Patent GB-913703-A (GB)
Title: Process for the production of ethylene oxide
IPC: C07D301/10
Filed: 1961-05-23
Abstract: Ethylene oxide is produced by contacting ethylene and oxygen and at least one inert gas with a silver catalyst at between 150 and 450 DEG C. in a first reaction zone, dividing the effluence into two unequal streams, the smaller being led to a second reaction zone similar to the first, separating ethylene oxide from the effluence from the second zone and discarding the remaining gases; the larger stream is passed to a separating zone where the ethylene oxide is recovered and the remaining gases recycled to the first reaction zone.  The concentration of ethylene in the first reaction zone may be from 2-20% by volume and that of oxygen from 5-20% by volume, but preferably at or below 9%.  The silver p  catalyst may be metallic silver on a support and may have a modifying agent added, e.g., ethylene dichloride or a polychlorinated polyphenyl compound.  In the first reaction zone, the temperature may be from 250-300 DEG C. and the pressure from 1-36 atm., preferably 6.25-20.25 atm., with a contact time sufficient to effect a 30-45% conversion of ethylene. In the second reaction zone the preferred conditions are 260-325 DEG C. and 8-11.5 atm., with a contact time sufficient to effect a 75-85% conversion of ethylene.  In the second reaction zone the temperature is higher and the pressure lower than in the first.  The amount of effluence from the first reaction zone that passes to the second may be not more than 15%.

Abstract: 304,333. Cooper, C., Henshaw, D. M., and Holmes & Co., Ltd., W. C. July 15, 1927. Materials for purifying ; scrubbers. - Crude fuel gas is dehydrated, purified, and cooled by contact with concentrated solutions of salts, for example, ammonium salts, which absorb water without correspondingly taking up free ammonia. The solution should be of such specific gravity that the tars and other condensed constituents, insoluble in water, will float upon the surface. The crude gas is admitted by the pipe 1, 4 into the lower end of a scrubber 3 in which it is dehydrated by contact with absorbent liquid and passes away through a pipe 25 to a cooler 26. The liquid flows through the pipe 6 into the compartment 7 of a tank wherein it is exposed to the atmosphere and the absorbed water evaporated therefrom. The liquid is withdrawn from the central compartment of the tank by a pump 12 and circulated through a coil 13 back to the scrubber. The coil is heated by a portion of the liquid passing through the pipe 14 into contact with hot crude gas in a coke tower 16 and thence into a distributing tray 20 disposed above the coil. The liquid then flows over a steam coil 22 into a tray from which it returns through a pipe 21 into the tank. The gases may be brought into contact with tar or constituents of tar in a liquid state to facilitate the removal of liquids other than water. Specifications 248,841, 266,825, 268,429.

Title: Methods and apparatus for extracting ammonium bicarbonate from water containing ammonia and carbonic acid, such as gas washing water
Inventor: GRAS WILHELM
IPC: C01C1/26
Filed: 1952-07-31
Abstract: <PICT:0710617/III/1> Ammonium bicarbonate is obtained from water containing ammonia and carbonic acid by dividing the water into two parts, passing steam through the first part to distil off the dissolved ammonia and carbonic acid gas, passing the resultant mixture of steam and gases with more steam through the second part at a temperature such as to distil from it the dissolved carbonic acid gas but substantially none of the ammonia, and cooling the final resultant gas mixture to yield crystals of bicarbonate.  Gas from the degasification of hard coal or lignite is washed with water in tower 1 and the water containing ammonia and carbonic acid continuously passing from the bottom of the tower is divided into two streams 2, 3.  Stream 2 is preheated in exchanger 4 and passes to the top of first separator 5 and flows down therein over spaced platforms, while steam to raise the temperature to about 100 DEG C. is passed over and through it in the opposite direction.  Water from the base of separator 5 flows through exchanger 4 to preheat incoming stream 2 and out at 6 to waste.  Stream 3 after preheating in exchanger 9 passes to the top of second separator 8 and the mixture of steam, ammonia, and carbon dioxide. driven off in separator 5 and fed through pipe 7, together with additional steam at a lower temperature, e.g. 80-97 DEG C. than that in separator 5 passes upwards over and through it and further carbonic acid gas is driven off.  The water still containing ammonia passes from the base of separator 8, through exchanger 9 to preheat incoming stream 3, and then through pipe 10 with a cooler back to washing column 1.  The gas mixture from the top of separator 8 passes to crystallizing closed drum 13, the external surface of which is cooled by liquid from nozzles 14.  Crystals of bicarbonate are deposited on the walls of drum 13 and are scraped off by rotary spiral screw 15, which delivers them to trough 16, whence they are fed by conveyer 17 to hopper 18, and thence to centrifuge 19 to separate mother liquor.  Remaining gases consisting of surplus carbon dioxide, hydrogen sulphide, and hydrogen cyanide are withdrawn at 20.  The ratio of the two parts into which the water is divided may be adjusted volumetrically to ensure that the ratio of ammonia from the first part to carbon dioxide from both is approximately equimolecular.
