Naphthenate inhibitors

One problem experienced in oil production systems that are handling a crude oil with a high acid number, is the formation of naphthenate precipitates. The naphthenates can then act as natural surfactants leading either to stabilized emulsions or solid deposits that can plug lines and valves. The naphthenate deposits can accumulate in flowlines, heat-exchangers, separators, filters, hydrocyclones and other surface equipment.
