UTILIZATION OF AN ANHYDRIDE AS A DEMULSIFIER AND A SOLVENT FOR DEMULSIFIER FORMULATIONS |
摘要 |
The present invention includes the use of anhydride compositions, including alkyl and aryl anhydrides, for use as a denmlsif?er in resolving emulsions of water and oil. In particular, the anhydride composition can be used alone or in a blend with other demulsif?ers. Suitable anhydrides suitable for the present invention include acetic and propionic, with acetic anhydride being preferred. The anhydride composition can be added directly to crude oil or other compositions to be resolved. As such, the demulsifier composition includes an anhydride, such as acetic anhydride, alone or in combination with other demulsifiers. The anhydride can be used in an amount ranging between trace and 100% by weight of the demulsifier composition. |
