摘要： An improved, membrane-based method of treating gas evolved during gas/oil separation, to separate the very light hydrocarbon gases, methane in particular, from the heavier hydrocarbons. The membrane acts as a demethanizer and establishes a vapor/liquid equilibrium during phase separation that is different than would otherwise obtain. This can increase oil production and reduce the weight of C.sub.4+ hydrocarbons lost in the associated gas.

摘要： Improved processes for treating gas streams containing hydrogen sulfide and carbon dioxide, particularly natural gas streams. The processes rely on the availability of a membrane that maintains high hydrogen sulfide/methane selectivity and adequate hydrogen sulfide/carbon dioxide selectivity when measured with multicomponent gas mixtures at high pressure. The processes have three steps: an acid gas removal step, to remove both hydrogen sulfide and carbon dioxide from the primary gas stream; a membrane fractionation step, to separate hydrogen sulfide from carbon dioxide and create a highly hydrogen-sulfide-concentrated fraction; and a sulfur-fixing step.

摘要： A process for hydroprocessing a fluid stream containing at least hydrogen and hydrocarbons. The process uses a hydrocarbon-selective membrane to reduce the concentration of hydrocarbons and contaminants in the hydrogen stream recycled to the hydroprocessing reactor. The membrane can operate in the presence of hydrogen sulfide. The process also provides the opportunity for increased NGL recovery from the hydrocarbon-enriched membrane permeate stream.

摘要： A process for separating two low-boiling components of a gas-phase mixture. The invention involves three separation steps: condensation, flash evaporation and membrane separation. The steps are integrated together in such a way as to provide a good separation between the components, and to avoid creation of secondary streams that need additional treatment. The invention is particularly useful for separation of low molecular weight organic compounds from other gases.

摘要： An improved process and process train for catalytic reforming of hydrocarbons. In its most simple form, the invention includes four unit operations or steps: the reforming itself usually carried out in a series of reactors; one or more steps to separate the reformate liquid product from overhead gases, predominantly C1-C6 hydrocarbons and hydrogen; one or more treatment steps to recover hydrogen from the overhead gases, and one or more treatment steps, including a membrane gas separation step, for the waste gas from the hydrogen recovery step. The process provides improved recovery of hydrogen and LPG, and reduces the amount of gas sent to the fuel line.
