Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air, or by mechanical means using gaseous air (pressurised reverse osmosis membrane or pressure swing adsorption). Nitrogen gas generators using membranes or pressure swing adsorption (PSA) are typically more cost and energy efficient than bulk-delivered ...
2 ημέρες πριν · Nitrogen is a nonmetallic element and the most abundant gas in Earth's atmosphere. It is essential for life, and it has many industrial and chemical applications, such as fertilizer, refrigerant, and inert atmosphere.
Nitrogen is commercially recovered from the air as ammonia, which is produced by combining nitrogen in the atmosphere with hydrogen from natural gas. Ammonia is converted to other nitrogen compounds, the most important of which are urea (NH2CONH2), nitric acid (HNO3), ammonium nitrate (NH4NO3), and ammonium sulfate [(NH4)2SO4].
Nitrogen is a colourless, odourless gas that makes up 78% of the air by volume. It is essential for living things and has many industrial applications, such as making fertilisers, nitric acid, nylon and explosives.
