윤활유의 용매정제 방법Solvent Refining Method of Lubricant

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

첨부도면은 용매 정제공정을 나타내는 유통도임.The accompanying drawings are flow charts showing the solvent purification process.

Claims (1)

소량의 용매를 함유하는 라피네이트 상과 다량의 용매를 함유하고 추출지역으로 부터 각기 회수된 추출상을 형성하는 추출지역내에서 윤활유원료중 방향족 성분에 대한 선정적인 용매로 윤활유원료를 접촉시키고, 추출용매 분리지역내의 상기 추출상으로부터의 일부 용매를 제거한 후 용매증기와 스트리핑 가스와의 혼합물을 형성하는 불활성 스트리핑 가스로 추출상으로부터의 상기 용매의 또 다른 부분을 스트리핑하여 윤활유원료를 용매 정제하는 방법에 있어서 ; 용매 증기가 상기 윤활유에 의해서 상기 스트리핑 가스로부터 흡수되고 상기 윤활유에 함유된 이물질인 물이 적어도 일부 증발되어 상기 윤활유로부터 분리된 수증기와 불활성 가스와의 혼합물을 형성하는 상기 용매 추출 조작전에 첫번째 접촉지역에서 상기 윤활유원료를 불활성 스트리핑 가스와 용매증기와의 혼합물로 치밀하게 접촉시키는 것을 특징으로 하는 윤활유의 용매정제방법.Contacting the lubricating oil raw material with a selective solvent for the aromatic components of the lubricating oil in the raffinate phase containing a small amount of solvent and the extraction region containing a large amount of solvent and forming the extracted phase respectively recovered from the extraction region. Removing some of the solvent from the extraction phase in the solvent separation zone and stripping another portion of the solvent from the extraction phase with an inert stripping gas which forms a mixture of solvent vapor and stripping gas. In; At the first contacting zone prior to the solvent extraction operation, solvent vapor is absorbed from the stripping gas by the lubricant and foreign water contained in the lubricant is at least partially evaporated to form a mixture of water vapor separated from the lubricant and an inert gas. And lubricating oil raw material is intimately contacted with a mixture of an inert stripping gas and a solvent vapor. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
