Publication number: 20130306299Abstract: 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.Type: ApplicationFiled: January 17, 2012Publication date: November 21, 2013Applicants: JAPAN OIL, GAS AND METALS NATIONAL CORPORATION, INPEX CORPORATION, NIPPON STEEL & SUMIKIN ENGINEERING CO., LTD., JAPAN PETROLEUM EXPLORATION CO., LTD., COSMO OIL CO., LTD., JX NIPPON OIL & ENERGY CORPORATIONInventors: Kentarou Morita, Yuzuru Kato
