REFINE BEFORE YOU REBUILD: HOW SIMULATION KEEPS REFINERS AHEAD OF DISRUPTION

Global refinery crude runs are expected to average 81.7 mb/d in 2026, down 2.3 mb/d from last year. This executive brief maps what is driving the decline and where simulation gives refining engineers the edge.

Refinery closures in the U.S. and Europe, crude mismatch, record U.S. biofuel mandates, and ongoing disruption to Middle East supply are reshaping the refining landscape. Meanwhile, new capacity in China and India is shifting where refining happens. Engineers are being asked to do more with existing assets while evaluating entirely new feedstocks.

For decades, refining engineers have relied on CHEMCAD process simulation and Datacor’s hydraulic modeling tools to handle exactly these conditions. That is why we put together this executive brief covering:

  • Global refining trends across the U.S., Europe, Asia-Pacific, and the Middle East

  • Distillation unit optimization and energy efficiency gains using CHEMCAD

  • How process simulation diagnosed yield loss in a crude unit main column

  • Surge and cavitation mitigation using Fathom and Impulse during the KNPC Clean Fuels Project expansion

  • Transient modeling to choose the right surge protection for a pipeline segment

  • Using simulation to evaluate alternative feedstocks such as pyrolytic oil before capital is committed
