Oil Refineries

Crude oil which is extracted from oil wells all over the world contains complex compounds of sulphur and other odor causing organic chemicals in varied concentrations depending on the geography of a particular region. Refineries which process Crude oil to remove fractions of volatile hydrocarbons have to periodically remove these sulphur compounds as it hinders the production process by clogging pipelines.This situation also puts the workers life at risk due to emission of Hydrogen Sulphide gas and formation of Pyrophoric Iron Sulphides. Sodium/ Potassium permanganate is used by the Oil Refiners to eliminate Pyrophoric Iron Sulphide, Odorous Sulphide compounds and Mercaptans due to its strong oxidizing power, thereby, generating harmless by-products.
