Product Introduction:

According to user requirements and the latest national security standards for the use of natural gas, our company has developed and producedNatural gas online fully automatic analyzer system.The entire system includesSampling unit, sample gas processing system, analysis host, supporting cabinet and power supply, gas component calibration unit, etc. Sampling unit andThe natural gas supply pipeline is directly connected, and real-time online sampling is carried out. The extracted sample gas is purified and sent to the gas chromatography analyzer host for testing, which can achieve 24-hour continuous and uninterrupted testing. Upload the detection data to the user control room through the DCS system. The instrument is fully connected to other devices through network transmission and D/A conversion, meeting the requirements of DCS system.

Natural gas online fully automatic analyzer systemFeatures:

• The natural gas online fully automatic analyzer system is a carefully designed automated detection system by our company based on years of production of chromatography instruments, according to the actual situation of the natural gas industry, and in response to the characteristics of continuous monitoring, complex sampling, and the need for safety and explosion prevention in the production and gas supply process. The system runs fully automatically, reducing human error for operators, ensuring fast, safe, and stable detection during the production process, and meeting the user's usage requirements.
• The natural gas online fully automatic analyzer system uses a vacuum pump and multiple (single) core stainless steel pipes (or dedicated pipes) to extract gas samples from each monitoring point. The microcomputer controlled dedicated gas chromatograph continuously analyzes the natural gas sample composition content, natural gas calorific value, density, Huabai number, etc. at each detection point in real time.
• Adopting advanced domestic automatic control technology to maintain long-term stable operation.
• Automatic sampling is controlled by imported solenoid valves and stepper motors, which are accurate, reliable, and have a long service life.
• The analysis software has automatic display, automatic storage, and is equipped with various output interfaces such as R485.
• Adopting dual time control injection and making real-time modifications as needed.
• This system has strong specificity, simple operation, and high cost-effectiveness.
• High work efficiency, able to achieve 24-hour continuous cycle monitoring, automatic sampling saves manpower and material resources, reduces labor intensity, protects personnel from harmful gas injuries, and greatly improves work efficiency.
• The host of the gas chromatography analyzer and other main supporting instruments of the system are installed in an explosion-proof cabinet to ensure safe and explosion-proof protection during the analysis process. The entire system meets the requirements of ExdIIBT4 explosion-proof level and IP65 protection level.
