Low pressure generating plasma reactor closed loop process and system
The present invention provides a low pressure generating plasma reactor closed loop process, comprising: feeding a fresh feed gas flow and a fresh feed absorption liquid flow to a plasma reactor closed loop comprising a condenser, a liquid loop, a recycle gas loop, and a plasma generator; converting feed gas to reactive plasma products in the plasma generator; quenching and absorbing the reactive plasma products into an absorption liquid circulating in the liquid loop where the reactive plasma products react to form liquid reaction products, thereby generating low pressure in the closed loop; monitoring the composition and low pressure of the recycle gas loop and, if the pressure increases, adjusting the composition of the fresh feed gas flow and/or fresh feed absorption liquid flow to bring the composition of the feed gas towards stoichiometric ratio with the absorbed reactive plasma products; extracting circulating absorption liquid, containing the liquid reaction products, from the plasma reactor closed loop as a product flow. The present invention also provides a low pressure generating plasma reactor closed loop system, comprising a plasma generator, a condenser, a recycle gas loop, a liquid loop, and a pump.
The present invention relates to a process suitable for reducing ammonia loss and odor from organic material to the atmosphere. The process comprises feeding air to a plasma generator to produce a concentration of 0.1-12% by volume of NOx in the air by direct nitrogen fixation. Cooled air containing NOx from the plasma generator is fed to an absorption system comprising at least two absorption loops, wherein a first absorption liquid is circulating in the first absorption loop and a second absorption liquid is circulating in the second absorption loop. The air containing NOx is absorbed into the first absorption liquid to form an acidic solution comprising nitrates and nitrites. Off gases containing NO from the first absorption loop is fed to the second absorption loop, and the off gases containing NO are absorbed into the second absorption liquid having a lower pH.

Energy efficient process for producing nitrogen oxide
A process for producing NO gas from a feed flow of air or oxygen enriched air, by means of moving an electric arc through the air flow by using a magnetic field and AC or DC currents, in a reactor, wherein a pressure lower than 1 bar is applied, wherein the temperature in the exited arc is adjusted to be within the range of 3000 to 5000 Kelvin, and wherein the air flow is quenched by applying a spray of fine water droplets upstream or just downstream the arc, excess air feed or bypassed air to obtain a stable NO-containing plasma having a temperature below 2000 Kelvin.
