How about using a compression process to concentrate the exhaust gas? !
Thread Content
Most current waste gas concentration processes use adsorption methods; so, can compression methods be used for concentration as well? From a process perspective, the process becomes simpler, the workflow is shortened, the number of equipment and pipelines decreases, as does the amount of utility needs, resulting in reduced investment. From the perspective of the equipment, it becomes a pressure vessel, which increases the requirements for that equipment and raises its cost. Additionally, it is also a question whether some of the substances used in subsequent processes can withstand high pressure. Has anyone worked with the compression + RTO process? Discussion is welcome!
I’ve never seen a process for compressing mixed gases; could there be issues such as deflagration or corrosion?
A mixed gas doesn’t count, as 99% of the components in exhaust gases are air. Deflagration is even less likely to occur; there is little change in temperature, and no source of fire is present.

Oil and gas exhaust gases should be manageable, but corrosive exhaust gases present more challenges; for example, sulfur dioxide-containing exhaust gases – can they be used as a substitute for conventional desulfurization methods?
I didn’t make it clear; I’m mainly referring to organic waste gases, as they are basically concentrated before entering the RTO (combustion system). However, the investment for adsorption concentration is relatively high, and the process is also lengthy. Compression can also concentrate things. But I’ve never seen anyone do that. That’s why I had this idea. Furthermore, corrosion is not a particularly difficult issue; what’s required is a higher quality of material, because even at normal pressure, corrosion can still occur.
