<p>The method of supplying purified CO2 to beverage filling process, which includes compressing ambient air, feeding the compressed air and hydrocarbon fuel to a burner, for combustion to form CO2 and water, supplying flue gas containing CO2; N2, O2 and water to an extraction process wherein CO2 is extracted as a high purity gaseous stream, compressing, drying and liquefying the CO2 in the stream, for storage, and, in response to beverage filling needs for CO2, vaporizing liquid CO2 and delivering gaseous CO2 to a beverage filling operation, and, in this process or similar processes, re-using CO2 obtained from the beverage filling operation. Typically, such obtained CO2 is returned to the burner, via a blower, or may alternatively be supplied to burner output flue gas.</p> |
