In a fuel vapour recovery system, fuel vapour is drawn off and converted to liquid fuel. The system comprises a compressor, individually closable inlets for the fuel vapour and leading to an inlet duct of the compressor, a return duct by way of which an outlet of the compressor communicates with the inlet duct, and a control device which controls communication between that outlet and the inlet duct via the return duct in dependence upon the number of the inlets which is open. The system further comprises a tank, a first sensor which serves to detect when liquid water in the tank attains a predetermined height in the tank, a second sensor which serves to detect when liquid fuel in the tank attains a higher, predetermined height in the tank, a first device responsive to the first sensor and serving to cause removal of at least part of the liquid water from the tank when the liquid water attains the first-mentioned predetermined height, and a second device responsive to the second sensor and serving to cause removal of at least part of the liquid fuel from the tank when the liquid fuel attains the higher, predetermined height.
A method comprising storing liquid fuel in a liquid fuel storage tank, withdrawing liquid fuel from said storage tank, dispensing withdrawn liquid fuel into a fuel tank of a vehicle by means of a liquid fuel dispensing device, drawing off fuel undesirably in gaseous form at said dispensing device, converting the fuel in gaseous form to a liquid form, and leading the liquid fuel converted from a gaseous form to said dispensing device in such manner as to bypass said storage tank.
A method of converting an organic substance in gaseous form to a liquid form, comprising compressing the organic substance in gaseous form in a compressing stage, and condensing the compressed organic substance in gaseous form in a condensing stage.
An apparatus for converting an organic substance in gaseous form to a liquid form, comprising a compressor which serves to compress the substance in gaseous form, and a condenser which serves to condense the compressed organic substance in gaseous form.
A module comprising a separation tank, a first sensor which serves to detect when a heavier fluid in said tank attains a predetermined height in said tank, a second sensor which serves to detect when a lighter fluid in said tank attains a predetermined height in said tank, and a pressure controller for controlling pressure in apparatus external to said module.
A liquid fuel dispensing station comprising a liquid fuel storage tank, a liquid fuel dispensing arrangement serving to dispense liquid fuel into vehicle fuel tanks and to draw off fuel undesirably in gaseous form, a liquid fuel delivery line extending from said storage tank to said dispensing arrangement, a converting arrangement which serves to convert the fuel in gaseous form to a liquid form, a first-path, for said fuel in gaseous form, from said dispensing arrangement to said converting arrangement, and a second path, for the liquid fuel converted from gaseous form, from said converting arrangement to said delivery line other than by way of said storage tank.
A method of transforming fuel vapour into liquid fuel and separating air therefrom, comprising sucking an uncompressed mixture of fuel vapour and air into an apparatus through a vapour recovery filling nozzle;
