Abstract

Post-combustion chemical decarbonization process is one of the important technology options for the low-carbon development of natural gas power plants. In this paper, the operating parameters of CO2 capture using new ternary amines are studied in a 1800t/y demonstration plant at Beijing Gaojing Thermal Power Station. The influence of main operating parameters on the CO2 capture efficiency and specific heat consumption is investigated. The test results show that the optimum operating conditions are flue gas flow rate (Vfg) 3000Nm3/h, flue gas temperature (Tfg) 40℃, reboiler steam flow rate (Qreb) 367kg/h, desorber operating pressure (Pdes) 10kPa, solvent circulating flow rate (fsol) 4.0m3/h. Under optimum operating conditions, the average CO2 capture efficiency capture is 90.6%, and the specific heat consumption is 3.29 GJ/tCO2.
