Hence, it is unclear whether gas density contributes to the preferential adsorption of supercritical CO2 on coal over CH4 under the same reservoir conditions.carbon dioxide density. Unfortunately, it has been found that these correlations may not be very accurate in terms of predicting the carbon dioxide density under supercritical conditions, especially under the conditions to be anticipated for carbon capture and sequestration (CCS) applications. Similar story exists for carbon dioxide viscosity. The Supercritical carbon dioxide (SC-CO2) has been shown to serve as an environmentally benign substitute for a number of solvents that are typically used for free-radical reactions. 57 Such conventional reaction solvents, as benzene or the chlorinated compound, carbon tetrachloride, can be replaced successfully by SC-CO 2.The supercritical CO2 cooled in brazed plate heat exchangers is studied. ...
