Abstract: The article describes the development of composite reagents providing dewatering of sludge emulsions of OAO «Samarneftegaz». The study of surface-active properties of the developed composite modifying additive on the basis of the surfactant Neftemol VVD-M and Nezhegol showed that a sharp decrease in interfacial tension occurs at the ratio of neftenol VVD - M to Nezhegol as 1:1. Based on certain Neftemol compositions an effective composit reagent was developed that provides dehydrating of sludge emulsion and its destruction by 96%. The technology of dewatering of sludge emulsion by phase inversion method using the Neftemol MD composition is presented.
