반응증류공정을 이용한 디메틸 에테르 생산
Dimethyl Ether Production using a Reactive Distillation Process
디메틸 에테르 생산을 위한 반응증류공정을 제안하였다. 디메틸 에테르 생산을 위한 기존공정은 하나의 반응기와 두 개의 증류탑으로 구성되어 있고, 반응-증류혼성공정 [6]은 하나의 반응기와 하나의 증류탑으로 구성되어 있다. 본 연구에서 제안한 반응증류공정은 액상반응으로 하나의 장치에서 반응과 증류가 동시에 일어나는 공정으로 기상반응인 다른 두 공정과 에너지 및 장치비를 비교하였고, 다른 공정들보다 반응증류공정에 큰 장점이 있다는 것을 보였다. 또한 반응증류공정의 설계 및 조업변수들이 공정의 성능에 미치는 영향을 조사, 분석하여 공정 설계지침을 제공하였다.
In this study, we propose a reactive distillation process for production of dimethyl ether (DME). The conventional process for the production of DME consists of one reactor and two distillation columns. The reaction-distillation hybrid process for the production of DME [6] is an interlinked system between one reactor and one distillation column. The newly proposed process for the production of DME is a reactive distillation column in which the reaction and separation occurs simultaneously and the reaction takes place on liquid phase only. This characteristics of the reactive distillation process bring about great benefits. Comparison between these three processes shows a great advantage of the proposed one over the other two processes in the reduction of energy and capital cost. We examine and analyze the effect of design and operation variables on the performance of the proposed process and provide design guides for the process.
