Gases

AMMONIA (NH3)
Ammonia, or azane, is a compound of nitrogen and hydrogen. It is a colourless gas with a characteristic pungent smell. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilisers. It either directly or indirectly, serves as a building block for the synthesis of several pharmaceuticals and is used in many commercial cleaning products. It boils at −33.34 °C (−28.012 °F) at a pressure of one atmosphere, so the liquid must be stored under pressure or at low temperature.

Applications

  • Pharmaceuticals: Ammonia has diverse uses in chemical processing, from pH control to caramel colouring.
  • Refrigeration: Due to its thermodynamic properties, Ammonia continues to be a highly efficient refrigerant in large industrial processes such as ice-making and food processing.
  • Heat treatment: Disassociated ammonia is used to form atmospheres for metal treating processes such as nitrating and annealing.
  • Emission control system: Ammonia is used to control emissions. It is also used in Effluent Treatment Plant for controlling water pH.


CARBON-DI-OXIDE (CO2)
Carbon dioxide (CO2) is a colourless, odourless, non-flammable and slightly acidic liquefied gas. It is heavier than air and soluble in water. It is produced industrially by using sources of CO2 obtained through processes in the petrochemical industry, or by burning natural gas in cogeneration processes.

Applications

  • Food: Carbonated beverages, gasification beverages packaging, freezing and cooling.
  • Deburring and grinding.
  • Neutralization.
  • Metal fabrication applications.
  • Catering.
  • Medicine: Mixes metabolic.
  • Foamed Plastics: supercritical extraction.


NITROGEN (N2)
Nitrogen is a chemical element with symbol N and atomic number 7. It is the lightest pnictogen and at room temperature, it is a transparent, doorless diatomic gas. Many industrially important compounds, such as ammonia, nitric acid, organic nitrates(propellants and explosives), and cyanides, contain nitrogen.

Applications

  • To preserve freshness of packaged or bulk foods
  • In incandescent light bulbs as an inexpensive alternative to argon
  • Dried and pressurized, as a dielectric gas for high-voltage equipment
  • To manufacture stainless steel
  • On top of liquid explosives as a safety measure


OXYGEN (O2)
Oxygen (O2) is an active, life-sustaining component of the atmosphere; colourless, odorless and tasteless. It is highly oxidizing, reacts vigorously with combustible materials, has a low boiling / condensing point: -297.3°F (-183°C), is approximately 1.1 times heavier than air and is slightly soluble in water and alcohol. Commercially, oxygen is prepared by the fractional distillation of liquid air.

Applications

  • Steel industry
  • Manufacture of metals like copper and lead
  • Manufacture of chemicals like nitric acid, hydrogen, hydrogen peroxide epoxyethane, chloroethane
  • To burn off carbon deposited on the fluid catalyst used in the catalytic cracking of gas oil
  • Sewage and industry effluent treatment
  • Paper pulp bleaching
