基于曲线生成器的间歇萃取精馏分离R410a操作优化
Operational optimization of batch extractive distillation for R410a based on profile generator
摘要
Abstract
Enabling refrigerant recycling is an effective strategy for reducing carbon emissions throughout the refrig-erant lifecycle.The characteristics of wide distribution,large compositional variation,and unstable recovery amount of waste refrigerants make batch extraction distillation more advantageous.To address the issues of strong stiffness and time-consuming computation in the differential-algebraic model of batch extractive distillation,this paper inno-vatively proposes an optimization scheme that parametrizes the operating curves using a curve generator and solves them with the Bayesian optimization algorithm(BO).The effectiveness of the scheme was verified through the sep-aration of R410a.Case results show that at least two generated curves are required to describe a complete batch ex-tractive distillation process.Compared to stochastic optimization algorithms,BO provides better reproducibility and orders of magnitude reduction in objective function evaluations,significantly lowering computational costs.关键词
