Introduction • An air separation plant separates atmospheric air into its primary components nitrogen, oxygen, argon and other rare inert gases.
Air Products has produced over 2000 air separation plants and currently owns and operates over 300 air separation plants

Properties of Oxygen • Colourless • Odorless • Gas phase(Oxygen changes from a gas to a liquid at a temperature of -182.96°C) • Allotropes –Dioxygen, Ozone • Slightly soluble in water • Denser than air • Supports combustion but does not burn • Occur in many compounds including water,co2,iron ores
Properties of nitrogen • • • • •
Colourless Odorless Inert diatomic gas Molecular nitrogen condenses at −195.79 °C. Occur in many industrial compounds, such ammonia, nitric acid, organic nitrates
Applications Oxygen • • • •
Metal manufacturing Chemicals Petroleum refineries Glass and Ceramics Industry • Pulp and Paper Manufacturing • Health Care
Nitrogen • Nitrogen blanketing • Manufacturing and construction • Multi industries • Food and beverages • Rubber and plastic industry • Health care
Available technologies •Cryogenic process •Pressure Swing Adsorption •Membrane separation
Cryogenic distillation • The most common method for Air separation is Cryogenic distillation • Cryogenic Air separation is the preferred technology for producing very high purity O2 and N2
