Commissioning of chemical plants

Our unit is a midstream unit in the system. I have a question: during the initial startup of the unit and when the utility systems are brought online, there is no protection for nitrogen; how can the nitrogen sealing system be activated for the air compressors and the steam compressors in the power plant?
Liquid nitrogen can be purchased externally; a vaporizer and nitrogen pipe connection hoses can be added
If air has no impact, an air compressor can be used to reach the appropriate pressure, and a buffer tank can be employed to achieve air sealing; if it does have an impact, then nitrogen must be purchased
