Witryna1 lut 2024 · Naphthenates can be in the form of soft emulsions such as sodium naphthenate or a hard precipitate such as calcium naphthenate (Turner and Smith, 2005). Both forms are not favoured in the pipeline. Thus, naphthenate deposition is usually reduced through several methods such as caustic soda wash (Adams et al., … WitrynaNaphthenates are formed through interaction of naphthenic acids in crude oil with metal ions such as calcium and sodium. Insoluble in either the oil or water phase, and with a density between that of oil and water, naphthenates tend to accumulate at the oil/water interface and act as surfactants to help stabilize emulsions. Naphthenates can ...
