If (and it's a pretty big if) there's a significant oxygen outflow
this could be fed to a fossil fuel station (or for that matter any
fuel burning station) to increase the efficiency - you wouldn't need
to heat all that nitrogen.
If there isn't - well, releasing small quantities of oxygen is
hardly a major risk to the environment.

Wouldn't be small if the thing went industrial. Try breathing pure
oxygen at atmospheric pressure. Your lungs will be ****ed in short
order.

What were you thinking of doing with the 80% odd nitrogen still hanging
around there?

It would take an awful amount of "process" to change to other 20% by a
significant amount
