Title
(EN) APPARATUS AND METHOD FOR REMOVING MERCURY FROM A GAS
Abstract
(EN)
THE PRESENT INVENTION PROVIDES A METHOD AND APPARATUS FOR REMOVING MERCURY FROM GASES SUCH AS THOSE DISCHARGED FROM ROASTERS AND OTHER HEAT PRODUCING SYSTEMS. IN EMBODIMENTS THE METHOD COMPRISES REACTING THE MERCURY WITH DISSOLVED MOLECULAR CHLORINE, AND MAY ALSO COMPRISE REACTING THE MERCURY WITH MERCURIC CHLORIDE TO YIELD MERCUROUS CHLORIDE. THE MERCUROUS CHLORIDE MAY BE REMOVED BY PRECIPITATION. THERE ARE ALSO DISCLOSED APPARATUSES FOR IMPLEMENTING THE METHOD.
