The Nitrogen Cycle

A lesser amount of nitrogen is fixed from the atmosphere through reactions occurring in the gaseous emissions from volcanoes and from lightning discharges. This nitrogen is washed out of the atmosphere by rain and is added to the soil and water where it, too, can be used by organisms. Does this make sense to you yet? If not, continue reading on, it should be clearer soon. Human activities have a significant effect on nitrogen cycling. Production and use of nitrogen fertilizer, combustion of fossil fuels, and planting crops that fix nitrogen have unbalanced the previously stable relationship between fixation and denitrification. Gaseous industrial pollutants—abbreviated as NO x compounds—foul the air in many cities and wash out in sufficient amounts to constitute “acid rain” in some parts of the industrialized world. The nitrogen cycle can be understood most easily by looking at its separate parts: nitrogen fixation, ammonification, nitrification, assimilation, and denitrification.

 

The Benefits of On-Site Nitrogen Generation

Nitrogen gas provides numerous uses for various manufacturers. On-site nitrogen production is a sister function of compressed air, and can provide opportunities for efficiency such as cost saving for the manufacturers who initially used liquid nitrogen service.  Several manufacturers whose businesses critically require nitrogen gas are shifting from delivery of liquid nitrogen to on-site nitrogen generation. Considering the benefits of on-site generation, it becomes easy to understand and justify the change. The manufacturers can make savings of between 40 per cent and 80 per cent, depending on the current market prices of liquid nitrogen. Cost Reduction The cost of liquid nitrogen delivery in the industrial market usually ranges, depending on delivery locations and market costs. Shifting to the utilization of on-site nitrogen production can drop these cost to much lower figures irrespective of the user’s location. Even while factoring the capital costs incurred during on-site production, customers can achieve a return on investment in a period of between 9 months and two years. However, this will depend on the equipment that is currently present in the facility, such as air compressors, nitrogen generators, power, receivers, as well as any associated maintenance. The savings made are not inclusive of supplementary costs…
