    • This invention relates to a novel integrated method for economically processing vacuum residue from heavy crude oils. This is accomplished by utilizing a solvent deasphalter (SDA) in the first step of the process with a C3/C4/C5 solvent such that the DAO product can thereafter be processed in a classic fixed-bed hydrotreater or hydrocracker. The SDA feed also includes recycled stripper bottoms containing unconverted residue/asphaltenes from a downstream steam stripper unit. The asphaltenes from the SDA are sent to an ebullated-bed reactor for conversion of the residue and asphaltenes. Residue conversion in the range of 60-80% is achieved and asphaltene conversion is in the range of 50-70%. The overall residue conversion, with the DAO product considered non-residue, is in the range of 80 W %-90 W % and significantly higher than could be achieved without utilizing the present invention.
    • 本发明涉及一种用于从重质原油经济处理减压渣油的新型综合方法。 这是通过在第一步骤中利用溶剂脱沥青(SDA)与C 3 N 3 C 4 C 5 C 5溶剂 使得DAO产品此后可以在经典的固定床加氢处理器或加氢裂化器中加工。 SDA进料还包括来自下游蒸汽汽提塔单元的含有未转化的残余物/沥青质的再循环汽提塔底物。 来自SDA的沥青质被送入沸腾床反应器以转化残渣和沥青质。 实现了60-80%范围内的残渣转化率,沥青质转化率在50-70%的范围内。 考虑到非残留物的DAO产物的总残留物转化率在80W%-90W%的范围内,并且显着高于在不利用本发明的情况下可以实现的。
