摘要
在系统压力 6Pa和温度 2 80、 30 0和 32 0℃的条件下 ,采用实验室高真空短程蒸馏仪对辽河、鲁宁管输和大庆原油的常压渣油进行深拔 ,减压馏分油 (VGO)总拔出率 (质量分数 )可达 6 5 %～ 76 %。深拔VGO是合格或基本合格的FCC原料。深拔渣油可作为焦化加工、建筑沥青或重质燃料油的生产原料 ;也可与VGO掺和作为FCC的原料。
Under the pressure of 6 Pa and the evaporation temperatures of 280, 300 and 320°C, the atmospheric residues of Daqing crude oil, Liaohe crude oil and Luning pipeline crude oil were deeply distillated in a laboratory-scale high vacuum short path distillation apparatus. The total yield of the VGO is in the range of 65%-76%. The VGO is suitable for feedstock of FCC. The deep distillated residue can be used as the feedstock for delayed coking to produce asphalt or heavy fuel oil, or mixed with VGO as the feedstock of FCC.
