Description

탄화수소 혼합물로부터의 노르말 파라핀의 등압분리공정
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
병렬로 조작되는 세개의 흡착층을 갖는 본 발명에 따른 장치의 흐름도.

Claims (1)

  1. 탄소수가 10-25인 노르말 파라핀과 비노르말 탄화수소 함유되어 있는 원료내의 비노르말 탄화수소로부터,
    (1) 상기 원료를 분자체(sieve)흡착층을 통과시킴으로써 노르말 파라핀의 선택적인 흡착,
    (2) 탑의 유출단부로부터 그농도의 비노르말 탄화수소를 함유하는 증기를 유출시키기 위한 n-헥산과의 병행류 퍼어지.
    (3) 상기 탑으로부터 노르말 파라핀 흡착체를 탈착시키기 위한 n-헥산과의 역행류 퍼어지.
    (4) 상기 분리된 노르말 파라핀과 비노르말 탄화수소로부터의 n-헥산의 회수.
    그리고,
    (5) 상기 탑층의 퍼어징을 위한 상기 n-헥산의 순환에 의해 노르말 파라핀을 분리하기 위한 등압공정에 있어서, 그 개선점이 상기의 역행류 퍼어지 단계로부터 병행류 퍼어지에 사용되는 상기 n-핵산의 공급원으로 이용키 위해 탈착 유출물의 일부를 전환시킴으로써 상기순환 n-핵산의 처리에 소모되는 에너지와 장치의 크기가 감소되도록 한것을 특징으로 하는 탄화수소 혼합물로 부터의 노르말파라핀의 등압분리 공정.
