SYSTEMS AND METHODS FOR PURGING AN ISOLATION VALVE WITH A LIQUID PURGE MEDIUM

An isolation valve purge system for an isolation valve, with internal components configured to isolate the flow of process fluid through the bottom slurry circuit line. In some embodiments the isolation valve is purged using a liquid purge medium created in the fractionation tower, such as a hydroca...

Beschreibung
Zusammenfassung:	An isolation valve purge system for an isolation valve, with internal components configured to isolate the flow of process fluid through the bottom slurry circuit line. In some embodiments the isolation valve is purged using a liquid purge medium created in the fractionation tower, such as a hydrocarbons, oils of different viscosity or a combination of hydrocarbons. A method for reducing cavitation in a pressurized line by using a hydrocarbon from the fractionation tower to purge an isolation valve process fluid flowing therethrough with a liquid purge medium.
