  • Dust pre-removal method in a dry moving bed type adsorption tower
    Patent number: 4744804
    Abstract: In a dry moving bed type adsorption tower using a granular adsorbent, for example, for removing SO.sub.x and NO.sub.x from waste gases, the granular adsorbent entering the adsorption tower is previously rinsed with a gas in a feed pipe for the adsorbent, thereby avoiding the need to install a dust collector at the outlet of the adsorption tower.
