- W1991111639 abstract "본 연구에서는 천연가스 처리공정 및 석유화학 공정의 Saturated gas plant에서 주로 사용되고 있는 탈에탄탑(Deethanizer)에 대한 설계 과정과 재비기의 heat duty를 최소화시킬 수 있는 원료 주입단의 위치를 최적화시켰다. 탈에탄탑의 공정 모사를 위해서 상용성 모사기인 Invensys사의 PRO/II with PROVISION을 사용하였으며, 열역학 모델식으로는 Soave가 변형시킨 Redlich-Kwong 상태방정식을 사용하였다. 본 연구를 통해서 분리를 위한 최소이론단수는 9.02단이며, 최소환류비는 0.62437이며, 최적의 이론단수는 20단이며, 최적의 원료 주입단은 9단이고 이때 재비기의 heat duty의 최소값은 $12.7470{times}10^6;KJ/hr$ 임을 알 수 있었다. 【In this study, we have completed the simulation and optimization work for the deethanizer column which was used for natural gas processing plant or saturated gas plant in a petrochemical process. An optimal feed stage location which minimizes the reboiler heat duty was determined. For the modeling of deethanizer, PRO/II with PROVISION was used and Soave modified Redlich-Kwong equation of state model was selected. Through this study, we have found that the minimum number of stage and minimum reflux ratio for separation were 9.03 and 0.62437, respectively and the theoretical stage number was 12, optimal feed stage location was 9 and minimum reboiler heat duty was $12.7470{times}10^6;KJ/hr$ .】" @default.
