In turn, by knowing the FFH and/or FFE of the building on the parcel, it is possible to use that information while performing a flood risk assessment to a property without requiring a personal inspection of the parcel by a human.

Abstract: A fossil fuel fired power plant exhaust gas clean-up and recovery system is provided to remove detrimental exhaust gases from the power plant exhaust and to produce and reclaim various commercial byproducts. A process includes mixing one liquid solution with a solubilizer in a mixing tank containing water to create a chemical reaction therein to produce an ionic solid compound and an alkaline liquid solution. Simultaneously directing the flue gases and the alkaline liquid solution into the wet scrubber to create a chemical reaction therein. The chemical reaction removes various detrimental exhaust gases from the flue gases and captures CO2 gases therefrom, which are chemically transferred into a newly formed sodium bicarbonate solution. The sodium bicarbonate solution exiting the wet scrubber is stored for resale or reuse in the subject process. The process uses various pathways to distribute the sodium bicarbonate for producing other byproducts.
