(54-93.3 degrees C.) for about 30 minutes to 3 hours with stirring until there is not more than 5% water in the solution and the slop oil and tank remnants or sludges disperse into the diluent.   
     
     
         10 . The method of  claim 9 , wherein the diluent comprises at least one from the group consisting of crude oil, refined petroleum hydrocarbons derived from crude oil, and biofuels including biodiesel

(54-65.6 degrees C.) until at least 99% of the mixture is water-free.   
     
     
         13 . The method of  claim 11 , wherein a desalter then takes out water remaining in the mixture.

         24 . A method of treating slop oil and tank remnants or sludges to knock out water and to disperse the hydrocarbons into a diluent, and to drop solids out of these products, comprising:
 heating the slop oil and tank remnants or sludges to about 130-200 degrees F. (54-93.3 degrees C.) in a vessel;   adding a diluent comprising at least one from the group consisting of crude oil, petroleum hydrocarbons derived from crude oil, and biofuels to the vessel in an amount of at least 50 parts diluent to 100 parts slop oil and tank remnants or sludges;   adding the composition of any one of  claims 14 - 23  to the vessel in a concentration of about 500-3,000 ppm;   maintaining the heat at about 130-200 degrees F.
