Oil and Gas Industry
After the LNG natural gas is collected, it needs to be liquefied to facilitate storage and transportation. The import and export of LNG is generally carried out by ship, and then arrives at the receiving station for re-gasification. The gasified natural gas is transported to the urban pipeline network to each household through the pipeline. After the natural gas is collected, a series of purifications are required. The natural gas is pretreated to remove impurities such as heavy hydrocarbons, sulfides, CO2, and water, and then cooled to -160 degrees at room temperature before it can be liquefied. All gaseous and liquid extraction, transportation and storage will use valves, usually cryogenic globe valves, cryogenic gate valves, cryogenic ball valves, cryogenic butterfly valves, etc.
