Definitions

  • the present invention relates to a vapour recovery system for the recovery of vapours from a vessel holding volatile liquid.
  • solvent recovery in industrial environments has required the use of an electrical power supply to provide a hot or cold heat source.
  • a hot source has to be protected from the flammable solvents to eliminate the possibility of ignition of the solvent.
  • such systems require extensive pipework for transportation of cooling water and difficulties often arise with the pumping of liquids to high levels, such as in vent stacks.
  • the supply of fuel, such as petrol to storage tanks at filling stations is one instance when a large amount of the substance may be lost as waste vapour. Vapour that is left in an "empty" petrol storage tank is fed back into the supply tank during re-filling of the tank. This is undesirable, particularly if the filling station is owned by a different company to the petrol supply tank since the station owner is paying for the petrol supplied but giving the supplier a tank full of vapour free of charge which may be condensed and re-sold. Additionally, an increase in vapour in a tank leads to a build up of pressure which is clearly undesirable.
  • the present invention provides a vapour recovery system for the recovery of vapour from a vessel holding volatile liquid, the system comprising a delivery conduit for delivering liquid to the vessel, the delivery conduit having a chamber with a hollow cylindrical member the top of which is connected to a supplementary pipe in fluid communication with the vessel, wherein any vapour in the vessel is drawn through the hollow cylindrical member into the supplementary pipe, and is returned to the vessel, the system being characterized in that the chamber comprises diverting means for diverting the flow of liquid to create a zone of negative pressure extending up the hollow cylindrical member, and in that the hollow cylindrical member extends from the top of the chamber and terminates within the diverting means of the chamber.
  • the liquid may be delivered to the vessel under the influence of gravity or by pumping means.
  • the movement of the liquid to create a zone of negative pressure is caused by diverting means.
  • the diverting means may be an angled member that extends obliquely to the normal flow of the fluid. More than one angled member may be provided.
  • the delivery pipe that delivers liquid to the tank is provided with an adapter that has the means for diverting the flow of liquid.
  • the diverting means may be formed integrally with the delivery pipe.
  • the diverting means imparts a swirling motion in the liquid flow thereby setting up a Coriolis effect. In this manner, a partial vacuum is created in the vicinity of the liquid that draws in vapour to result in the vapour being returned to the vessel in the liquid.
  • the adapter may be in the form of a cylindrical chamber that has means for attachment of the delivery pipe thereto and has means for attachment of a second pipe to deliver the liquid from the adapter to the vessel.
  • the chamber is provided with an inwardly extending rim around the perimeter thereof which is angled to constrict the flow of liquid that passes therethrough.
  • the rim is at an angle nf between 10° and 50°.
  • the chamber is also provided with one or more members, for example in the form of blades, that extend obliquely across at least a portion of the interior of the chamber. More preferably, three members are provided, preferably extending from the centre of the chamber to the perimeter thereof. Preferably, the members are angled at 10° to 40°.
  • the chamber may be constructed such that it has a narrowing therein whereby the flow of fluid therethrough is restricted and then expands following exit from the narrowing, for example by the provision of a chamber that has converging and then diverging sides.
  • the provision of an expansion point also assists in cooling of the fluid.
  • the hollow cylindrical member is preferably a hollow bar or rod and preferably extends past the top and base of the chamber.
  • the top of the hollow cylindrical member is preferably connected to a supplementary pipe that is in fluid communication with the vessel and the base of the hollow cylindrical member preferably extends into a second delivery pipe.
  • the negative pressure that is set up by the movement of the liquid that is caused by the diverting means provided in the chamber extends up the hollow cylindrical member thereby creating a partial vacuum therein to draw any vapour in the vessel along the supplementary pipe and down the hollow cylindrical member to be diluted in the liquid and returned to the vessel.
  • angled members and hollow cylindrical member may be separate components that may be installed in the chamber, or the chamber may have these features as an integral part thereof. Additionally, adequate seals should be provided where required to ensure sufficient retention of the negative pressure.
  • the supplementary pipe is provided with a control valve that allows vapour to enter the pipe once a predetermined pressure is reached.
  • An expansion valve may also be provided to have a cooling effect on the vapour and the contents of the vessel.
  • a control valve is provided within the chamber and is activated by the flow of fluid through the chamber.
  • movement of the valve is assisted by the provision of a piston balance.
  • the system referred to above is particularly suitable for use in relation to a liquid fuel delivery system that delivers fuel, such as petrol, from a fuel supply tanker to a storage tank.
  • fuel such as petrol
  • the system of the present invention may be used in conjunction with a further system for the recovery of vapour from a vessel holding a volatile liquid.
  • cool gas such as nitrogen
  • the cool gas may be supplied to a heat exchanger provided in the vessel or a vent stack to cool the vapour thereby assisting in its return to the vessel and reducing the pressure build up in the vessel.
  • the cool gas is provided by a vortex generator.
  • a vapour recovery system may be provided in any other part of a system that delivers volatile substances to a vessel, such as a drop tube that delivers fluid to a storage tank.
  • the aforementioned parts are constructed such as to create a zone of negative pressure as the fluid passes therethrough thereby drawing vapour into the path of the fluid.
  • the present invention utilizes the potential energy created by the delivery of a volatile liquid, such as petrol, to a storage tank.
  • a volatile liquid such as petrol
  • FIGS 1 to 7 of the accompanying drawings illustrate one embodiment of a vapour recovery system according to the present invention.
  • a petrol tanker 4 supplies petrol to a storage tank 6 at a filling station via a delivery pipe 8.
  • petrol vapour in the storage tank passes back up to the petrol tanker or is released to the atmosphere via a vent.
  • the petrol passes through a swirl-imparting chamber 10 or cage that induces a coriolis effect into the petrol as it is delivered into the tank via a pipe 12.
  • the swirling motion induced in the petrol creates a partial vacuum in the centre thereof that passes up a hollow cylindrical member 14 that is provided through the centre of the swirl-imparting chamber and extends as a pipette 17 from the base of the chamber into the pipe 12.
  • the hollow member 14 also extends from the top of the chamber 10 to a subsidiary pipe 16 that is in fluid communication with the storage tank 6.
  • the establishment of a partial vacuum in the member causes vapour to be sucked from the tank into the pipe and through the member 14.
  • the vapour is then passed back into the tank via pipette 17 by dilution in the petrol that enters through the pipe 12.
  • the subsidiary pipe 16 is provided with a control valve 18 and expansion valve 20.
  • the control valve is opened by the presence of a partial vacuum in the hollow member downstream thereto which acts on the diaphragm of the control valve. This allows any vapour from the tank that is drawn up the hollow member to pass through the expansion valve which has a cooling effect on the vapour. This further reduces the vapour pressure in the tank by condensing the vapour and/or assists in cooling the tank.
  • the control valve monitors the pressure such that the vapour recovery system is operation once a predetermined vacuum is achieved in the hollow member. Hence, the accumulative effect of the system is to take vapour from the space at the top of the tank into dilution in the petrol entering the tank which reduces the pressure in the tank.
  • the cooling effect also reduces the overall effect of the natural aspiration above the tank.
  • Figures 3 to 7 of the accompanying drawings illustrate the components of the vapour recovery system in further detail.
  • Figure 3 illustrates the swirl-imparting chamber 10 or cage that is a generally cylindrical vessel sealed at both ends and having a side branch 21 that is connected to the main delivery pipe 8.
  • the chamber has a cylindrical hollow member 14 extending through the centre thereof and has a cylindrical base component 22 that is relieved of material to allow petrol to flow therethrough (see Figures 3 and 4 ).
  • the base component has a central collar 21 for passage of the member 14 and the upper edge of the component is provided with an inwardly extending rim 24, the surface of which is angled, preferably 10° to 50° from the horizontal.
  • Three blades 26 are provided at spaced apart intervals extending from the central collar to the perimeter of the base.
  • the blades are orientated such that their upper surfaces extend obliquely to the path of travel of the petrol, preferably at an angle of 10° to 40°.
  • the petrol contacts these surfaces as it travels through the chamber and the obstruction to its flow imparts a swirling motion to the fluid.
  • the base component is also provided with a circular flange 25 extending from the lower edge thereof for attachment of the pipe 12 that delivers petrol into the tank.
  • the pipette 17 is connected to the base component by a nut 27 and washer 29 or other suitable fastening means, as shown in Figure 5 .
  • the pipette 17' may be provided with a shoulder 27' and circlip 29' in place of the fastening means for retention in the base component, as shown in Figure 6 .
  • the base component, chamber and/or central hollow member may be formed as an integral unit.
  • the angle of the rim and the blades of the base component may be altered, being adjusted to the required angle to ensure a maximum coriolis effect. Less or more than three blades may be provided across the opening of the base component but should be such as to ensure the creation of a sufficient coriolis effect without blocking the flow of petrol to too great an extent.
  • the diameter of the bore that extends through the hollow cylindrical member of the chamber may be varied in proportion to the height of the drop of the fluid and energy stored, preferably being in the range 3mm to 20mm in diameter.
  • the length of the member may be varied to maximize the vacuum within the coriolis area. This will be necessary for varying size of tanks.
  • FIG. 7 of the accompanying drawings illustrates one way of providing a tight seal between the delivery pipe and top 19 of the swirl imparting chamber.
  • a plate 23 is provided below the top plate 21 of the chamber and an O-ring 27 is provided between the two plates. The plates are screwed together by retaining screws 25 causing the O-ring 27 to be compressed and form a tight seal.
  • the components of the system may be made of any suitable material.
  • the swirl-imparting chamber, hollow member and base component are preferably made of metal, with the other pipes being of a composite plastics material.
  • Vapour from the tank may also pass up a pipe 40 into a vent stack 42.
  • a heat exchanger is provided that has a supply of cool gas, such as air or nitrogen.
  • the supply of cool air or other gas is preferably provided from a vortex generator, such as by means of the system described in International Publication WO 01/29491 A1 .
  • the supply of cool gas from the vortex generator is activated such that it is passed through the heat exchanger to cool the vapour and assist in returning the condensed vapour to the tank.
  • the aforementioned system preferably uses a source of nitrogen as the cool gas for aiding condensation of the vapour.
  • This also allows nitrogen to be introduced as a blanketing gas to the tanks.
  • the use of nitrogen instead of air reduces the amount of oxygen and moisture entering the system thereby making the system safer and minimizing corrosion of the tank.
  • the use of nitrogen as a blanket gas will also result in nitrogen being returned to the tanker.
  • the nitrogen may also be used for other applications on site that normally use a compressed air supply, such as the inflation of tyres and in car washes.
  • the system can include compressors 50, air purifying system and storage bottle 52 with relevant regulating equipment 54.
  • the regulator allows nitrogen into the tanks if the pressure drops below a predetermined set pressure, such as + 5 mbar.
  • FIGS 9 to 10c of the accompanying drawings illustrate an alternative vapour recovery system incorporated within a delivery pipe that supplies petrol from a petrol tanker to a storage tank at a filling station.
  • a delivery pipe 8 is attached to a chamber 10' having a hollow cylindrical member 14' passing through the centre thereof that is attached to a further pipe 12 that is in fluid communication with the tank.
  • the hollow member extends from the top of the chamber but terminates within the end part 312 of the chamber 10'.
  • a control valve 180 is provided that is situated in the path of the flow of petrol (indicated by the arrows in Figure 9 ).
  • the end part 312 of the chamber that surrounds the end of the member 14' is bevelled to provide with an area of reduced diameter that then slopes outwardly to provide an expansion point E.
  • FIGS. 10a to 10c illustrate the construction of the chamber in further detail.
  • the chamber comprises a venturi tube or pipe 14', a fluid catchment bush 300 attached to a valve cap 180a and body 180b by fastening means 301.
  • the valve body is also provided with a balance piston 302 having an allen cap screw 303, O ring 304 and split pin 305.
  • Return springs 306 act on the piston balance and valve.
  • the venturi pipe 14' and valve 180 are connected to an adaptor 307 for connection to a subsidiary pipe (not shown) via a bridging piece 308, cage retaining collar 309, split collar 310, cage legs 311 and an adapter piece 314.
  • An end piece 312 is provided at the base of the venturi pipe. This has inwardly tapering sides that then diverge to provide an expansion point E.
  • Negative pressure formed at the end of the pipe or tube 14' has a direct influence on the underside of the piston balance 302, assisting in operation of the shut-off valve reacting against closing springs 306.
  • the flow of vapour is controlled by a number of holes 316 around the circumference of the piston 302. These holes can be varied in size and number dependent upon flow and requirement on customer site. The object of these adjustments is to tune the unit to suit the height the fluid drops through unit 312 and the expansion point E whilst retaining the differential required to operate the balance piston 302.
  • valves 18, 20 shown in Figures 1 , 2 and 8 that are situated exterior to the chamber.
  • the valve is formed within chamber thereby providing a unit that can be easily and simply fastened onto a delivery pipe.
  • the provision of the valve in this location enables the valve to be activated in response to a flow of petrol, thereby ensuring that the system is shut off when no fluid is flowing. Additionally, the valve is operated using the energy of the petrol.
  • the provision of an expansion point formed as part of the chamber achieves a cooling of the fluid and vapour without the need for a separate expansion valve.
  • Figure 11 illustrates a vapour recovery system incorporated within the drop tube of the underground storage tank rather than the delivery pipe.
  • a region of the drop tube 400 is provided with a series of holes 401 around the circumference thereof and an inner tube 402 is provided within the drop tube in the region of these holes.
  • the inner tube has a restriction or narrowing 403 in a region thereof whereby petrol that flows through the inner tube expands following constriction through the narrow region thereby creating a zone of negative pressure. This in turn causes any vapour V to be drawn in through the holes and return to the storage tank in the petrol.
  • FIGS 12 to 15 of the accompanying drawings illustrate another vapour recovery system.
  • the system is provided to minimize the loss of vapour, such as petrol vapour, from a vehicle tank during filling of the tank at a filling station.
  • vapour such as petrol vapour
  • potential energy created by the motion of the petrol as it is dropped into the tank is used to form a partial vacuum or zone of negative pressure that causes vapour to be drawn into the path of the petrol, thereby diluting the vapour and returning it to the vehicle tank.
  • the vapour recovery system 100 is connected to the fuel dispensing nozzle 102 that is introduced into a fill port 104 of a vehicle in order to deliver fuel to the vehicle fuel tank 106 via a delivery tube 107.
  • a skirt 105 is provided around the end of the dispensing nozzle to form a substantially airtight seal between the nozzle and the fill port.
  • the vapour recovery system comprises a flow-diverting bush 108 that is connected to the delivery tube and has an inner tube 110 forming a main central channel 111 that extends through the entire length of the bush.
  • the intended outer end of the inner tube is provided with grooves 112 extending around the perimeter thereof that form multiple subsidiary channels. These channels are of a set width and depth, such as 1mm depth and 1mm width.
  • the middle section of the bush is provided with a sleeve 114 that has an angled flange or chamfer 116 at one end thereof that obstructs the path of fluid that flows along the subsidiary channels 112 thereby acting as a deflector to divert flow of the fluid around the outside of the bush.
  • the flange is set at an angle between 10° and 30°.
  • the end of the inner tube at the intended inner end of the bush is also provided with a chamfer 119. This diverts the flow of fluid in the main channel inwardly.
  • Pipes 121, 122 are attached to either end of the bush, the pipe 122 that is placed over the chamfered end of the inner tube being provided with a series of holes 118 that are substantially in line with the chamfered area of the tube.
  • the holes may be, for example, 0.3 to 1mm in diameter.
  • the fuel that passes through the inner tube of bush is constricted due to the presence of the chamfered area 119 at the end of the inner tube.
  • the combined effect is to reduce, or even possibly eliminate, the loss of vapour from a fuel tank.
  • FIGS 16 and 17 illustrate an alternative vapour recovery system that is suitable for a vehicle petrol nozzle and delivery pipe to reduce the loss of petrol vapour during filling of a vehicle petrol tank.
  • the nozzle 500 is provided with a narrowings 502 formed by a profiled throat valve at a point along the length of the tube 501 of the nozzle to restrict the flow of petrol as it passes through the tube.
  • the throat valve 502 is provided at a bend in the tube and causes a slight change in velocity which provides a temperature reduction at expansion point E. This results in a cooling effect at the point of entry of the dispensing nozzle into the vehicle tank which assists in preventing any loss of vapour that is trying to escape past the nozzle.
  • a further narrowing 503 for example in the form of a throat valve, part of which enters an inner tube or sheaf 504.
  • This causes an aerodynamic affect at the gap between the nozzle and the inner tube generating the vacuum source.
  • Holes 505 are provided through the inner tube and the tube 501 in this region. In this manner, fluid is directed into the inner tube provided in the end of the nozzle and then expands as it leaves the end of the nozzle causing a negative pressure to be set up such that any vapour V can be drawn into the flow of fluid through the holes 505 and returned to the tank in the petrol.
  • the expansion points E also effect a reduction in temperature of the fluid and vapour.
  • An insulated sleeve 506 is provided around the end of nozzle to assist in the cooling effect by preventing heat ingress through the nozzle wall. The cooling and condensing effects lower the pressure in the car tank.
  • Figure 18 illustrates an alternative arrangement within a fuel dispensing nozzle wherein an expansion point E is provided in the nozzle by means of a bevelled surface 601 within the tube 600.
  • an expansion point E is provided in the nozzle by means of a bevelled surface 601 within the tube 600.
  • the diameter of the tube is reduced and surrounded by a sleeve 602. Slots and holes 603 are provided through the sleeve and the tube. In this manner, the flow of fluid is restricted as it passes through the inner tube and then expands as it passes from the inner tube to the outer sleeve causing a region of negative pressure to be created.
  • FIG. 19 of the accompanying drawings illustrates an example of a vehicle filler cap 700 fitted with a vapour delivery system.
  • the cap is provided with an inner tube 702 extending from the end that contacts the nozzle N and a gap 704 is provided between the sides of the inner tube and the cap.
  • the inner tube is provided with chamfered sides whereby the diameter of the inner tube decreases in the region of the cap. Holes or slots (not shown) may also be provided through the sides of the inner tube. In this manner, the flow of fluid is constricted and then expands as it passes from the inner tube into the main cap thereby creating a zone of negative pressure that sucks in any vapour from the tank into the flow of fluid through the gap and/or holes.
