Hey all,
We have a linde design cryogenic hydrogen recovery unit at our plant. It's cold box has a pressure control valve on hydrogen product line. That valve is installed inside the cold box with its actuator outside so that could easily be removed for maintenance in shutdown.
My question is that can we remove the actuator along the valve plug for maintenance with out deriming of cold box or is it necessary that for even minor maintenance at cold box we first have to derime it?
Kindly suggest.
Thanks
