Seeking help for negative pressure sampling
Thread Content
The unit is equipped with a one-stage reactor; the main components in the reaction are gas, hydrocarbons, CO, H2, N2, O2, tar water, and a small amount of H2S. The absolute pressure is 1.5 kPa. The reactions that take place inside are quite complex, and the temperature range is wide, ranging from several dozen degrees to several hundred degrees, or even up to 1,000 degrees Celsius. With this concept, it is possible to take samples (gas samples) at different temperature points during the reaction process. May I ask, is it possible to do that?

Or perhaps the experts can discuss whether this is possible to achieve. .
It’s difficult with such high temperatures; it’s the negative pressure sampling that poses a problem.
Reply to 3# fxswl: Yeah, indeed. High temperature is a big problem. . But still, there is a glimmer of hope. . . Looking forward to everyone's contributions
Sampling at high temperatures: samples at several hundred degrees can cause burns even when a cooler is used. To what extent can such high temperatures be reduced using a cooler? The sampling speed under negative pressure is already slower than that under positive pressure; moreover, at high temperatures the volume of the sample decreases after it is taken out, and it may also contain a lot of moisture.
It seems this issue was discussed on the forum before; dual-valve control for sampling should suffice
