Technology · petrol evaporation
A prevention-first approach to evaporative fuel loss.
Petrol vapour forms when volatile fuel is exposed to conditions that promote evaporation. SPPE is designed to reduce that loss within compatible storage applications, before vapour must be captured or recovered downstream.
Loss pathways
How petrol is lost as vapour
Evaporative loss is influenced by fuel temperature and vapour pressure, tank turnover, filling and withdrawal cycles, tank configuration and the controls already in place.
-
1
Standing or breathing losses
Vapour can be expelled as temperature and pressure change while petrol is stored.
-
2
Working losses
Filling and withdrawal displace vapour and change the conditions inside a storage tank.
-
3
Transfer and refuelling losses
Vapour is displaced as petrol moves through terminals, tankers, forecourt tanks and vehicle refuelling.
The scale varies by application; public emission-factor guidance provides context, not a single universal loss rate.
SPPE
Where SPPE fits
SPPE is designed to reduce evaporative loss at source within compatible storage applications. Its proprietary engineering is not disclosed on the public website; detailed evaluation is available to qualified operators and partners.
Established controls
Complementing established vapour controls
Stage I systems manage vapour displaced during petrol delivery to service-station tanks. Stage II systems recover vapour during vehicle refuelling. SPPE addresses the problem from a different point: reducing evaporation at source within the storage application.
SPPE is not a substitute for applicable regulation, safety duties or mandatory vapour-recovery controls.
Evaluation route
From application review to validation
-
1
Application review
Understand the tank, fuel, throughput, operating environment and existing controls.
-
2
Technical assessment
Review compatibility, installation constraints, safety requirements and the proposed SPPE configuration.
-
3
Pilot and validation
Agree the measurement method, baseline, operating period and success criteria before deployment.
-
4
Commercial pathway
Develop the specification, quotation and implementation route from the validated application.
Discuss the engineering context.
We can walk technical teams through the application requirements and available evidence without disclosing proprietary design information publicly.
