The industrial supplier HyGear will install gas recovery systems in Saint Gobain's Germany facility.

HyGear has signed a contract with Saint-Gobain for its Hy.REC mix, which is used to recover the gas mixtures from the tin bath in float glass production.

Niels Lanser, Director of Marketing and Sales at HyGear, said: “The installation of our Hy.REC mix technology at Porz is the result of an extensive engineering effort from both companies over the past two years.

“We started out with basic designs based on tests of spent gases in Pisa and Herzogenrath plants and tailored the design further based on small scale tests in real life situations.

“From these tests, we learned that the potential savings were tremendous.”

The 10-year-contract will see HyGear recover, upgrade and recycle between 300 to 600 Nm3 per hour of spent industrial gas mixture consisting of hydrogen and nitrogen from the float line.

Thomas Schuster, Industrial Director at Saint-Gobain Glass Industry Germany, said: “In close cooperation with Saint-Gobain, HyGear has developed this highly interesting recycling system which gives us the opportunity to reduce our hydrogen and nitrogen consumption and therefore reduce our environmental impact as well as our costs.

“This capturing of innovations among the supply chain is completely in line with our groups sustainability programme and the groups World Class Purchasing strategy.”

By feeding the polluted gas mixture into HyGear’s Gas Recovery System, a fraction of the hydrogen and nitrogen can be recovered and reused as a new reductive gas mixture. This will improve product quality due to the increased atmosphere refreshment rate.
