ABSTRACT:
The invention relates to an apparatus for the production of vinyl chloride by starting from dichloroethane, wherein dichloroethane is heated, without being vaporized, in the convective section of an oven, it is then vaporized by indirect heat exchange with air or another fluid, which is heated in its turn by exploiting the heat of the cracking products leaving that oven, and containing monomer vinyl chloride. Dichloroethane, as vapor, is introduced into the radiant section of the oven, wherein it undergoes the cracking and forms vinyl chloride and, if it has been used, a portion of the air heated by the heat of the cracking products can be delivered to the oven burners. The system for carrying out the process is illustrated in FIGS. from 1 to 3, and to them reference is made.
