A shortcut design method for complex distillation structures

Distillation is by far the most common fluid separation method in chemical industry, and its design routinely conducted using commercial software, often based on initial shortcut calculations. Whilst simulation optimisation of simple distillation systems are fairly straightforward, more complex structures, such as dividing wall columns (DWC), can prove problematic due to failure initialise or converge, no adequate methods exists for these structures. In this work, a novel presented which solve problem simultaneously also structures procedure without need iterative manual The illustrated four case studies. variables obtained be used rigorous problems, thus greatly reducing risk initialisation convergence issues, very
