Eliminate mechanical seal failure in a crude distillation unit
Multiple mechanical seal failures in a crude distillation unit (CDU) resulted in total losses of $3 MM in a refinery since its startup in January 2015. The maximum seal life achieved did not exceed 6 mos, which was much shorter than the American Petroleum Institute (API) 682 “Advancements in Mechanical Sealing” goal of 3 yr of seal life.

Improve removal of phenolic and amine compounds in a sour water stripper
Joint stripping in a refinery sour water stripper (SWS) unit contributes to the concentration of phenols and total nitrogen (N) in the discharged treated water from the wastewater treatment unit.
Optimize a refinery H2 network using spreadsheet tools
One of the major goals in every refining complex is to minimize the utilization of its hydrogen (H<sub>2</sub>) generation units by maximizing the H<sub>2</sub> recovery from residual streams.
S.Korea's GS Caltex says unsure when will restart fire-hit hydrocracker, aromatics unit
SEOUL (Reuters) — GS Caltex, South Korea’s second-largest oil refiner, said on Monday that it was unsure when it would be able to restart a hydrocracker and aromatics unit after they were hit by fire last month.
The lost art of proportional band, and the accidental art of performance monitoring
Most control engineers know that proportional band and controller gain are largely interchangeable terms—both terms refer to the proportional setting of a proportional-integral-derivative (PID) controller and are commonly used by control system manufacturers.
