Determination of Emissions at a Petrol Station with the VACONOVENT-System
The VACQNOVENT® system, a novel system for emission reduction at petrol stations,
has been tested at a selected petrol station in Luxembourg in order to compare it with
commonly used vapor return technologies.
The determination of the total amount of emissions generated by car refueling with gasoline has been performed by three institutions skilled in environmental measurement techniques. Three different operating conditions were investigated. The vapor return rates employed were: 0, 100 and 150 %.
All three measuring campaigns clearly showed differences in ernissions when the operational vapor return system was compared to the shut down. The influence of increased vapor return rates up to 150 % on the total emissions of the petrol station could not be clearly verified because of the influence of various boundary conditions.
