Coke oven gas calorific value analyzer gas composition analysis chromatographic method Principles of Gas Chromatography

Composition and structure of coke oven gas calorific value analyzer：

Gas composition analyzerOne set of gas chromatograph mainframe

1. Dual thermal conductivity detector equipIndependent carrier gas sourceTwo independent gas path processes are controlled separately, with two injection systems. The automatic control system controls the valve switching time to achieve separate analysis of the calorific value of each component in coal gas by gas chromatography.

2. A set of high-purity hydrogen gas source (high-purity hydrogen generator or high-purity hydrogen gas cylinder model) for chromatographic gas source40L）. High purity nitrogen gas source

3. Dual channel calorific value version chromatographic analysis software Process the spectral signal data analyzed in coal gas, calculate the concentrations of each component in these gases, and provide the physicochemical property parameters of combustible gases in the analysis report, such as average molecular weight, density, calorific value, and white number. Using this software, establish a hierarchical spectral library directory framework, storing spectra from different sampling points in a custom directory for easy management by operators. The software also,Report GeneratorSpectral operation tool can better calculateVarious forms of statistical reports can compare the differences between several sample spectra.

The fully automatic gas analyzer can be usedInstallation video of gas analyzerindependentGuide customers to install and debug gas chromatographs by themselves.

Gas analysis gas chromatograph completes the basic operations of the chromatograph in the following order

Gas composition analysis chromatographic method Performance characteristics:

technical advantage：With the new generation of high-performance and high stabilityGC-7900Based on gas chromatography, reliable and stable operationDing;

comprehensive strength：One injection solved the problems of hydrogen, oxygen, nitrogen, carbon monoxide, and carbon dioxideAlkanes and olefinsComplete analysis of gas; IncreaseThe FID detector can simultaneously detect the content of benzene, toluene, and xylene in coal gas.

core technology： adoptThrough central cutting technology, reverse blowing technology, and multi columnParallel series connectionTechnology, multi detectorparallel connectionThe application of cascade technology for full component analysis of coal gas, natural gas, liquefied gas, as well as feed gas and process gas in chemical production processes.

Operation ModeTen way valve injection is divided into two paths, one using hydrogen as the carrier gas and the other using nitrogen or argon as the carrier gas. Six way valve cutting technology ensuresCO2 does not flow into the molecular sieve chromatography column,avoidmolecular sievechromatographypillarCO2 poisoning；

Detection Application：Select oneOr two（TCD detector, if other hydrocarbon compounds need to be analyzed, FID detector can be added.Installing a flame photometric detector can analyze sulfur-containing compounds in coal gas.
