Field Proven Solutions For High-Cycle Pressure Swing Adsorption Control Valves (FISHER)

Maximize yield with high purity of end products (99.99%) and bring down the OPEX on the valves scope along with a predictive maintenance strategy

Pressure Swing Adsorption (PSA) is a process that separates the impurities from the gas mixture to produce gas products such as hydrogen, oxygen, or nitrogen. PSA is typically available in Refineries, Petrochemical (PDH), Air Separation Units (ASU), ethylene plants, and ethanol production facilities. The gas separation takes place through a series of fixed bed absorbers with forward and reverses 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 increase the maintenance cost needed for common failures such as shaft breakage, poor valve-actuator-positioner linkages, and valve leaking issue.


What's your opportunity?

·         Maximize PSA productivity and gas product purity with minimum maintenance needs on the control valves

·         Predictive Maintenance by using Smart Positioner (linkage-less design) which has Performance Diagnostic features to carry out time-series online monitoring of valve health and performance
