Abstract

디메틸에테르 생산을 위한 새로운 반응-증류 혼성공정을 제안하였다. 디메틸에테르 생산을 위한 기존공정은 하나의 반응기와 두 증류탑으로 구성되어 있다. 본 연구에서 제안한 반응-증류 혼성공정은 각각 하나의 반응기와 증류탑이 통합된 공정이다. 제안된 신공정을 에너지 및 장치비 면에서 비교하였고 에너지 면에서 기존공정보다 반응-증류 혼성공정에 큰 장점이 있다는 것을 보였다. 또한 반응-증류 혼성공정의 설계 및 조업변수들이 공정의 성능에 미치는 영향을 조사, 분석하여 공정을 최적화하였다.

In this study, we propose a new reaction-distillation hybrid process for production of dimethyl ether (DME). The conventional process for the production DME consists of one reactor and two distillation columns. The proposed reaction-distillation hybrid process is an interlinked system between one reactor and one distillation column. Comparison between these two processes shows a great advantage of the proposed one over the conventional one in energy saving. We examine and analyze the effect of design and operation variables on the performance of the proposed process and optimize the process.
