Oilfield metal naphthenate formation and mitigation

06/11/2019· Metal ion effects on interfacial properties. The addition of metal ion stabilizes the interfacial naphthenate film, making it less soluble in the bulk phase which translates to an increase in surface pressure (Lutnaes et al. 2006) (Figs. 6, 7).The molecular area also decreases as Ca 2+ and naphthenate anions are electrostatically attracted (Havre et al. 2002).

Calcium Metal - an overview | ScienceDirect Topics

The production process of calcium metal by the metallothermic reduction process (see Equation 2.9.43) is shown in Figure 2.9.43. The raw material CaCO 3 is calcined to produce CaO. Low magnesia content (MgO) is preferred for the reduction feed materials because magnesia is preferentially reduced in this process, thus lowering the reaction efficiency for calcium metal.
