摘要: An improvement in the method of transporting viscous hydrocarbons through pipes is disclosed. Briefly, comprises adding water containing an effective amount a combination (a) sodium or ammonium salt ethoxylated alcohol sulfate and (b) surfactant selected from group consisting certain polyoxyethylene-polyoxypropylene block polymers oxyethylated alcohols. The resulting oil-in-water emulsion has lower viscosity more easily transported.
