In the process of natural gas extraction, transportation and use, there is often a situation where low-pressure gas is not fully utilized. As an important equipment in the natural gas industry, CNG recovery compressor helps to maximize the utilization of these low-pressure gases and improve energy utilization efficiency.
Working principle
The main task of the CNG recovery compressor is to pressurize low-pressure natural gas to the required high-pressure state, usually for storage or supply to CNG vehicles. Its basic working process is as follows:
Gas collection: Low-pressure gas is collected through pipelines or equipment. These gases may come from natural gas fields, gas pipelines or gas stations.
Compressed gas: After multi-stage compression, the pressure of low-pressure gas is increased to a range of 200-250 bar for storage and transportation. Each stage of compression is pressurized by equipment to gradually increase the pressure of the gas.
Storage and transportation: The compressed natural gas is stored in high-pressure gas storage tanks or transported to where it is needed, such as CNG filling stations, for subsequent use.
Application fields
1.CNG filling station
At the CNG filling station, the CNG recovery compressor can recover the low-pressure gas in the station and store it under pressure to avoid waste and ensure the efficient operation of the filling station.
2.Natural gas field and gas field processing
During the natural gas extraction process, low-pressure gas is often not used in time. The CNG recovery compressor recovers these gases and sends them to the gas storage system by pressurization, effectively improving the resource utilization rate of the gas field.
3.Natural gas pipeline system
During the gas transportation process, there may be unstable pressure or gas leakage in the pipeline network. The CNG recovery compressor can effectively recover these low-pressure gases to avoid waste.
4.Industrial gas recovery
Some industrial processes produce waste gas. The CNG recovery compressor can recover the natural gas components in the waste gas, reduce environmental pollution and improve resource utilization efficiency.
Technical characteristics and advantages
1.Efficient energy recovery
CNG recovery compressors can effectively reduce natural gas waste and improve energy utilization efficiency by recovering low-pressure gas.
2.Environmental benefits
By reducing the emission of low-pressure gas, CNG recovery compressors help reduce greenhouse gas emissions and meet global environmental protection needs.
3.Economic Benefits
By recycling low-pressure gas and using it under pressure, natural gas compressors can save energy costs for enterprises and improve economic benefits.
4.System Stability
Recycling compressors can help balance the gas pressure in the pipeline network and ensure the stable operation of the gas transmission system.
CNG recycling compressors are one of the key equipment in natural gas processing and refueling systems. They are mainly used to recover unused natural gas and store or transfer it by pressurization to ensure efficient use of natural gas, reduce waste, and improve energy utilization. They have important environmental and economic significance.
