Question: (DMTO) Olefin separation unit: What should be done when the outlet temperature of the propylene refrigeration compressor is high? (1) High circulating water temperature and low pressure ； (2) High compressor suction temperature ； (3) High compressor outlet pressure ； (4) There is non-condensable gas in the propylene gas. Note: The answers will be announced automatically in two days!
1. Reduce the compressor outlet pressure. 2. Reduce the suction pressure at the first stage of the propylene refrigeration compressor. 3. Reduce the load. 4. Discharge non-condensable gases
1. Reduce the compressor outlet pressure； 2. Reduce the suction pressure at the first stage of the propylene refrigeration compressor ； 3. Emission of non-condensable gases ； 4. Reduce the load.

Reduce the compressor outlet pressure, lower the suction pressure at the first stage of the propylene refrigeration compressor, reduce the load, and discharge non-condensable gases
(1) High circulating water temperature and low pressure； (2) High compressor suction temperature ； (3) High compressor outlet pressure ； (4) There is non-condensable gas in the propylene gas
High inlet temperature, high outlet pressure
