Merox is an acronym for Mercaptan Oxidation.
It is a proprietary catalytic chemical process developed by UOP used inoil refineries and natural gas processing plants to remove mercaptans from LPG, propane, butanes, light naphthas, kerosene and jet fuel by converting them to liquid hydrocarbon disulfides.
The Merox™ process is a technology developed and licensed by UOP for the purpose of reducing sulfur or sweetening sulfur compounds in hydrocarbon streams. The process is one of the most widely applied technologies in the world for this service. While found in most petroleum refining facilities, the Merox process is also applicable for other facilities processing sulfur-containing hydrocarbons.
MEROX process (acronym of Mercaptan Oxidation), UOP licensed, consists in catalytic oxidation of mercaptants that are present in hydrocarbons as consequence of petrol or natural gas refinement activities. MEROX process allows to remove mercaptans from GPL, propane, butane, naphtha, kerosene etc. by turning them into disulfides according to the following reaction:
4 RSH + O2 = 2RSSR + 2H2O
