Abstract

Retrofit and optimization of low-temperature gas separation processes is a challenging task owing to complicated interactions between the core process (separation columns), refrigeration cycles, and the associated heat exchanger network. In this paper, the performance of cold section of an olefin plant is optimized. A comprehensive screening of all effective changes using genetic algorithm suggests some retrofit modifications. Having incorporated the best operating column parameters along with available refrigeration levels, a 11.3% improvement in utility cost was achieved.
某烯烃装置低温气分离段改造
由于核心工艺(分离塔)、制冷循环和相关热交换器网络之间复杂的相互作用,低温气体分离工艺的改造和优化是一项具有挑战性的任务。本文对某烯烃装置冷段的性能进行了优化。使用遗传算法对所有有效变化进行全面筛选,建议进行一些改进修改。结合了最佳的操作塔参数以及可用的制冷水平,实现了11.3%的公用事业成本改善。
