What is the difference between the CPF opening and closing systems in oil fields?
Thread Content
I’m not in the field of engineering, but my work is related to oil construction; therefore I’d like to know what the differences are between the CPF opening and closing systems in oil fields. A simple explanation will be sufficient, thank you!
The media stored in open and closed tanks are related to system pressure, as well as the toxicity and flammability of the media. For low-pressure, harmless substances, discharge is allowed; for high-pressure, toxic substances that are also flammable and explosive, discharge must be prevented. I’m not sure if this is easy to understand.
I didn’t expect the difference in terms of media; thank you!
A closed-system setup involves the use of a waste tank, whose vent is connected to a flare system for discharging waste under pressure. The drainage system usually consists of a sewage tank or a waste collection container that is connected directly to the atmosphere; it is used for draining waste under gravity without any pressure, during startup, shutdown, or maintenance activities, as well as for draining water from floor drains.
Thank you, this explanation fits well the characteristics of oil fields.
