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. 1

    Standing or breathing losses

    Vapour can be expelled as temperature and pressure change while petrol is stored.

  2. 2

    Working losses

    Filling and withdrawal displace vapour and change the conditions inside a storage tank.

  3. 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. 1

    Application review

    Understand the tank, fuel, throughput, operating environment and existing controls.

  2. 2

    Technical assessment

    Review compatibility, installation constraints, safety requirements and the proposed SPPE configuration.

  3. 3

    Pilot and validation

    Agree the measurement method, baseline, operating period and success criteria before deployment.

  4. 4

    Commercial pathway

    Develop the specification, quotation and implementation route from the validated application.
