Analysis System for Oxygen Content of Electric Tar Generator in Coking Plant

The policy is to provide our company with a continuous monitoring system for flue gas emissions based on the emission characteristics of your company's pollution sources. All probes and sampling system components are made of corrosion-resistant materials, among which the probe material is special acid resistant stainless steel (316L), the filter material is ceramic, and the sampling heat tracing pipeline is a specially customized Φ 8 polytetrafluoroethylene heat tracing tube. Ensure the requirement of continuous and reliable operation under the working conditions of your company.

The CEMS system consists of sampling probes, dust meters, and temperature pressure flow integrated probes placed on the chimney, as well as analysis cabinets, standard gases, and air compressors placed in the cabin. The sampling probe is responsible for flue gas sampling, and high-temperature heat tracing is used to prevent water vapor condensation in the flue gas. The built-in sintered filter element is used to filter dust in the flue gas; The dust meter is used to measure the concentration of chimney dust, and the temperature pressure flow is used to measure the temperature, pressure, and flow velocity of the flue gas inside the chimney; The analysis cabinet is responsible for extracting smoke and directly measuring SO2, NOx, and O2 indicators; Standard gas is used for calibrating analytical instruments; The air compressor generates compressed air, which is used for regular blowback of the heat tracing pipeline, sampling probe, temperature and pressure flow, and gas supply for ultra-low dust analyzer.

CEMS provides a data availability rate of over 98%.

CMES provides a comprehensive data acquisition system (DAS) with functions such as display monitoring, data processing, report management, remote communication, remote monitoring, and abnormal alarm.

The gas analysis of CEMS adopts the extraction condensation method (full process heat tracing direct extraction method with added acid condensation device), the smoke measurement adopts the backscattering method, the flow measurement adopts the differential pressure flowmeter, and the temperature measurement adopts the platinum resistance method, which meets the requirements of the relevant "Technical Specification for Continuous Monitoring of Flue Gas Emissions from Fixed Pollution Sources (Trial Operation)" (HJ/T75-2017)

Analysis System for Oxygen Content of Coke Oven Gas

Can continuously monitor the concentration of particulate matter and sulfur dioxide online（SO2)Concentration, nitrogen oxides(NOx)Concentration, oxygen(O2)Content, flue gas temperature, flue gas pressure, flue gas flow rate, and carbon monoxide can also be increased(CO)Carbon dioxide(CO2)Ammonia gas(NH3)Hydrocarbons(CHX)Measurement of humidity and other parameters. Its control computer can process and store the measured data; It can be connected to the computer of the higher-level environmental protection department through the network, and the environmental protection department can easily and quickly access monitoring data. Enterprises can operate databases internally through domain networks based on access permissions, such as reading data, modifying status parameters, and even directly operating systems. Due to the use of direct extraction method to measure the concentration of pollutants in flue gas, the system can calibrate the analyzer online with standard gas to ensure the accuracy of monitoring data. Gas analysis uses non dispersive infrared absorption method; The monitoring of oxygen content adopts paramagnetic oxygen analysis with a lifespan of up to ten yearsinstrument.
