Abstract:
1. A process for producing NO gas from a feed flow of air or oxygen enriched air, comprising moving an electric arc through the air flow by using a magnetic field and AC or DC currents in an arc and plasma disc reactor, wherein a pressure lower than 1 bar is applied in the reactor, wherein the temperature in the arc is adjusted to be within the range of 3000 to 5000 Kelvin, wherein the air flow is quenched by applying a spray of fine water droplets upstream or just downstream of the arc, excess air feed or bypassed air to obtain a stable NO-containing plasma having a temperature below 2000 Kelvin, wherein the arc and plasma disc reactor comprises a shell and tube heat exchanger, and wherein the heat exchanger tube ends are used as anodes for rotating plasma arc cones with corresponding cathodes placed opposite to each tube.
