The outlet flow rate of the high-flash separation tank is out of range

First, let’s take a look at what this traffic design value is Generally, design institutes do not make mistakes in selecting insufficient instrumentation. First, check whether the instruments are operating properly, as the vapor from the flash system contains dust; also verify whether the pressure tapping tubes of the flow meters are blocked. If it is confirmed that the gauge is functioning properly and there is no blockage. Check the high-pressure flash conditions to see if the pressure in the high-pressure flash unit is too high or even exceeds the allowable level. If the pressure is too high or exceeds the limit, it indicates that the load on the high-pressure flash unit is too great. In such a case, not only will the high-pressure flash unit experience overpressure and overheating, but the low-pressure and vacuum flash units as well will suffer from overpressure and overheating as well; the entire flash system is operating under excessive load. If the above two reasons are ruled out, then the problem must lie with the measuring instrument; replace it with a new one.

First, check whether the gauge readings are accurate; it’s likely that the readings are incorrect. If it is confirmed that the flow meter is giving accurate readings, then it indicates that the heat exchange efficiency in the two exchangers used for high-flash point treatment is poor, especially in the final cooler for high-flash point treatment. Check whether there is any opening in the gas-phase bypass line, as this could cause a short circuit in the exchanger. Also, examine the temperature difference and flow rate of the cooling water inlet and outlet.
