Moderator, we have 0.03% hydrogen sulfide gas, 0.006% carbonyl sulfide, 23% CO, 0.2% O2, 60% CO, 0.06% CH4, and 30% H2. If an accurate analysis is required, please provide a corresponding analysis plan.
Use austenite with 1.2% oxygen – why?
Moderator, we have hydrogen sulfide at 0.03%, carbonyl sulfide at 0.006%, CO at 23%, O2 at 0.2%, CO at 60%, CH4 at 0.06%, and H2 at 30% – the proportions can be adjusted as needed
This is syngas or a mixed gas obtained through the coal gasification process. The original poster said accuracy is required – but to what extent? Especially for several components with low concentrations, to what degree of accuracy is required? This has a lot to do with choosing the analysis methods and instruments.
Gas chromatography, FPD+TCD dual detectors, 1 ten-way valve, 2 six-way valves.
