This month's Safety E-Book topic highlight is: Eliminating Hazards.
Three elements must be present for a flammable hazard to exist: fuel, oxygen, and a source of ignition. If any one of these elements is lacking, it is not possible to have a fire, which is why safety experts study ways to eliminate one of them.
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.
