Flow simulations give refiner capacity, product-quality gains

During the past 5 years, Mobil has achieved tens of millions of dollars in capacity and product-quality gains by using computational fluid dynamics (CFD).Mobil has used CFD to improve performance of refinery process equipment such as reactors, separators, and extractors.Low-cost debottlenecking, a key initiative throughout the refining industry, usually involves simple process-hardware changes. These changes may improve fluid-flow patterns to enhance reaction rates, mixing, heat and mass transfer, phase contacting or segregation, and surface or interface renewal.CFD is the tool of choice for many refining problems. Experimental flow studies cannot always capture all of the relevant physic...
