This process uses a low-thermal plasma reactor to convert carbon dioxide, natural gas, and water vapor into acetic acid, waste liquid, and flue gas. The plant requires co-location with a corn ethanol plant for carbon dioxide feed and for the disposal of liquid waste (made primarily of ethanol and methanol) as an ethanol additive. The acetic acid is the target liquid product for this process. The flue gas has significant energy value and may also be sold. In the best case scenario, the plant achieves a 33.78% internal rate of return with a $27,000,000 net present value. Other worse case scenarios are analyzed with the least favorable resulting in a 13.3%-16.8% internal rate of return.
