Diagnostic concept Hydrogen permeation through themetal structure or leakages due to defective seals is aserious risk factor in hydrocarbon processing units. The
Endress+Hauser diagnostic concept built around the diagnostic chamber adresses this risk while also generating
valuable information about the application. By monitoring
and analyzing selected physical parameters such as pressure trends or the chemical composition of fluids inside thediagnostic chamber, operators are provided valuable datafor predictive maintenance.
• Basic diagnostics: On demand detection of system pressurization. Fluid composition analysis can be performed
to evaluate the system’s condition.
• Advanced diagnostics: Continuous monitoring of systempressurization, generating a data record for further trend
analysis (baseline comparison) and fluid composition
analysis.

Pressure trend analysis By comparing the pressure trend
inside the diagnostic chamber with its theoretical baseline
over a period of time, indications toward the reactor internals and structural integrity can be drawn.
Endress+Hauser provides evidence of the theoretical trend
during the engineering phase, taking into considerationmaterial choices, volumes and design conditions. The data
recorded can be fed into a dedicated data manager suchas the Endress+Hauser Memograph M RSG45, building atamper-proof database and a clear visualization of measured values.
Pressure trends derived from the record provide indications
as to the instrument’s health and help extrapolate mainteance recommendations for every turnaround.
Fluid composition analysis An analysis of the chemicalcomposition and the identification of fluid concentrations
inside the diagnostic chamber (molecule size, delta pressure) can provide valuable information about the nature ofcracks and leaks, their dynamics and their path.
Endress+Hauser offers on-site fluid sampling services using
specialized portable equipment. Our experts analyze theresults and guide you through the subsequent maintenanceplanning while taking into consideration the estimatedresidual life time of the devices surveyed.

Food and beverage In addition to
oil & gas and chemical applications,
Endress+Hauser provides temperature
measurement solutions aimed at
improving bulk and solids storage
applications typically found in the food& beverage industry.

Such reactions cause an increasein temperature (hot spots) which
can be detected through accurate
temperature profiling. Monitoring
environmental conditions inside tanks
and silos is therefore a crucial factor insafeguarding product quality.

built-in webserver for direct and global
access. Data can also be fed into existing ERP systems via standard software
protocols.

Temperature profiling Organic
products such as grain, pellets
or other bulks risk undergoingchemical reactions when exposed
to environmental contaminants,
inevitably spoiling the product.

Level and humidity monitoring
In addition to temperature profiling, silo condition monitoring solutions can also be equiped to measurelevel and humidity parameters. The
complete data is fed into a historical
records database for trend and quality
monitoring.

Temperature transmitters
Getting the most out of your sensor signals
Electronic temperature transmitters are recommended to transform the sensor output signal into a stable and standardized analog or digital communcation signal. Measurement accuracy, electric safety and high flexibility are their key features. Transmitters are available in three types of housings: DIN rail mounted devices suitable for panel installation, headtransmitters for direct installation in thermometer terminal heads or junction boxes and robust field transmitters for directconnection near the process application.

Iplom enhances catalyst life,
process safety and efficiency
Temperature profile monitoring of the catalyst bed

Solutions for the oil & gas industry

Iplom SpA is an italian oil refining
company located near the Metropolitan City of Genoa. With a maximum production capacity of 1.89
m tons per year, Iplom produces
bitumen, diesel oil for automotive
and fuel oil with a very low sulfur
content.
“Thanks to reliable temperature
measurements we are now able toguarantee the safety in the catalytic
reaction process for the entire life
cycle of the catalyst (24 months
or more). The device’s diagnostic
chamber enables us to promptly
detect any anomalies and better
plan future interventions.
The solution from Endress+Hauser
is a true gain in terms of safety andyield.”
Stefano Galli
Instrumentation and analysis
Iplom SpA

Iplom SpA refinery in Busalla, Italy

Iplom SpA seeked to optimize its
refining process, to extend its catalyst life and to increase safety in ahydrodesulfurization (HDS) application through precise 3D temperature profiling.
Summary Given the inevitableprice volatility of its product, Iplom
searched for ways to increase bothprocess efficiency and product quality
to strengthen its position within thehighly competitive oil & gas market.
A focus on plant safety was, as always,
a given.
Endress+Hauser provided a tailormade
temperature profile measurement
solution consisting of an iTHERM
MultiSens Flex TMS02 multipoint
assembly as well as expert guidancefrom configuration to installation,bringing the project to completion intime and on budget.
This solution has led to considerable
improvements by optimizing process
performance, extending catalyst life
and increasing plant safety.

Challenge To ensure safe and efficient chemical reaction control,
operators depend on critical insights
and data from the process as well
as state-of-the-art instruments thatprovide additional safety barriers
against extreme process conditions.
An uneven temperature distribution(hotspots) lead to the fact that thecatalyst degraded faster than necessary and the process was not runningat its peak capacity. Iplom thus set thefollowing targets:• Optimize process monitoring andcontrol, reduce hotspots• Gain meaningful data for future
improvements• Increase catalyst life
• Increase product quality• Further increase plant safety
Solution Our MultiSens Flex multipoint thermometer offered a robust,
single-nozzle, multi-sensor solution
by monitoring the temperature profileof the catalyst bed in a 3D layout. The
device’s on-board diagnostic chamberadds a vital process containment layer.

Iplom enhances catalyst life, process safety and efficiency

and field-tested. The remaining eightsingle-point thermocouples are usedin parallel as reference. The built-in
diagnostic chamber provides valuable
data for monitoring the condition of
the multipoint assembly itself as wellas to detect and contain potential
process leakage. The device is fittedwith a Cerabar PMP71 digital pressuretransmitter and iTEMP TMT182 temperature transmitters communicating
via 4 to 20 mA HART protocol with
Iplom’s DCS system.
Due to the time-critical nature of theplant’s shutdown period, the reactor
needed to be fully operational without
delay. In addition to delivering the
hardware, Endress+Hauser performed a series of services that helped
streamline the entire replacement
process from quotation to installation:
Endress+Hauser iTHERM MultiSens Flex TMS02 with built-in diagnostic chamber

Application details The harsh process conditions of approximately 75
bar and 430 °C under which the HDS
reactor is operating, as well as thepresence of corrosive chemicals suchas sulfur and hydrogen, called for arobust and long-lasting solution. The
multipoint assembly was installed on
the level 4 catalyst bed of the diesel
oil reactor to monitor the temperature at two different heights. It now
enables Iplom to establish a precise

temperature profile, to maximize
process efficiency and to yield a highquality product according to strict
industry specifications.
Solution components
The multipoint thermometer chosen
was a standardized iTHERM MultiSens Flex TMS02 in a configuration
carrying 20 measuring points, 12 ofwhich are innovative TS901 ProfileSens inserts currently being developed• Project management• Detailed instrument engineering• 3D routing calculations andinstallation layout engineering• Factory acceptance test
• Installation supervision
Our experienced technicians guided
the process all the way to completionin time and on budget.
Results Iplom tested the MultiSens
Flex TMS02 with the new ProfileSens
cable sensors in substitution of a traditional system and are very pleased
with the devices’ performance as wellas the services provided.
