摘要： A membrane separation assembly that includes an integrated filter element and at least one membrane module housed within a first vessel and a second vessel containing at least one membrane module, which is stacked or aligned adjacent to the first vessel. The first vessel is configured to allow liquids to be trapped and removed from the assembly, and gases to flow to and through the membrane modules of the first vessel and the membrane modules of the second vessel, which are ultimately withdrawn from the assembly. The assembly is useful in the conditioning of fuel gas to separate methane from C2+ hydrocarbons.

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 uses glassy polymeric membranes that are preferentially permeable to methane over C2+ hydrocarbons to produce a partially purified methane stream. Conditioned fuel gas has lower heating value, higher methane number, and will result in greatly reduced emissions from the engines.

摘要： A process for treating natural gas or other methane-rich gas to remove excess nitrogen. The invention relies on two-stage membrane separation, using methane-selective membranes for the first stage and nitrogen-selective membranes for the second stage. The process enables the nitrogen content of the gas to be substantially reduced, without requiring the membranes to be operated at very low temperatures.

摘要： Improved membranes and improved membrane processes for treating gas streams containing hydrogen sulfide, carbon dioxide, water vapor and methane, particularly natural gas streams. The processes rely on the availability of two membrane types, one of which has a hydrogen sulfide/methane selectivity of at least about 40 when measured with multicomponent gas mixtures at high pressure. Based on the different permeation properties of the two membrane types, optimized separation processes can be designed.
