Abstract

Highly exothermic continuous chemical reactions such as the methanization of carbon oxides are cooled by indirect heat exchange with a liquid coolant such as water, thereby converting at least some of the liquid to a vapor such as steam. When the reaction temperature, because of operational difficulties or the like, exceeds the design temperature of the reaction, said vapor such as steam is passed into the reaction chamber. In this way, the reaction stream is cooled as well as diluted; in addition, since the vapor is preferably selected to be a reaction product, the extent and rate of the exothermic reaction are diminished.
