Abstract
A system and method for purging a bottom slurry circuit isolation valve using hydrocarbons.
Claims14
An isolation valve liquid-purge system comprising:
- an isolation valve configured to control the flow of process fluid comprising:
- a gate;
- a housing configured to receive the gate;
- a seat configured to seal against the gate;
- an actuator configured to actuate the gate;
- and

4 more elements
A method of purging an isolation valve comprising:
- distilling oil feedstock into different hydrocarbon weights using a fractionation tower having a bottom slurry circuit;
- controlling the flow of bottom slurry through the bottom slurry circuit with an isolation valve wherein the isolation valve is purged using liquid purge medium created in the fractionation tower.
A method for reducing cavitation in a line comprising:
- purging an isolation valve controlling a line with process fluid flowing there through with a liquid purge medium.
