Abstract

The cracking furnace is the core of an ethylene plant. An optimization method is built based on the integration of reaction network. Starting from atomic scope, an algebraic procedure is used to seek all possible reactions and establish the reaction network. Based on this, the reaction network is integrated and simplified to identify the variation rate of every component. The calculation procedure is developed to identify the variation of each component’s concentration and the selectivity and identify the optimal furnace parameters. For the studied furnace, the residence time corresponding to the minimum by-product production is identified to be 0.4 s, and its by-product generation is 4.3% less than that at the initial residence time (0.3 s).

基于反应网络集成的乙烷热裂解炉优化

摘要

裂化炉是乙烯装置的核心。建立了基于反应网络集成的优化方法。从原子范围开始，使用代数程序来寻找所有可能的反应并建立反应网络。基于此，反应网络被集成和简化以识别每个组件的变化率。开发了计算程序，以识别每种组分的浓度和选择性的变化，并确定最佳的熔炉参数。对于所研究的炉子，与最小副产物产量相对应的停留时间被确定为0.4 s，其副产物产生比初始停留时间（0.3 s）少4.3％。
