LNG/CNG refueling station specific calorific value analyzer
Product details
With the vigorous development of China's "West East Gas Pipeline" project, a nationwide trend of natural gas utilization has emerged. Natural gas, as the best energy source in the world, has been highly valued in the selection of urban gas sources in China, and vigorously promoting natural gas has become China's energy policy. However, due to the large scale, high investment, and long construction period of long-distance natural gas pipeline transportation projects, it is difficult for long-distance pipelines to reach most cities in a short period of time. By using high pressure to reduce the volume of natural gas by about 250 times (CNG) for transportation, and then reducing its pressure, the problem of natural gas sources in some cities has been solved. The application of ultra-low temperature freezing technology turns natural gas into liquid (reducing its volume by about 600 times), and the use of ultra-low temperature insulation tanks to transport natural gas over long distances through vehicles, trains, ships, and other means, and then store and gasify it in ultra-low temperature insulation tanks. Compared with CNG, the LNG supply method has higher transportation efficiency, stronger safety and reliability, and can better solve the problem of urban natural gas sources.
LNG, as an energy source, has the following characteristics:
LNG combustion produces almost no pollution.
The reliability of LNG supply is guaranteed by the contracts and operations of the entire chain.
The safety of LNG is fully guaranteed through strict adherence to a series of international standards in the design, construction, and production processes. LNG has been in operation for 30 years without any serious accidents.
LNG, as an energy source for power plants, is beneficial for peak shaving, safe operation and optimization of the power grid, as well as improvement of the power structure.
LNG, as an urban energy source, can greatly improve the stability, safety, and economy of gas supply.
The wide range of applications of LNG
LNG, as a clean fuel, is bound to become one of the main energy sources in the new century. To summarize its uses, it mainly includes:
Used for peak load and accident peak shaving of urban pipeline gas supply
Used as the main gas source for pipeline gas supply in large and medium-sized cities
Used as a gas source for LNG community gasification
Used as fuel for refueling cars
Used as aircraft fuel
Cold energy utilization of LNG
