Investigation the partitioning amount while the simultaneous use of thermodynamic and kinetic hydrate inhibitors by UV-spectrometery analysis

In this paper the amount of partitioning while the simultaneous use of THIS and a KHI inhibitors is examined and, results were investigated. The effects of adding oil, alcohols and salts on the efficiency of kinetic inhibitors were investigated using UV spectrometry and Beer-Lamberdt law. Samples of the mentioned inhibitors were prepared using a kinetic inhibitor (Poly Vinyl Pyrrolidone) and then spectrometry was conducted. Results indicated positive impacts whenever salt was added to the solution; since salt addition caused stronger bonds between kinetic inhibitor and water molecules. It was found that between salts NaNO3 with 70% had the highest and KCl with 39% had the lowest percentage of partitioning. Addition of oil showed fewer negative impacts. Bangestan oil with 2% of partitioning had the least negative effect and n-heptane with 7% had the most negative effect. Normal butanol (16%), acetone(11%) and ethylene glycol with 18% did not have major negative influences.
