Volatile Organic Compounds (VOCs) Online Monitoring System

1、 Product Introduction

Shandong Xinze Instrument independently developed TK-1200The online monitoring system for volatile organic compounds in pollution sources adopts advanced technologyFull process heat tracing pretreatment+Online chromatography technology+Flame ion detection method（FID）Mainly used for real-time monitoring of organic matter emissions from various industrial pollution sources, this series of online gas chromatography analyzers adopts XianjinTechnology, stable and reliable performance, high degree of automation, wide detection range, capable of measuringVOCSTotal hydrocarbons（THC）Non methane total hydrocarbons（NMHC）Various parameters such as benzene and its derivativesVOCSContinuous and real-time tracking and monitoring of concentration and emission rate, and transmission of all monitoring parameters to industrial computer software and usersDCSThe system can communicate with the data system of the environmental protection department through a 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、 System composition

TK-1200The volatile organic compound online monitoring system consists of a gaseous pollutant monitoring subsystem3100Type online gas chromatograph (non methane total hydrocarbons)（NMHC）&Benzene derivatives), smoke parameter monitoring subsystemSVPT-100Type Pitot Tube(Temperature, pressure, flow rate)andSSD-100The humidity meter, system control and data acquisition and processing subsystem, and calibration and auxiliary subsystem are composed of four basic parts.

3、 System features

Equipped with a touch screen and menu style operation, different configurations can be achieved VOCsComponent concentration, methane/Non methane total hydrocarbon concentration and comparative analysis before and after treatment;

Adopting gas chromatography monitoring method, in compliance with national standards, with short analysis cycle and accurate measurement; The system can achieve automatic zero and range calibration function (switching standard gas mode);

The flow path from the sampling probe to the analytical instrument adopts a full process approach 125 Heat tracing without any cold spots;

The sample has no adsorption or blockage phenomenon; The entire flow path and component materials are suitable for harsh working conditions with various mixed components such as high temperature, tar, high pressure, and high corrosion, to prevent blockage and corrosion.

Microcomputer and system control software, fully automatic monitoring and analysis of environmental air during sequential operation C2-C12Volatile organic pollutants;

The system has functions such as operation, alarm, interlock, reverse blowing, calibration, etc., ensuring long-term operation of the system. At the same time, it has self diagnostic function, reducing maintenance workload and costs.

4、 System application

Online monitoring of exhaust emissions in industries such as petrochemicals, pharmaceuticals and pesticide manufacturing, automotive manufacturing, furniture manufacturing, semiconductor manufacturing, printing, and spraying.
