Production method using permeation of at least two gaseous fluxes from a gaseous mixture, and a production installation for implementing this method

摘要

This method permits the production of at least two gaseous fluxes enriched in a permeable component from a gaseous mixture wherein the fluxes are considerably different, compared to the gaseous mixture. A first permeation unit (20) is supplied by the gaseous mixture feed. A second permeation unit (22) is supplied by the non-permeate produced by the first unit (20). The permeate produced by the second unit (22) which forms a first enriched flux is then sent to the third permeation unit (24) to form a second enriched flux.
