Embedding equation oriented models of process unit operations in a sequential modular flowsheet simulator: Study with a gas separation membrane model

Within the Dow Chemical Company the strategy is to centre process flowsheet design activities around the simulation tool Aspen Plus (from Aspen Tech Inc.). However, the model library of Aspen Plus is limited in type and number of models of process unit operations. Equation oriented modelling tools, such as gPROMS (from Process Systems Enterprise...
