  • Dissolution Kinetics of Dolomite in Water at Elevated

    2007-11-1 · Kinetic experiments of dolomite dissolution in water over a temperature range from 25 to 250°C were performed using a flow through packed bed reactor. Authors chose three different size fractions of dolomite samples: 18–35 mesh, 35–60 mesh, and 60–80 mesh. The dissolution rates of the three particle size samples of dolomite were measured. The dissolution rate Solubility and Dissolution Kinetics of Dolomite in Ca–Mg,2000-11-1 · A previously proposed kinetic model of successive reactions for dolomite dissolution near equilibrium—a fairly rapid dissolution of the CaCO 3 component in equilibrium and a rate-limiting protonation reaction dependent on the activity of the MgCO 3 component—appears to fit the experimental data.

  • An experimental study of dolomite dissolution kinetics at

    The kinetics of dolomite dissolution have been experimentally investigated under subsurface conditions characteristic of the Rotliegend gas fields in the NE of The Netherlands. Experiments were performed in closed, stirred, batch reactors at far from equilibrium conditions, with dolomite powders of different grain sizes. The experiments were repeated for all grain sizes at 25°C Kinetics and Mechanism of Dolomite Dissolution in Neutral,Steady-state dissolution rates of dolomite were measured at 25°C in a mixed-flow reactor as a function of pH (from 5–12), ionic strength (0.002 < I < 0.1 M), total dissolved carbonate (10−5 < ∑CO2 < 0.1 M), calcium (10−6 −0.003 M), magnesium (3 · 10−7 −0.005 M), and inorganic (sulfate) and organic (acetate, ascorbate, formiate, tartrate, oxalate, citrate, and EDTA) ligands
