摘要

Additive composition for demulsification of water-in-oil emulsions, and method of use thereof, and method of demulsification. The present invention relates to a demulsification composition for demulsification of water-in-oil emulsion formed due to mixing of wash water in the crude oil, wherein the composition comprises: a. a compound selected from the group comprising glyoxal, neutralized glyoxal, glyoxal derivative and a mixture thereof; and b. one or more demulsifiers. In one embodiment, the present invention relates to a method of demulsification of water-in-oil emulsions by treating it with the present demulsification composition. In another embodiment, the present invention relates to a method of using the present additive composition for demulsification of water-in-oil emulsions.
