Use these steps for enhanced performance

Lee, S. H., Binkley, M. J., GTC Technology US, LLC

When designing distillation columns, engineers focus on selecting the required number of trays or packing height and column diameter to achieve target performance. As a result, distillation column feed condition is often overlooked. Improper feed design can hinder performance and influences unit economics. This article will illustrate useful distillation column feed design optimization methodologies. A case study is demonstrated in detail and highlights how optimum feed design enhances distillation column performance. Technical considerations for feed location. Selecting optimum feed location is critical to maximizing distillation column performance. Improper feed location of a distillat
