Device for transfer of granular material between a low-pressure zone and a high-pressure zone (HP), comprising a first (1) and a second (2) chamber, each comprising a feed connection (14, 22) for granular material connected to the low-pressure zone, a second chamber (2), and an evacuation connection (18, 24) for granular material connected to the high-pressure zone, an interconnection circuit (26), and control means such that - during filling of the first chamber with the granular material, the transfer gas is sent into the second chamber (2), - after filling of the first chamber (1) with granular material, the transfer gas pressures between the first (1) and the second (2) chamber are equilibrated, - during draining of the first chamber (1), the first chamber (1) is fed with gas by the second chamber (2). |
