PROGRAMA OFICIAL DE DOCTORADO EN GEOLOGÍA E INGENIERÍA GEOLÓGICA Curso: Geochemical Modelling with PHREEQC Profesor Visitante: Dr. Mário Gonçalves (Faculdade de Ciências da Universidade de Lisboa, Portugal) Fechas: 07-10 de Mayo de 2012 Lugar: Aula de Informática Resumen: This course will focus on both basic and advanced topics while using PHREEQC to perform geochemical models. It will address the basic principles of chemical reactions starting with speciation calculations and moving to chemical kinetics, ideal solid solutions, and reactive transport. The objective is to provide attendees with a fairly good overview of the program capabilities, being able to implement the most common geochemical problems, and have a grasp of the more advanced techniques to pursue them on their own and if they will need them in professional life. Contenidos: 1. Modeling chemical reactions with PHREEQC Speciation and saturation index. Dissolution and precipitation of minerals. The common ion effect. Titration of solutions. Surfaces and adsorption. Examples from environmentally relevant systems: carbonate system; acid drainage. The effect of temperature. Displaying the output information for custom graphic construction using the Excel spreadsheet: introducing the BASIC interpreter. 2. Chemical kinetics Kinetics of mineral dissolution. The dissolution rate laws of the main silicate and carbonate minerals. Editing and changing kinetic rate laws. Programming custom rate laws. 3. Solid solutions Ideal and non-ideal solid solutions. Chemical equilibrium of aqueous solutions with solid solutions. Constructing Lippmann diagrams for ideal solid solutions with PHREEQC. 4. 1D transport phenomena The structure of the advection and transport keywords in PHREEQC. Modelling coupled mass transport models: pure advection and advection-dispersion. Examples applied to aquifer chemistry, salt intrusions, and bench top reaction experiments.
