| Abstract: | The paper discusses the possibility of removing depentanizer from Gas processing Unit according to its status and function in the refinery.Steady state simulation technique based on non equilibrium rigorous mechanism models,softsensor technique based on statistic models and dynamic simulation techniques are used in the analysis.Detailed and quantitative analysis of comprehensive economic benefits of removing depentanizer is given.The average benefits per year are suggested to be about $18?500.However,influence by different feed C5 concentration on the benefits can not be omitted.Furthermore,the papers discusses the changes of operational parameters after removing depentanizer,including C5 and MTBE separation characteristics,MEOH and C4 azeotropic characteristics and the infulence of the setpoint of sensitive stage on product components. |
