发明名称 Method and device for exploiting heat resulting from the production of 1,2-dichloroethane
摘要 <p>The invention relates to a method and a device for the optimal use of reaction heat resulting from the production of 1,2-dichloroethane from ethene and chlorine. The aim of the invention is achieved by extracting reaction heat liberated during the reaction of chlorine with ethene and the reaction heat contained in 1,2-dichloroethane. Extraction of said reaction heat from the reaction chamber occurs using at least one part of gaseous 1,2-dichloroethane (latent heat) and at least one part of liquid 1,2-dichloroethane (feelable heat) removed from the reaction chamber. Said reaction heat is used to heat two fractioning columns in order to purify 1,2-dichloroethane of impurities having a boiling point higher than 1,2-dichloroethane.</p>
