Abstract
Partitioning behaviours of commercial inhibitors like ethoxylated amine and phosphate ester were studied by carrying out partitioning tests and determining the concentration of the inhibitors by conventional colorimetry method and Inductively Coupled Plasma spectroscopy. The tests were performed using various water cuts, hydrocarbon phases, and concentrations in order to find out the effects of these factors. Ethoxylated amine distributed itself mostly into aqueous phase regardless of the conditions. Comparison of partitioning behaviour of phosphate ester in low and high water cut mixtures resulted in some loss of the inhibitor from bulk water phase as water cut decreased. Phosphate ester inhibitor showed significant synergistic effect with other nitrogenous compounds during the partitioning experiments.
