Abstract
This disclosure sets out a metal salt removal procedure for use with a crude oil flow. A small amount of water is injected to form water bubbles surrounded by oil. An ethylene oxide reacted with polypropylene glycol at 350.degree. F. or so yields a water soluble demulsifier added at the rate of a few ppm to the water in oil mix. The added reaction product, a polyol enables metal salt isolation in the water.
