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. •Effects of adding oil, alcohols and various salts on efficiency of kinetic inhibitors.•Polymer partitioning in HHI.•Investigation of gas hydtare by spectrometery.•New method for investigation gas hydrate inhibitors.
