Online monitoring of volatile organic compounds (VOCs) in benzene derivatives

　1、 Product Introduction

Our company's independently developed TK-1200Online monitoring of volatile organic compounds (VOCs) in benzene derivativesAdopting advanced full process high-temperature heat tracing pretreatment, gas chromatography technology (GC), and hydrogen ion flame detection method (FID), this series of online gas chromatography analyzers is mainly used for real-time monitoring of organic matter emissions from various industrial pollution sources. The new technology is adopted, with stable and reliable performance, high degree of automation, wide detection range, and can measure multiple parameters such as VOCS, total hydrocarbons (THC), methane (CH4), non methane total hydrocarbons (NMHC), etc. The concentration and emission rate of VOCs are continuously and real-time tracked and monitored, and all monitoring parameters are transmitted to industrial computer software and user DCS system. It can communicate with the data system of the environmental protection department through data acquisition instrument. The system equipment is placed in the analysis cabin, which is easy to operate and maintain. It has functions such as real-time transmission of on-site data and remote fault diagnosis, achieving unmanned operation of the work site. The entire system has a simple structure, modular design, strong stability, and low operating costs.

　　2、 Technical parameters

　　3、 Technical advantages

The environmental product certification certificate CCEP, testing report, and system comply with the technical requirements of the national standard HJ1013;

The online chromatograph adopts injection pressure balance technology, with minimal sample injection error and accurate measurement;

Adopting multi-stage precision dust removal, the pipeline is made of weak adsorption material with self-cleaning function, which can effectively backwash and clean impurities such as particles in the sample, avoiding pipeline blockage. It is suitable for harsh conditions such as high temperature, high humidity, high concentration, and high dust;

Extraction sampling method, adjustable heat tracing temperature, high temperature tracing from the sampling probe to the analytical instrument throughout the entire process, temperature setting of 120-180 ℃, and no condensation in the entire gas flow path;

The system adopts EPC technology to control the flow rates of carrier gas, air, and hydrogen, with high accuracy and good repeatability;

The system has comprehensive alarm functions, including over temperature alarm function and main component fault alarm function;

The system has an automatic ignition function. In the event of program interruption due to external influences or brief tripping, the system can automatically start, ignite, and resume operation after power is restored.

The system has calibration function. The entire system calibration starts from the probe and calibrates the entire system's gas path;

● Independently develop data collection and analysis software, which can be adjusted according to the needs of enterprise users;

The system can record, store, display, query, export, transmit, and print reports and data reports for any time period. The format should be consistent with the report format required by the environmental protection department, and historical data should be saved for at least 3 years.
