Innovent: Revolutionising Vent pipes
Before joining Risbridger and the complex yet exciting world of engineering, a petrol station was just that – a place to refuel, grab a coffee and get going again.
So what’s changed? Now, I find myself looking around at every detail. I analyse the fill points, dispensers, above ground storage, vent stacks and layout. I ‘d go so far as to say that I have become somewhat of petrol station enthusiast!
Recent developments here at Risbridger have won us the APEA innovation award for our Innovent.
For those not in the know, Innovent is a low access venting solution for petrol stations, and as a result of our developments here I have become particularly interested in the vent stacks on petrol stations.
These vents allow air to be drawn into the tanks as liquid is dispensed, providing an emergency pressure release for the tank vapour recovery system which is crucial. Guidelines in the APEA Blue Book state that the vent pipes should not be less than 4 metres above ground level.
Below is a reference from the APEA blue book.
The difference that Innovent can make can be seen here in the photo taken below on a recent trip to Denmark with our distributer, LD Handel.
The difference in vent stack layout, but most of all height, is clearly apparent. This challenges all of my previous preconceptions that the height of the vent stack was almost set in stone, to allow effective dispersal of any discharged vapour that can create a flammable atmosphere.
Are the rules different in Denmark?
