摘要
精馏塔再沸器是炼油、化工、轻工等行业中非常重要的换热设备,这种再沸器的优化和传热强化对热能的优化利用具有重要意义。本文运用经济学方法和传热强化技术,对以低温热为热源的再沸器进行优化设计,建立了同时考虑传热损、流动损和传热强化的再沸器经济优化目标函数和约束条件。并给出了应用实例。
Reboiler of fractionating column is an important type of heat exchangers in the refinery industry, chemical industry, light industry and so on. The optimization and heat transfer enhancement of the reboiler is very significant for the optimal utilization of thermal energy. In this paper, the reboiler with low-temperature heat source was optimized applying exergoeconomics and heat transfer enhancement techniques. An exergoeconomic model (including objective function and constraint equations) was established. In the objective function, heat transfer exergy dissipation, flow exergy dissipation and the heat transfer enhancement was considered simultaneously. A case study was given to illustrate the application of the model.
