摘要： Methods and systems for recovering sulfur dioxide from a Claus unit process emissions stream are provided. The method comprises the steps of generating a process emissions stream from a thermal oxidizer or other combustion device, introducing the emissions stream to an SO2 removal system, introducing the SO2 rich stream from the SO2 removal system to a CO2 removal system, and introducing an enriched SO2 stream back to the Claus unit. The SO2 removal system can include one or more SO2 selective membranes. The CO2 removal system can include one or more CO2 selective membranes.

摘要： Methods are provided for reducing the quantity of acid gas reinjected into a reservoir by partial CO2 removal processes. The methods include acid gas removal, acid gas enrichment, generation of a CO2 rich stream and an H2S rich stream, and reinjection of the H2S rich stream into the reservoir. The acid gas enrichment can be performed by a solvent-based acid gas enrichment unit, a membrane-based acid gas enrichment unit, or a combination of a solvent-based acid gas enrichment unit a and membrane-based acid gas enrichment unit. The system includes an acid gas removal unit, one or more acid gas enrichment units, and an acid gas reinjection compressor. The acid gas enrichment unit can be a solvent-based acid gas enrichment unit, a membrane-based acid gas enrichment unit, or a solvent-based acid gas enrichment unit and a membrane-based acid gas enrichment unit.

摘要： The present invention relates to a process for concurrently removing CO2 and SO2 from flue gas produced by a combustion process, comprising: (a) performing a combustion process by combusting a fuel and air in a combustion apparatus, thereby creating an exhaust stream comprising CO2 and SO2; (b) compressing the exhaust stream in a first compression step, thereby producing a first compressed gas stream; (c) providing a first membrane having a feed side and a permeate side, and being selectively permeable to CO2 and SO2 over nitrogen and to CO2 and SO2 over oxygen; (d) passing at least a portion of the first compressed gas stream across the feed side; (e) withdrawing from the feed side a CO2- and SO2-depleted residue stream; (f) withdrawing from the permeate side at a lower pressure than the first compressed gas stream, a first permeate stream enriched in CO2 and SO2; (g) passing the first permeate stream to a separation process that produces a stream enriched in CO2 and a stream enriched in SO2.

摘要： Sweep-based gas separation processes for reducing carbon dioxide emissions from gas-fired power plants. The invention involves at least two compression steps, a combustion step, a carbon dioxide capture step, a power generate step, and a sweep-based membrane separation step. One of the compression steps is used to produce a low-pressure, low-temperature compressed stream that is sent for treatment in the carbon dioxide capture step, thereby avoiding the need to expend large amounts of energy to cool an otherwise hot compressed stream from a typical compressor that produces a high-pressure stream, usually at 20-30 bar or more.

摘要： Disclosed herein is a process for separating components of a gas mixture using gas-separation copolymer membranes. These membranes use a selective layer made from copolymers of perfluorodioxolane monomers. The resulting membranes have superior selectivity performance for gas pairs of interest while maintaining fast gas permeance compared to membranes prepared using conventional perfluoropolymers, such as Teflon® AF, Hyflon® AD, and Cytop®.

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： Gas separation processes are provided for separating dehydrogenation reaction products from a raw gas stream to recover hydrocarbons, specifically olefins, such as propylene and iso-butene, as well as unreacted feedstock. The processes employ a sequence of partial condensation steps, interspersed with membrane separation steps to raise the hydrocarbon dewpoint of the uncondensed gas, thereby avoiding the use of low-temperature or cryogenic conditions.

摘要： A gas separation process for treating a gas stream containing vapors of condensable components. The process includes two membrane separation steps, the second step using membranes of lower selectivity than the first step. Advantageously, the first membrane separation step may be carried out outside the pressure-ratio-limited region and the second membrane separation step may be carried out within the pressure-ratio-limited region. The second residue stream is a desired product of the process, and the process is particularly useful for applications where the target concentration of component A in this product is low, such as below 1-2 vol %.
