Stirred tank reboiler temperature
Thread Content
The naphtha boiling range is 35–127; the pressure in the reflux tank is 0.7 Mpa and the temperature is 60°C. Will some of the naphtha be distilled out along with the vent gas?
The reflux tank is pressure-controlled. It is only to remove non-condensable gases; the amount of naphtha vapor removed at 60 degrees should be minimal. If discharge occurs continuously, more naphtha vapor will be carried away, so the temperature of the reflux tank should be lowered.
Is the backflow load too high? Can’t it be cooled by air cooling? 60°C is relatively high; usually it’s 40°C.
Surely some non-condensable gas will be discharged along with the gas, it’s just a matter of how much
