Claim Text:
1. A temperature control system for controlling a temperature inside a reactor in which an exothermic reaction takes place by recovering reaction heat in the reactor, the temperature control system comprising: a lower heat removing unit which is disposed at the bottom of the reactor and through which a liquid coolant is flowed; and an upper heat removing unit which is disposed in the reactor further above from the lower heat removing unit and through which the liquid coolant is flowed, wherein the lower heat removing unit is supplied with the liquid coolant which is adjusted for temperature by a first temperature adjustment unit, and the upper heat removing unit is supplied with the liquid coolant which is adjusted for temperature by a second temperature adjustment unit different from the first temperature adjustment unit, wherein the system further comprises: a reaction heat temperature determination unit which determines a temperature inside the bottom of the reactor, wherein the first temperature adjustment unit is controlled on the basis of a determination result of the reaction heat temperature determination unit, and wherein the first temperature adjustment unit is provided with a coolant drum in which a liquid coolant is accommodated in a gas-liquid equilibrium state; a pressure control unit which controls a pressure inside the coolant drum, wherein the pressure control unit controls the pressure inside the coolant drum on the basis of deviation of an actual temperature inside the bottom of the reactor determined by the reaction heat temperature determination unit from a temperature set value inside the bottom, thereby controlling a temperature of the liquid coolant inside the coolant drum, and wherein the coolant drum is provided with a coolant feeding unit which feeds a liquid coolant thereinto, the coolant feeding unit is disposed inside a gas phase portion of the coolant drum, and a dispersing unit which disperses a liquid coolant to the gas phase portion is formed at the coolant feeding unit.
