What are the typical alarm values for high pressure difference at the inlet and outlet of the air cooling tower in an air separation unit, as well as the alarm value for low outlet pressure?
Thread Content
I would like to ask those with more experience: what are the typical alarm values for high pressure difference at the inlet and outlet of the air-cooled tower in an air separation unit, as well as the alarm value for low outlet pressure? {:3_46:}
The design resistance for air-cooled towers is generally 5 kPa; the alarm threshold can be set based on the actual operating values. The outlet pressure of air-cooled towers is usually set with a low-limit alarm at 400 kPa, and an interlock trigger at 350 kPa~~
