Nitrogen purging is very common in most of the major breweries here in the UK, with financial and environmental benefits.
There are no major drawbacks compared to CO2 purging regarding oxygen control; however there are a couple of important issues with running beer into N2-filled tanks:
1. Because the tank is full of N2, there will be CO2 losses from the incoming beer, especially at the start of filling. This can be compensated by over a carbonating initially;
2. A certain amount of N2 will be absorbed into the beer. This tends to be quite low level so doesn't cause any problems with later transfers, package filling and dispense.
