【摘要】：采用短程分子蒸餾技術(shù),對獨山子石化公司蒸餾裝置減壓渣油進行了深拔分離,考察了不同拔出深度窄餾分的性質(zhì),并對按比例調(diào)和的寬餾分減壓深拔重蠟油作為催化裂化裝置原料的性質(zhì)進行了分析評價,結(jié)果表明,蠟油Ⅱ終餾點達到600.80℃時,蠟油Ⅱ收率提高2.32%,殘?zhí)恐颠_1.38%,已不能滿足催化原料殘?zhí)恐悼刂埔蟆０纬鼋K餾點大于600℃后,殘?zhí)�、金屬含量等指標迅速上�?重蠟油已不能滿足催化原料控制指標。在工業(yè)應(yīng)用中,建議通過優(yōu)化和調(diào)整蒸餾裝置的操作,控制拔出深度和重蠟油殘?zhí)?達到增加催化裂化原料來源、改善全廠蠟油平衡的目的。
[Abstract]:The vacuum residue of the distillation unit of Dushanzi Petrochemical Company was separated by the short-range molecular distillation technology. The properties of vacuum and deep drawn heavy wax oil as feedstock in FCC unit were analyzed and evaluated. The results showed that when the final distillation point of wax oil 鈪，
