Water Electrolysis Based Hydrogen Gas Plant
This method generates hydrogen through Electrolysis (bipolar type) along with gas boosters and de-oxo units. Electrolysis dissociates the elements of water (oxygen and hydrogen) by charging water with electrical current. The amount of power consumed by these plants is 4.5 KW (per cubic meter of hydrogen).The hydrogen obtained is collected in a hydrogen gas holder and is further used for processing. Though hydrogen obtained through electrolysis is 99.8% pure, the use of de-oxo units helps in purifying it further (up to 99.999%).
In an electrolyzer, the symmetrical conductive structure is provided with anode in the middle and cathode at ends that avoids the shortage of voltage. Though hydrogen obtained through electrolysis is 99.8% pure, the use of de-oxo units helps in purifying it further (up to 99.999%). The purified gas obtained after the process is used in heat treatment furnaces like annealing, sintering and as reducing furnace atmosphere.
