Abstract ：The application of hollow fiber membrane to separation of SF6 from SF6 mixture gas is a new separation method, and it has many advantages over tradition separation technology. Membrane module structure, separation principle and related product performance are introduced. Taking hollow fiber membrane for example, the typical separation process is induced\using membrane module, including singe-stage membrane separation process, more-stage membrane separation process. The composition of product gas and permeation gas as well as the parameters such as methane recovery rate and purity are obtained by system simulation.
