Chemical additive comprising selected surfactants, dispersants, and degreasers that liquefy, disperse, demulsify, degrease, inhibit corrosion and scale formation, lower pour-point/cloud-point of petroleum, coal, Fischer-Tropsch synthesized, or naturally occurring paraffin-based wax and asphaltene, comprising preferably mixture of oil soluble, surface active polyethoxylated compounds; organic solvents (non-hydrocarbon) used as degreasing agents, pine oil, and butyl cellusolve; a mixture of oil/water-soluble dispersing copolymers of partially sulfonated, maleic anhydride and polystyrene with molecular weight ranging from 2,000 to 2,000,000; and saturated higher fatty acids and alkyl-phenolic based compound acting as corrosion inhibitors; capable of converting crystalline wax (paraffin) in slop oil into amorphous form at room temperature, allowing the wax to be dissolved and maintained in solution in crude oil without heating, reducing wax build-up in pipelines, processing and transportation equipment, recovery of hydrocarbons in slop oil, resulting in final crude oil blends with B.S. & W. (wax or asphaltene separation) of 0.00%.
