DE-EMULSIFIER FOR BREAKING PETROLEUM EMULSIONS

摘要

Water, contained in petroleum in emulsified form, is separated by adding to the petroleum a conventional deemulsifier and silica in fine particle form. The silica is advantageously in physical mixture with the de-emulsifier. The amount of silica, calculated on the amount of de-emulsifier, is about between 0.1 to 10% per weight. The silica may contain up to 20 percent by weight of at least one of Ti02, Zr02 and A1203.
