One of our many achievements in the region is the successful commissioning of a large-scale Steam Methane Reformer unit for the YASREF refinery in Yanbu, Saudi Arabia, with a total hydrogen production capacity of 340,000 Nm3/hour. This is the first time in the Middle East that the hydrogen production for such a large refinery has been outsourced to a third party.


Metal fabrication

We have extensive expertise in metal fabrication across industries that produce steel, non-ferrous metal structures, vessels, cars, aircrafts, and others.

Via our ALKIG affiliate, we deliver reliable and competitive gas solutions to our customers, supplied via cylinders, bulk, pipeline distribution, and on-site production units. Our solutions cover three critical stages in the manufacturing cycle.

Cutting of metallic raw materials

  • Flame cutting using FLAMAL™, a range of oxygen and fuel gas (BMCG) that improve safety, quality and productivity
  • Laser cutting using LASAL™ to improve performance and reliability for high performance jobs
Meeting the needs of a highly diversified industry.

Air Liquide provides solutions along all stages of the glass production process, from melting to forming end products.


Glass is made in furnaces at very high temperatures with a process that requires constant improvement to meet the energy efficiency and environmental challenges posed by the manufacturing cycle.

Air Liquide provides solutions along all stages of the glass production process, from melting to forming end products through its ALKIG affiliate. To complete our offer, we deliver a competitive oxygen supply adapted to the needs of our customers, particularly through energy-efficient on-site oxygen generation systems.


Today, the metallurgy and glass industries are facing the dual challenges of making furnaces more energy and cost-efficient while reducing polluting emissions. In ALKIG, we support these industries with proven and patented combustion technologies based on burning fuel.

Glass polishing

Before a finished product can be packaged and sold, defects must be removed. We supply oxy-natural based gas and oxy-hydrogen based combustion technologies to polish the product surface and remove surface imperfections.

Glass edge melting

After the forming and before the annealing of glass articles, this operation aims to eliminate the cutting edges of products or marks made by the two half moulds on the article surfaces.

Carbon black deposit

Through deposition of a carbon black layer on the internal mould surface that is in contact with glass, carbon black deposit is an alternative method for mould lubrication.

Water and sewage treatment

Industries must reduce their pollution emissions and improve their processes for maximum reuse of water and materials, while complying with the reinforcement of environmental and sanitary regulations.

At Air Liquide, via our ALKIG affiliate, we master applications using gas technology to treat water, recycle metal, recover solvents, analyse air quality, and recover waste.

Drinking water

Carbon dioxide is used for calco-carbonic equilibrium management for remineralisation and pH control at desalination plants. Advanced treatment processes to answer stringent regulatory standards require oxidation and disinfection properties of oxygen.


The introduction of pure oxygen into biological basins with gas injectors, instead of using the traditional air blowing technology, helps industries comply with today’s strict regulations regarding wastewater discharge.

Sludge reduction

With innovative ozone (O3) solutions developed by Air Liquide, the biological sludge production and the energy and consumption of reactive products are reduced. Our customers manage their activated sludge process in a more efficient manner and produce 30% to 40% less sludge.

Scaling treatment

Replacing liquid chemical acids with the dissolution of carbon dioxide (CO2) in cooling water helps prevent or eliminate scale in the cooling circuits. Our expertise allows us to provide the most adapted treatment based on water characteristics and chemical treatments.

With more than 35 years of experience and references in water treatment, Air Liquide assists private and public companies with industrialized gas solutions to treat water.
Air Liquide has been a major player in food market, helping suppliers preserve food and extend its shelf-life and freshness by packaging it in protective atmospheres.

Food and Beverage

Air Liquide has developed innovative ALIGALTM food-grade gas solutions, compliant with HACCP (Hazard Analysis Critical Control Point) in order to meet the most rigorous health and safety standards. Whether in freezing, modified atmosphere packaging, product quality and flavour preservation, carbonation, inerting and/or throughout the processing and distribution chains, our goal in ALKIG is to guarantee the safety and high quality of the products for the end users, while increasing the productivity of our partners, preserving the quality and extending the product shelf life.

  • Modified atmosphere packaging (MAP):  to enhance appearance preserve organoleptic product’s characteristics while extending shelf life
  • Freezing and chilling: to enhance natural taste while minimizing dehydration
  • Cold transportation: keeping chilled and frozen products at the right temperature during transportation involving long distances and hot weather
  • Purging and inerting: protecting raw materials  (concentrates, edible oils…) from oxidation during the storage and the processing
