moving the plurality of slats206into the open configuration240and exposing a portion of the framed opening renders the inner equipment system210accessible. The open configuration240ofFIG.2Crepresents the positioning of the plurality of slats206of the movable thermal shroud202during monitoring or maintenance, for example.

In some embodiments, the slats206may be opened by moving to a perpendicular position relative to their closed configuration, where in the closed configuration, the slat height227extends in an initial direction, and in the open configuration, the slat height227extends in a perpendicular direction to the initial direction. By moving the slats to rotate their slat height direction about 90 degrees between the open and closed configurations, a relatively larger exposed area of the framed opening may be provided to improve visibility through the movable thermal shroud202.

FIGS.2B-Cshow a planar portion of a movable thermal shroud202. However, in one or more embodiments, the movable thermal shroud202may have a non-planar mounting body204. When slats206are mounted along a planar portion of a mounting body204(extending along a first plane), the slats may be substantially co-planar with the planar portion of the mounting body204when the slats206are in the closed configuration220, and the slats206may extend in a substantially perpendicular direction (perpendicular to the first plane) to the planar portion of the mounting body204when the slats206are in the open configuration240. In some embodiments, slats206are mounted along a curved, angled, or other non-planar portion of a mounting body extending in a first dimension (e.g., height dimension) and a second dimension (e.g., length dimension) perpendicular to the first dimension. In such embodiments, the slats206may be mounted to the mounting body such that the slat length of each slat extends parallel with the mounting body frame length, along the second dimension. Additionally, when mounted along a non-planar portion of the mounting body, the slats206may move between the open and closed configurations, where the axial sides of each slat are substantially aligned with the mounting body along the first dimension when in the closed configuration, and where the axial sides of each slat may extend perpendicularly from both the first and second dimensions when in the open configuration.

In one or more embodiments, at least one sensor may be positioned on the outer surface212of the inner equipment system210. The sensor or sensors may be configured to measure one or more environmental parameters, for example, the environmental parameter may be selected from the group consisting of temperature, humidity, wind speed, pressure, and toxic gas level. The sensor may also be configured to detect a position of the slats206, such as if the slats are in the open configuration or in the closed configuration. In some embodiments, one or more first sensors measuring a first environmental parameter may be positioned upon the outer surface212of the inner equipment system210, and one or more second sensors measuring a second environmental parameter may be positioned upon the outer surface212of the inner equipment system210.

The movable thermal shroud of one or more embodiments may provide protection to an inner equipment system during normal operation. The movable thermal shroud may be used either indoors or outdoors in industrial facilities such as petrochemical plants, refineries, gas plants, and the like, or any other suitable facility or application. The movable thermal shroud may provide protection from weather conditions such as solar radiation, wind, rain, temperature changes, dust, dirt, or other natural or man-made conditions created indoors or outdoors.

The inner equipment system may be any inner equipment system known in the art. For example, the inner equipment system may be a tank, a reactor, a thermal reactor, a nuclear reactor, a thermal oxidizer, a furnace, a pressure vessel, and the like.

In one or more embodiments, the outer surface of the inner equipment system may be a shell, casing, or any other protective layer known in the art.

In one or more embodiments, the mounting body may be any shape or mechanical construction capable of having a plurality of slats movably mounted to the mounting body. The shape of the mounting body may be, for example, a cubic or other polygonal cage or may be cylindrical, semi-cylindrical, or domed. The mounting body may be further define a framed opening having an area defined by a height and a length, e.g., a planar polygonal area (e.g., a rectangular area), a curved polygonal area (e.g., a convex rectangular area), or other curved or planar area. A plurality of slats may be movably mounted in parallel with a dimension (e.g., the length) of the mounting body.

In one or more embodiments, the plurality of slats may be constructed in any size, shape, or geometry to allow the plurality of slats to be movably mounted to the mounting body and operable in an open configuration and a closed configuration. For example, the plurality of slats may have a slat length in a range of from about 1000 mm to about 2000 mm, a slat height in a range of from about 50 mm to about 250 mm, and a slat thickness in a range of from about 1 mm to about 2.5 mm.

In one or more embodiments, the plurality of slats may be made of any suitable material known in the art. The material may be metallic or non-metallic. Examples of slat materials may include, but are not limited to, stainless steel, aluminum, carbon steel, or non-metallic composites.

The operation mechanism of one or more embodiments may be different types of operation mechanisms that are capable of moving connected slats between an open and closed configuration. For example, the operation mechanism may be a line and pulley-type operation mechanism, a handle or lever, a pull string, a mechanical button, a crank, wheel, or any other suitable operation mechanism.

The operation mechanism of one or more embodiments may be provided in different locations along the movable thermal shroud which allows for ease of access and for the operation mechanism to open/close the slats of the movable thermal shroud. In some embodiments, the operation mechanism may be manually or mechanically operated. In some embodiments, the operation mechanism may be automatically operated (e.g., upon receiving signal(s) from a computer system).

The IR camera (e.g., IR camera214) of one or more embodiments may be any suitable temperature monitoring tool known in the art. The IR camera may be used to monitor the temperature of the outer surface of the inner equipment system by measuring the shell temperature and to check refractory integrity. Having the movable shroud design in an open configuration provides accessibility and exposure of the inner equipment system to the IR camera, thereby providing access to the inner equipment system for online monitoring through the IR camera. In one or more embodiments, having the movable shroud in an open configuration allows for accessibility and monitoring of the inner equipment system using other techniques such as visual inspection, in addition to other measurements and inspection during equipment turnaround (thickness measurement and shell inspection) without the needs for the shroud dismantle. In addition, having movable thermal shroud may allow for optimization of the refractory thickness design in an inner equipment system.

FIGS.3A-3Cshow examples of multi-louver movable thermal shroud designs according to one or more embodiments disclosed herein.FIG.3Ashows one example of a multi-louver movable thermal shroud design according to one or more embodiments. InFIG.3A, the mounting body204includes a first side302and a second side304of a framed opening. InFIG.3A, an internal view of the first side302is shown to demonstrate an example of an operation mechanism308that may be used to move a plurality of connected slats between an open and closed configuration within the framed opening. Each of the plurality of slats206are movably connected with the first end222to the first side302of the mounting body204and the second end224to the second side304of the mounting body204. In the example embodiment shown, the operation mechanism308includes a connecting rod that is slidably mounted in the first side302of the mounting body. The connecting rod may be connected (e.g., welded) proximate to a same lateral side of the slats206at the first end222of the slats. The opposite lateral sides of adjacent slats206may be connected via a clip member, and a first slat may be connected to a top side303of the mounting body. Such assembly may allow for the same lateral side of the slats (connected to the connecting rod) to be moved relative to the opposite lateral sides of the slats, thereby moving the slats between the open and closed configurations. In one or more embodiments, the connecting rod may have an operation mechanism handle extending external to the mounting body, such that the operation mechanism handle is accessible for moving the connecting rod.

FIG.3Bshows another example of a multi-louver movable thermal shroud design according to one or more embodiments. InFIG.3B, the mounting body204includes a plurality of clip members322connected at a hinged connection to the mounting body204and connected to a same lateral side of the slats206at the first end222of the slats. For example, each of the plurality of slats206may be connected at least at the first end222by seating or clipping the same lateral side in each of the plurality of clip members322of the mounting body204. In such assembly, each clip member322may extend from the hinged connection at the mounting body204to a same lateral side of each slat206. An operation mechanism309including a connecting rod may be connected to each of the clip members322proximate the same lateral side of the slats206. Axial movement of the connecting rod correspondingly moves the same lateral side of the slats206relative to a fixed location hinged connection at the mounting body, thereby positioning the plurality of slats206in the closed configuration or in the open configuration.

Examples of operation mechanisms utilizing a connecting rod are shown inFIGS.3A and3B; however, other configurations of operation mechanisms may be used to move a plurality of slats in an open and closed configuration. For example, an operation mechanism may include interlocking gears or a pully assembly connected directly or indirectly to all of the clip members, where movement of the operation mechanism (e.g., manual movement by a user or movement initiated by a signal from a computer system) moves all of the connected clip members to rotate downward (thereby moving the mounted slats to a closed configuration) or to rotate upward (thereby moving the mounted slats to an open configuration).

FIG.3Cshows another example of a multi-louver movable thermal shroud design according to one or more embodiments. InFIG.3C, the mounting body204includes a mounting frame342. Each of the plurality of slats206are movably connected in parallel to the mounting frame342. In the movable thermal shroud design ofFIG.3C, the operation mechanism may include a lever or handle307which is operatively connected to at least the first end222of the plurality of slats206and is configured to position the plurality of slats in the open configuration and the closed configuration. For example, in one or more embodiments, the first end222of the slats206may each be connected to a first side of the mounting frame342at a slat pivot point (e.g., at a midpoint along the first end of the slat), and the handle307may be operatively connected (e.g., via an attached wire or connecting rod) to the first end222of each slat206at a point along the first end spaced from the slat pivot point. In such embodiments, when the handle307is moved in a first direction, the connected points of the slat first ends222each move in the first direction with the movement of the connected handle307, thereby pivoting each slat in the first direction about the slat pivot point.

As described with respect to the thermal shroud system and mechanism of operation inFIGS.2A-2C, the multi-louver movable thermal shroud designs300,320,340according toFIGS.3A-3Cmay also enclose a section of an outer surface212of an inner equipment system210, extending in a first dimension around a height201of the inner equipment system210and in a second dimension along a length203of the inner equipment system210. The multi-louver movable thermal shroud designs according toFIGS.3A-3Calso includes a framed opening defined by an area of the mounting body204having a frame height228and a frame length226. The plurality of slats206may be mounted in a stacked configuration relative to each other along the frame height228, extending across the length226of the framed opening. The multi-louver moveable thermal shroud designs ofFIGS.3A-3Callow for at least 80% exposure of the area of the framed opening (e.g., 80-99%) when the plurality of slats206are in the open configuration240.

FIGS.4A-Bshow an example of a rolling or folding movable thermal shroud design according to one or more embodiments. InFIGS.4A-B, the movable thermal shroud400includes a mounting body having an elongated member402, which is used to open and close a plurality of slats404. As shown inFIG.4B, an IR camera214may be located outside of the system200which monitors the temperature of the inner equipment system411. In some embodiments, the elongated member402may be a cylindrical rod. The elongated member402may be rotatably mounted to a frame405of the mounting body, where the elongated member402is rotatable about a rotational axis401. For example, an elongated member may be rotatable via an operation mechanism including a motor and/or gear assembly provided with the mounting body. In some embodiments, the operation mechanism may include a different torquing or rotational motor assembly. In some embodiments, the operation mechanism may be a handle that is rotated to manually rotate the elongated member relative to the remaining mounting body frame.

The movable thermal shroud400also includes a plurality of slats404connected to the elongated member402via a first slat403. For example, the first slat403may be welded, tied, or otherwise connected to the elongated member402to hold the first slat403parallel with the elongated member402, such that the first slat403extends across a length412of the elongated member402. Each of the slats404have a first end416and a second end418opposite the first end416and opposite lateral sides408extending between the first end416and the second end418. In some embodiments, the plurality of slats404may be formed of a large sheet (such as a corrugated sheet) having channels406dividing the slats404. The channels406may be lines of weakened or bendable portions of the sheet, such as linear grooves or perforated lines. In some embodiments, the slats404are connected together at opposite lateral sides408in a side-by-side configuration. For example, wire may be strung through the slat height of each slat to string the slats on the wire in the side-by-side configuration.

The channels406allow the sheet of slats404to roll around the elongated member402as the elongated member402is rotated about its rotational axis401, where each channel406may act as a linear bend point as the sheet of slats404is rolled around the elongated member402. Elongated members may have different sizes depending on the size of the mounting body, the size of the inner equipment system, and the size/amount of slats to be rotated around the elongated member. For example, an elongated member may have a diameter ranging from about 10 to 100 mm. When the elongated member402is rotated to a closed configuration, the plurality of slats404hang from the elongated member402and enclose at least a section of an inner equipment system411. When the elongated member402is rotated to an open configuration, at least a portion of the plurality of slats404are wrapped around the elongated member402and a portion of the inner equipment system411is accessible. The movable thermal shroud400ofFIG.4also includes an operation mechanism410configured to rotate the elongated member402between the closed configuration and the open configuration. In some embodiments, the operation mechanism may be manually operated. In some embodiments, the operation mechanism may be automatically operated.

The rolling or folding moveable thermal shroud design400according toFIGS.4A-Bmay enclose a section of an inner equipment system411, extending in a first dimension around a height413of the inner equipment system411and in a second dimension along a length415of the inner equipment system411. The rolling or folding movable thermal shroud design400according toFIGS.4A-Bcontains a framed opening having a maximum area defined by a length412of the elongated member402and a height414at which the elongated member402is rotatably mounted along the mounting body frame. The rolling or folding movable thermal shroud design400according toFIG.4allows for at least 80% exposure of the maximum area described above (e.g., 80-99%) when the plurality of slats404are in the open configuration (for example, when rolled or folded onto the cylindrical member402). In some embodiments, the rolling or folding moveable thermal shroud design400according toFIGS.4A-Ballows for 100% exposure of the maximum area described above when the plurality of slats404are in the open configuration (for example, when the slats are entirely rolled or folded onto the cylindrical member402).

In one or more embodiments, the mounting body of the rolling or folding movable thermal shroud design may be any shape or mechanical construction capable of having a plurality of slats movably mounted to the mounting body. For example, the mounting body may have a frame with a cylindrical shape, where the slats may be moved around cylindrical side of the frame. In some embodiments, such as shown inFIG.4B, the mounting body frame405may have a rectangular framed opening extending greater than the height413of an inner equipment system411, where the elongated member402may be rotatably mounted at the top of the framed opening. In such configuration, the sheet of slats404may be raised (opened) and lowered (closed) by rotation of the elongated member402to expose and enclose, respectively, the inner equipment system411.

The size of the mounting body may vary based on the size of the inner equipment system. For example, the mounting body frame405inFIG.4Bmay have a framed opening with a length412extending between 80-100% of the length415of a portion of the inner equipment system containing a high temperature equipment unit (e.g., a thermal reactor) and a height413extending between greater than 100% to about 110% of the portion of the inner equipment system being enclosed. For example, a framed opening may have a length412and/or height413ranging from about 700 mm to about 3,000 mm.

In one or more embodiments, the plurality of slats of the rolling or folding movable thermal shroud design may be any shape or mechanical construction capable of being movably mounted to the mounting body. For example, the plurality of slats may be sectional with larges pieces or a single continuous sheet. The large pieces may include section panels connected together in a corrugated channel and sheet configuration, or any other method known in the art.

In some embodiments, rather than orienting slats in a horizontal configuration (e.g., where the slat length extends along a length dimension of the inner equipment system), the slats may be oriented in a vertical configuration. In a vertical configuration, the slats may operate in the same manner as described herein with respect to the horizontal configurations but are oriented in a different direction. For example, in one or more embodiments, a mounting body may have a framed opening extending a height above an inner equipment system and a length along the length of the inner equipment system, where a plurality of slats may be movably mounted along the framed opening in a vertical configuration having the slat lengths extend along the height dimension of the framed opening. In such embodiments, the slats may be moved laterally (in a direction along the length dimension) between an open and closed configuration.

In one or more embodiments, the plurality of slats may be metallic or non-metallic, and may be made of any suitable material known in the art, as described above.

FIG.5shows a method for monitoring an inner equipment system using any of the movable thermal shroud designs of one or more embodiments. InFIG.5, a movable thermal shroud502is placed around an inner equipment system510and an IR camera214is located outside of the system500which monitors the temperature of the inner equipment system510. The movable thermal shroud502includes a plurality of slats506movably mounted to a mounting body504and operated in an open configuration or a closed configuration using an operation mechanism508. The movable thermal shroud502may be configured according to any of the movable thermal shrouds as described in previous sections. The method for monitoring an inner equipment system510includes moving the plurality of slats506to a closed configuration using the operation mechanism508to enclose a section of an outer surface512of the inner equipment system510, for example, during normal operation. The inner equipment system510may then be made accessible by moving the plurality of slats506to an open configuration using the operation mechanism508to expose at least a portion of the enclosed section of the inner equipment system510for monitoring and maintenance, for example.

In some embodiments, the method for monitoring the inner equipment system510using the movable thermal shroud502ofFIG.5also includes using at least one sensor502mounted to an outer surface512of the inner equipment system510. The at least one sensor502may be configured to monitor an environmental parameter. In one or more embodiments, the environmental parameter is selected from the group consisting of temperature, humidity, wind speed, pressure, and toxic gas level. The at least one sensor may include a position sensor configured to detect a position of the plurality of slats506, such as if the plurality of slats are in the open configuration or in the closed configuration. In some embodiments, a first plurality of sensors measuring a first environmental parameter may be positioned upon the outer surface512of the inner equipment system510, and a second plurality of sensors measuring a second environmental parameter may be positioned upon the outer surface512of the inner equipment system510.

Keeping withFIG.5, in one or more embodiments, a computer system504may be used to interface with the at least one sensor502disposed on the outer surface512of the inner equipment system510. The at least one sensor502provides indication of the environmental parameter and gives a warning to operation personnel in the field. In some embodiments, the computer system504is used to control the operation mechanism508based on the environmental parameter value obtained from the at least one sensor502. In some embodiments, the operation mechanism508is manually operated based on the environmental parameter value. In other embodiments, the operation mechanism508, which is controlled using the computer system504, is mechanically operated and/or is configured to automatically move the plurality of slats506on the movable thermal shroud502into the open configuration or the closed configuration based on the environmental parameter value obtained from the at least one sensor502. For example, the method for automatically moving the plurality of slats506on the movable thermal shroud502can be used to open the shroud automatically based on preset temperature (or certain weather condition) limit or during different operation condition (i.e., start up or shut down).

The at least one sensor of one or more embodiments may be a temperature or weather sensor, such as a pressure sensor or humidity sensor, and/or a gas detector (for example, to monitor H2S or other toxic gas). The sensor may be configured to provide alarms and/or send signals to operate the shroud (open and close) as weather conditions dictate or once a hot or cold spot is detected.

FIG.6is a block diagram of a computer system600used to provide computational functionalities associated with described algorithms, methods, functions, processes, flows, and procedures as described in the instant disclosure, according to an implementation. The illustrated computer602is intended to encompass any computing device such as a high-performance computing (HPC) device, a server, desktop computer, laptop/notebook computer, wireless data port, smart phone, personal data assistant (PDA), tablet computing device, one or more processors within these devices, or any other suitable processing device, including both physical or virtual instances (or both) of the computing device.

In addition, requests may also be sent to the computer602from internal users (for example, from a command console or by other appropriate access method), external or third-parties, other automated applications, as well as any other appropriate entities, individuals, systems, or computers.

Each of the components of the computer602can communicate using a system bus603. In some implementations, any or all of the components of the computer602, both hardware or software (or a combination of hardware and software), may interface with each other or the interface604(or a combination of both) over the system bus603using an application programming interface (API)612or a service layer613(or a combination of the API612and service layer613. The API612may include specifications for routines, data structures, and object classes. The API612may be either computer-language independent or dependent and refer to a complete interface, a single function, or even a set of APIs. The service layer613provides software services to the computer602or other components (whether or not illustrated) that are communicably coupled to the computer602. The functionality of the computer602may be accessible for all service consumers using this service layer. Software services, such as those provided by the service layer613, provide reusable, defined business functionalities through a defined interface. For example, the interface may be software written in JAVA, C++, or other suitable language providing data in extensible markup language (XML) format or other suitable format. While illustrated as an integrated component of the computer602, alternative implementations may illustrate the API612or the service layer613as stand-alone components in relation to other components of the computer602or other components (whether or not illustrated) that are communicably coupled to the computer602. Moreover, any or all parts of the API612or the service layer613may be implemented as child or sub-modules of another software module, enterprise application, or hardware module without departing from the scope of this disclosure.

The computer602includes an interface604. Although illustrated as a single interface604inFIG.6, two or more interfaces604may be used according to particular needs, desires, or particular implementations of the computer602. The interface604is used by the computer602for communicating with other systems in a distributed environment that are connected to the network630. Generally, the interface604includes logic encoded in software or hardware (or a combination of software and hardware) and operable to communicate with the network630. More specifically, the interface604may include software supporting one or more communication protocols associated with communications such that the network630or interface's hardware is operable to communicate physical signals within and outside of the illustrated computer602.

The computer602includes at least one computer processor605. Although illustrated as a single computer processor605inFIG.6, two or more processors may be used according to particular needs, desires, or particular implementations of the computer602. Generally, the computer processor605executes instructions and manipulates data to perform the operations of the computer602and any algorithms, methods, functions, processes, flows, and procedures as described in the instant disclosure.

The computer602also includes a memory606that holds data for the computer602or other components (or a combination of both) that can be connected to the network630. For example, memory606can be a database storing data consistent with this disclosure. Although illustrated as a single memory606inFIG.6, two or more memories may be used according to particular needs, desires, or particular implementations of the computer602and the described functionality. While memory606is illustrated as an integral component of the computer602, in alternative implementations, memory606can be external to the computer602.

The application607is an algorithmic software engine providing functionality according to particular needs, desires, or particular implementations of the computer602, particularly with respect to functionality described in this disclosure. For example, the application607can serve as one or more components, modules, applications, etc. Further, although illustrated as a single application607, the application607may be implemented as multiple applications607on the computer602. In addition, although illustrated as integral to the computer602, in alternative implementations, the application607can be external to the computer602.

There may be any number of computers602associated with, or external to, a computer system containing computer602, each computer602communicating over network630. Further, the term “client,” “user,” and other appropriate terminology may be used interchangeably as appropriate without departing from the scope of this disclosure. Moreover, this disclosure contemplates that many users may use one computer602, or that one user may use multiple computers602.

In some embodiments, the computer602is implemented as part of a cloud computing system. For example, a cloud computing system may include one or more remote servers along with various other cloud components, such as cloud storage units and edge servers. In particular, a cloud computing system may perform one or more computing operations without direct active management by a user device or local computer system. As such, a cloud computing system may have different functions distributed over multiple locations from a central server, which may be performed using one or more Internet connections. More specifically, cloud computing system may operate according to one or more service models, such as infrastructure as a service (IaaS), platform as a service (PaaS), software as a service (SaaS), mobile “backend” as a service (MBaaS), serverless computing, artificial intelligence (AI) as a service (AIaaS), and/or function as a service (FaaS).

As discussed herein, conventional thermal shroud designs have challenges related to visibility and accessibility. However, movable thermal shrouds according to embodiments of the present disclosure may be movable (manually or automatically) relative to a fixed mounting body frame that allows inspectors to conduct inspection activities, operators to monitor the shell temperature, and personnel to perform inspection without the need of dismantling and reinstalling the thermal shroud.
