Integrated resid deasphalting and gasification

A method for hydroprocessing deasphalted oil, comprising:

• performing solvent deasphalting in a deasphalting unit under effective solvent deasphalting conditions on a feedstock having a T5 boiling point of at least about 400° C. to form a first fraction comprising deasphalted oil and a solvent and a second fraction comprising deasphalter rock and the solvent, the effective solvent deasphalting conditions producing a yield of deasphalted oil of at least about 50 wt % of the feedstock;
• recovering solvent from at least one of the first fraction and the second fraction, the recovering comprising generating heat for the recovering by combustion of a solvent recovery fuel comprising H2;
• gasifying at least a portion of the deasphalter rock to form synthesis gas, the solvent recovery fuel comprising at least a portion of the synthesis gas;
• desulfurizing at least a portion of the synthesis gas to form a desulfurized synthesis gas;
• separating at least a portion of the desulfurized synthesis gas to form an H2-enriched stream;
• hydroprocessing at least a portion of the deasphalted oil in a hydroprocessing unit under first effective hydroprocessing conditions in the presence of an H2-containing gas to form a hydroprocessed effluent comprising a sulfur content of 500 wppm or less, the H2-containing gas comprising at least a portion of the H2-enriched stream;
• forming a fuel source by combining at least a portion of the synthesis gas and a hydrogen-containing purge stream;
• introducing a first portion of the fuel source to a deasphalting unit furnace;
• heating the deasphalting unit by using the first portion of the fuel source in the deasphalting unit furnace;
• introducing a second portion of the fuel source to a hydroprocessing heating unit;
• heating the hydroprocessing unit by using the second portion of the fuel source in the hydroprocessing heating unit;
• purifying at least a portion of the desulfurized synthesis gas to form a hydrogen stream;
• compressing the hydrogen stream to form a compressed hydrogen stream;
• and
• introducing the compressed hydrogen stream to the hydroprocessing unit;
• separating the hydroprocessed effluent to form at least a fuels boiling range fraction and a bottoms fraction;
• hydroprocessing at least a portion of the hydroprocessed bottoms fraction under second effective hydroprocessing conditions, the second effective hydroprocessing conditions comprising hydrocracking conditions and catalytic dewaxing conditions, to form a catalytically dewaxed effluent comprising a 950° F.+ (510° C.+) portion having a VI of at least 80 and a pour point of −6° C. or less;
• and at least one of:
• a) solvent extracting at least a portion of the catalytically dewaxed effluent to form a solvent processed effluent, and b) solvent dewaxing at least a portion of the catalytically dewaxed effluent to form a solvent processed effluent, wherein the catalytically dewaxed effluent is underdewaxed;
• wherein the solvent processed effluent has a cloud point of −2° C. or less.
