GLASS INDUSTRY


The use of industrial gases in manufacturing of glass products has increased significantly over recent years. Gases play important role producing high-quality industrial glass products economically while reducing emissions. Be it manufacturing of glass containers or float glass or glass fibres or picture tubes, gases of right specification and optimum cost impacts product quality and profitability of the manufacturers.

Airgases Projects provides to glass industry a custom designed Air Separation Plant based on cryogenic technology producing high purity oxygen or low purity oxygen and  high purity nitrogen & argon required for various applications. We can also provide low purity oxygen plants based on VPSA technology and nitrogen from PSA / membrane technology where volume of gases required is rather low and lower purity product  is acceptable.  Our team  can also offer cryogenic liquid storage, pumping and vaporisation ( SPV) systems where liquid oxygen, nitrogen or argon is purchased from external sources The liquid thus purchased is stored in cryogenic storage tanks and then pumped to required pressure or directly supplied through pressurised tank and vaporised to ambient temperature before being used by customer for its applications.

Some application examples:

Nitrogen application in inerting and purging for:

  • Float glass furnace
  • Protection of vacuum tubes  in manufacturing and storage

Oxygen application in combustion and chemical oxidation for:

  • Increasing performance and productivity of furnace through better lance performance
  • Glass blowing
  • Reducing environmental emissions
  • Forming of neon light tubes in desired shape
  • Coating of  ceramic products
  • Flame polishing of porcelain products with Oxy-fuel burners

Argon application for low reactive gases, high inert capability, thermal conductivity and solubility in water and oils

  • Fill incandescent light bulbs along with nitrogen
  • Fill fluorescent lamps
  • Improved insulation in windows

We at Airgases Projects undertake a detailed simulation and analysis of the oxygen/nitrogen/ argon consumption profile, including peak consumptions, to work out most cost effective solution for the customer on “ total cost of ownership” basis. Airgases Projects also offers various gas application systems required for glass industry such as oxygen control modules , oxygen enrichment systems and full distribution network.
