Pressure swing adsorption nitrogen production
Thread Content
There are many technologies for producing nitrogen using air pressure swing adsorption, but I would like to ask if anyone knows, or if there is anyone with experience, in how to adsorb and recycle the nitrogen from exhaust gas (99% nitrogen, a small amount of oxygen, non-condensable gases, and toluene).
Your question is not detailed enough; first, it is necessary to determine exactly what the components of the feed gas are What purity of nitrogen do you need? Also, where is the purified nitrogen used, and what substances need to be removed? Nitrogen with a purity of 99% can be separated easily; if the requirements are not high, physical methods are sufficient for separation!
