Abstract

In this study, the simulation was performed for the CO removal process using a composite membrane in DME production. The composite membrane, PEI-PDMS (polyetherimide- polydimethyl siloxane) manufactured by Airrane Co. Ltd., was used in the modeling through a commercial simulation design program, PRO/II with PROVISION 9.2 by Invensys. To simulate the process, the permeability constants of each of the pure component from Airrane Co. Ltd. were determined by regression analysis from the experimental data. The required separation membrane area and utility cost in the CO removal process were obtained using a chemical process simulator and composite membrane with a compatible permeability constant.

본 연구에서는 디메틸에테르(dimethyl ether) 생산 공정에 포함된 이산화탄소 제거공정에서 이산화탄소 제거 방법으로 복합막(composite membrane)을 사용하는 공정에 대해 공정구성과 모사를 수행하였다. 복합막은 (주)에어레인에서 제조한 PEI-PDMS(polyetherimide-polydimethyl siloxane) 복합막을 대상으로 하였으며 복합막 공정을 모델링하기 위해서 상용성 화학공정 모사기인 Invensys 사의 PRO/II with PROVISION 9.2를 사용하였다. 그리고 복합막 공정을 모사하기 위해 필요한 각 순수성분들의 투과도 상수는 (주)에어레인에서 수행한 실험 데이터를 회귀분석 하여 새롭게 결정 하였다. 결국 실험을 통해 얻은 투과도 상수와 상용성 화학공정 모사기를 활용하여 이산화탄소를 제거하기 위한 복합막 공정을 구성하고 제거에 필요한 분리막 면적과 Utility 비용을 도출하였다.
