NOVELTY - A composition comprises ingredients listed in Rows 1-12 of Column 1 and/or Column 2 of Table 1 in the specification e.g. Biosoft-101 DDBSA (co-additive for demulsifier (dodecyl benzene sulfonic acid) (toluene sulfonic acid or any other alkyl benzene sulfonic acid such as toluene sulfonic acid, xylene sulfonic acid)), or C-4100 (very powerful demusifier (diisopropyl naphthalene sulfonic acid (35-70%), sodium dodecyl benzene sulfonate (10-30%), 1,2,4-trimethylbenzene (5-15%), sulfonic acid (0.5-5%), xylene (0-3%), cumene (0-3%)) (other alkyl, di-alkyl, trialkyl naphthalene sulfonic acids)).    USE - As composition for 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; for treating drill cuttings to reduce water content; and for reducing water content and solids content in a biofuels mixture made from the pyrolysis of wood (claimed).

INDEPENDENT CLAIMS are included for the following:    (1) 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, involving: 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 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 to the vessel in a concentration of about 500-3000 ppm; maintaining the heat at about 130-200 degrees F (54-93.3 degrees C) for about 30 minutes to 3 hours with stirring until there is not greater than 5% water in the solution and the slop oil and tank remnants or sludges disperse into the diluent;    (2) a method of treating drill cuttings to reduce water content, involving: heating the drill cuttings to about 90-120 degrees C in a vessel; adding the composition to the vessel in a concentration of about 1000-10000 ppm; maintaining the heat at about 90-120 degrees C for about 30 minutes to 3 hours with mixing until the drill cuttings are at least 98% oil free and oil recovered from the cuttings is at least 99% water free; and    (3) a method (M1) of reducing water content and solids content in a biofuels mixture made from the pyrolysis of wood, involving heating the biofuels mixture to about 130-150 degrees F (54-65.6 degrees C); adding to the biofuels mixture about 500-3000 ppm of the composition; maintaining the heat at about 130-150 degrees F (54-65.6 degrees C) until at least 99% of the mixture is water-free.
