I would like to implement nitrogen recycling; I would like to ask about the minimum nitrogen level required for the nitrogen protection system
Thread Content
Dear colleagues, the company is currently focusing on energy conservation and emission reduction; all equipment is equipped with nitrogen protection, and the nitrogen carrying solvents is discharged after entering the RTO system through the exhaust pipe. The chief engineer wants to implement nitrogen recycling. I would like to ask about the minimum nitrogen content required for the nitrogen protection system. In other words, if the nitrogen content in the exhaust gas from the system is still high, is it possible to use a fan to compress and recycle a portion of that gas, as long as the concentration of flammable gases at the emission point is controlled? I’m not sure whether this approach is reasonable I would like to ask the experts here
Factors to consider for nitrogen recycling include nitrogen purity and cost-benefit analysis. If the nitrogen content in the emissions is high, recycling is feasible. However, it is necessary to ensure that no flammable gases are introduced into the protected area, and safety production requirements must be met. In accordance with ** and industry safety standards, it is necessary to keep the concentration of flammable gases in nitrogen below safe limits. A system can be designed to recover nitrogen of satisfactory purity, compress it using fans for reuse, and it should be equipped with appropriate detection and control devices to ensure the purity and safety of the nitrogen. This approach reduces costs and emissions, but a detailed technical and economic assessment is required before implementation. .

If recycling is to be done, the impact of exhaust pressure on the equipment must also be taken into consideration. Plus, there are equipment valves related to the setup, and the amount recovered is very small; it’s not worth the effort. I’m not sure what approach is being taken now, or whether purchasing liquid gasification is being considered. For reference.
It seems that the effort put in isn’t proportional to the rewards received
