Purging fuel lines.
Purging fuel lines.
(OP)
Our site requires that we purge fuel lines (natural gas and butane) prior to any maintenance. We do this with N2 at the present time. We have a fairly good supply of CO2 on site. Is there a downside to purging fuel lines with CO2?

Whe laying up a power piping system it has always been a nitrogen blanket as this is inert...retards corrosion.

the only way to ensure that there are no gas pockets is to use a large amount of CO2 and sample ALL the high point vents to ensure that the CO2 concentration is higher than 97% in volume.
similar to the example cited by turboco1.
also, CO2 is much more expensive than N2... the main reason to use N2.

That is from --Static Electric Discharge Hazard On Bulk Oil Tank Vessels
International Safety Guide for Oil Tankers and Terminals (ISGOTT), advises against it but I don't have the manual here to quote from it.
More investigation is recomended before you do it
