Merox (original) (raw)
Merox is een afkorting voor mercaptaan oxidatie. Het is een proces dat raffinaderijen toepassen om mercaptanen uit processtromen te verwijderen. Bijvoorbeeld: * overhead van atmosferische destillatie (C2, C3 & C4 fracties) * kerosine * fluid catalytic cracking (FCC of catcracker producten) Wereldwijd staan zo'n 1700 Merox units opgesteld.

| dbo:abstract | 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 requires an alkaline environment which, in some process versions, is provided by an aqueous solution of sodium hydroxide (NaOH), a strong base, commonly referred to as caustic. In other versions of the process, the alkalinity is provided by ammonia, which is a weak base. The catalyst in some versions of the process is a water-soluble liquid. In other versions, the catalyst is impregnated onto charcoal granules. Processes within oil refineries or natural gas processing plants that remove mercaptans and/or hydrogen sulfide (H2S) are commonly referred to as sweetening processes because they results in products which no longer have the sour, foul odors of mercaptans and hydrogen sulfide. The liquid hydrocarbon disulfides may remain in the sweetened products. These may be used as part of the refinery or natural gas processing plant fuel, or they may be processed further. When dealing with kerosene, the Merox process is usually more economical than using a catalytic hydrodesulfurization process for much the same purpose. It is rarely (if ever) required to reduce the sulphur content of a straight-run kerosene to meet the 3000 ppm sulphur specification of jet fuel, because very few crude oils have a kerosene cut with a higher content of sulphur than this limit.

En effet, le soufre et ses dérivés sont très corrosifs et très toxiques. Ils corrodent tous les métaux, donc tous les circuits d'alimentation d'un moteur à combustion interne ou d'un moteur à réaction. Ce procédé n'est utilisé que pour des produits pétroliers contenant de faibles quantités de soufre (soufre mercaptan). Pour éliminer celui-ci, on le transforme en disulfure. Ce dernier reste néanmoins dans la coupe pétrolière. Il existe un procédé Mérox extractif qui élimine ce disulfure. C'est un procédé utilisé généralement pour la coupe kérosène servant à la fabrication du Jet Fuel (Jet A1). * Portail de la chimie * Portail des énergies fossiles (fr) Merox is een afkorting voor mercaptaan oxidatie.
