Abstract
The stagewise collocation method is applied to reduce the full-order m odels used for simulating multistage separation units. In particular w e refer to steady-state, high-purity (x(D) up to 0.9999) and symmetric (x(B) = 1 - x(D)) binary distillation columns. The performance of the se reduced-order models is represented in a master plot which provides , rather synthetically, the model error as a function of the reduction order.
