PEG가 함유된 폴리이미드 막 제조와 투과증발을 이용한 방향족/지방족 혼합물의 분리 |
| 초록 |
Separation of aromatic/aliphatic hydrocarbons is one of the most challenging processes in the petrochemical industry. Poly (ethylene-glycol)-containing copolyimides were synthesized using one dianhydride and two diamines by chemical imidization. Pervaporation experiments for the investigation of the performance of the membrane were conducted at various temperature with aromatic/aliphatic mixtures as feed streams. Experimental results showed that total flux increases with increasing of benzene concentration. Introduction of PEG units in the polymer generally showed very high hydrocarbon permeability than another polymer membrane without PEG segment, but this polymer also caused a decrease of enrichment factor. Total flux was increased and enrichment factor of benzene was decreased with increasing temperature. |
