Top 100 Fast-growings companies in Liquefied natural gas
by Most Patent Filing In 1 Year in the China in 2021

The Liquefied natural gas top 100 is Discovery PatSnap’ annual ranking of the top 100 Most Patent Filing In 1 Year Liquefied natural gas Fast-growings in the China. Discovery has identified the top key players, startups & unicorns, fast-growings, news entrants in 2021, ranking from differnt perspectives, including patent filing intensity, academic research capability, news media heat. The company list is generated from various data types.
Liquefied natural gas (LNG) is natural gas (predominantly methane, CH₄, with some mixture of ethane, C₂H₆) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state (at standard conditions for temperature and pressure). It is odorless, colorless, non-toxic and non-corrosive. Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia. The liquefaction process involves removal of certain components, such as dust, acid gases, helium, water, and heavy hydrocarbons, which could cause difficulty downstream. The natural gas is then condensed into a liquid at close to atmospheric pressure by cooling it to approximately −162 °C (−260 °F); maximum transport pressure is set at around 25 kPa (4 psi).
