Systems and methods for concentrating a substance recovered from a gas stream

Abstract

Systems and methods of producing a concentrated solution from a gas stream are disclosed. The method of producing a concentrate solution includes introducing the gas stream having the contaminant into an absorption chamber, introducing a dilute liquid having the contaminant into the absorption chamber, at least one of the gas stream and the dilute liquid being at an elevated temperature, and contacting the gas stream with the dilute solution to produce a liquid-enriched gas stream and a concentrate solution. The systems for producing a concentrated solution include a source of a gas stream having a contaminant, a source of a dilute solution having the contaminant, and an absorption chamber fluidly connected to the source of the gas stream and the source of the dilute solution. The source of the dilute solution can have a subsystem for removing contaminants from the gas stream, constructed and arranged to receive the gas stream or a liquid-enriched gas and produce the dilute solution.
