During the operation of the supporting gas-water separation device of the coal-to-natural gas project,there are problems such as the difficulty of discharging the sewage pipeline of the gas-water storage tank,the blockage of the pipe bundle of the waste heat recovery device,and the high content of heavy aromatic hydrocarbon water in the delivery.In view of the problems that arose,we carefully studied and analyzed them,formulated and implemented effective measures,e.g.improving gas-water storage tank,adding gas-water separation device before waste heat recovery,and adding two(2)sets of heavy aromatics knockout tank.It ensures the safe,stable and long-term operation of the gas-water separation device.
