PERCO

PERCO is a gas sweetening catalyst used to convert Mercaptan (RSH) sulfur compounds in both liquid and gaseous hydrocarbons to non-corrosive and odorless disulfides. PERCO eliminates Mercaptan sulfur induced corrosivity and improves odor on all stocks. The catalyst an be used to treat methane, ethane, propane, butane, natural gasoline, straight run gasoline, kerosene and mixtures thereof. It offers low pressure-drop, long bed life, simplistic design and operates over a broad range of flow rates and temperatures.
