Introduction to LNG high-pressure transfer pump technology

The LNG coming out of the recondenser goes directly into the LNG high-pressure transfer pump; once the pressure of the LNG reaches the levels required for transmission through the pipelines, it enters the vaporizer where it is heated and vaporized. The natural gas, after being metered, is sent through pipelines to the main transmission lines. A pump return line interface is provided on the high-pressure output manifold, with the returned LNG flowing into the recondenser. The high-pressure transfer pump operates at a constant speed. Its flow rate is controlled by a flow control valve installed on the gasifier feed line. An HV valve is installed on the outlet pipeline of each pump; its function is to ensure that the outlets of the operating pumps operate at the same flow rate and to cut off the flow in emergency situations.
Are you referring to the process flow during LNG liquefaction?
What was said upstairs is incorrect; I’m talking about the technology related to high-pressure pump systems.
Hello, senior. I would like to ask you: LNG city peak-shaving stations are different from receiving stations. If there is no additional condenser before the high-pressure export pump in such peak-shaving stations, how is the system designed to ensure the proper operation of the high-pressure pump? Please help clarify this for me.
