In order to deeply understand the gas condensation process of gas unit,a gas condensation test bench is constructed on site.Through the field simulation test,the cooling effect of plate heat exchanger,spray packed tower heat exchanger and the combination of two kinds of heat exchanger on the flue gas is studied,and the condensed water of the flue gas is analyzed.The results show that under the combined condition of plate heat exchanger and spray heat exchanger,when the total flow of cooling water is constant,the overall cooling effect of plate heat exchanger and spray packed tower heat exchanger is basically the same.The dew point temperature of flue gas obtained by experiment is close to the theoretical calculation result.Flue gas condensate water belongs to neutral water,the content of calcium and magnesium ions is low,but NH4+content is high.
