Patent ID: 7416661

Claim:
An apparatus for simultaneously removing a first gas and at least one alkaline species from water, comprising: a) a vessel for receiving a flow of water, where the water comprises a first gas and the alkaline species; b) a plurality of partitions sequentially dividing the vessel into at least a first gasification chamber and a second gasification chamber, each adjacent chamber fluidly communicating with one another, each chamber having a vapor space, in the absence of communication between the vapor spaces of adjacent chambers; c) an inlet to introduce the flow of water into the gasification chambers; d) a gas feed to introduce a second gas into at least the first gasification chamber; e) an acid feed tube to introduce an acid into each gasification chamber to react with the alkaline species; f) a mechanism for ingesting and mixing the second gas and the acid into the water of each gasification chamber for creating a turbulent area and for displacing at least a portion of the first gas to the vapor space of each chamber; and g) a gas outlet in each chamber for removing the displaced first gas from the vapor space of each chamber; and h) an outlet for removing clarified water from the vessel.
