Laboratory Measurement of Sorption in Porous Media
Abstract/Contents
- Abstract
- Adsorption is increasingly being acknowledged as a storage mechanism in vapor dominated geothermal systems. In this study, two methods were employed to measure adsorption and desorption is porous media. The first was with a commercial prototype BET apparatus. A study into the rock particle sizes used in experiments and the rate of pressure change used to determine equilibrium were made. The sorption isotherms measured for geothermal rock demonstrated a strong hysteresis between the adsorption and desorption curves. The second method studied used a transient pressure model. Samples were filled with steam and the steam allowed to adsorb. One end of the core was then opened and the pressure decline with time was measured. This data was matched using a finite difference program utilizing the Langmuir equation and a regression program, producing the constants for the Langmuir equation. Data has been collected but computer program errors have prevented the regression step of the procedure.
