BKOAI implemented advanced process control improvements and automated valve reset logic to successfully increase the utilization, stability, and reliability of a pressure swing absorber unit.
Goals
Increase the overall utilization rate of the pressure swing absorber unit.
Enhance process control stability during standard and transitional operations.
Minimize operational limitations that restrict daily absorption capacity.
Establish a reliable foundation for continuous and stable gas separation.
Challenges
Control limitations constrained the pressure swing absorber from reaching full operational utilization.
Suboptimal control behavior caused performance bottlenecks during crucial operating transitions.
Outdated split-range logic created unnecessary restrictions on system responsiveness and stability.
Manual or inefficient valve reset procedures delayed recovery during unexpected unit trips.
Solutions
Implemented advanced process control improvements to stabilize the absorber unit.
Adjusted control loop tuning to optimize overall system responsiveness and stability.
Modified split-range logic to eliminate existing operating constraints during transitions.
Programmed automatic valve reset logic to streamline recovery during unit trips.
Results
Achieved higher pressure swing absorber utilization rates across all operational phases.
Demonstrated significant improvements in loop control stability under diverse conditions.
Secured more reliable operating performance during critical unit transitions.
Reduced process variability and unexpected downtime caused by valve reset delays.
