Remove RSH, H2S, CO2 and COS with THIOLEX

Featuring our proprietary FIBER FILM® Contactor, Merichem’s THIOLEX technology uses a caustic solution to remove mercaptan compounds and other impurities. It allows for total sulfur reduction in hydrocarbon streams to meet client specifications while delivering greater design and operational flexibility, improving sales and profits.

About THIOLEX

H2S Removal with LO-CAT®

Merichem’s patented liquid redox system uses a chelated iron solution to convert dangerous H2S into innocuous, elemental sulfur. Chemical-based, it offers greater reliability and flexibility than biological treatment—with no liquid waste streams or waste products.

About LO-CAT

Regenerate Spent Caustic Product with REGEN®

Merichem’s REGEN® technology reduces caustic consumption through the regeneration of the caustic solution. With applications in all caustic streams used in mercaptan treating processes, it allows mercaptides to be oxidized into disulfide oil (DSO), recovering sodium hydroxide and minimizing virgin caustic consumption.

About REGEN
