Quasi-equilibrium plasma energy efficiency

The set of equations describing energy and mass transfer in quasi-equilibrium plasma-chemical systems are analyzed in the next section to determine the influence of transfer phenomena on energy efficiency.

The difference between vibrational and translational CO2 temperatures (Tv > 7 o)results in a maximum energy efficiency increase to 60% even in the case of the quasi-equilibrium balance of direct and reverse reactions (Evseev, Eletsky, Palkina, 1979), because direct endothermic reactions are mostly stimulated by molecular vibration, whereas reverse exothermic reactions are mostly stimulated by translational temperature (see the Fridman-Macheret a-model in Chapter 2). This efficiency corresponds to the case of super-ideal non-equilibrium (TV > To) quenching of the CO2 thermal plasma dissociation products (Potapkinetal., 1983). 

In this relation, Xj(p, T) = rii/no is the relative concentration (molar fraction for ideal gases) of the i component of the mixture of the H2O dissociation products /, is the total enthalpy of component i no is the total density of the quasi-equilibrium gas mixture. Based on (5-136)-(5-138), the final formula for the calculation of the energy efficiency of water dissociation and hydrogen production in thermal plasma with absolute quenching of the process products can be presented as...
