Summary: | Methods for resolving emulsions in a hydrocarbon stream by contacting the hydrocarbon stream with a demulsifying composition are disclosed. More specifically, there is disclosed a method of resolving an emulsion present in a hydrocarbon stream comprising: contacting said hydrocarbon stream with a demulsifying composition, said demulsifying composition being a colloidal micellar solution and comprising at least one C4-C12 alkyl phenol-formaldehyde resin alkoxylate, an oil phase, and an aqueous phase, wherein said oil and aqueous phases form the colloidal micellar solution. Demulsifying compositions for treating a hydrocarbon stream are also disclosed, wherein the demulsifying composition comprises at least one C4-C12 alkyl phenol-formaldehyde resin alkoxylate. More specifically, there is disclosed a demulsifying composition for treating a hydrocarbon stream comprising at least one C4-C12 alkyl phenol-formaldehyde resin alkoxylate, an oil phase, and an aqueous phase, wherein said oil and aqueous phases form a colloidal micellar solution, and wherein said demulsifying composition comprises 0.1 wt% to about 90 wt% water based on a total weight of said demulsifying composition. |
