Advanced process control (APC) offers solutions to use full catalyst regenerator capacity safely and to generate substantial benefits. Significant yield increases and operating cost reductions can be ..
APC with inferential modeling was successfully applied to pygas hydrogenation units. The lengthening of the catalyst run length limits downtime for both the pygas unit and upstream units such as the steam cracker.
As the main sulfur source in the gasoline pool, fluid catalytic cracker (FCC) gasoline cuts must undergo severe hydrodesulfurization (HDS) processing to achieve ultra-low-sulfur gasoline (ULSG) pool s..
Applying advanced process control solutions enabled raising unit output without a major retrofit of existing equipment
