Fluidization of heavy slurries

Abstract: 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/formaldehyde 40-5 resin having a molecular wt. between about 1000-25,000(c) Surfactants having an HLB bwtween about 40-5 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 from the group 75-5 consisting of napthas, aromatic napthas, heavy aromatic napthas, 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.______________________________________
