Deasphalting of gas oil from slurry hydrocracking
Abstract:
Integrated slurry hydrocracking (SHC) and solvent deasphalting (SDA) methods for making slurry hydrocracking (SHC) distillates are disclosed. Representative methods involve passing a slurry comprising a vacuum column resid, a recycled, deasphalted oil obtained from SDA, and a solid particulate through an SHC reaction zone in the presence of hydrogen to obtain the SHC distillate. Fractionation or distillation in the SHC product recovery section yields a combined SHC gas oil/SHC pitch stream that is sent to SDA. In a representative embodiment, vacuum distillation in the SHC product recovery is avoided, thereby eliminating equipment that is often most susceptible to fouling.
