Reasons for oil leakage in screw-type chlorine liquefaction units and low liquefaction efficiency
Thread Content
Hello everyone, could you please help analyze the reasons for the low liquefaction efficiency and oil leakage in the chlorine liquefaction unit? I’m waiting for your reply. Thank you

Low chlorine pressure ； 6. The exhaust gas regulation is set too low, failing to remove all of the exhaust gas and resulting in low cumulative purity ； 7. Insufficient refrigerant. What does oil leakage refer to? Is it leakage from the mechanical seal or an inability to separate the oil? Oil leakage from the mechanical seal is due to installation issues or quality problems with the seal. The inability to separate the oil is caused by improper start-up and shutdown procedures, as well as inadequate control of the oil temperature on a regular basis.
By oil leakage you mean that the oil level in the oil is dropping, right? There are many possible reasons; it is usually a system issue, related to oil temperature, fluid supply, exhaust temperature, etc. It would be best if you could provide the operation data so that I can help analyze and identify the cause.
This problem does not exist in the chlorine condenser of the liquefaction unit. The size of the delivery pipeline affects the flow rate, but it has no direct effect on the condenser.
Oil separator malfunction; check the filter element； Oil temperature is too low or too high ； The return flow of oil to the liquefier is poor; is the oil level continuously rising? ；
Is it possible that the refrigeration oil has gotten into the condenser?
