Abstract: 1,145,332. Photo-electric level indicators. UNIVERSAL OIL PRODUCTS CO. May 9, 1966 [May 10, 1965], No.20418/66. Heading G1A. The level of liquids or fluent solids or the boundary between liquid, or gaseous phases in a container is located by investigating absorption of radiation passing through the medium or mediums in the container by means of a source vertically travelling inside a conduit in the container and a detector vertically travelling in synchronism with the source outside the container. In Fig. 1 a separator is shown for separating a mixture of hydrocarbon and hydrofluoric acid which enters at 11 and whose components leave at 12 and 13: inside the separator there are three distinct phases, hydrocarbon at 36, the mixture at 38 and the acid at 40. To detect the boundaries of the phases 37 and 39 a radio-active source enclosed in a lead block 16 having an outlet slit is moved up and down the conduit 14, either by the pulley system as shown or a piston and rod system, and which transmits radiation through the liquids to a detector 18 suspended outside the container and travelling in synchronism with the source along guide tracks 20. Instead of the track a vertical shield may stop the detector swinging about. At the base of the conduit is a lead shield 15 incorporating a condensation drain 15a and at the base of the track is another source 42 for calibrating the recorder 23. Signals from the detector may be used to control the operation of the separator. The conduit 14, instead of passing completely through the separator, may extend only part of the way, either from the top or the bottom or may include a right-angled bend to leave via a side wall. Suggested sources are radium, cesium europium and thorium and suggested detectors are geiger counters, proportional counters, scintillation counters and ionization chambers.

Abstract: 275,273. G³lker, F. July 30, 1926, [Convention date]. Catalytic apparatus; catalytic agents, treatment of; hydrogen, catalytic production of from steam and carbon monoxide.-The production of hydrogen by treating carbon monoxide or gases, such as water gas, containing carbon monoxide with steam in the presence of a catalyst is performed in the presence of substances capable of absorbing carbon dioxide under the conditions of working, the temperature being such that carbon dioxide is not appreciably liberated from the absorbing substance, so that steam may be employed in an amount which at the most is only slightly in excess of that theoretically necessary. The catalyst and the absorbent for carbon dioxide may be used in the form of a chemical compound or they may be mixed together and used in powder form or as briquettes. Suitable absorbents for carbon dioxide are alkaline-earth oxides, particularly lime, which may be prepared in situ from marble, calc-spar, and similar minerals. The catalysts need not be previously activated or otherwise prepared for use, but may be mineral substances such as spathic iron ore and bauxite. The catalyst and the absorbent for carbon dioxide may be reactivated or regenerated by treatment with air or steam at a raised temperature. The process may be carried out in apparatus comprising chambers a<1> - - a<3> filled with a catalyst and an absorbent for carbon dioxide and heated indirectly through channels d; the reagents are admitted at b and the reaction products withdrawn at c.

Title: Separation of carbon dioxide from ammonia
Inventor: VASAN SRINI
IPC: C01C1/02
Filed: 1961-06-07
Abstract: Carbon dioxide is removed from a gaseous mixture containing NH3 and 2 p.p.m.-1% CO2 by passage through a molecular sieve comprising a bed of activated zeolite, e.g. chabazite, having voids whose smallest dimension is at least 4.A.U.  After the zeolite ceases to adsorb CO2 to the required extent, it may be reactivated by indirect heating and flowing heated purified NH3 in the reverse direction through the zeolite which is then cooled with CO2-free NH3, and both the NH3 may be returned to the first CO2 separation.  The gas mixture containing 2 p.p.m.-1% CO2 is obtained by feeding a gas containing NH3, more than 1% CO2, H2O vapour and other fixed gases via line 5 to absorber 1 which contains a cooled aqueous solution, e.g. a base capable of reversible combination, with CO2 such as Na2 CO3, K2CO3, water soluble amines and alkylolamines such as mono-, di- and tri-ethanolamine and propanolamines.  Absorber may be a packed tower, bubble plate column or gas washer with cooling coils.  The solution from 1 is fed via line 4 to stripping column 2 where it is heated to drive off NH3 only which is returned to 1 via line 5.  CO2 free gas is withdrawn from 1 via line 7.  The solution from 2 is fed via lines 6 and 15 to heat exchanger 16 and via line 17 to, e.g. fractionating column 18 with packing or bubble plates. Heater 19 is fed with high pressure steam and solution from 18 is fed in part via 20 to heater 19, returning by line 21, and remainder is fed via line 26 to heat exchanger 16 via line 27 to water cooler 28, via line 29 to storage tank 30 and via line 31, pump 32, cooler 33 and line 34 back to tower 1.  NH3 containing 2 p.p.m.-1% CO2 from tower 1 is then fed via line 9 and valve 55 or 56 to adsorption vessel 10 or 11 which may contain a dessicant, e.g. activated Al2O3 or SiO2 gel, 53 and 54, and zeolite, 51 and 52.  Part of the NH3 is removed via line 61 and valve 32 to storage or further use and the remainder is fed via optional heater 64 and valves 67 or 68 <PICT:0931051/III/1> to regenerable one of the beds 10 or 11 which are also heated, e.g. electrically or by heating coils, in the adsorbent.  The adsorbed-gas from 10 or 11 is returned via line 69 to 1.  After regeneration the zeolite is cooled by NH3 drawn from by-pass line 65.  The NH3 used for desorption and cooling is returned via line 69 to 1.
