Stefano Stefano   39-08-02 00:00 연구내용으로 추정해 볼때.. computor-aided와 simulation 사이에 "steady state"가 들어가야 정확할 것 같다는 생각이고, 또, 맨 끝줄에 Aspen Plus 12.1 과 were 사이에 "distillation modules"가 들어가야 맞을 것 같고.. 그렇지 않으면 were를 was로 고쳐야 되겠습니다. 연구내용으로 추정해 볼때.. computor-aided와 simulation 사이에 "steady state"가 들어가야 정확할 것 같다는 생각이고, 또, 맨 끝줄에 Aspen Plus 12.1 과 were 사이에 "distillation modules"가 들어가야 맞을 것 같고.. 그렇지 않으면 were를 was로 고쳐야 되겠습니다.

Stefano Stefano   39-08-02 00:00 질문이 아주 다양합니다 그려.  대충 써본 것인데 이를 조금 매끄럽게 다듬어 보세요. In this work, a computor-aided simulation was made for the separation of 99.9 w% fuel-grade dimethylether(DME) applicable as one of diesel substitutes. The unit is to separate DME from the reaction mixture and consists of DME absorber, CO2 stripper, DME product column and a solvent recovery column. DME is absorbed in the methanol used as an absorbant, CO2 is stipped off from the methanol, 50 kg/d of 99.5 w% DME is splitted from the product column and methanol is recovered and recycled from the solvent recovery column.    For the simulation NRTL model was used, which is one of models that employ activity parameters in liquid phases and Henry＇s law was introduced assitantly to make allowance for the dissolution of gaseous components in water and methanol. Aspen Plus 12.1 were utilized for all the simulation.  질문이 아주 다양합니다 그려. 대충 써본 것인데 이를 조금 매끄럽게 다듬어 보세요.
