Pressure swing adsorption (PSA) is a widely used technology for the purification of gases. A system of vessels is used to alternate between adsorbent filled vessels, one vessel being on line and removing moisture at high pressure, and the other off line releasing the trapped moisture at low pressure, to thoroughly dry a gas.
PPM measurement at the outlet of the oxidizer ensures that it does not exceed emission levels. In addition, by monitoring at the inlet and outlet of the oxidizer hydrocarbons can be measured and compared before and after processing, indicating efficiency.
For the next few weeks we're going to deep dive into our Chemical E-Book, our first topic is: Ovens & Dryers.
Many chemical processes involve coating a product with a flammable solvent or mixture of solvents and then run through an oven to dry the solvents. At this point an explosive level of vapors is possible and needs to be monitored.
