How to solve the high outlet temperature due to pressure control in the rich liquid flash tank?
Thread Content
After the desulfurization unit started operating, the temperature of the gas discharged from the rich liquid flash tank under pressure control remained high; this was not an issue in the previous cycle, as the temperature of the gas discharged under pressure control was normal. Currently, all other parameters are fine. Moreover, due to the high exhaust temperature and liquid in the exhaust, the liquid level in the large solvent tank has also been dropping continuously. I would like to ask experts: what are the reasons for the high exhaust temperature in the rich liquid flash tank? How can the exhaust temperature be reduced?
Does your rich liquid come from the circulating hydrogen desulfurization tower?
