Gas and petroleum recovery operations often produce oil-in-water (O/W) emulsions with varying stabilities. Analyzing the composition of these emulsions is crucial for subsequent crude oil processing, requiring effective flocculation and demulsification processes. The efficiency of emulsion breakdown is influenced by numerous factors. This study evaluated several commercially available flocculants by analyzing interfacial tension, zeta potential, and conducting phase separation tests. Our objective was to identify the most effective flocculant for the model emulsion system and determine the optimal dosing concentration.
