An intriguing idea, but without any idea of the relative costs, it is difficult to judge its feasibility.

 Please consider a different policy strategy or explore an investment strategy which would build monetize benefits.

The water vapor included in flue gas is not lost.  It enters the natural water cycle and returns in the form of precipitation.  Removing it will mean less precipitation - somewhere.

Since the details of operation of the Sidel SRU Condensing Economizer are not explained one is left to assume it requires energy to run and that there is no associated way the removed heat is put to productive use.  The result is a net increase in energy consumption not a reduction.

This is a solution that claims to address the problem of climate change but is based on the continued use of a fossil fuel.  While natural gas yields 44% less CO2 compared to the equivalent BTUs from coal, it is still a fossil fuel and it's use is becoming one of the largest contributors to climate change.  The cause is not just from the CO2 emitted, but also from the released methane associated with every step of its supply chain.  Studies have suggested that because of these fugitive methane emissions, the switch to natural gas is not benefiting the climate.  In addition, since much of the domestically produced natural gas is associated with hydraulic fracturing of wells, anything that contributed to its continued use can not be seen as relief to the energy/water nexus.  Fracking water is lost to the natural water cycle because it becomes contaminated with fracking fluids and any that is recovered is permanently injected into disposal wells, threatening the quality of our natural aquifers.

While the device described may be commercially useful to some industries, it does not represent the sort of innovation that Climate CoLab is trying to foster.
