APPARATUS AND PROCESS FOR DISSOLUTION OF GASES IN LIQUID

摘要

The device (100) for dissolving the gas in the liquid includes gas injection means (14) for introducing gas into the liquid and a contact chamber (20) for containing a downflowing stream of the liquid to be treated. The pressure within the downflowing stream increases as it descends and at the elevated pressure the capacity of the liquid to take gas into solution is greatly increased. This apparatus (100) for dissolving gas may conveniently be located below ground level. A conduit return means (22) is provided for routing undissolved gas from a region (29) at high pressure to an upstream portion (16) of the liquid stream so that the gas can be reintroduced for dissolution.
