Explosion proof gas chromatograph for processThe core functions are as follows:
1、 Real time online monitoring and security protection
Real time analysis of hazardous gases
Explosion proof gas chromatograph for processBy using gas chromatography technology, real-time monitoring of gas components (such as methane, ethane, hydrogen sulfide, hydrogen, etc.) in industrial production can be achieved with a detection limit of up to ppb, meeting the requirements of high-precision analysis. For example, in the field of petrochemicals, the concentration of combustible gases in the reactor can be monitored in real time, the methane retention time fluctuation is controlled within ± 0.02 minutes, and the relative standard deviation of peak area is stable at around 1.3%.
Explosion proof design ensures safety
Explosion proof rating: Compliant with international standards such as EX db IIC T4 Gb, suitable for explosive gas environments (such as Zone 1 and Zone 2).
Electrical full separation: The explosion-proof gas circuit test box and the central control circuit box are independently installed and designed to reduce data upload packet loss rate and ensure stable operation in flammable and explosive environments.
Multiple protection mechanisms: integrated explosion-proof power supply, explosion-proof detector, automatic alarm, and gas/circuit cut-off functions to prevent explosions caused by electrical sparks or high temperatures.
2、 High precision and high stability analysis
Chromatographic separation technology
By utilizing the difference in distribution coefficients of different substances in the stationary and mobile phases, precise separation of gas components can be achieved. For example, the temperature control accuracy of the column temperature box reaches 0.1 ℃, and it quickly and stably reaches the set temperature during programmed heating, ensuring effective separation of different boiling point components.
High sensitivity detector
Equipped with TCD (thermal conductivity detector), FID (hydrogen flame ionization detector), FPD (flame photometric detector), etc., it can simultaneously detect organic matter, inorganic matter, and trace impurities. For example, in hydrogen energy detection, it meets the standard of GB/T 37244-2018 to detect trace impurities in hydrogen gas.
Data reliability verification
After weekly calibration with standard gas, the linear correlation coefficient of the calibration curve is above 0.998, which is basically consistent with the data of other detection equipment, ensuring the accuracy of the analysis results.
3、 Intelligent Control and Remote Management
automated operation
Preprocessing system: integrates explosion-proof injection, carrier gas pressure reduction, and flow path switching functions to reduce manual intervention.
Gas saving mode: Optimize the efficiency of carrier gas usage and reduce energy consumption.
Automatic injection calibration: supports timed automatic injection to improve analysis efficiency.
Remote monitoring and data transmission
Remote control and data transmission can be achieved through mobile mini programs (such as "Xiao Fang") or protocols such as 4-20mA and Modbus.
Support data storage, query, and output for process optimization and compliance management.
4、 Modular design and flexible adaptation
Multi channel and multi-component analysis
Support simultaneous analysis of 1-6 flow paths/1-12 components to meet complex process requirements. For example, in natural gas extraction, components such as methane, ethane, propane, and hydrogen sulfide can be monitored simultaneously.
Flexible installation method
Support wall mounted and floor standing installation to adapt to different on-site spaces. For example, the HA-9680 equipment has a size of 1300 × 1800 × 1000mm, high integration, and can replace existing equipment.
定制化配置
According to industry demand, explosion-proof alarm system, gas cut-off protection system, ventilation automatic control system, etc. can be selected to enhance equipment applicability.
