基于ProMax的高含硫天然气脱硫装置模拟与优化

Simulation and optimization of sweetening unit for high-sour natural gas based on ProMax

采用ProMax中Amine Sweetening-PR物性模型对万州净化厂脱硫装置进行建模,模拟原料气气质变化及胺液循环量、胺液质量分数等操作参数变化时净化情况。采用spss以净化效果和能耗为目标函数,制定了9因素3水平正交试验表,并对正交实验结果进行极差和方差分析,找出各因素对原料气净化及能耗的影响强弱,并提出净化效果最优运行方案。

Amine Sweetening-PR physical property model in ProMax is used to build a model for the gas sweetening unit of Wanzhou Purification Plant,which is used to simulate the purification situation of natural gas when operation parameters including the composition of crude natural gas,temperament,the circulation amount and concentration of amine solution are varied. Taking the purification effect and energy consumption as objective functions,a 9-factor 3 horizontal orthogonal test table based on spss software is also developed and the results of orthogonal test are analyzed by comparing the range and variance.Therefore the influences of various factors can be concluded and the optimal operating scheme is proposed.
