摘要： A process for separation of gases into two components of different boiling points, for example in the separation of ethane from natural gas, comprises a first separation tower (V1) and a second separation tower (V2). Liquid in stream (5) from a bottom of the first tower is expanded and cooled and is then communicated in stream (6) to the second tower at a lower pressure. Gas from the second tower is communicated back to the first tower so that the first component in stream (10) is extracted from the top of the first tower and the second component in stream (11) is extracted from the bottom of the second tower. A third tower (V3) acts as a recycle fractionator upon the gas in stream (7) extracted from the top of the second tower with that gas being compressed into the third tower which is at high pressure. The liquid in stream (5) from the bottom of the first tower is used to cool a condenser (E6) at the top of the first tower (V1) and to cool the material from the recycle fractionator (V3) as it is returned to the top of the first tower.

摘要： A process for distillation of two materials of differing boiling points particularly propane, ethane or carbon dioxide from natural gas is described in which the conventional distillation tower is divided into a first tower (102) at higher pressure than a conventional tower and a second tower (104) at rower pressure. Liquid drawn from the first is expanded to the lower pressure through two or more stages (111,112) with cool extracted (65,62) at each stage and used to cool (65,62) gas (51) withdrawn from the top of the first tower to keep the top tray at a required temperature. Gas (19) withdrawn from the second tower (104) is compressed and cooled for return to the first tower as a reflux. The use of the cool from the expanded liquid and the use of the two towers provides an improved thermo-dynamic efficiency and avoids the use of costly turbo-expanders.

摘要： Hydrogen sulphide is extracted from a supply gas as elemental sulphur using a reactor comprising a vertical cylinder (12) containing a downwardly moving bed of catalyst. Catalyst extracted at the bottom is elevated by a stream (26) of the supply gas in an unheated condition and is cooled by contact with the gas and subsequently by contact with suppiy air (11) to a temperature of the order of 150°F for injection into the top of the cylinder (12). A plurality of slip stream condensers (54-57) arranged seriatim along the length of the cylinder each act to extract 60% of the total gas flow upwardly in the cylinder and return the extracted gas downstream of the next adjacent extraction point so that the whole of the gas is extracted into one or more condensers for condensation of the sulphur formed on the catalyst. A water vapour condenser (100) is positioned downstream of the condensers to extract water vapour to further complete the reaction. The ratio of hydrogen sulphide to sulphur dioxide is maintained less than 2:1 and is corrected at a later stage of the process by injection of hydrogen sulphide.
