PROCESS AND APPARATUS FOR PREPARING HYDROGEN CHLORIDE

摘要

Process for preparing hydrogen chloride, in which chlorine reacts with water vapor in an endothermic reaction with heat being supplied in a first process step to give a mixture of hydrogen chloride and oxygen and, in a second process step, chlorine which has not been reacted in the first process step is converted into hydrogen chloride in an exothermic reaction by addition of a reducing agent and oxygen formed in the first process step is bound by means of the reducing agent, and an apparatus for this process.
