Nitrogen inertization of digesters and fermenters
Make your systems safe with nitrogen instead of oxygen
Inerting is a technique that consists of replacing oxygen with an inert gas, such as nitrogen, to reduce or eliminate the risk of combustion, explosion, or the development of other dangerous phenomena.
In particular, the inerting of digesters and fermenters is a necessary procedure to ensure safety during maintenance, cleaning, or repair of these systems.
The digester and fermenter inerting service provided by Franchini Servizi Ecologici involves several phases.
Preparing the digester or fermenter
Before starting the inerting process, it is necessary to prepare the digester or fermenter to prevent the release of inert gases. In this phase, the following operations are performed:
- Closing all openings in the digester or fermenter;
- Ventilation of the digester or fermenter to eliminate oxygen;
- Checking the digester or fermenter for leaks.
Inerting the digester or fermenter
Inerting is performed by injecting nitrogen into the digester or fermenter through a distribution system. The nitrogen level is monitored to ensure it is sufficient to reduce the oxygen concentration below a safe limit.
Inerting Verification
After inerting is complete, a check is performed to ensure the digester or fermenter is completely inert. At this stage, the following operations are performed:
- Measurement of oxygen concentration in the digester or fermenter;
- Leak test of the digester or fermenter.
The nitrogen inertization service for digesters and fermenters at Franchini Servizi Ecologici is performed by qualified personnel and with the use of cutting-edge equipment and technologies. The company is able to offer a complete and safe service, ensuring maximum protection of workers and the environment.
