Professions in hydrogen exhaust treatment and fuel cell

Toplus addresses hydrogen exhaust with measures of safe, decarbonisation and recycling.
In many industrial processes, hydrogen is used as a protective gas with less than 1% consumed in the reaction, while 99% is discharged with mix of other gases which eventually vent to scrubber for either combustion or dilution.

Most H2 is wasted
Burning H2 is prone to generate NOx.
H2 emission is harmful to environment.

Toplus develops and manufactures innovative hydrogen purification and recycling (HPR) equipment which is the world’s first HPR equipment having SEMI S2 certification. In the cases that hydrogen need to be discharged, Toplus’ novel dehydrogenizer product line, based on Low Temperature Hydrogen Oxidation (LTHO) technology, can eliminate hydrogen by converting H2 into H2O.

Enhancing safety of workplace, hydrogen accumulation in a confined area must be tackled.
Hydrogen, the lightest gas, is prone to leak through the smallest gap and should not be allowed to collect in confined spaces or poorly ventilated areas. Toplus DHC is a cycle type dehydrogenizer and works out of the box without power required, it can convert H2 into H2O to avoid hydrogen accumulation. DHC is used in couple with ventilation and H2 sensor, thus providing safer workplace.

Toplus ECHP purifies hydrogen exhaust by sperating nitrogen with safe and high efficiency.
Many hydrogen exhaust gases contain nitrogen which is not easy for speration when performing purification.
Toplus Electrochemical Hydrogen Purifier (ECHP) is designed to purify hydrogen exhaust by separating nitrogen gas under ambient pressure and low temperature, the recycling efficieny can be up to 80%.

For hydrogen to be a net-zero solution, emission should be tackled eco-friendly.
Hydrogen in air is flammable over the range of four to seventy-five percent concentration, vented hydrogen is traditionally treated by either combustion or dilution, but both methods are not ideal eco-friendly. Based on Low Temperature Hydrogen Oxidation (LTHO) technology, Toplus’ DHP series pipe type dehydrogenizer is designed to eliminate hydrogen in safe, zero CO2/NOx emission, low energy consumption and capable of heat recycling. The product allows hydrogen to be converted into water by mixing hydrogen with oxygen of air and then passing through the catalyst reactor to ensure residual hydrogen concentration lower than 4000ppm. Reaction takes place at temperature lower than 100 degree Celsius and ensures that a flame cannot occur.

Low operation temperature (<100)
Zero CO2/NOx emission, H2O is the only byproduct
DRE > 98%, Residual H2 < 4000 ppm* (10% LEL)

Besides the traditional combustion or dilution, you have better way to treat vented hydrogen.
Toplus DHP pipe type dehydrogenizer provides an ambient-temperature, zero-emission, energy-saving and eco-friendly solution of hydrogen elimination.
The heat generated from hydrogen oxidation can be recycled, it can help you to save electricity bills and reduce carbon emissions.
