The article explores the mechanism of the effect of reagents used for the demulsification of stable water-oil emulsions, which are widespread in oil production and transportation processes. In this regard, the demulsifying properties of the DR-1502 demulsifier used in SOCAR and the new YK-1 composition prepared on its basis are comparatively studied at different temperatures. The studies are conducted in laboratory conditions, and the reduction in the residual water content and the rate of emulsion separation into phases are taken as the main evaluation criteria for each system. The experiments conducted show that the temperature factor directly affects the stability of the emulsion. Thus, when the temperature increases, the emulsion breakdown intensifies, and the separation of the water phase significantly increases. The highest effectiveness of the DR-1502 demulsifier is achieved at a temperature of 70 °C and a concentration of 1000 ppm, and at this time the residual water content decreases to the minimum. YK-1 shows the same performance at lower temperatures and at half the concentration, as the acetone enhances diffusion and surface activity. The results show that YK-1 synergistically enhances DR-1502, increasing its interfacial activity and enabling demulsification with lower energy use.
