Open the CIPO recordAbstract From the Canadian patent
This invention relates to an ejector for the CO2 process in neutralizing alkaline waters. Modifications to the conventional Venturi tube based upon studies of reactions between the liquid and gas phase, properties of solutions and their alkaline components, have allowed the development of such an ejector. This invention deals with the different components of the ejector and their influences on the neutralizing reaction showing that efficiency levels of about 90% could be obtained as a consequence of the geometry proposed for this type of equipment.
