Svolumens abziehen und den Überschuss nochmals durch den Grobreiniger wandern lassen, wobei diese Masse wieder einigen Schwefel aufnimmt. 



    PATENTANSPRÜCHE :      10   Verfahren zur Entfernung von Schwefelwasserstoff aus Gasen auf trockenem Wege, dadurch gekennzeichnet, dass man die Hauptmenge des Schwefelwasserstoffs in Reinigungstürmen, welche geformte Gasreinigungsmassen enthalten, die sich langsam zeitweilig oder stetig von oben nach unten durch die Türme bewegt, entfernt, während der restliche Schwefelwasserstoff mit loser Masse in einer nachgeschalteten Kasten- oder Turmreinigeranlage gebunden wird.

Remove the volume and let the excess wander through the coarse cleaner again, this mass again absorbing some sulfur.



    PATENT CLAIMS: 10 method for removing hydrogen sulphide from gases by dry means, characterized in that the main amount of hydrogen sulphide is removed in cleaning towers which contain shaped gas cleaning masses that move slowly, temporarily or continuously, from top to bottom through the towers, during the remaining hydrogen sulfide is bound with loose mass in a downstream box or tower cleaning system.

Claims

2. The method according to claim 1, characterized in that the coarse cleaning with molded mass is carried out at speeds of up to 500 mm / s, while the fine cleaning with loose mass is carried out in the usual way at 5-10 mm / s.

3. The method according to claims 1 and 2, characterized in that the gas is conducted in one or more coarse cleaners in cocurrent to the molded mass.

4. The method according to claim 3, characterized in that regeneration air is added to the gas stream in the coarse cleaners, which are operated with molded mass, at different heights of the towers and optionally also before entering the coarse cleaner.
