摘要
Abstract
The process of flare gas recovery encompasses an interdisciplinary spectrum,incorporating elements of energy,economics,and environmental studies.Based on the inherent methodologies of these disciplines,different disciplines have different focus points,objectives and evaluation indicators;there are contradictions among the objectives pursued by different disciplines,and incommensurability among the indicators provided by different disciplines due to different meanings and units.This brings difficulties to the quantitative analysis of multi-objective optimization for selecting flare gas recovery methods,yet there are few in-depth studies in existing literature on this aspect.The strategy for balancing the contradictions among the objectives and resolving the incommensurability among indicators based on the monetary form was discussed,it was proposed that the objectives and indicators be further transformed into a uniform monetary form.Therefore,a multi-objective optimization calculation method was developed which transformed the balance of contradictions among multiple objectives and the resolution of incommensurability among indicators into the analysis of the objective function value.Taking the optimization problem for FGR method selecting under varying flare gas emission volumes in a petrochemical enterprise as an example,the strategy and method were applied for quantitative calculation and analysis,and then the optimal solutions corresponding to different flare gas volume were obtained.The analysis showed that the strategy and method had objective,intuitive characteristics and were highly rational.Analysis also showed that the flare gas emission volume and initial investment of recovery system had a significant impact on the optimization for selecting recovery methods.关键词
