Abstract
A system and method for purging a bottom slurry circuit isolation valve using hydrocarbons.
Claims8
A method of purging an isolation valve comprising:
- distilling an oil feedstock into different hydrocarbon fractions using a fractionation tower, the fractionation tower comprising 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 a liquid purge medium created in the fractionation tower.
A method for reducing cavitation in a slurry line of a fractionation system comprising:
- purging an isolation valve controlling flow of a process fluid through the slurry line with a liquid purge medium derived from a fractionation tower associated with the slurry line.
