Natural Gas
Natural gas is a fossil fuel mainly composed of methane, along with small amounts of other hydrocarbons like ethane, propane, and butane. It is a clean and efficient energy source, widely used for heating, power generation, and industrial processes.
Compressed Natural Gas, CNG
CNG is natural gas compressed to high pressure for storage and transportation. It is typically stored in high - pressure cylinders at pressures ranging from 200 to 250 bar. CNG is a popular alternative fuel for vehicles due to its relatively low cost and lower emissions compared to gasoline and diesel.
Liquefied Natural Gas, LNG
LNG is natural gas that has been cooled to extremely low temperatures (-162°C) to convert it into a liquid state. This significantly reduces its volume, making it easier to transport and store. LNG is usually transported in cryogenic tanks and can be regasified and used in various applications.
- Natural Gas Extraction Equipment：Includes drilling rigs for drilling wells to access natural gas reserves underground, and wellhead equipment for controlling the flow of gas.
- CNG Compression Equipment：CNG compressors are used to compress natural gas to high pressures. These compressors can be piston - type, screw - type, etc. CNG storage cylinders, made of high - strength materials, are used to store the compressed gas.
- LNG Liquefaction Equipment：LNG liquefaction plants use refrigeration systems to cool natural gas to its liquid state. Cryogenic heat exchangers and expanders are key components in the liquefaction process. LNG storage tanks, which are insulated to prevent heat transfer, are used to store the liquid gas. LNG carriers are large ships designed to transport LNG over long distances.
