Secondary containment monitoring system
A leak detection and prevention system adapted to continuously monitor the spaces of a double wall hydrocarbon fuel handling system comprising storage tanks, product lines, vapor recovery lines, tank vent lines, etc. The system establishes and monitors a resident gas-pressure within the interstitial space to monitor the integrity of the primary and secondary containment. Change in resident gas-pressure in excess of a calibrated vacuum flow rate or the presence of liquid in any monitored space initiates an alarm. Once an alarm is signaled, the product delivery system is shut down and an audio-visual alarm is activated in close proximity to operating personnel. An onsite service call by qualified personnel is required to return the product handling system back into service. A qualified service technician connects to a communication port on the system control module to evaluate the cause of the failure. The system utilizes vacuum pressure to monitor for containment breaches. Furthermore, the system utilizes a Bernoulli-based device to produce the monitoring vacuum.

Vapor recovery gas pressure boosters and methods and systems for using same
A gas pressure booster and a method for using it, which recovers fugitive gas emissions such as at atmospheric pressure, boosts them such as to the pressure level of the low pressure gas sink, and returns them to, e.g., the low pressure gas sink, in a single stage of compression. No electricity or cooling water is required. All gas used to drive the vapor recovery booster may be recovered and vented to the low pressure gas sink.In one preferred embodiment, the gas pressure booster includes a drive cylinder and a boost cylinder interconnected by reciprocating drive and boost pistons. The drive piston supplies force powered by a first gas stream within the drive cylinder which exhausts to a second gas stream at a lower pressure. Fugitive gas emissions may be captured and transported to the lower pressure second gas stream to eliminate gas discharged to atmosphere. The need for boosting a gas multiple ratios is eliminated, as the pressure of the fugitive emission vapor is equalized to the low pressure gas sink at the end of the piston suction stroke. Preferably, a four-way valve operating on differential gas pressure may be used to automatically actuate the reciprocating piston.

Fueling system vapor recovery and containment leak detection system and method
InactiveUS6901786B2Shut downDetection of fluid at leakage pointMeasurement of fluid loss/gain rateProcess engineeringLeak detection
A method and apparatus for monitoring a fuel vapor recovery system to determine if a leak condition exists in either the vapor return passage in a fuel dispenser or a common vapor return pipe. An air-flow sensor (AFS) may be located in the common vapor return pipe for all of the dispensing points at a service station, or in each fuel dispenser and coupled to the dispensing points of the fuel dispenser. The AFS registers vapor flow recovered by a dispensing point(s) that is returned back to the storage tank. If the AFS measures vapor flow when such dispensing point(s) coupled to such AFS is not actively recovering vapor, this is indicative of a leak in such dispensing point(s). The leak condition is reported by a tank monitor or other reporting system so that appropriate measures can be taken.

System and method for automatically adjusting an ORVR compatible stage II vapor recovery system to maintain a desired air-to-liquid (A/L) ratio
ActiveUS20070267088A1Effective recoveryLiquid transferring devicesPackaging under special atmospheric conditionsProcess engineeringFinancial transaction
A system and method for automatically adjusting an ORVR-compatible Stage II vapor recovery system to maintain the air-to-liquid (A / L) ratio within desired tolerances or limits to meet regulatory and / or other requirements. An air flow sensor (AFS) or vapor flow meter measures the amount of recovered vapor for a dispensing point to calculate the recovery efficiency of the system in the form of the A / L ratio. Volume or flow rate measurements can be used. ORVR fueling transactions are either minimized or excluded from the A / L ratio, so that the A / L ratio is not artificially lowered due to a blocked or altered recovery. The A / L ratio is then compared to a desired or nominal A / L ratio. Adjustments to the recovery system are made within prescribed safety tolerances if the A / L ratio differs from the desired ratio.
