Abstract
Processes for separating CO2 from a gas mixture containing one or more of hydrogen, nitrogen, argon, CO, and methane or a combination thereof is described. The processes involve, for example, cooling and partial condensation of the gas mixture, preferably by a single loop refrigeration system with a mixed refrigerant, phase separation of the partially condensed stream, and distillation of the CO2-rich liquid stream. At least a portion of the liquid CO2 produced from the processes during the off-peak electricity demand hours can be stored and then heated, vaporized, further heated, and expanded for power generation during the peak electricity demand hours, helping balance the supply and demand of electricity of the electricity grid.
