... 949,119. Refrigerating. PETROCARBON DEVELOPMENTS Ltd. Dec. 19, 1962 [Dec. 21, 1961], No. 45892/61. Heading F4H. A refrigeration system comprises compressing helium in a two-stage reciprocating compressor 1, cooling the helium firstly in a water fed cooler 2, secondly by indirect heat exchange with returning helium in an exchanger 3 and thirdly by expansion in a radial inward flow turbine 4, then contacting the helium with an adsorbant 5, e.g. activated carbon, to remove nitrogen and oxygen, further cooling the helium firstly by indirect heat exchange with returning helium in a further exchanger 6 and secondly by expansion in a second radial inward flow turbine 7 to atmospheric pressure, using at least part of the helium to perform a refrigeration duty in a cold chamber 9 and returning the helium to the compressor 1 for recycling. Part of the helium by-passes the cold chamber 9 in a bypass line 10 containing a valve 11 controlled by a device 12 sensitive to the temperature at the inlet to ...

... 971,362. Cold separation of gas mixtures. PETROCARBON DEVELOPMENTS Ltd. Sept. 25, 1963 [June 30, 1962], No. 3745/62. Heading F4P. Carbon dioxide is freed of more and less volatile impurities, e.g. methane and butane respectively by two-stage separation in high and low pressure columns 9, 13, the former having a reflux condenser 14 which serves as the reboiler for column 13 and from which the gaseous methane fraction is discharged through duct 21 whilst partly purified liquid carbon dioxide collecting at the bottom of column 9 is withdrawn and expanded at a valve 23 into column 13 from the base of which liquid butane is withdrawn through a duct 24 whilst pure carbon dioxide is withdrawn as top gas. The effluent gas is warmed in an exchanger 16, compressed at 17 cooled in exchangers 18, 16, condensed in a reboiler 11 of column 9 and liquid carbon dioxide is collected in a tank 12. A portion thereof is withdrawn through a duct 27 and is expanded at a valve 28 into the head of column 13 to ...

... 1,021,453. Cold separation of gas mixtures. PETROCARBON DEVELOPMENTS Ltd. Nov. 18, 1963 [Nov. 29, 1962], No. 45233/62. Heading F4P. Impure compressed carbon dioxides is freed of low boiling-point impurities including C 1 -C 4 hydrocarbons by passing the feed stream through oil filters 10, a water separator 13, driers 15, coolers 17, 19, 21 and expanding at a valve 24 into a first rectification column 25, withdrawing crude liquid carbon dioxide therefrom through a line 29, expanding at a value 30, evaporating in a reflux condenser 27 traversed by overhead gaseous effluent of the column 25, heating the carbon dioxide vapour at 32, adding air from a compressor 37, heating the mixture to about 400‹ C. in an exchanger 39 and an electric heater 41 and subjecting the mixture to catalytic oxidation at 43 thereby converting the hydrocarbons to carbon dioxide and water vapour, and after cooling and drying passing the mixture through lines 49, 50 to a second rectification column 22 from which product ...

Purification of hydrogen

Номер: GB0001033341A
Автор: CHARLESWORTH PAUL LANE, RUHEMANN MARTIN SIEGFRIED WILL, RUHEMANN MARTIN SIEGFRIED WILLIAM
Принадлежит:

In a process for purifying H2 by condensing out CH4 impurity, the f.p. of the CH4 is depressed by at least 1.5 DEG K, preferably 3-5 DEG K, by the presence of C2H6, C2H4, C3H8 or mixtures thereof and the impure H2 is cooled below the f.p. of pure CH4 (90.7 DEG K) but above the depressed f.p. under a superatmospheric pressure (10-50 atm.) such that more hydrocarbon is condensed out and substantially pure H2 is separated from the condensate. The feed gas may be refiner or reformer off-gas containing H2O, C1-C5 alkanes and possibly C2H4, in which case the water and the butanes, pentanes and preferably propane are removed in one or more preliminary drying and condensation steps. Preferred components for depressing the f.p. of CH4 are ethane, in amount 2-33 molar per cent of total CH4 plus C2H6 content, or ethylene, in amount 5-13%. These hydrocarbons may be added to the H2/CH4 mixture when it is initially free of other hydrocarbons. N2, CO or other impurities boiling below the f.p. of the hydrocarbon ...

... 943,669. Cold separation of air. PETROCARBON DEVELOPMENTS Ltd. Nov. 1, 1962 [Nov. 3, 1961], No. 39496/61. Heading F4P. In a single-column air rectification process for the production of liquid oxygen, at least part of the feed air which is at a relatively low pressure e.g. 8 atmos. is further compressed in a brake blower or blowers 15, 151 of turbines 16, 161 through which is expanded at least part of the feed air to produce cold for the process. As shown the further compressed air is withdrawn from a feed line 10 through a line 11 and is thereafter cooled in a preliminary exchanger 17 followed by exchangers 18, 19 traversed by counterflowing waste effluent leaving the head of column 21 through a line 25 and the so cooled feed air is liquefied in the reboiling coil 20 of the column, sub-cooled in an exchanger 23 traversed by a mixture of air and waste gas having been expanded in turbine 16, and finally expanded at a valve 24 into the column 21. The mixture of air and waste ...
