A process for fluidizing oily heavy slurries chosen from slurries of catalyst fines in hydrocarbon, coke slurries in hydrocarbon, and asphalt residues in hydrocarbon which comprises: (1) heating, with effective mixing, the oily heavy slurries to at least 140°F., thereby forming a heated heavy slurry
A process for fluidizing oily heavy slurries chosen from slurries of catalyst fines in hydrocarbon, coke slurries in hydrocarbon, and asphalt residues in hydrocarbon which comprises: (1) heating, with effective mixing, the oily heavy slurries to at least 140°F., thereby forming a heated heavy slurry; (2) Adding to said heated heavy slurry with effective mixing, an effective fluidizing amount of a fluidizing agent which comprises the ingredients: ________________________________ - Ingredient Wt. Percent ________________________________ (a) water 15-85 (b) an ethoxylated nonyl phenol/ 40-5 formaldehyde resin having a molecular wt. between about 1000-25,000 (c) Surfactants having an HLB 40-5 between about 2.0-25.0, said surfactants chosen from the group consisting of alkanolamide condensates, alkoxylated fatty alcohol phosphates and mixtures thereof; and (d) liquid organic solvents chosen 75-5 from the group consisting of naphthas, aromatic naphthas, heavy aromatic naphthas, alkylated aromatics, light aromatic petroleum distillates, turpentine, dipentene rich turpentine, and mixtures thereof; thereby forming a heated treated heavy slurry, and then mixing effectively until the heated treated heavy slurry becomes fluidized and pumpable. ________________________________
