Question: (DMTO) Olefin separation unit: What should be done when the pressure at the outlet of the propylene refrigeration compressor is high? (1) Open the manual valve at the outlet of the condenser circulating water ； (2) The system cannot discharge non-condensable gas ； (3) Contact the utility department to lower the circulating water temperature. Note: The answer will be announced automatically in two days!
A. Open the water valve at the outlet of the outlet condenser. B. Reduce the amount of refrigerant used by the users who separate the refrigerant. C. Decrease the load on the pyrolysis gas. D. Remove the non-condensable gases from the system
1. Open the water valve at the outlet of the exit condenser； 2. Reduce the amount of refrigerant used by users who separate it for their own use ； 3. Reduce the pyrolysis gas load ； 4. The system fails to discharge non-condensable gas.

Open the water valve at the outlet of the exit condenser to reduce the amount of refrigerant used by the users who separate the refrigerant, thereby lowering the load on the pyrolysis gas; as a result, the system does not produce any non-condensable gases.
Open the water valve at the outlet of the exit condenser to reduce the amount of refrigerant used by the users involved in separation, thereby lowering the load on the pyrolysis gas; this helps prevent the system from producing non-condensable gases
