  • Patent number: 9878280
    Abstract: The present disclosure is directed to a method for enriching an inlet air stream utilizing a number of enrichment sub-units connected in series, where each enrichment sub-unit conducts both a dissolution and degasification cycle. Each enrichment sub-unit comprises a compressor, an aeration unit, a deaeration unit, and a pump for the recirculation of water between the aeration and deaeration units. The methodology provides a manner in which the relationship between the respective Henry's coefficients of the oxygen and nitrogen in water may be exploited to enrich the O2 volume percent and diminish the N2 volume percent over repeated dissolution and degasification cycles. By utilizing a number of enrichment sub-units connected in series, the water contained in each enrichment sub-unit acts to progressively increase the O2 volume percent. Additional enrichment sub-units may be added and utilized until the O2 volume percent equals or exceeds a target O2 volume percent.

Vaporized solvent is removed from the gas stream at or above atmospheric pressure and, if necessary, the nebulant is cooled to below 70° C. The volume or surfaces are exposed to the nebulant for a time sufficient to sterilize said volume or surfaces. Also, apparatus for carrying out the method.
