Title: Improved manufacture of alkali sulphides
IPC: C01B17/22
Filed: 1933-12-28
Abstract: Anhydrous alkali sulphides free from carbonates or hydroxides are obtained by treating an alkali carbonate or an alkali carbonate containing alkali hydroxide with hydrogen sulphide or carbon oxysulphide in the presence of a reducing or inert gas such as carbon monoxide, hydrogen, methane, or nitrogen at an elevated temperature which may be 400--800 DEG  C.  As initial material, an alkali sulphide containing alkali carbonate or hydroxide may be used, or materials adapted to give rise to such sulphide such as sodium sulphate and water gas, whilst instead of hydrogen sulphide or carbon oxysulphite components giving rise to these gases, such as hydrogen or carbon monoxide and sulphur vapour may be employed.  When using hydrogen sulphide, gas mixtures containing 5--15 per cent thereof are generally employed, but in operating under reduced pressure concentrations of 15--25 per cent may be used.  Technical gas mixtures containing both hydrogen sulphide and hydrogen and/or carbon monoxide may be used.  In one example, sodium carbonate is treated at 650 DEG  C. with a mixture of 90 per cent hydrogen and 10 per cent hydrogen sulphide.  In a second example sodium carbonate is treated at 600 DEG  C. with a mixture of 7,5 per cent of hydrogen sulphide and 92,5 per cent of hydrogen, with recirculation of spent gas after removal of water and carbon dioxide and addition of further hydrogen sulphide.  In this way a ratio CO : H2 = 0,38 in the circulating gases is ultimately obtained.  In a third example, treatment is effected with a gas mixture containing, in addition to hydrogen sulphide, hydrogen, and carbon monoxide, small percentages of methane, carbon dioxide, nitrogen, and water vapour.  In a further example the gas mixture used is a mixture of water gas with gases obtained by the distillation of crude mineral oil.  In a fifth example, sodium sulphate reduced with coal at 750 DEG  C. in the presence of carbon monoxide, is treated at 650 DEG  C. with hydrogen sulphide containing reducing gases.  Alternatively \ba1/2\be--1 per cent of hydrogen sulphide may be added to the carbon monoxide in the reducing step.  In a further example, sodium sulphate reduced by water gas at 700 DEG  C. is treated with gases containing hydrogen sulphide.  Alternatively, 1--2 per cent of hydrogen sulphide may be added to the water gas in the reducing step.  When potassium carbonate is used higher temperatures and lower concentrations of hydrogen sulphide are required.

Abstract: 1352904 Purifying hydrocarbons by adsorption UNION CARBIDE CORP 5 Aug 1971 [6 Aug 1970] 36884/71 Heading C5E In a process for removing sulphur compounds (e.g. hydrogen sulphide, carbonyl sulphide, mercaptans, sulphides and disulphides) from a hydrocarbon feed by adsorption on a primary bed of molecular sieve adsorbent, the bed is desorbed and purged using a readily condensible paraffin (e.g. a C 3-5  normal or iso-paraffin) desorbent in the vapour phase at 400-650 F., the desorbent is condensed to form a solution containing at least 50 wt. per cent of the sulphur compound desorbate and at least 30 wt. per cent of the total desorbent, this solution is passed in the liquid phase through a smaller secondary molecular sieve bed to adsorb the sulphur compounds, and the sulphur compounds are desorbed from the secondary bed with a hot purge gas (e.g. of H 2 , CH 4 , N 2  or CO 2 ). The hydrocarbon feeds treated are natural gas and gasoline-boiling range natural gas condensates, crude oil fractions and hydrogenation or distillation products of coal. The sieve can be a sodium, potassium, calcium, magnesium or strontium zeolite X, calcium zeolite A, a natural or synthetic mordenite, or a zeolite Y or L. The adsorption in the primary bed can be carried out in either the vapour or liquid phase. A condensate feed 10 containing H 2 S is passed in the liquid phase through a primary bed 14 of sodium zeolite X to produce a H 2 S-free stream 18. The bed is then drained and desorbed with propane vapour 20 at 550 F. The desorption effluent is cooled at 28 to form a solution of H 2 S in liquid propane at 200 p.s.i.g. and below 100F. in the accumulator 32. The solution is passed through a secondary bed 40 of sodium zeolite X to adsorb H 2 S and recover a propane stream 42. The bed 40 is then drained and purged with gaseous natural gas to remove H 2 S.

Abstract: <PICT:0350967/III/1> <PICT:0350967/III/2> Apparatus for distilling liquids consists of parallel horizontal tubes arranged in rows vertically above one another, the liquid being caused to trickle over the tubes in these layers by guiding plates arranged around and between the tubes.  Furnace gases, steam, heated liquids, &c., may be passed through the tubes, preferably entering at the lowest row, or the tubes may be electrically heated.  When furnace gases are employed, a layer of heat-distributing material, e.g. aluminium, is placed on the tubes and this may be protectively coated to prevent erosion.  In the form shown, three rows of aluminium coated tubes 3, 4, 5 are arranged vertically above one another in a vessel 9 to which the liquid to be distilled is conveyed by a pipe 1.  From the pipe 1 the liquid passes to a distributing channel 2 whence it flows on to the pipes, being guided thereto by plates 6 arranged to prevent spurting of the liquid.  From the tube 5 the heated liquid falls on to slightly inclined evaporating plates 7 and passes out by a pipe 8, the distillate leaving by a pipe 19.  Hot gases from a combustion chamber 11 enter the tubes 4, 5 at 12 and pass from an end chamber 13 through the tubes 3 into a chamber 14, through a flue 15 into an enclosure 10 surrounding the vessel 9 and thence to a flue 18.  To protect the ends of the tubes, an intermediate chamber 16 is provided, and to allow for expansion, the tubes are supported at one end by a membrane 17.  An example is given describing the distillation, under a vacuum of 10-20 millimetres of mercury, of an oil 86 per cent of which boils between 190 DEG  and 400 DEG  C.
