When water vapor pass into the liquid phase, vapor phase hydrogen sulfide and ammonia as the sub-components down to the equilibrium vapor pressure, so it still liquid into gas.

When water vapor into the liquid-vapor in the photos, because hydrogen sulfide and ammonia group of sub-low vapor pressure on balance, it is still a liquid into vapor phase.

When the steam passes over the liquid phase, because in the vapor phase the hydrogen sulfide and the ammonia component differential pressure is lower than time the balance vapor tension, therefore it still changed over to the gas phase by the liquid phase.

When the water vapor into liquid phase, due to the partial pressure of hydrogen sulfide and ammonia in vapor-phase fraction below the equilibrium vapor pressure, so it still turn by liquid phase to gas phase.

Inject liquid phase as vapor, because vapour take a fancy to sulphur fen of component of hydrogen and ammonia force down the vapour pigeonhole on balanced time, so it still changes over to the gaseous phase from liquid phase.
