Étude expérimentale et simulation de procédés hybrides intégrant des membranes zéolites et polymères pour la purification d’hydrocarbures gazeux biosourcés par perméation de vapeurs

Abstract : This work focused on the interest of using a zeolite composite membrane (CHA SSZ-13) accessible on a commercial scale through the membrane technology of gas and vapor permeation. The applicability of this separation technology has mainly focused on the recovery of methane, propane and isobutene from fluxes produced at industrial scales by sustainable processes. The development of an experimental lab scale pilot for gas and vapor permeation data measurements is detailed. Based on experimental permeation measurements carried out with the zeolite membrane of the study, a first case of practical application was to simulate the separation performance of a hybrid process associating a zeolite membrane module with a cryogenic condensation from an industrial specification for the recovery of isobutene. The hybrid process studied is always more efficient than the only cryogenic condensation process taken as reference in terms of purity of the condensed product obtained and energy consumption. A chart was generated to locate the simulated separation performance based on the desired isobutene recovery objective. A second theoretical case of propane recovery from nitrogen purging vents with hybrid membrane cryogenic separation process was studied. This study presented a chart of the membrane separation performance of propane over nitrogen according to data from the open literature. The most nitrogen- and propane-selective membrane (CHA SSZ-13 and PEBAX 2533 respectively) was then selected and used in order to simulate hybrid processes where separation performances were compared to a baseline cryogenic standalone process. For low propane contents in the nitrogen feed mixture, it was found that the most efficient process (energy need and quality of the condensed product) involved a PEBAX 2533 polymer membrane module with a vacuum system for the permeate.
