GIMON-BASTIDAS, Raquel Josefina; PEREZ-RODRIGUEZ, Renee Jesús y GONZALEZ-PARTIDA, Eduardo. Computing development of kinetic equations for the dissolution/precipitation of minerals in aqueous fluids. Bol. Soc. Geol. Mex [online]. 2018, vol.70, n.3, pp.567-590. ISSN 1405-3322. https://doi.org/10.18268/bsgm2018v70n3a1.
We developed equations and algorithms for solving a non-linear system of first order differential equations. The system represents a model for the kinetic dissolution and precipitation of minerals in aqueous electrolyte solutions. Our algorithm is valid for temperatures ranging from 20 to 320°C, pressures from 1 to 1000 bar, and ionic strengths of up to 6 mol/kg. Our numerical tool predicts correctly the types and concentrations of: a) minerals dissolved or precipitated through time; b) ions and cations produced and consumed (aqueous species) during the kinetic dissolution/precipitation of one or more minerals in solution.
