Distillation Research and Development is moving rapidly with the utilization of computational fluid dynamic (CFD) modeling. Previously, a potential fractionation application would first be developed and fabricated. Then many hours of pilot plant testing would be required to finalize the design. The time line for the development of new distillation equipment has been reduced, leading to advances in fractionation equipment.Current applications of trays, packings, distributors and feed inlets can be optimized utilizing CFD modeling. CFD Modeling has improved the current generation of fractionation equipment. This modeling is also particularly important in maximizing capacity in tower revamps where the diameter of the tower is fixed. This paper will review the current‐generation fractionation equipment and the utilization of the same in the petroleum refining industry.
