초록

최근 폐 탄약의 회수를 통한 고에너지 물질의 재활용 및 재사용에 대한 연구가 선진국을 중심으로 활발히 진행되고 있다. 본 연구에서는 재활용 기술응용의 일환으로, 폐 탄약 처리 중 나오는 TNT와 RDX 혼합물을 모사이동층(SMB) 공정을 통해 효율적으로 분리하는 실험과 이에 대한 동적 모사를 수행하였다. SMB 공정의 운전 영역을 설정하기 위하여 혼합용액의 유속 변화에 따른 각 물질의 체류시간을 HPLC로 측정하였으며, 모멘트 모델을 이용하여 흡착 컬럼에서 각 물질의 흡착평형을 분석하였다. 흡착 평형과 SMB 운전 삼각법을 통하여 4개의 운전 영역을 결정하였다. 결정된 운전 영역에서 아세토나이트릴과 물이 6:4와 1:1로 구성된 2가지 용매에 대해 SMB 공정을 이용한 분리 실험을 수행하였다. SMB 공정의 운전 조건 변화에 따른 순도, 회수율, 생산성, 용매소비량 등의 4가지 성능 지수를 평가하였다. 또한 SMB 공정에 대한 수학적 모델을 통하여 공정의 동적 모사를 수행하여 실험의 결과와 비교하였다. SMB 공정을 통해 100% 순도의 TNT와 RDX를 얻을 수 있었으며, 동적 모사 결과는 실험 결과와 잘 일치하여 공정 동적 거동 예측과 공정 설계에 적용할 수 있음을 인하였다.

Currently, researches on recycling and reuse of waste energetic materials have recently gained a great attention from advanced countries due to ever tightening environmental regulations. In this study, as a part of a recycling technology, the experiments and dynamic simulation of simulated moving bed (SMB) process were performed to efficiently separate TNT and RDX from their mixture, which are main components of ammunition. In order to determine the operation zone of SMB process, the retention times of TNT and RDX were measured using HPLC at different flow rates and the adsorption equilibrium of each component was obtained by using a moment method. According to the adsorption equilibrium and the triangle theory of SMB process, four operation points were determined and separation experiments were carried out by the SMB process using the solvent consisting of acetonitrile and water. Two different mixing ratios (6:4 and 1:1) of acetonitrile and water were chosen for the experiment due to the great impact of mixing ratio of the solvent on separation. The performance of SMB process was evaluated by purity, recovery, productivity and solvent consumption. Pure TNT and RDX were successfully obtained from the SMB process and the dynamic simulation for the SMB process agreed well with the experimental results. Therefore, the dynamic model could be applied for predicting the dynamic behavior of the SMB process and designing a large scale SMB process.
