Research and Application of Miniaturization Explosion-Proof Total Hydrocarbon Analyzer System
To achieve combustible gas monitoring requirement,this article develops an explosion-proof online total hydrocarbon analyzer that can be applied in explosion-proof sites and accurately measure the concentration of combustible gases.The analyzer is based on the principle of hydrogen flame ionization(FID),and can achieve online monitoring of total hydrocarbon concentration,and transmit the monitoring results in real-time to the instrument control system of the chemical factory.The results showed that the instrument response time(T90)was less than 3s,baseline noise was 0.07pA,baseline drift was 0.37pA/30min,quantitative repeatability was 0.41%,and measurement error was 0.35%.The experimental results indicate that the instrument has advantages such as quick response,small error,high reproducibility,and good stability.This product has been successfully applied in chemical industrial parks and is fully suitable for online monitoring of total hydrocarbon concentration in complex working conditions of petrochemical enterprises.
