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 SO 2 removal system, introducing the SO 2 rich stream from the SO 2 removal system to a CO 2 removal system, and introducing an enriched SO 2 stream back to the Claus unit. The SO 2 removal system can include one or more SO 2 selective membranes. The CO 2 removal system can include one or more CO 2 selective membranes.

摘要： A process for separating components of a gas mixture using gas-separation copolymer membranes. These membranes use a selective layer made from copolymers of an amorphous perfluorinated dioxolane and a fluorovinyl monomer. 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 process for treating an effluent gas stream arising from a manufacturing operation that produces an olefin or a non-polymeric olefin derivative. The process involves cooling and condensing the effluent gas stream (104), which comprises an olefin, a paraffin, and a third gas, to produce a liquid condensate (108) and an uncondensed (residual) gas stream (114). Both streams are then passed through membrane separation steps (109; 115). The membrane separation of the uncondensed gas stream (114) results in an olefin-enriched stream (117) and an olefin-depleted stream (118). The olefin-enriched stream is recirculated within the process prior to the condensation step. The membrane separation of the condensate (108) also results in an olefin-enriched stream (111), which may be recycled for use within the manufacturing operation, and an olefin-depleted stream (113), which may be purged from the process.

摘要： The invention is a pervaporation process and pervaporation equipment, using a series of membrane modules (102 to 105, 204), and including inter-module reheating of the feed solution under treatment. The inter-module heating is achieved within the tube or vessel (101, 201) in which the modules are housed, thereby avoiding the need to repeatedly extract the feed solution from the membrane module train.

摘要： A membrane process for separating chlorine from chlorine-containing gas streams (1) is disclosed. The process employs a permselective membrane (2) that is selective to chlorine and is stable in the long-term presence of chlorine. The process can be used to treat tail-gas from chlor-alkali plants, for example.
