Process for manufacturing hydrogen chloride

摘要

Hydrogen chloride (HCl) production is carried out in 2 stages, comprising (1) reacting chlorine (Cl2) with steam to a mixture of HCl and oxygen (O2) in an endothermic process, with heat supply; and (2) adding a reducing agent to convert unreacted Cl2 from stage 1 to HCl in an exothermic reaction and to bind O2 formed in stage 1. An independent claim is also included for the plant used.
