SPPE · System for Preventing Petrol Evaporation
Reduce gasoline evaporation at source.
A prevention-first fuel-storage technology designed to reduce evaporative loss within compatible applications—before vapour reaches downstream recovery controls.
Canadian company · Technical review for compatible fuel-storage applications
The challenge
Gasoline does not have to leave a tank to be lost.
Temperature, vapour pressure, filling, withdrawal, and storage conditions can move gasoline into the vapour phase. Those losses can carry volatile organic compounds, including benzene, into the wider emissions picture.
Working and loading · Vapour displaced as liquid enters or leaves storage.
Refuelling displacement · Vapour associated with vehicle refuelling.
Spillage · A separate liquid-loss category that should not be conflated with evaporation.
The SPPE position
Prevention before recovery.
Established vapour-recovery systems capture or return vapour after it has formed. SPPE is designed to address evaporative loss earlier, at source, while complementing the wider controls used across fuel storage, delivery, and refuelling.
Established controls · Manage vapour after it forms.
SPPE · Designed to reduce evaporation at source within compatible applications.
Applicable vapour recovery, pressure/vacuum controls, leak detection, tank integrity, fire and electrical safety, inspection, and environmental requirements remain in place.
Applications
One principle. Different operating contexts.
Gasoline stations · Underground and above-ground forecourt storage.
Bulk storage and distribution · Selected tanks, terminals, and distribution facilities.
Transport and mobile storage · Selected tanker, fleet, vehicle-tank, and marine applications, subject to engineering assessment.
Evidence
A useful result, kept in proportion.
A 2019 customer letter reported an approximately 83% reduction in evaporation losses at one SPPE installation.
Read with the result
This was a customer-reported result from one installation. It is not a universal performance claim, certification or guarantee. Results depend on application-specific conditions and require technical evaluation.
Official context, not SPPE performance evidence
Our research separates measured results, modelled scenarios, mass-emission factors, liquid throughput, and jurisdiction-specific controls. External sources explain the problem; they do not prove SPPE performance.
