process by which nitrogen is obtained from air on a large scale?
air separation
bullet::::- low operating costs: by substitution of out-of-date air separation plants nitrogen production savings largely exceed 50%. the net cost of nitrogen produced by nitrogen generators is significantly less than the cost of bottled or liquefied nitrogen.









































bullet::::- environmental impact: generating nitrogen gas is a sustainable, environmentally friendly and energy efficient approach to providing pure, clean, dry nitrogen gas. compared to the energy needed for a cryogenic air separation plant and the energy needed to transport the liquid nitrogen from the plant to the facility, generated nitrogen consumes less energy and creates far fewer greenhouse gases.

nitrogen is a valuable substrate that can be utilized in algal growth. various sources of nitrogen can be used as a nutrient for algae, with varying capacities. nitrate was found to be the preferred source of nitrogen, in regards to amount of biomass grown. urea is a readily available source that shows comparable results, making it an economical substitute for nitrogen source in large scale culturing of algae. despite the clear increase in growth in comparison to a nitrogen-less medium, it has been shown that alterations in nitrogen levels affect lipid content within the algal cells. in one study nitrogen deprivation for 72 hours caused the total fatty acid content (on a per cell basis) to increase by 2.4-fold. 65% of the total fatty acids were esterified to triacylglycerides in oil bodies, when compared to the initial culture, indicating that the algal cells utilized de novo synthesis of fatty acids. it is vital for the lipid content in algal cells to be of high enough quantity, while maintaining adequate cell division times, so parameters that can maximize both are under investigation.
