FWKO 유수분리공정을 이용한 오일-물 혼합물의 분리특성
Characteristics of Water Separation for Oil-Water Mixture in a FWKO Vessel
오일-물 혼합물에서 물을 제거하기 위하여 FWKO(Free Water Knock Out) vessel에서의 물 분리특성에 대해 연구하였다. 오일을 모사하기 위해 데칸, 톨루엔, 아스팔트를 사용하였다. 데칸을 이용하여 프로토타입 vessel에서 기초실험을 수행하였으며, 기초실험결과를 토대로 최적 water cut이 0.8인 것을 알게 되었다. 이에 이어 톨루엔을 이용하여 성능평가를 실행한 결과로 최적 체류시간이 1,200 sec인 것을 알 수 있었고 아스팔트를 사용하여 방해판의 개수, 실험온도를 변수로 FWKO vessel에서의 최적의 물 분리조건에 대해 조사하였다. 최적의 분리조건은 방해판 3개, 온도 45 ℃ 였다.
Characteristics of water separation in a FWKO(Free Water Knock Out) vessel was investigated to remove water from oil-water mixture. Decane, toluene, and asphalt were used as model oils. Preliminary experiments were carried out for decane in a prototype FWKO vessel. Based on the results of preliminary experiments, the prototype vessel was modified and its performance was evaluated by using toluene. The effects of experimental variables on the separation of oil-water mixture were evaluated in terms of separation efficiency. The experimental variables include water cut(water ratio), number of baffles, residence times, and operation temperatures. The optimum conditions of water separation were found to be 0.8 water cut, 3 baffles, 1,200 sec, and 45℃ .
