I doubt they're suggesting they use the untreated flue gases as the gas in the apparatus. I think they're just pointing out that there are industrial sources of co2, n and that finding a use for the co2 helps with another pollution/waste issue
I don't think that this helps really with the pollution issue, since the CO2 is in effect being used as a catalyst and will be emitted afterwards just as it was before. What the article is saying though, is that a large consumer of cement (a high CO2 producing process) is also likely to be a large consumer of clean water.. so that leaves the process of cleaning the water CO2 neutral except for the small amount of power consumed
