Abstract

Simulated moving bed (SMB) process is a continuous chromatographic technology used to separate a large amount of petrochemicals, fine chemicals, pharmaceuticals, and so on, drawing a great attraction of related industries. With the recent development of biotechnology, the SMB process has been adopted for the separation of various useful bio-products. Attempts to understand the separation mechanism of the SMB process in many aspects are reported in many publications. These researches have dealt with the improvement of SMB for easier operation and solving problem in process. The feed mixture fed into the SMB process may be of different concentration batch by batch rather than in uniform concentration. Retention behaviors of feed (psicose (A) and fructose (B) mixture) existing in the SMB unit in dynamic steady-state and feed (psicose (C) and fructose (D) mixture) newly injected into the SMB were analyzed. It was observed that the existing components, (A) and (B), were eluted relatively faster as the injection time of new feed was earlier during the port-switching period. In addition, the components (C) and (D) were eluted earlier as fresh feed was injected earlier in a port-switching time.

SMB 공정은 석유화학, 정밀화학, 제약 제품들을 연속대량으로 정제할 수 있는 크로마토그래피 기술로서 관련 산업에서 많은 관심을 얻고 있다. 최근 생명공학 기술의 발달과 함께, 다양한 생물 유래의 유용물질에 대한 SMB 공정의 적용이 시도되어 보고되고 있다. 또한, 다양한 방법으로 SMB 공정의 분리 메커니즘을 이해하는 연구들이 보고 되었다. 이와 같은 연구에서는 목적산물을 생산하는 일련의 생산과정에서 SMB 공정의 조업을 보다 용이하게 하고, SMB 공정에서 발생할 수 있는 문제의 원인을 분석하고 있다. 이번 연구에서는 정상상태에 이른 SMB 공정에서 기주입된 시료(psicose (A) 및 fructose (B) 혼합물)와 새로이 주입되는 시료(psicose (C) 및 fructose (D) 혼합물)의 체류 특성을 알아보는 모사실험을 수행하였다. 새로운 원료의 주입시점이 하나의 교환시간 중 앞부분일수록 기주입된 물질은 보다 빠르게 SMB 공정에서 유출되는 것을 확인할 수 있었다. 마찬가지로, 새로이 주입되는 물질들도 이와 마찬가지로 교환시간의 전반부에 주입될수록 보다 빨리 정상상태에 도달하는 것을 확인하였다.
