Temperature control system

Abstract

The temperature control system of the present invention is a temperature control system for recovering reaction heat inside a reactor in which an exothermic reaction takes place, thereby controlling a temperature inside the reactor. The temperature control system is provided with a coolant drum in which a liquid coolant is accommodated in a vapor-liquid equilibrium state, a heat removing unit which is disposed on the reactor to internally circulate the liquid coolant supplied from the coolant drum, a temperature determining unit which determines a temperature inside the reactor, and a pressure controller which controls pressure inside the coolant drum. The pressure controller controls the pressure inside the coolant drum based on a difference between an actual temperature inside the reactor determined by the temperature determining unit and a preset temperature value inside the reactor, thereby controlling the temperature of the liquid coolant inside the coolant drum.

1 . A temperature control system for recovering reaction heat inside a reactor in which an exothermic reaction takes place, thereby controlling a temperature inside the reactor, the temperature control system comprising:
 a coolant drum in which a liquid coolant is accommodated in a vapor-liquid equilibrium state;   a heat removing unit which is disposed on the reactor to internally circulate the liquid coolant supplied from the coolant drum;   a temperature determining unit which determines a temperature inside the reactor; and   a pressure controller which controls pressure inside the coolant drum, wherein the pressure controller controls the pressure inside the coolant drum based on a difference between an actual temperature inside the reactor determined by the temperature determining unit and a preset temperature value inside the reactor, thereby controlling the temperature of the liquid coolant inside the coolant drum.
