Online monitoring system for volatile organic compounds in flue gas

Model: CEMS-V100

　　Product Description, Technical Parameters, and Configuration

The CEMS-V100 online monitoring system for volatile organic compounds (VOCs) in flue gas is an online monitoring device developed by Tianrui Instrument, which can measure various organic compounds such as total hydrocarbons (THC), methane (CH4), non methane total hydrocarbons (NMHC), and benzene derivatives (BETX) in flue gas. This system can be widely used for monitoring VOCs emissions from various industrial pollution sources, such as semiconductors, electronics, pharmaceuticals, petrochemicals, chemicals, printing, automobiles, coatings, rubber, and other industries. It has stable and reliable performance and high integration. At the same time, Tianrui can provide customized solutions for various working conditions and customer needs, including explosion-proof cabinet type, full process high-temperature tracing type, mobile monitoring vehicle, etc.

　　Performance advantages:

The analysis method adopts GC-FID method, which complies with the national standard method HJ/T 38-1999 and the US EPA standard;

Multiple detectors such as ECD, FPD, TCD, etc. can be optionally equipped to meet the needs of different sensitivities and detected substances;

The system has high detection sensitivity and can automatically switch between high and low ranges. Each target analyte has an independent detection limit;

The standard analysis time is 1 minute, which can provide real-time and continuous monitoring data;

High degree of automation, capable of automatic pipeline cleaning, with minimal instrument maintenance workload;

Equipped with real-time/timed system diagnosis and fault alarm functions;

Built in calibration module, adjustable calibration cycle, can achieve automatic quality control of the instrument;

The FID detector has an automatic ignition function, which automatically shuts off the gas system after the flame is extinguished to ensure system safety;

Built in integrated industrial computer, high-definition color LCD touch screen display, system software adopts layered modular design, and the operating interface is simple and easy to control;

Real time display of the operating status of various components in the system, and setting of instrument parameters for easy maintenance;

Can view real-time/historical monitoring data, automatically store data and graphs, and provide multiple report formats for selection;

It has multiple data transmission methods such as RS232/485, RJ45, USB, etc., which can achieve real-time data communication and connect to the monitoring platform of the environmental protection department;

Equipped with operation permission restrictions and password control functions to prevent operational errors or unauthorized operations;

We can provide customized solutions based on customer needs, including explosion-proof cabinet type, full process high-temperature tracing type, and mobile monitoring vehicle type
