REDUCTION OF FUEL REQUIREMENTS IN CARBON DIOXIDE PRODUCTION FOR BEVERAGE FILLING OPERATION

摘要

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.
