Temperaturregelverfahren für Reaktionen

摘要

A method for controlling reaction temperature for a reaction vessel (1) used for conducting an exothermic reaction is disclosed which comprises employing two or more independent flow channels (2A,2B) and feeding two or more coolants having different temperatures to the independent flow channels (2A,2B) according to the quantity of heat to be removed. By use of this method, not only energy-efficient coolant utilization and improved reaction control can be attained, but a high production efficiency and production flexibility can be achieved. This method also has advantages, over the method for using coolant L throughout a reaction, that since the coolant is used only in the case of necessity, a small refrigerating apparatus is sufficient and a reduction in energy cost is attained. This method is more effective when applied to a reaction vessel (1) employing a temperature control element (8) having a high efficiency of heat transfer.
