In the event of an emergency power outage in the hydrogenation unit, should the inlet and outlet ball valves of the hydrogen circulation pump be closed?
Thread Content
I would like to ask the experts: In the event of an emergency power outage in a hydrogenation unit, should the inlet and outlet ball valves of the hydrogen circulation pump be closed?
What exactly is an inlet/outlet ball valve?
If this ball valve is considered to be a shut-off valve, it must be closed in order to protect the hydrogen circulation pump
There’s no need to worry about the reciprocating machine! Emergency shutdowns can be ignored! Wait until it’s completely stopped before arranging to turn it off! If it is a turbine cycle machine, it is best to shut down at least one of the valves at the outlet or inlet as soon as possible.
A track ball valve is designed for manual, rapid closure in emergency situations; it functions in the same way as a regular valve, but it can be easily and quickly closed manually.
