Question: (DMTO) Olefin separation unit: If the outlet temperature of the propylene refrigeration compressor continues to rise during acceleration, it is possible to prevent the compressor from being shut down due to high outlet temperature by using (). (1) Increase the opening degree of the spray valves in stages 1 and 2. (2) Reduce the minimum flow return for each stage. (3) Increase the rotational speed to lower the suction pressure and temperature in stage 1. Note: The answer will be announced automatically after two days!
Increase the opening degree of the sprays in suction tanks 1, 2, and 3, reduce the minimum flow rate for return in each section, and increase the rotation speed to lower the suction pressure and temperature in section 1
Increase the spray opening of the suction tanks in stages 1, 2, and 3, reduce the minimum flow return for each stage, and increase the rotational speed to lower the suction pressure and temperature in stage 1
Answer: (1) Increase the opening degree of the spray valves in stages 1 and 2; (2) Reduce the minimum flow return for each stage; (3) Increase the rotational speed to lower the suction pressure and temperature in stage 1
Increase the spray opening of the suction tanks in stages 1, 2, and 3, reduce the minimum flow return for each stage, and increase the rotational speed to lower the suction pressure and temperature in stage 1
Answer: (1) Increase the opening degree of the spray valves in stages 1 and 2; (2) Reduce the minimum flow return for each stage; (3) Increase the rotational speed to lower the suction pressure and temperature in stage 1
(1) Increase the opening degree of the spray valves in stages 1 and 2. (2) Reduce the minimum flow return for each stage. (3) Increase the rotational speed to lower the suction pressure and temperature in stage 1
1. Increase the opening degree of the sprayers in the first, second, and third suction tanks； 2. Reduce the minimum flow rate for each section and return ； 3. Increase the rotational speed to reduce the suction pressure and temperature for a period of time.
Increase the opening degree of the sprayers in stages 1, 2, and 3 of the suction tank； Reduce the minimum flow rate for each section and return ； Increase the rotational speed to reduce the suction pressure and temperature for a period of time
Increase the spraying intensity of the inlet tanks in each section
