ABSTRACT:
Water, contained in petroleum in emulsified form, is separated by adding to the petroleum a conventional de-emulsifier 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 TiO.sub.2, ZrO.sub.2 and Al.sub.2 O.sub.3.
