Siloxane removal with gas permeation membranes
Conventional methods of siloxane removal include condensation and sorption. The AVT.CVT has identified gas permeation as a potential new method and is currently testing the applicability of new membrane materials. Several membrane materials were found to be suitable. First field trials with landfill gas showed that the tested membranes are relatively selective for siloxanes. Currently, a membrane module of 1m² is built with which the applicability of different operating modes (3-end or 4-end) at different temperatures will be tested. The technology is interesting for other siloxane-related applications, such as mechanical-biological waste treatment (MBT) or the protection of expensive catalysts used to purify engine exhaust gases.
