Focuses on professional purification of natural gas and oilfield associated gas, and builds a complete technical system of "Four Removals" treatment and liquefaction to produce LNG.

"Four Removals" Treatment: Removes impurities and harmful substances in gas through desulfurization, decarbonization, dehydration, and hydrocarbon removal processes, enabling natural gas to meet high standards for pipeline transportation and providing a foundation for clean energy transmission.

Natural Gas Liquefaction to LNG: Relies on advanced liquefaction technology to convert purified natural gas into liquefied natural gas (LNG), realizing efficient energy storage and convenient transportation, and promoting the wide application of natural gas in the energy field.
