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 cool the reaction products to condense methanol within the reaction products for separation, and to warm incoming feed reactants prior to entrance of the reactants into a reactor utilized for methanol production. The various reactors, heat exchangers, and separators can be formed as separated zones within 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.
