Abstract:
A system for dispensing hydrocarbons from a storage tank comprising:a pump (2) followed by a liquid/gas (3) separator connected to a device for measuring liquid volume (4) upstream of a dispensing valve (5);a circuit for recovering hydrocarbon vapour, connected to the dispensing valve (5) to pick up hydrocarbon vapour at an outlet of a tank (6) being filled by the dispensing valve, the dispensing valve (5) being connected to a vapour suction pump (10), the vapour suction pump having an output connected to the storage tank (1),a control unit (11) connected to the device for measuring the liquid volume (4) and to a vapour flow controller (9) as well as the vapour suction pump (10) to control the flow of vapour depending on the rate at which liquid is dispensed by the dispensing valve (5); anda vapour/liquid separator (8) having a receiving chamber (81) for collecting liquid, the vapour/liquid separator being mounted in the vapour recovery circuit upstream of the vapour flow controller (9), the receiving chamber (81) connected to a bleeding pipe (85) having an inlet fitted with a non-return valve (86).
