Simultaneous Optimization and Heat Integration Framework Based on Rigorous Process Simulations

摘要: This paper introduces a novel simultaneous optimization and heat integration approach, which can be used directly with the rigorous models in process simulators. In this overall is optimized utilizing external derivative-free optimizers, interact simulation. The subproblem formulated as an LP model solved simultaneously during of flowsheet to update minimum utility exchanger area targets. A piecewise linear approximation for composite curve applied obtain more accurate results. describes application approach three cases: recycle process, separation power plant carbon capture. case study results indicate that relatively easy implement achieves higher profit lower operational cost and, example, net efficiency than sequential approach.
