New Chemistries - PC Nap Inhib 12

PC Nap Inhib 12

PC Nap Inhib 12 inhibits the formation of naphthenate deposits and naphthenic acids. In doing so the TAN value of the crude is reduced considerably resulting in a more valuable crude. High TAN crudes are sometimes penalised as some refineries do not want these types of crudes as there is usually considerably more fouling within the refinery process. It is recommended to be injected as far upstream as possible.  Sometimes this is not possible and we have therefore added dispersants to prevent already precipitated deposits from conglomerating. This is a unique formulation, which in some case drop the TAN value by 60%.
