The graywater heater has poor heat exchange efficiency; how to deal with it?
Thread Content
The graywater heater has poor heat exchange efficiency, resulting in a large amount of flash gas and overpressure in the shift stripper. How should this be addressed? Master’s guidance
I. Directly cut off the accident flare, with partial venting； II. Reduce the temperature of the gasifier, thereby lowering the temperature of the black water ； III. Increase the pressure in the high-pressure flash system to reduce the amount of flashing ；
Reduce the system circulation volume and lower the amount of black water discharged； Reduce the deaerator temperature and the graywater temperature ； The high-flash vapor fraction is discharged outside ； Increase the circulating water volume of the air lift tower heat exchanger
It is possible to reduce the drainage volume, but this is not very beneficial for the system; if the heat exchange performance is poor, it is best to switch the heat exchanger to bypass mode or use a high-flash vapor torch for venting in order to carry out maintenance on the heat exchanger.
