Additional Generator Set for Methanation Unit Waste Heat Recovery
In the methanation reaction process of Datang International Keshketen Coal-to-Natural Gas Co.,Ltd.'s methanation unit,after desulfurization and a large number of methanation reactions,the feed gas goes through the first supplementary methanation reactor 71-C104,and the design operating value of the outlet process gas temperature is 449℃.After passing through the feed gas preheater(71-W102/2)and boiler feed water heater(71-W109),the process gas is cooled to 169℃.The process gas passes through the air cooler(71-W201)and the process gas temperature is controlled by adopting the heat exchange mode of process gas and air.Although the air cooler has the advantages of saving water consumption,there is still a large amount of heat that cannot be recycled.For not putting the part of the heat is wasted and can be recycled so as to greatly reduce the energy consumption of the device and save the production cost.
