분리공정II 설계 프로젝트 A++받은 보고서입니다.
물과 메탄올 혼합물의 흡착 탈수공정을 TSA방식과 유사하게 설계해 보았습니다.
많은 도움 되실거라 믿습니다.
노력하여 열심히 한 만큼 얻는것도 많으실거라 예상됩니다.
좋은점수 받으세요 |

I. 서론
본 보고서에서는 연구/실험용 또는 반도체제조 등에 사용되는 초고순도의 메탄올을 제조하기위한 공정을 학부생이 할 수 있는 범위 내에서 계산을 통하여 설계해 보았다.
공정의 주목적은 99.88%의 고순도 메탄올을 99.995%의 초고순도 메탄올로 탈수시키는 것이다. 메탄올을 탈수시키기 위해 수분흡착능이 뛰어난 Molecular sieve 3A(Zeolite 3A)를 사용하였고, 생산효율을 높이기 위해 흡착과 탈착이 동시에 진행되는 온도교대흡착(Temperature swing adsorption)공정을 참고하였다. 흡착시간은 24시간으로 고려하였으며 여러 가지 가정과 추정을 통하여 흡착탑, 펌프, 열교환기, 파이프 등의 장치 및 부속의 배치와 크기, 용량 등을 예상 및 계산하여 실험실 수준으로 설계해 보았다.
또한, 각 장치 및 부속의 구입비용 및 설치비용 등을 고려하여 본 공정이 어느 정도 경제성이 있고, 상용화가 가능한지 판단해 보았다.
본 설계 프로젝트를 위해 조원들과 5차에 걸친 회의를 통해 설계과정이 한 단계씩 진보해나가 최종 발표 전까지 놀라운 성과와 진전을 보였으며 최종결론에 도달할 수 있었다. 또한, 조원 하나하나의 능력과 생각이 조합되어 보다 진취적이고 창의적인 설계를 할 수 있었다.
II. 본론
1. 이론
1.1. 공정원리
흡착 탈수공정은 메탄올과 물의 혼합물을 탈수하기 위하여 다공성의 molecular sieve의 물에 대한 강력한 흡착능을 활용하는 것으로서, 탈수하고자 하는 메탄올 흐름을 molecular sieve 3A가 충진되어 있는 bed에 통과시켜 크기가 작은 물분자를 micropore 내에서 흡착시키고 상대적으로 크기가 큰 메탄올 분자는 지나가게 함으로써 분리시키는 방법이다. 연속적인 운전을 위하여 이러한 흡착 bed를 여러 개 설치하여 메탄올 중 일부는 bed중에 흡착된 물을 탈착시켜 재생시키는데 사용한 다음 다시 흡착 과정으로 순환시키게 된다. 본 공정에서 사용되는 흡착제는 molecular sieve 로서 그 결정구조의 기본적인 형태는 실리콘 또는 Al+과 O-로 구성된 사각구조이다.
