PIT method

The main aims of this research are: To determine the phase inversion temperatures for the formation of oil-in-brine nanoemulsions at various salt concentrations using conductivity measurements; To prepare the nano-emulsions at PIT points, and study their stability by measuring their droplet size, polydispersity and size distribution using dynamic light scattering technique; To confirm the DLS results using Cryo-SEM technique;...

This study focuses on the stability of nano-emulsions produced by phase inversion temperature method using n-Decane and n-Dodecane as the dispersed phase and pure water/brine as the aqueous phase (continuous phase). A non-ionic surfactant (Brij 30) was used in the preparation of the nano-emulsions. Three different types salt namely \(NaCl\), \(KCl\) and \(MgC{l_2}\) were used at different concentrations.

The specific research objectives of this study are: 1. The development of a high throughput method for evaluation of alloys (5xxx Al as model materials in this work) subject to pitting; 2. Understanding the roles of variation in functional groups' in determining the inhibition efficiency; 3. Elucidating the inhibition mechanisms; and 4. Unveiling the role of intermetallic present in Al matrix and their contribution to the inhibition mechanism, particularly the long-term durability of the inhibitor systems.
