Gas-liquid mixture in a line (10) from, say, a petroleum well is pumped out through a line (19), the pumping being effected by a system comprising a pump (17) and vessels (1, 2, 3). In operation each vessel undergoes intake, stand-by and compression/delivery phases. During the intake phase of each vessel, mixture is sucked thereinto by the pump 17, communication between the mixture line (10) and the suction side of the pump being established by opening of the appropriate valves (4-9, 11-16). At the same time the contents of another vessel is expelled to the delivery line (19) by liquid delivered by the pump, again by opening of the appropriate valves. <IMAGE> |
