A method for removing Trace amount of Mercury in a Supply of natural gas. (Divisional Application 556 - 2015)

摘要

p The Invention discloses a method for removing Trace amount of Mercury in a Supply of Natural Gas, which comprises: providing a feed gas containing gases, acids,Water vapor and a First concentration of Volatile Mercury; contacting the feed gas with an Absorption solution in the absorberThe solution comprises a First Amine Absorption and Poor complexing AgentWhere the solution Absorption and acid gases simultaneously removes mercury from gas power generating a solution of mercury containing Rich Amine acids and gases and a StreamYou treated gas containing water vapor and a low concentration of acid Gas and a Second concentration of Mercury,And where the second Mercury concentration is less than 50% of the initial concentration of Mercury; contacting the gas Stream with a solution in a glycol dehydrator,Glycol Solution which contains a Second complexing Agent PEAR that the glycol Solution simultaneously remove Mercury and water vapor from the gas Stream TreatyGenerating a Volatile Rich glycol containing no Mercury and a gas Stream with a reduced concentration of Dehydrated Water and a Third concentration of Mercury,Where the Third Mercury concentration is less than 50% of the second concentration of Mercury. / p
