Meet downstream unit feedstock requirements

An LPG Extraction Merox Unit is designed to remove H2S, COS and Mercaptans from the LPG required when further processing of C3 and C4 olefins in alkylation, polymerization or petrochemical synthesis is required. The capital-efficient Extractor Plus design is typically used in this service.

The Extractor Plus design incorporates caustic pre-treatment, mercaptan extraction and post-treatment into a single vessel, thereby offering a low capital cost alternative to other extraction processes. Typical product mercaptan levels can be controlled to less than 5 wppm.
