LNG Industry

The gas is first extracted and transported to a processing plant where it is purified by removing any condensates such as water, oil, mud, as well as other gases such as CO2 and H2S. An LNG process train will also typically be designed to remove trace amounts of mercury from the gas stream to prevent mercury amalgamizing with aluminium in the cryogenic heat exchangers. The gas is then cooled down in stages until it is liquefied. LNG is finally stored in storage tanks and can be loaded and shipped.

For this special application, the valve material that have to consider marine environment and sea water fluid. So to service this application, we should select special materials (duplex steels, nickel alloys) and also consider extreme service conditions (low temperature, anti wearing internals) to choose the best internal materials.
