Treating AMINEX and THIOLEX Processes by Merichem Chemicals & Refinery Services

Application: AMINEX and THIOLEX systems extract COS and H2S from gases with amine or caustic solution using FIBER-FILM Contactor technology.

Description: In an AMINEX system, the amine phase flows along the fibers of the FIBER-FILM Contactor as it preferentially wets the fibers. The gas phase flows through the Contactor parallel to the amine-wetted fibers as the COS and H2S is extracted into the amine. The two phases disengage in the separator vessel with the rich amine flowing to the amine regeneration unit and the treated gas flowing to its final use. Similarly, a THIOLEX system employs the same process utilizing caustic and caustic/amine solutions to preferentially wet the fibers as the COS and H2S is extracted into the caustic phase. The rich caustic flows to sulfidic caustic storage and the treated gas flows to its final use. Competitive advantages: FIBER-FILM Contactor technology requires smaller processing vessels thus saving valuable plant space and reducing capital expenditures.
