ABSTRACT:
A method for eliminating foam in hydrocarbon distillation systems where the foaming is caused by an ionic surface-active substance is involved. Foam is eliminated by the addition of an effective amount of a surfactant electrolytically opposite to the surface-active material already in the system. The surfactant added and the surface-active substance already in the system complex to form a non-foaming combination, allowing distillation to proceed without foaming.
