Hydrocracker Control Consulting

Hydrocrackers are one of oil refining's most demanding process control challenges at all levels -- safety systems, regulatory control and advanced control. Economically, hydrocrackers are well situated in today's market, converting heavy oils and inexpensive natural gas into high-value fuels. Yet, most hydrocrackers in industry are under-automated, lacking basic excursion control, depressure prevention, and effective advanced control features.

Read "Update hydrocracker controls for reliability" in Hydrocarbon Processing Journal, Oct. 2012 issue.

The message that often fails to accompany auto-depressure projects is the need for much better excursion control to avoid reaching auto-depressure conditions in the first place.  Auto-quench is a DCS control, but it can be one of the most important control functions in a refinery, since it is the final layer of hydrocracking reactor depressure prevention.

These are controls that work for us, not the other way around.

Operating a highly exothermic reaction vessel, without reliable bed outlet temperature controls and other safeguards, no longer makes common sense, and should no longer pass a modern process hazard analysis (PHA).  Contact APC Performance to discuss modern best practice hydrocracker controls.
