| titleOfInvention | Plasma nitrogen fixation with short path heat transfer |
| abstract | In this invention the fixation of nitrogen by means of an electric plasma is made more energy efficient by the transfer of heat energy rapidly and directly from the product gases of the plasma to the reactant gases entering the plasma thereby rapidly cooling the combined nitrogen products and freezing the equilibrium proportions of the products found in the plasma while using the heat removed from the products to assist in heating the reactants to plasma temperature to thereby conserve a portion of the electric energy otherwise required for heating reactants, the rapid and direct transfer of heat from the product mixture leaving the plasma to the reactant mixture entering the plasma being accomplished by a gas flow through the plasma that repeatedly reverses direction anbd by multipurpose electrodes having large internal surface area and other heat transfer characteristics whereby each electrode alternately absorbs heat from drawn in plasma gas and then transfers heat to reactant gas which it subsequently directs into the plasma region, the function of each electrode during each of two alternate periods being opposite that of the other electrode in that the function of each electrode is determined by the periodic direction of gas flow from one electrode to the other through the plasma, an electrode being a cooleer of product gas and an absorber of plasma heat when downstream to the reversible gas flow and then in a subsequent period functioning to give up its absorbed heat to reactant gases when it is upstream to the flow through the plasma. The preheating of reactants and the cooling of products by this double heat transfer that takes place at the very boundaries of the plasma itself increases energy efficiency and product yield. |
