Three basic methods to separate gases - CO2 Capture

Cryogenic separation is widely used commercially for streams that already have high CO2 concentrations (typically >90%) but it is not used for more dilute CO2 streams. A major disadvantage of cryogenic separation of CO2 is the amount of energy required to provide the refrigeration necessary for the process, particularly for dilute gas streams.The Effect of Temperature, Pressure and Co-Solvent on a widely used low temperature solvent separationThe importance of temperature, pressure and co-solvent fraction on the separation of racemic 1-phenyl-1-propanol on a cellulose-based chiral stationary phase was investigated using a chemometric approach where the true instead of the set operational variables were used as input data.The Effect of Temperature, Pressure and Co-Solvent on a widely used low temperature solvent separationThe importance of temperature, pressure and co-solvent fraction on the separation of racemic 1-phenyl-1-propanol on a cellulose-based chiral stationary phase was investigated using a chemometric approach where the true instead of the set operational variables were used as input data.
