Raw gas analysis
Thread Content
Currently, the company purchases a large volume of raw gas from external sources (mainly C3 and C4), around 1,000 trucks per month. The refinery gas analysis we use now has an operation time of around 11 minutes. I was wondering if there is a more convenient and faster way to determine it? Such as gas mixing injection analysis, etc

Do you need to separate the sample components before analysis? For LPG analysis, sampling is generally carried out while the cylinder is under pressure, and it must be done in accordance with the relevant sampling standards. If the material arrives in liquid form, a liquid sample is taken; if it arrives as a compressed gas, then a gas sample taken under pressure is used. The analytical method is generally chromatography, and sample injection in chromatography also requires careful attention. For liquid samples, it is necessary to completely vaporize a certain amount of the liquid sample before injection, or use pressure-driven liquid injection (carbon 3 may not work for this).
11 points is sufficient; for this case, you need to add gas sampling from a flash evaporator. Agilent refinery gas?
