métaux à recycler - Air Liquide

Metal recycling

Are your metal processes generating combustible impurities such as those found in poor quality scrap metal? Air Liquide's oxycombustion solution can allow you to use them to power an oven. The conventional power supply (fuel or natural gas) then takes over after total combustion of the impurities. This solution has several advantages:

- Achieve significant fuel savings
- Promote the use of lower quality scrap metal, which is therefore less expensive
- Improve productivity and reduce hazardous combustion gas emissions
