Merox is an acronym for mercaptan oxidation. It is a proprietary catalytic chemical process developed by UOP used in oil 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 can be applied in a petroleum refinery to treat Kerosene, Jet fuel, naphtha, LPG, or natural gas for order improvement, sulfur removal, meet product specifications and help the oxidation inhibitors to prevent gum formation in the gasoline.

UOP Merox WS-2 catalyst is specially formulated to selectively oxidize mercaptans in liquid-liquid Merox LPG extraction units. It is available in a variety of packaging options to fit the needs of any installation.

The UOP Merox process, first commercialized 60 years ago, extracts low molecular weight mercaptans from gas and LPG streams. UOP has continued to improve the process and manufactures highly active and selective catalysts to help refiners reduce capital investment and improve operability.

UOP’s Merox™ process technology extracts or converts low molecular weight mercaptans from refinery product streams using a regenerable caustic solution. The Merox portfolio includes technologies that will treat gas, LPG, naphtha, kerosene and …

Jun 22, 2018 · Products: Essentially mercaptan sulfur-free, i.e., less than 5 ppmw, and concomitant reduced total sulfur content when treated by Merox extraction technique. Merox units are designed in several flow configurations, depending on …

Merox Extraction - A two stage process (caustic + oxidation) used to clean lighter molecular weight hydrocarbons such as LPG's (Liquefied Petroleum Gases), pentanes, and NGL's (Natural Gas Condensates). Merox extraction processes begin with H2S removal. Often this is done upstream with an amine treatment unit.

Merox is an acronym for ‘mercaptan oxidation’, a well-established process to remove mercaptans from refined products such as kerosene and jet fuel, to meet the regulatory requirements for reduced sulfur levels in aviation fuel.

The MEROX process licensed by M/S Universal Oil Products Co., (UOP), USA, is for the chemical treatment of LPG, gasoline and distillates to remove mercaptans into disulfides. The removal of mercaptans may be either partial or full.

Aug 20, 2020 · The Universal Oil Products (UOP) company developed the mercaptan oxidation (MEROX) technology by 1959 by the sweetening of crude oil distillates such as liquefied petroleum gas (LPG), naphthas, jet fuel, and gasoline, …
