Caustic Treating

ECOMERICAT™
Oxidation of mercaptans in gasoline/naphtha and subsequent neutralization of phenolic caustic using carbon dioxide to reduce phenolic compounds in the neutralized brine.

MERICON™
Onsite oxidation or neutralization of sulfidic and organic spent caustics to reduce BOD, COD and organics before transfer to waste water treating facilities.

REGEN® with Gravity Separation
Catalytic oxidation of mercaptide caustic followed by gravity separation of disulfide oil to permit reuse of the caustic in mercaptan extraction stages without significant DSO back extraction.



REGEN® with Solvent Wash
Catalytic oxidation of mercaptide caustic followed by solvent washing in a FIBER FILM® Contactor for complete disulfide oil removal in order to reuse the caustic in total sulfur reduction stages without significant DSO back extraction.

REGEN® ULS
Catalytic oxidation of mercaptide caustic and near-complete DSO removal from the oxidized caustic which in turn allows manufacture of a
