Cooling system for holding a chemical reaction at a required temperature - has three heat exchangers connected to cooling pump

摘要

The chemical reaction occurs in the reactor (R1) which is held at the required reaction temperature either by heating or by cooling. The reactor can be connected to any one of three heat exchanges (W1-W3) which are held at temperatures of 180 deg. C, 40 deg. C and -15 deg. C respectively. The three heat exchanges are connected in parallel to a cooling circuit, in which a cooling liquid is circulated by a pump (P1) and held at the required pressure by nitrogen which is supplied through a pressure control valve (PC). The high temperature heat exchanger (W1) is supplied with high pressure steam, the medium temperature heat exchanger (W2) is supplied with cooling water, and the low temperature heat exchanger is supplied with brine. USE/ADVANTAGE - Maintaining a chemical reaction at the required temperature between -20 deg. C and 200 deg. C.
