PROCESS FOR PRODUCING CHLORINE DIOXIDE USING WASTE GLYCEROL FROM A BIODIESEL PLANT

摘要

A process for chlorine dioxide production uses waste glycerol from biodiesel plants as a reducing agent. This untreated waste stream may contain other reducing agents such as sodium chloride and methanol which were found to enhance the chlorine dioxide production. Other chemicals present in this waste stream did not affect the operation of the chlorine dioxide generator. Substituting the waste glycerol for methanol or other reducing agents helps kraft pulp mills in reducing the cost of producing chlorine dioxide while providing a use for the untreated waste glycerol stream.
