<p>This invention relates to a process of continuously conveying granular solids from a first zone with a pressure of 4 to 16 bar through a descending line and via an ascending line to a second zone with a pressure which is lower than in the first zone by 3 to 15 bar, by means of a gaseous medium. To ensure that the pressure between two regions can be reduced at low cost and with little maintenance effort when continuously conveying granular solids, a gaseous medium (9) is injected into a tube through an upwardly directed nozzle (6) at the point where the granular solids are conveyed through a descending line (2) into an ascending line (3).</p> |
