Process to upgrade partially converted vacuum residua

A system for upgrading partially converted residuum hydrocarbons, the system comprising:

• a mass transfer device to strip a partially converted residuum hydrocarbon stream into a first distillate stream and a first residuum stream;
• a solvent deasphalting unit for recovering a deasphalted oil stream and an asphaltenes stream from the first residuum stream;
• a vacuum fractionation unit to fractionate the deasphalted oil stream to recover a deasphalted gas oil stream and a heavy deasphalted residuum stream;
• an ebullated bed hydroconversion reactor system for contacting the heavy deasphalted residuum stream and hydrogen with a first hydroconversion catalyst to produce a first effluent;
• a separation unit to recover a hydrocarbon liquid stream and a hydrocarbon vapor stream;
• a fixed bed hydroconversion reactor system for contacting at least one of the first distillate stream, the deasphalted gas oil stream, and the hydrocarbon liquid stream to produce a second effluent.

A process for upgrading a partially converted vacuum residua, comprising:

• stripping with a mass transfer device the partially converted vacuum residua to generate a first distillate and a first residuum;
• deasphalting with a solvent deasphalting unit the first residuum to generate a deasphalted oil and an asphaltenes fraction;
• fractionating with a vacuum fractionation unit the deasphalted oil to recover a deasphalted gas oil distillate and a heavy deasphalted residuum;
• contacting the first distillate and the deasphalted gas oil distillate and hydrogen in the presence of a first hydroprocessing catalyst in an fixed bed hydroconversion reactor to produce a first hydroprocessing effluent;
• contacting the heavy deasphalted residuum and hydrogen in the presence of a second hydroconversion catalyst in a ebullated bed hydroconversion reactor system to produce a second hydroprocessing effluent;
• and
• separating with a high pressure high temperature separator unit the second hydroprocessing effluent to recover a hydrocracked residua and a hydrocracked distillate.
