Double stages coal gasifier cold plant description

Double gasifier gas is divided into the upper gas and the lower gas. Upper gas temperature is 90-150°C, after the removal of heavy tar and dust by electric tar catcher, it goes into the indirect cooler and it is cooled to 35-45°C for electric light oil catcher. Lower gas temperature is about 450-550°C, it goes into the cyclone dust collector first, after that it enters the waste heat exchanger, to cool the gas and recover the heat from it, gas temperature is reduced to 200-230°C before entering the wind cooling system, the temperature is dropped to 65-80°C after the wind cooling process. Through indirect cooler, lower gas is cooled to 35-45°C by circulating cooling water. After all the process, upper gas and lower gas go to the electric light oil catcher II for secondary oil and dust removal. The purified gas is then pressurized and transport to user through pipes.
