What should be paid attention to when using CNG pump
The CNG unloading system utilizes a skid-mounted design, offering significant advantages such as high integration, lower investment costs, and shorter construction periods. This system is an effective solution for regions with multiple remote gas wells and excess CNG production capacity, as it allows for the recovery of vented gas during natural gas exploration and development. By reducing gas waste in test production processes, the system not only conserves valuable natural gas resources but also minimizes environmental impact. Moreover, it can be installed at gathering stations, where recovered gas is depressurized and injected into the gas transmission network. This process helps to reduce carbon emissions, contributing to the achievement of "dual carbon" goals, while simultaneously generating considerable economic and social benefits.
For safe and efficient operation of the CNG unloading system, several precautions must be observed on-site:
Pre-Operation Check: Before each use, inspect the control and protection unit to ensure all indicators, such as lights, reheater temperature, and instrument air pressure, are displaying normal values. Also, check valve positions and the process flow.
Unloading Process: Once checks are complete, open the unloading valve to begin using the CNG depressurization skid.
Routine Inspection: During unloading, conduct periodic inspections to monitor pressure, temperature, and flow parameters. Record data and assess equipment condition, including noise levels and seal integrity at junctions.
Emergency Response: In cases of abnormal operation, such as overpressure or gas leakage, the system will automatically trigger alarms or interlocks, activating emergency shut-off valves to stop gas intake.
Shutdown: For regular shutdowns, close the unloading valve, intake valve, and any auxiliary equipment as required by the process.
Maintenance: Regularly open and close valves, lubricate them, and ensure their smooth operation.
Instrument Calibration: Periodically test and calibrate instruments, gas detectors, and interlock protection systems to ensure data accuracy and system reliability.
