THIOLEX^SM
FIBER-FILM™ Contactor caustic extraction of hydrogen sulfide, carbonyl sulfide, carbon dioxide and mercaptans from gases, LPG and naphthas.

REGEN^SM with Gravity Separation
Catalytic oxidation of THIOLEX^SM mercaptide caustic followed by gravity separation of disulfide oil in order to reuse the caustic in mercaptan extraction systems.

REGEN^SM with Solvent Wash
Catalytic oxidation of THIOLEX^SM mercaptide caustic followed by solvent washing in a FIBER-FILM™ Contactor for complete disulfide oil removal in order to reuse the caustic in mercaptan extraction systems. Catalytic caustic oxidation know-how in combination with FIBER-FILM™ Contactor extraction promotes safe, economical regeneration of spent caustic in this application of the REGEN^SM system
