Abstract
A metal salt removal procedure for use with a crude oil flow is disclosed. A small amount of water, and a caustic in the range of 7-12 pH, and preferably 9-12 pH, are injected to form water bubbles surrounded by oil. An ethylene oxide reacted with polypropylene glycol at 350° 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.
