摘要
研究了几种用于生产润滑油基础油的石蜡基减压渣油的性质,及其在溶剂脱沥青试验中的操作条件,并与中间基减压渣油的溶剂脱沥青实验结果相比较,分析了减压渣油在溶剂脱沥青过程中出现异常现象的原因。总结了石蜡基减压渣油的进料性质。
Properties of several paraffin base vacuum residues and their solvent deasphalting processes were investigated,and the results were compared with experiment results of solvent deasphalting process of intermediate base vacuum residues.Reasons of abnormal phenomena that appeared in solvent deasphalting process were analyzed.Properties of paraffin base vacuum residue as raw materials of solvent deasphalting were summarized.
