摘要： Method of reliquefying gas resulting from the evaporation of a ship''s cargo of liquefied gas which utilizes a compression refrigerator having two refrigerant loops in one of which the compressed refrigerant is expanded in a turbine and in the other of which it is expanded without the performance of external work. The expansion turbine and a gas turbine which can be fueled by the gas provide the power for compressing the refrigerant, and the gas is reliquefied by heat exchange with cold expanded refrigerant in the second loop. In one embodiment open loops are used with the gas providing the refrigerant.

摘要： Processes are provided for the oxidation of olefinically unsaturated compounds to oxirane compounds, vic-glycols and vichalohydrins in which the olefinically unsaturated compound, carbon dioxide water and hypohalite are brought into intimate contact so as to form vic-halohydrin, and if desired, exposing the vic-halohydrin to aqueous bicarbonate so as to form oxirane compound and/or vic-glycol. Bicarbonate is formed as by-product in the production of vic-halohydrin and this bicarbonate may be used to convert the vic-halohydrin to oxirane compound or vicglycol. Also carbon dioxide is formed as by-product during the conversion and this is advantageously used to provide carbon dioxide required for the production of the vic-halohydrin. Similarly, the hypohalite is conveniently formed by electrolysis of metal halide derived as by-product of the conversion of vichalohydrin to oxirane compound or vic-glycol.

摘要： 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 liquid carbon dioxide is withdrawn at 56 at - 15‹ C., further cooled in an exchanger 57 to - 30‹ C. and led off as product through a line 58 to a storage container 59. Heat exchanger 21 serves as the reboiler for column 22 whereas exchanger 57 serves as the reboiler for column 25 assisted by an exchanger 52 through which passes overhead gas from column 22.

摘要： A light gas, namely hydrogen or helium, of increased purity is obtained from a gaseous mixture consisting predominantly of the light gas by passing the mixture through a rotating gas centrifuge under conditions such that gaseous impurities are condensed and a light gas stream of increased purity is recovered. The process may be applied to a light gas concentrate obtained from a gaseous mixture by separation of the constituents other than the light gas by low-temperature condensation, in which case a gas expansion turbine used to produce refrigeration for the process may be used to drive the gas centrifuge.
