Latest Patents

One of David's latest patents is titled "SOcapture using carbonate absorbent." This invention outlines a desulfurization gas process that includes water vapor, CO, and SO (x=2 and/or 3). In this process, the gas interacts with a cooled alkaline aqueous solution that has a temperature lower than the initial gas temperature. This interaction allows for the cooling of the gas, condensation of some water vapor, and absorption of SO in the carbonate-containing solution. The result is an SO-depleted gas and an acidic aqueous solution containing sulfate and/or sulfite ions. The SO-depleted gas and a portion of the acidic aqueous solution can then be withdrawn from the treatment unit. Additionally, carbonate of the alkali metal can be added to the remaining acidic aqueous solution to create a made-up alkaline aqueous solution, which can be cooled and reused.
