Full speed ahead for HyGear’s Hy.RECmix at Saint-Gobain’s production facility in Porz, Germany


Arnhem – HyGear, a supplier of industrial gases through on-site generation and recovery technology announced the signing of a contract for the supply of Hy.RECmix gas recovery systems with Saint-Gobain (SGO.PA), one of the world’s largest flat glass manufacturers.

The results of the initial testing of the Hy.RECmix in the facility of Saint-Gobain in Herzogenrath, Germany, have been proven successful by both teams of engineers in Saint-Gobain and HyGear. With these positive results, Saint-Gobain has chosen to implement the full system in another one of their facilities located in Porz, Germany.

In this ten-year contract, HyGear will recover, upgrade and recycle between 300 and 600 Nm3 per hour of the spent Industrial gas mixture of hydrogen and nitrogen from the float line. This will reduce Saint-Gobain’s demand for new gas significantly and as a result reduces costs and environmental impact.

“The installation of our HyRECmix technology at Porz is the result of an extensive engineering effort from both companies over the past two years” comments Niels Lanser, HyGear’s Director of Marketing and Sales. “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 there is the potential savings is tremendous,” further explains Niels.

“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 program and the groups World Class Purchasing strategy,” said Thomas Schuster, Industrial Director of Saint-Gobain Glass Industry Germany

Advantages of gas recycling

The Hy.REC system is developed to recover the gas mixtures from the tin bath in float glass production and metal industry. Currently, significant amounts of the hydrogen-nitrogen gas mixture are – in combination with pollutants – left at the exit of industrial processes and left unutilised. The Hy.REC system can recover this used and polluted mixed gas atmosphere from the process in a very cost-effective way. By feeding the polluted gas mixture into HyGear’s Gas Recovery System, a significant fraction of the hydrogen and nitrogen can be recovered and reused as a new reductive gas mixture. This reduces costs and improves the product quality due to the increased atmosphere refreshment rate.
