What is the function of the hydrogen supply line in a hydrogenation unit?
Thread Content
Dear experts, in a hydrogenation unit, there is a hydrogen supply line at the outlet of the feed oil pump. What is its specific function? Thank you so much!
Are you referring to the hot hydrogen purge line?
Blow the hydrogen line; shut down the system and drain the oil.
Yes, for the hydrogen purging line, the pipeline from the pump outlet to the hydrogen mixing point is quite long; when the system is shut down, there is still fluid in this section of pipeline, so hydrogen is used to remove that fluid from it
During emergency shutdowns or regular shutdowns, purge the pipelines behind the pump after shutting it down to prevent dead oil from condensing within those pipelines
Oil removal purging to remove oil remaining in dead zones.
