Magnetic resonance imaging was used to monitor and quantify methane hydrate formation and exchange in porous media. Conversion of methane hydrate to carbon dioxide hydrate, when exposed to liquid carbon dioxide at 8.27 MPa and approximately 4 degrees C, was experimentally demonstrated with MRI data
## Abstract __The absorption of CO~2~ by aqueous NH~3~ solutions has been investigated at atmospheric pressure and 0βΒ°C. The CO~2~ absorption is fast and occurs with high efficiency (88β99β%). The maximum CO~2~βremoval efficiency increases slightly with the NH~3~ concentration. Addition of zinc(II)
