The condensate from the heat exchangers in the maleic anhydride plant is fed into demineralized water
Thread Content
Deoxygenated water heat exchanger: A flow control valve for the steam entering the heat exchanger and a valve for introducing deoxygenated water into the condensate line are used to achieve split-control; the principle is to add deoxygenated water to the condensate in order to reduce the amount of condensate discharged
Yes, the condensate water in the deoxygenated water heat exchanger of the maleic anhydride plant can be subject to segmented control by adjusting the steam flow control valve fed into the heat exchanger and the brine feed control valve in the condensate line. In this way, the amount of condensate discharged can be reduced, thereby improving the efficiency of the system. .
