separating, in a resin flash drum, the resin feedstock into a solvent fraction and a flashed resin fraction;

feeding the flashed resin fraction to a hydrotreating reactor to create a resin output;

feeding the resin output from the hydrotreating reactor to a first heat exchanger to exchange heat between the resin output and the flashed resin fraction and feeding the resin output from the first heat exchanger to a second heat exchanger to exchange heat between the resin output and the fraction comprising DAO and resin;

feeding the resin output from the second heat exchanger to a separator;

separating, with the separator, hydrogen from resin output from the second heat exchanger;

feeding the resin output from the separator to a stripper;

separating, with the stripper, the resin output from the separator into a light ends fraction and a bottoms fraction; and

separating the resin from the solvent solution, producing a resin product and a mixture comprising the oil and the solvent;

applying heat to the mixture so as to vaporize a fraction of the solvent;

removing the vaporized solvent fraction from the mixture leaving a resin-free deasphalted oil (DAO) product;

integrating the resin product with a hydroprocessing process, wherein integrating the resin product with the hydroprocessing process comprises:

separating, in a resin flash drum, the resin product into a solvent fraction and a flashed resin fraction;

feeding the flashed resin fraction to a hydrotreating reactor to create a resin output;

feeding the resin output from the hydrotreating reactor to a first heat exchanger to exchange heat between the resin output and the flashed resin fraction and feeding the resin output from the first heat exchanger to a second heat exchanger to exchange heat between the resin output and the fraction comprising DAO and resin;

feeding the resin output from the second heat exchanger to a separator;

separating, with the separator, hydrogen from resin output from the second heat exchanger;
