Toplus’ solution on the treatment of hydrogen exhaust
Toplus’ hydrogen purification and recycling (HPR) solution is designed to purify hydrogen exhaust in industrial process which traditionally is discarded due to limitation of legacy technology. The purified hydrogen can be recycled and sent back to the front end of process, or being used for power generation.
The HPR solution includes two types of equipment: Electrochemical Hydrogen Purifier (ECHP) and Porous Ceramics Adsorbent Purifier (PCAP); both of which can work under normal pressure without the need to compress hydrogen.
The ECHP is used to remove N2, while PCAP is used to remove substances other than N2, such as H2O, O2, NH3, VOCs,… etc. Depending on the composition of exhaust gases and purification requirement, they can be used alone or in combination.
In the cases that exhaust hydrogen needs to be discarded, legacy treatments may not be ideal eco-friendly and safe, such as high temperature combustion is prone to generate NOx. Toplus develops and manufactures innovative dehydrogenizer product line based on low temperature hydrogen oxidation (LTHO) technology, it adopts a flameless safe operation by converting H2 into H2O leading to residual hydrogen concentration lower than 4000ppm.
The LTHO product line has two series including DHC cycle type and DHP pipe type.
DHC is used to eliminate a small amount of leaked hydrogen in a space. It is used in couple with qualified ventilation and hydrogen detection equipment to avoid the accumulation of hydrogen in poorly ventilated area, so as to enhance safety.
DHP is used to eliminate the exhaust hydrogen from pipeline. It allows the hydrogen to be oxidized to a safe level before being discharged, and if required the heat generated during the oxidation process can be recycled.
