    摘要: A vent system for a fuel storage tank and a pressure vacuum valve (PVV) module (110) for use with such a vent system are disclosed. The vent system defines a vent path (30) from the fuel storage tank (10) to atmosphere, comprising an elongate vent pipe (33) which extends vertically to a rain cap (300) located at the upper end of the vent pipe, and a pressure vacuum valve (PVV) (130) located in the vent path between the lower end of the vent pipe (33) and the tank (10). The pressure vacuum valve (130) maintains the vent path in a closed condition unless the pressure in the tank is above or below a predetermined pressure. By separating the PVV from the rain cap and placing it between the lower end of the vent pipe and the tank, it is possible to site the PVV at an accessible level for maintenance. The PVV (130) is located in a PVV module (110). The vent path deviates from the axis of the vent pipe to the pressure vacuum valve which is located in the module (110), in a position offset from the vent pipe axis. The module also includes an auto shut-off valve (120) and a condensate collector.

The primary pump is positioned to cause fluid to pass from the filter input port to the primary filter output port. The secondary pump(s) is/are positioned to cause the air component within the fuel vapor duct to pass through the air-permeable partition to the secondary filter output port. The additional filter input port is coupled to the secondary filter port. The additional secondary filter output port is coupled to the air exhaust port. The additional secondary pump is coupled to the additional filter assembly and is positioned to cause the air component within the additional fuel vapor duct to pass through an additional air-permeable partition to the exhaust port.

    摘要: A method is described for the preconditioning of an adsorbent, such as activated carbon, prior to charging the adsorbent into a reaction vessel of a vapor recovery system. The method includes the steps of (1) treating the adsorbent in order to establish in the adsorbent a residual heel of vapor of the type to be subsequently adsorbed in vapor recovery processing and (2) adding the treated and, therefore, preconditioned adsorbent to the reaction vessel of the vapor recovery system. In this way vapor recovery system downtime is significantly reduced.

    摘要: A process for reclaiming and recycling gasoline vapor that collects in the headspace (27) of gasoline storage tanks (11) at retail service stations comprises sealing the tank against ingress of atmospheric gases, introducing a selected inert gas into the storage tank as the liquid gasoline is extracted therefrom to establish an inert gas/gasoline vapor mixture in the headspace (27) of the storage tank (11), periodically recovering the inert gas/gasoline vapor mixture from the storage tank, and processing the recovered mixture to condense the gasoline vapor to liquid gasoline, wich is removed for subsequent use.

    摘要: An attitude sensing arrangement for triggering a shutoff mechanism on a fuel dispensing nozzle 18 comprising a rolling element 86 placed inside a non-cylindrical chamber 84 that is sealed with a plug 88 such that the rolling element 86 may move freely inside the chamber 84. A vacuum sensing path 76 passes from a sensing port 74 in the nozzle spout 72, through a vacuum sensing tube 70, into the non-cylindrical chamber 84, and into a venturi-generated vacuum chamber 68. The attitude sensing arrangement is configured such that the rolling element 86 blocks a shutoff port 92 in the non-cylindrical chamber 84 when the nozzle 18 is raised past a certain shutoff angle. When the vacuum sensing path 76 is blocked by the rolling element 86 in this manner, the shutoff mechanism closes the main fuel valve 48.
