The formula for calculating the gasification rate is: gasification rate of natural gas = number of urban non-agricultural gas-using population / total urban non-agricultural population x 100%.

The formula for calculating the gasification rate of LNG is: LNG gasification rate = 1000 kg / LNG gas density (kg/m3).

Natural gas consists mainly of methane (85%) and small amounts of ethane (9%), propane (3%), nitrogen (2%) and butane (1%). It is mainly used as a fuel, but also as a raw material for the manufacture of chemicals such as acetaldehyde, acetylene, ammonia, carbon black, ethanol, formaldehyde, hydrocarbon fuels, hydrogenated oils, methanol, nitric acid, synthesis gas and vinyl chloride.

Natural gas is compressed into a liquid for storage and transportation. Coal miners, nitric acid makers, power plant workers, organic chemical synthesizers, gas users, and petroleum refiners have exposure to this product.

Extended Information

Natural gas can be categorized into free, dissolved, adsorbed, and solid hydrates according to the phase in which it exists in the subsurface. Only natural gas in the free state can be developed and utilized after aggregation to form natural gas deposits.

Natural gas can be divided into associated gas and non-associated gas according to the form of storage generation.

Associated gas: accompanied by crude oil *** generation, and crude oil at the same time to be extracted from the oil field gas.

The associated gas is usually the volatile part of the crude oil, in the form of gas in the oil-bearing layer above, where there is crude oil in the stratum have, just oil, gas volume ratio is different.

Even in the same field the source of oil and gas is not necessarily the same. They are brought together in the same rock reservoirs by different routes and through different processes.

Non-associated gas: Includes both pure gas field gas and condensate field gas, both of which exist as gases in the formation. Condensate field natural gas flows from the formation out of the wellhead, as the pressure drops and the temperature rises.
