Gas
A gas is a gaseous substance under standard temperature and pressure conditions. It can be of natural origin or derived from various chemical processes. Here are the main characteristics of the gas
Natural gas
A mixture of light hydrocarbons, mainly methane (CH ) extracted from underground deposits. It can also contain ethane, propane, butane and impurities such as hydrogen sulfide, carbon dioxide and nitrogen.
Сжиженный природный газ (СПГ)
Natural gas cooled down to -162°C to be converted to a liquid state, which facilitates transportation and storage.
Liquefied hydrocarbon gas (LPG)
A mixture of propane and butane derived from natural gas or oil processing. It is used in household (for example, in cylinders for gas stoves) and industry.
Using
Natural gas is widely used for heating, power generation, transportation and industrial fuels as raw materials for chemical products, fertilizers and hydrogen.
Benefits
- High Energy Efficiency.
- Relatively low carbon and combustion pollutant emissions compared to coal and oil.
- Can be used as a backup or primary power source.
Economic importance
An important energy resource affecting the world economy and energy security. The main producers are Russia, the USA, Canada, Iran and Qatar.
Natural gas plays an important role in the transition to cleaner energy, acting as an intermediate step between coal and renewable energy.
