ON-SITE GAS TECHNOLOGIES
HyGear offers a package of on-site gas production technologies that make transportation of hydrogen, nitrogen and oxygen obsolete. We offer these technologies as packaged systems or turn-key as part of an integrated gas system for the entire metal production line.
A reliable supply of industrial gases plays a vital role in annealing and sintering processes. The most common are hydrogen and nitrogen for creating a stable gas atmosphere during annealing to improve the microstructure of steel products. In sintering processes, nitrogen and hydrogen-based atmospheres minimise the variations in atmospheric composition and dew point, both of which play a vital role in producing high quality products.
Currently, these gases are mainly supplied by electrolysis or road transportation of compressed or liquefied gas. Decentralised gas production by HyGear offers a safer, more reliable and cost attractive alternative to conventional hydrogen supply.
GAS SYSTEM ANALYSIS, DESIGN & DELIVERY
Since metal treatment processes vary in terms of process gas purity, flow patterns and volume requirements, HyGears involvement usually starts by analysing the customers requirements.
Based on this process analysis, we can engineer the optimal delivery system for industrial gases to your process. This usually combines some of our on-site generation products with conventional supply options.
Depending on the customers requirements we can extend our services to engineering, detailed design, construction and operation of the entire gas supply system.
HYGEAR'S PRODUCTS FOR THE METAL INDUSTRY
Hy.GEN® Hydrogen Generation by steam reforming of natural gas
HyGear offers on-site hydrogen generation systems based on highly efficient Steam Methane Reforming of natural gas. The produced hydrogen is mixed with nitrogen to create a stable atmosphere for annealing and sintering processes.
A variety of capacities is available for the metal industry. The Hy.GEN systems can be cascaded to fit the hydrogen demand of every sintering and annealing line worldwide.
N.GEN® Nitrogen Generation by PSA
Nitrogen can be generated on-site with HyGear's Pressure Swing Adsorption System. The highly efficient on-site nitrogen generator is based on HyGears extensive experience in PSA gas separation technology and gas processing systems.
The systems are flexible in capacity and supplied as an integrated skid including purification, compression and a PSA for air separation.
O.GEN® Oxygen Generation by VPSA
HyGear supplies very efficient Vacuum PSA systems to enrich the oxygen content of the combustion air.
This oxygen is used in oxy-fuel furnaces to reduce both overall energy consumption and emission of harmful species.
The O.GEN® is flexible in capacity as well as product purity. This allows HyGear to design the gas system for the optimal overall plant efficiency.
Hy.REC ®: Gas Recycling from the process
During sintering and annealing, the spent gas mixture is usually vented from the process. However, this waste stream has a significant value because of the relatively high hydrogen and nitrogen content.
HyGear supplies an integrated skid that recovers the vented gas from the upstream side. The system removes particles and purifies the mixture into high quality hydrogen and nitrogen that can be blended back into the gas system.
