Assessment method BREF:

A) Emission reduction potential

B) Operability

C) Applicability

D) Safety

E) Waste, energy, cross-media

Operational score OS = A * (B+C+D+E)

Financial score:

Capex = Capital Expenditure (F)

Opex = Operational Expenditure (H)

Cn=F * H

Overall score = OS * Cn

New tanks and terminals

External floating roof tanks are part of the

focus in reducing emissions

Tank conversions, reducing emissions

Replacing an external floating

roof by an aluminium dome roof

with internal floating roof

Steel External

Floating Roof (EFR)

Aluminum Dome with

Volume gained per tank: app. 5,000 m3

Aluminum Dome and IFR:

• New Tanks - Reduced tank size for given working capacity

• Existing Tanks - Increased working capacity
