Shortcut Method for Initialization of Dividing‐Wall Columns and Estimating Pareto‐Optimal <i>NQ</i> ‐Curves

Abstract In early project stages, often no simulation results are available for dividing‐wall columns. Hence, shortcut methods used to estimate suitable vapor and liquid splits. a previous paper, it was demonstrated that diagrams suited tool satisfy this need. However, has turned out shows weaknesses columns with finite or non‐optimal stages. This contribution closes gap presents an extended approach derive initial guesses. For purpose, the original diagram is combined heuristic calculate Pareto‐optimal column designs resulting in stage‐adapted diagram. A comparative study illustrates new powerful generate reliable guesses multiple simulations stage numbers.
