Dissolution Characteristics of Limestone in Laboratory Experiments

Calcium Carbonate Dissolution Rate in Limestone Contactors

The project summarized here investigated some of the parameters and relationships used to predict the performance of limestone contactors. The purpose of the project was to study the effect of limestone composition, especially the dolomite [CaMg(CO 3) 2 ] and impurity content of the stone, on the kinetics of carbonate mineral dissolution and to determine the effect of temperature on the rate of...

Pore-scale controls on calcite dissolution rates from flow-through laboratory and numerical experiments.

A combination of experimental, imaging, and modeling techniques were applied to investigate the pore-scale transport and surface reaction controls on calcite dissolution under elevated pCO2 conditions. The laboratory experiment consisted of the injection of a solution at 4 bar pCO2 into a capillary tube packed with crushed calcite. A high resolution pore-scale numerical model was used to simula...

Spontaneous switching of permeability changes in a limestone fracture with net dissolution

[1] Results are reported for water flow-through experiments conducted on an artificial fracture in limestone at room temperature and under ambient confining stress of 3.5 MPa. Tests are concurrently monitored for mineral mass loss or gain and for changes in differential pressure between the inlet and outlet, throughout the 1500-hour duration of the experiment. Periodic imaging by X-ray computed...

Laboratory Experiments in Political Economy

The financial support of the National Science Foundation and the Center for Economic Policy Studies at Princeton University are gratefully acknowledged. I wish to thank many coauthors for sharing their insights about political economy experiments. I am especially indebted to Richard McKelvey. The editors provided helpful comments on an earlier draft.
