Title: Process treatment of gases
IPC: B01D53/26
Filed: 1960-11-01
Abstract: 888,266. Drying gases. ESSO RESEARCH & ENGINEERING CO. Nov. 1, 1960 [Dec. 1, 1959], No. 37488/60. Class 34(1) A method of drying flue gases from the regeneration of a platinum group metal hydroforming catalyst comprises withdrawing the hot flue gases from the reactor vessel, passing the gases through a tower for countercurrent contact with a cool scrubbing liquid to remove corrosive acid gases and cool the flue gases, passing these gases through a bed of solid desiccant to dry the gases preparatory to recycling to the reactor vessel and simultaneously drying and regenerating an exhausted bed of solid desiccant with a stream of hot flue gases by passage therethrough, combining the desiccant regeneration gases with the main stream of gases prior to their entry to the scrubbing tower withdrawing a stream of cooled and dried recycle flue gases, which stream is passed through the hot bed of freshly regenerated desiccant and recombining the stream of cooling gases with the main stream of cooled, dried recycle flue gases and recycling the same to the hydroformer reactor undergoing regeneration. The flue gases from a reactor vessel in which regeneration of the catalyst occurs are passed via lines 10, 11, 12, heat exchanger 13, line 14, cooler 15 and line 16 to a scrubbing tower 17, wherein they pass in countercurrent to cool water or alkaline liquid for cooling and removal of corrosive acid gases, and then the gases pass through line 20, and fourway valve 21 into a drier tower 22 or 23 wherein the gases are dried to about 15 parts per million of water by contact with a solid desiccant, e.g. activated alumina, silica gel or certain zeolites. The gases are thereafter recycled to the reactor vessel via line 25, a compressor 26, the heat exchanger 13 and a furnace 29. Simultaneously the desiccant in either tower 22 or 23 is regenerated by a portion of hot flue gases passing from lines 14, 31, valve 32 and line 33, into which line 33 also flows a stream of hot gases from lines 12, 34 upstream of the heat exchanger 13. The united stream passes through a line 36 and the valve 24 into the tower from which they flow through valves 38 and lines 39, 16 into the scrubbing tower 17 mixed with the main stream of gases.

Abstract: 1,183,124. Ultrasonic inspection devices; couplings. BRITISH IRON & STEEL RESEARCH ASSOCIATION. 19 July, 1968 [16 Aug., 1967], No. 37613/67. Headings H4D and H4J. A particulate material applied to a test object provides acoustic coupling between the object and one or more ultrasonic transducers. This form of coupling is applicable where the object surface is rough or hot. The material is applied by gravity feed, by a movable powder applicator, or from a powder gun, and may form a layer which can be compacted by a roller. The transducer is applied to the layer by direct hand pressure or by a device exerting a 10-500 p.s.i. pressure, and may be cooled (e.g. by motion of the material). Alternatively the transducer(s) may be mounted in a roller which follows the compacting roller, or the ultrasonic energy may be transmitted to the object through a stream of the material falling freely on to the object. For testing hot objects (800-1200‹ C.) the material melting point may be above or just below the surface temperature of the object. Coupling materials specified are powdered metal (e.g. iron, nickel, aluminium), the oxides, nitrides, borides or carbides of metals, and ceramic or cermet powders including graphite, boron nitride, silica, alumina or magnesia: particle size is up to 100 microns.

Abstract: 1,056,665. Weighing apparatus. HOWE RICHARDSON SCALE CO. Sept. 21, 1964 [March 11, 1964], No. 38350/64. Heading G1W. [Also in Division G4]. In a batch weighing apparatus, material is delivered to a weighing device and in response a counter preset to the required weight is counted down until a reference value is reached when delivery is interrupted. A first material is delivered to a hopper by both main and dribble feeds with counting down until a counter reading preselected by switches is reached when the main feed is terminated leaving only the dribble feed. The dribble feed is terminated when a second preselected reading is reached, this reading being in general non-zero to allow for delays. The final counter reading is tested to see if it falls within limits preset on switches and a lamp lit if it does not. However if it does, the counter is preset to the required weight of a second material and the above procedure repeated, and so on until all required materials have been delivered to the hopper when the mixture is released through the bottom of the hopper. A visual read-out of the counter is also provided. Counters. The counter is a bidirectional decade ring counter Fig. 6 &c, (not shown) utilising silicon controlled current conducting switches, one per stage. Fig. 14 (not shown) shows a modification for the case when each pulse fed to the counter is to represent two, not one. The stages of the units decade now represent 0, 2, 4, 6, 8, 0, 2, 4, 6, 8 instead of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, respectively and provision is made for carry to or borrow from the tens decade on transitions between the first 8 stage and the second 0 stage of the units decade as well as on transitions between the second 8 stage and the first 0 stage. Only one stage of the units decade is on at any one time as before. Similar modifications can be made when each pulse is to represent three, &c.

A supercharged hydraulic rotary pump has a cylindrical rotor 20 with outwardly-sliding radialvanes 24 engaging with an abutment ring 13 that is held against an end cover 11 by the pressure of a spring 16 and fluid in an outlet, or pressure, chamber 27 acting on a check-plate 14. The chamber 27 is connected to an outlet bore 48 by a throttling bore 46 and a larger bore 47 to which a chamber 45 for a spring-loaded nozzle 39 is also connected by way of a bore 50. The incoming fluid passes to the working chambers between the vanes through bores 37, 36, a jet pipe 33, the nozzle 39 and a bifurcated-diffuser channel 51. At low rotor-speeds the nozzle abuts the jet pipe; and when the speed rises the pressure in the chamber 45 becomes appreciably less than that in the chamber 27 due to the throttling action of the bore 46, thus causing the nozzle to retract and a proportion of the outgoing fluid to recirculate. Extra fluid is drawn through the jet pipe by the recirculating fluid and thereby prevents cavitation in the working chambers. The outer surface of the jet pipe may be tapered or straight, Figs. 6 to 7a (not shown). Excess pressure in the bore 47 is relieved by way of the chamber 45, a spring-loaded valve, Fig. 4 (not shown), in a bore 57, and the bore 36.

Filed: 1959-11-16
Abstract: <PICT:0963451/C4-C5/1> Benzene is separated from a mixture containing benzene, n-heptane, methylcyclohexane and possibly other relatively high-boiling hydrocarbons by submitting the mixture to fractional distillation so as to obtain the benzene and n-heptane as an overhead vapour leaving the methylcyclohexane and other heavy impurities as a liquid residue, and subsequently separating the benzene and n-heptane by using an azeotropic or pseudo-azeotropic agent to enhance the volatility of the n-heptane.  A feedstock containing 42% benzene, 1.0% n-heptane, 0.3% methylcyclohexane and other hydro-carbons passes through line 1 into section I of a fractionating column; and a fraction containing very little benzene is discharged through line 3. Vapours comprising benzene and nearly all the n-heptane enter section II which also contains acetone and water; and vapours containing n-heptane and the auxiliary agents are withdrawn overhead, and passed to condenser VI.  Some of the condensate is returned via line 5 to section II as reflux, and the remainder is passed to water-extraction column IV for removal of the acetone from the n-heptane.  The reflux liquid descending section II is collected on a decanting-tray 2a; and some of the hydro-carbon liquid weirs over this tray into section I. The aqueous layer on tray 2a and the remainder of the hydrocarbon layer flow into stripping section III, which is also supplied via line 9 with an aqueous solution of entraining agent from column IV. The vapours from the head of section III are passed via line 11 into section II.  A mixture of benzene and water is withdrawn from the base of section III, and is passed to decanter V.
