You’ll find much more to the story, such as all the controlled, manipulated, constraint and disturbance variables that were included in the model predictive controller. In an earlier post, Optimizing Delayed Coker Operations with […]

Crude oil is processed into gasoline, diesel fuel, jet fuel, lubricating oils and waxes, leaving some residual crude that usually undergoes additional processing. The crude residue […]
