A process for draining a residue (14) of liquid from the bottom (10a) of a tank (10) via a drain pipe (15) between the tank bottom and a pump (16), which is arranged at a level above the top (10b) of the tank, the pump (16) establishing a gas/liquid current in the drain pipe (15). At distinct levels (a1, a2) in the drain pipe (15) between the bottom (10a) of the tank (10) and the pump (16) gas medium is supplied to the gas/liquid current. A draining arrangement (13) has in the associated drain pipe (15) throttle nozzle openings (19a, 19b) for the supply of gas medium to the interior of the drain pipe (15). |
