Bei einer vor kurzer Zeit erstmalig in großtechnischem Maßstab ausgeführten Schwefelwasserstoffdruckwäsche

des Schwefelwasserstoffs mit weniger Waschflüssigkeit bewirkt werden kann und somit weniger Waschwasser
entsäuert zu werden braucht als bei einer

steht darin, daß die kleinere Waschwassermenge auch
besonders sorgfältig entsäuert wird, da ein Druckentsäurer mit einem höheren Wirkungsgrad arbeitet 2
als ein Normaldruckentsäurer.In a recently carried out for the first time on an industrial scale hydrogen sulfide pressure wash, the washing water running off is in

This process has the advantage that the washout
the hydrogen sulfide can be effected with less washing liquid and thus less washing water needs to be deacidified than with one
Laundry under normal pressure. Another advantage is 20
it says that the smaller amount of wash water also
is deacidified particularly carefully, since a pressure deacidifier works with a higher degree of efficiency 2 than a normal pressure deacidifier.

This would z. For example, there is no need for steam to run a deacidifier in the circuit via a deacidifier, which equates to ammonia water, ζ. B.
