Is natural gas or nitrogen better for pressure holding?

The unit buffer tank was originally designed to be pressurized with natural gas, but is now pressurized with nitrogen. Therefore, nitrogen inevitably enters the vented plant gas. The refinery gas from the unit’s backend is also used for heating furnace combustion and as a raw material for hydrogen production units. So I was wondering if using nitrogen would have any effect?
Generally, there won’t be any impact
It has no significant impact, and you can switch to nitrogen, change the pressure control of the buffer tank to interval control, which results in less waste gas being emitted. Common solutions
The LNG gasification process can be used for power generation or propulsion (exclusive technology)
