润滑油的制取
点击数:39 11:18:58 来源:
& & 是由石油经炼制而得到的一种石油产品。
& & 石油的主要成份是碳氢化合物,简称烃。烃类按其结构的不同,分为烷烃、环烷烃、芳香烃和不饱和烃等类。不同烃类由于沸点不同,所以石油可以用物理方法分成不同馏出沮度的组份,构成汽油、煤油、柴油、润滑油等石油产品。一般35℃一200℃的馏份为汽油,占原油重量的9%一10%; 175℃一300℃的馏份为煤油,占原油重量的10%一11 % ; 200℃一350℃的馏份为柴油,占原油重量的7%左右;350℃以上的馏份为润滑油原料或裂化原料,称为常压渣油。所有的润滑油,按照馏份的切取可分为:馏份润滑抽、残渣润滑油、调和润滑油。
& & 1.馏份润滑油
& & 将常压渣油利用降低压力从而降低油料沸点的原理,进行减压、蒸馏,并经过溶剂或酸碱除去油中的非理想成份、精制、溶剂脱蜡除去油中的高分子烷烃,以降低润滑油的凝点、白土补充精制除去油中的机械杂质等手段可获得的各种润滑油,称为馏份润滑油。馏份润滑油馏份轻,粘度小,油性差。常压渣油经减压蒸馏的残留物.称为减压渣油.如损耗系统用油、专用锭子油等。
& &2.残渣润滑油
& & 将减压渣油经燕馏、精制后可获得残渣润滑油。这种油含沥青质、胶质较多,枯度大。如汽缸油、轧钢机油等。
& &3.调和润滑油
& &润滑油滤油机 将馏份润滑油和残渣润滑油按不同比例合成、分馏、精制,可获得各种粘度和凝固点的调和润滑油。这种油凝点很低,粘温性能良好。例如:压缩机油、仪表油、冷冻机油等。
