摘要： A process and equipment for treating natural gas produced by a well that has recently been stimulated, and that contains an undesirably high concentration of the fracturing gas used to stimulate the well. The process involves treating the gas by membrane separation, and provides for control of treatment parameters to compensate for the changing concentration of fracturing gas in the produced gas, as well as changes in gas flow rate.

摘要： A process and system for recovering natural gas liquids (NGL) using a combination of J-T cooling and membrane separation. The process involves compressing, separating, and cooling a flare gas stream comprising at least methane and C3+ hydrocarbons prior to being introduced to a J-T valve. The cooled stream exiting the J-T valve is further separated, producing a NGL product stream and an uncondensed gas stream. The uncondensed gas stream is directed to a membrane separation step, which results in a C3+ hydrocarbon enriched stream and a C3+ hydrocarbon depleted stream. The C3+ hydrocarbon enriched stream may be recycled back to the process to recover more NGL.

摘要： Disclosed herein is a process for conditioning natural gas containing C3+ hydrocarbons, so that it can be used as combustion fuel to run gas-powered equipment, including gas engines and turbine-driven compressors, in the gas field or the gas processing plant. The claimed process use glassy polymeric membranes that are preferentially permeable to methane over C2+ hydrocarbons to produce a partially purified methane stream. The process operates at a stage cut of at least about 5%.

摘要： A method for generating electric power, such as at, or close to, natural gas fields. The method includes conditioning natural gas containing C.sub.3+ hydrocarbons and/or acid gas by means of a membrane separation step. This step creates a leaner, sweeter, drier gas, which is then used as combustion fuel to run a turbine, which is in turn used for power generation.

摘要： A process train for treating a gas stream containing methane, nitrogen, and at least one of water vapor, acid gas, C.sub.3+ hydrocarbons and aromatic hydrocarbons, the gas stream typically, but not necessarily, being natural gas. The treatment train includes separation of methane from nitrogen by means of membranes that preferentially permeate methane and reject nitrogen. Preferred processes include both a dehydration step and an NGL removal step to treat the gas before it passes to the methane/nitrogen membrane separation step. The process train can also include additional steps, such as an acid gas removal step, or a cryogenic methane/nitrogen separation step.
