How to top up liquefied gas when the stabilization system is shut down? At what system pressure does water start to liquefy the gas?
1: It depends on what kind of water you use; it’s usually recycled water, to maintain the inlet pressure. 2: The liquid hydrocarbon pump vents pressure to the flare; pay attention to whether the vent line freezes – steam protection can be used to prevent the valve from freezing shut. 3: Fill the pump; if water is observed in the outlet drain, start the pump. A pressure of over 0.7 MPa is generally sufficient for the water to push things along; be sure to inform the customer on the other end.
What is the pressure of your circulating water? 0.7Map starts liquefying gas at the water surface – isn’t there a risk that the liquefied gas will mix into the circulating water?
The incoming water pressure for the circulating water is 0.4 MPa; it needs to be pressurized using a hydrocarbon pump, as it cannot be pushed by water pressure directly.
