Key words: demulsifier, surfactant, water-oil emulsions, qualitative status of emulsion, interface tension, intermediate layer, specific consumption.
The authors consider the experience in abandoning the lengthy shut-downs in oil treatment processes while processing the heavy asphalt/wax content oil at Yakushkinskaya Oil Treatment Plant.
They have discovered the objects with non-effective demulsifier usage as well as the objects where these demulsifiers have been used in excess (using the methods of microscopy, of measuring interface and surface tensions in water-oil systems, of thermal and chemical studies, etc.).
Recommendations on the most effective demulsifiers are made. Finally due to the use of CTX-5 effective demulsifier and the overall reduction in its demulsifier application they have stabilized the process oil treatment at this process facility.
