초록

벤젠이 흡착질인 흡착공정에서 질소에 혼합된 수증기를 사용하여 탈착하는 방법을 사용할 때 탈착단계의 조업변수 영향을 실험적으로 살펴보았다. 탈착단계가 끝난 뒤 수증기를 제거하기 위한 건조단계의 유무가 흡착제의 재생효과에 어떻게 작용하는지 확인하였다. 흡착제 재생후의 파과곡선을 관찰함으로써 건조단계에서 건조시간의 변화에 따라 흡착제의 재생결과가 어떻게 달라지는지를 알아보았다. 수증기 탈착단계에서는 탈착시 혼합가스의 질소가스량이 고정된 상태에서 수증기량의 증가함에 따라 흡착제의 재생효율이 좋음을 볼 수 있었다. 그러나 질소 가스량이 커지게 되면 수증기 효과는 줄어들었다. 따라서 질소의 양과ㅏ 수증기 양을 경제적인 관점에서 비교하면서 최적의 수증기양을 예측하는 것이 가능할 것이다.

The operating variables of a desorption step were experimentally investigated tor the cycle of the process made up of benzene adsorption, steam desorption, and drying step. The effect of adsorbent regeneration depending on existence and nonexistence of drying step was studied by breakthrough curves obtained in the adsorption step of the second cycle. The duration of drying step was determined by the experimental results. In case that the amount of nitrogen gas was fixed, the regeneration efficiency increased with the amount of steam. However, the effect of steam decreased as the amount of nitrogen increased. Therefore, it would be possible to predict the optimum amount of steam comparing the amount of nitrogen gas with amount of steam in economic view.
