One has to imagine that the existing liquid amine broth @ 30%
Amine concentrations currently being examined in a "bubbler(upright vessel- flue gas enters the bottom of the vessel)", manner", are for the benifits volume of contact area of amine to gas stream.

But it seems energy intensive, working a gas stream, through a liquid medium and also the volume of area of the liquid measured against the volume of the flue gas would require a number of, or large reactor vessels, imo.( One cannot force a gas thru a liquid, the gas only travels at a set speed).

So a hingepoint of our processs, it seeems to me, is the nonoporous silica and dry medium. This allows a higher surface area for exposure for the amines to the Co2. Plus a faster pass thru rate than liquid bubblers.

I've been digging into DOE studies on the amine-co2 results from simple coating of silica and other products with amine products and am reassured the low temp, low pressure capabilities will work with a amine based product attached to a silica surface.

Now I'm curious towards the nanoporous surface. The finest/smallest construct I can find is a hexagonal tube shape in the 60-100a size range. That certainly falls under "nano", lol.
