Maximize yield with high purity of end products (99.99%) and bring down the OPEX on the valves scope along with predictive maintenance strategy
Pressure Swing Adsorption (PSA) is a process that separates the impurities from gas mixture to produce gas product such as hydrogen, oxygen, or nitrogen. The gas separation takes place through a series of fixed bed absorbers with forward and reverse flows to switch the gases between parallel vessels by control valves. One of the biggest challenges for control valves in PSA is that they are expected to cycle as often as every few minutes while providing tight, bi-directional shut-off. Failure of control valves can directly affect gas separation and product purity, as well as increasing the maintenance cost needed for common failures such as shaft breakage, poor valve-actuator-positioner linkages, and valve leaking issue.
