Gas recovery for metal processing

Metal powder processes rely on high volumes of hydrogen, argon and helium. Once the gas has passed through the process, a considerable share is vented or flared, so you keep buying fresh gas to replace volume that is still usable. HyGear's Hy.REC® system captures that vent gas, purifies it and returns it to your process line, reducing the volume of fresh gas you need to purchase or generate.

Cut gas consumption with on-site vent gas recovery

Protective atmosphere hydrogen is expensive to source, transport, and store. Once it leaves your process as waste gas, that cost is permanent. Hy.REC® changes that by recovering, purifying, and recycling the hydrogen that would otherwise be lost, so it re-enters your process at the required purity level.

The result is a marked reduction in gas supply volumes, lower operational costs, and a smaller carbon footprint for your production process.

How the Hy.REC hydrogen recovery system works

HyGear combines multiple in-house core technologies to engineer a hydrogen recovery system matched to your specific process conditions and gas quality requirements. Depending on the inlet gas composition and the required hydrogen purity, we configure the most suitable combination of technologies, including pressure swing adsorption (PSA) and temperature swing adsorption (TSA), to maximise recovery rates and system performance. We have a robust system, so we can handle gas flows with high dustloads.

The modular design allows Hy.REC® to be configured for a wide range of metal processing applications, with gas flexible recycling capacities and hydrogen purity up to 5.0 grade (99.999%).

Why metal processing facilities choose Hy.REC®

HyGear’s Hy.REC® systems are in operation at metallurgy facilities across multiple countries. Proven technology, high up-time, and a containerised, compact footprint make integration with existing plant infrastructure straightforward. Atakaş Steel in Turkey is among the companies that rely on HyGear hydrogen technology in their metal processing operations.

High return on investment from hydrogen recycling

The economics are direct. Every Nm³ of hydrogen recovered is a Nm³ you do not purchase. For facilities with high hydrogen throughput, the reduction in gas supply costs delivers a high return on investment and a short payback period.

Configured to your gas quality requirements

No two metal processing lines are identical. HyGear engineers each Hy.REC® system around the specific inlet gas composition and the purity your application demands, so the recovered hydrogen consistently meets your process specification.
