ABSTRACT
This chapter integrates the thermal chlorination process with chlorine production process obtained by catalytic air oxidation of recovered hydrogen chloride (HCl) of the thermal process. Different flow sheet alternatives for chloromethanes manufacturing were considered and the best alternative obtained was the one involving absorption of HCl from vapor stream in chloromethanes mixture integrated with process of production of chlorine from recovered anhydrous HCl. The chloromethanes synthesis case study was considered due to scope involved in applying green engineering principles such as waste minimization, reuse, and to show the impact of the modified process on the economics. Green engineering broadly encompasses design, commercialization, and use of products and processes that are feasible and economical while minimizing risk to human health, environment and elimination, and reduction or reuse of wastes at source by effective utilization of material and energy.
