Abstract

본 발명은 원유 조질 분획물을 열처리함으로써 석유산, 예를 들면 나프텐산을 상기 원유 또는 조질 분획물로부터 제거하는 방법에 관한 것이다.The present invention relates to a process for removing a petroleum acid, for example naphthenic acid, from the crude oil or crude fraction by heat treating the crude crude fraction.

Description

나프텐산의 열분해 방법Pyrolysis method of naphthenic acid

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제1도는 실시예 4에서 첨가된 물의 양에 대한 총 산가(TAN)의 감소율을 보여준다.Figure 1 shows the rate of reduction of the total acid value (TAN) over the amount of water added in Example 4.
