MULTIPLE REACTOR CHEMICAL PRODUCTION SYSTEM

摘要

The present invention is a multiple reaction set for the production of chemicals by equilibrium limited reactions utilizing plate-type or extended surface heat exchangers. The heat exchangers effectively cool the reaction products in order to condense the methanol contained within the reaction products for separation, and also to warm incoming feed reactants prior to entrance of the reactants into a reactor utilized for the production of methanol. The various reactors, heat exchangers, and separators can be formed as separated zones within the enclosed vessels, thereby eliminating the need for separately constructed reactors, heat exchangers, and separators. Multi-stream plate-type of extended surface heat exchangers can be utilized to allow efficient cooling and methanol separation. The multiple reaction set can also be used for the recovery of methanol from a waste or purge gas stream utilizing multiple reactors, multiple plate-type or extended surface heat exchangers and multiple separators as a substitute for or in conjunction with a conventional methanol synthesis loop.
