Optimal Design of Extractive Dividing-Wall Column Using an Improved Sequential Least Squares Programming Algorithm

Extractive dividing wall column (EDWC) is an efficient and economic technique for separating azeotropic or close boiling-point mixtures. However, optimal design of EDWC using rigorous models is still challenging. In this work, we develop an improved sequential least squares programming (SLSQP)-based...

Popis
Shrnutí:Extractive dividing wall column (EDWC) is an efficient and economic technique for separating azeotropic or close boiling-point mixtures. However, optimal design of EDWC using rigorous models is still challenging. In this work, we develop an improved sequential least squares programming (SLSQP)-based feasible path algorithm for such optimal design. The computational results show that the proposed algorithm can generate better solutions and reduce the computational time by around one order of magnitude.
