Jiedao IslandGC1690Main features of refinery gas analysis gas chromatograph:

1、 Analysis of refinery gas
With the development of refining technology and the improvement of processing depth, the production of a large amount of by-product gas, namely refinery gas, during crude oil processing has also increased. The comprehensive utilization of refinery gas has become an important link in improving the economic efficiency of refineries. *Refinery gas is a valuable raw material for the production of petrochemical products, and understanding its composition is a prerequisite for comprehensive utilization. Therefore, establishing and improving analytical methods for refinery gas is of great significance. The main components of refinery gas include hydrogen gas,C1~C5Alkanes,C2~C4Olefins and small amountsC5Alkanes, alkenes, and some impurities such asH2S、CO、CO2,Dienes and small amounts of alkynes may also be produced in some special processing procedures. With the rapid development of gas chromatography, its role in the analysis of refinery gas components has become increasingly evident.
2、 Analysis of Gas
Natural gas, liquefied gas, and coal gas (including artificial gas, coke oven gas, blast furnace gas, converter gas, water gas, semi water gas, etc.) are gases closely related to people's production and life, widely used in fields such as *, petrochemicals, metallurgy, and fine chemicals. Therefore, the calculation of its content (especially calorific value) is still important. Gas chromatography provides a solution that relies on chromatographic columns to separate complex components and uses high-sensitivity detectors for quantification. Within a few minutes, the content (calorific value) can be accurately calculated.
