Abstract
A piece of equipment commonly used in many petrochemical and refinery processes is a pressure swing adsorption (PSA) unit. A PSA unit may be used to recover and purify hydrogen process streams, such as from hydrocracking and hydrotreating process streams. Aspects of the present disclosure are directed to monitoring PSA unit processes for potential and existing issues, providing alerts, and/or adjusting operating conditions to optimize PSA unit life. There are many process performance indicators that may be monitored including, but not limited to, flow rates, chemical analyzers, temperature, and/or pressure. In addition, valve operation may be monitored, including opening speed, closing speed, and performance. The system may adjust one or more operating characteristics to decrease the difference between the actual operating performance in the recent and the optimal operating performance.
