Gas chromatograph for full component analysis of coke oven gas (water gas, semi water gas, blast furnace gas)

Instrument introduction and method description:

Method description:

利用Gas chromatograph,2aTCDDetector,2An imported automatic ten way valve,1Imported automatic six way valve, dual carrier gas of high-purity hydrogen and nitrogen, capable of fully automatic analysis of coke oven gas with a single injectionH2TheO2（Ar）TheN2TheCH4TheCOTheCO2TheCnHmAll components.

Technical features:

1. Due to the configuration of an automatic ten way valve for reverse blowing, the sample gas containsH20SulfidesC3The above recombinant components have been backblown and emptied, greatly extending the service life of the molecular sieve chromatography column and reducing the number of aging cycles（6Aging once a month.

2. Each automatic valve is equipped with a sample filter in front, which can reduce the damage of dust in the gas to the valve and extend its service life.

3. Due to the use of dual carrier gases of hydrogen and nitrogen,H2Accurate, stable, and reliable measurement along the way. Used for measuringH2Used along the wayN2As a carrier gas, it has high stability and accurate results; Used for measuringO2TheN2Waiting all the way to useH2As a carrier gas, the thermal conductivity bridge flow is high, which improves the accuracy ofO2TheN2TheCH4TheCOTheCO2Waiting for the sensitivity of the detection.

4. Hydrogen gas is detected separately on a separate route, avoiding errors caused by subtraction in hydrogen gas content. The hydrogen gas detection results are consistent with the results of the Austrian analyzer analysis.

5. Three valves and five columns are methods for analyzing gas components.
