Method&Equations

The inlet air is mixed with the inlet white liquor, the reaction takes place:
2H2S + 2O2 -> H2O + S2O3-- + 2H+
The heat of reaction determine a temperature rise, the economizer inlet water cools the reaction mixture to the user specified temperature.
The reaction mixture is flashed gasses are living the equipment trough the Vent stream, and the liquid trough the Liquor_Out stream.
