Experience in optimizing oil treatment process by reagents at Yakushkinskoye oil field of Samaraneftegas JSC

Authors: O.S. Kalinina, D.V. Kadyshev, N.P. Meloshenko, Yu.E. Sherstnikova, (SamaraNIPIneft LLC, RF, Samara), B.A. Shishkanov, V.V. Matveev (Samaraneftegas JSC, RF, Samara)

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.
