Abstract :
Analysis of a dynamic light scattering instrument "Wyatt DynoproNanoStar" was used to detect the accumulation of surfactant in the oil phase. Triple measurements were performed for each sample and at least two samples were tested for each level of surfactant concentration to ensure reproducibility. The detection temperature was controlled at the same temperature by segmentation experiments. The accumulation properties of BAC surfactant in toluene were investigated using DLS and samples were presented in Figure 3, including the total radius and intensity of the collected light signal, C12, C14, and toluene C16, from the oil phase in the water-oil partitioning equilibrium from the surface. Net BAC was sampled. As can be seen, both the particle radius and the intensity of the C12 and C14 signals varied sharply within the evaluated concentration range, indicating that C12 and C14 do not form micelles in toluene. In this research, a multi-physical model, integrated corrosion inhibition model (ICI), is presented theoretically and empirically to evaluate integrated water-oil separation, aggregation, adsorption / desorption, and corrosion inhibition of mixed surfactant inhibitors in water-containing oils. We pay salt in Gachsaran Oil Company. Steel Pipe Environments (WOS). The ICI model is based on three main sub-models that consider water-oil surfactant classification, micellation, effective adsorption / desorption on the substrate, surfactant type, surfactant-solvent interactions, surfactant-contrion pair, and side surfactant interactions, etc. opnions have been asked. Acts as a basic framework in the design, selection, optimization, and use of various pure and mixed surfactant inhibitors in WOS environments. In summary, a comprehensive model, the ICI model, has been theoretically developed and empirically validated to evaluate the partitioning, aggregation, and corrosion inhibition of surfactant (both homologous and inhomogeneous) inhibitors (water-containing) and oil-steel pipe.
