Concentrations of the H2S and SO2 in the TailGas in response to high concentrations of oxygen in the air oven (for the four oxygen concentrations in the air entering to the new design) have minimum amount of their own. But the SO2 concentration in the TailGas (At high concentrations of oxygen input into the reaction furnace) is a maximum. Concentration of the CS2 in the TailGas, in the oxygen concentration equal to 21% molar is lower with than other concentrations. Concentrations of the S2, S3, S4, S5, S6, S7 and S8, in the concentration of oxygen in the air inlet to the reaction furnace above 70 mole%, were minimal
