Hydrogen Gas Generator
At SAM Gas Projects (P) Ltd, we design and build fully-automatic plants that generate hydrogen gas for different purposes. We are focused on offering our customers the best hydrogen generators with durability and productivity. Our hydrogen generators, hydrogen gas generators, industrial gas generators, are easy to operate and are maintenance free as well.
Hydrogen is obtained using two different procedures given herein:
• Water electrolysis process
• Ammonia cracking process
| By The Process Of Water Electrolysis
In electrolyzer, symmetrical conductive structure with anode in the middle and cathode at ends avoid the shortage of voltage. The improved sealing washer isolates hydrogen from oxygen used for many purposes. In this way, the separator, synthesizer, filter, cooler, cycling pump, tubes and valves are mounted on a skid for easy installation and transportation for smooth process.
This technique generates hydrogen gas through electrolysis (bipolar type) along with gas boosters and de-oxo units. When water is charged with electrical current, the electrolysis dissociates the elements of water (oxygen and hydrogen). In this connection, the amount of power consumed by these plants is 4.5 KW (per cubic meter of hydrogen).
Finally, the hydrogen obtained is collected in a hydrogen gas holder. It is kept for further use for processing. Though hydrogen obtained through electrolysis is 99.8% pure, yet the use of de-oxo units helps in purifying it further (up to 99.999%). This method is used by different industrial plants.
Industry applications of hydrogen gas generators :
- Chemical Industry : Hydrogenation process & animation synthiss.
- Oil & Gas Industry: Hydrogenation of edible oil& fatty acids.
- Heat Treatment Industry: Reducing protective atmosphare.
- Glass Industry: Protective atmosphare for casting float glass on molten metal bath.
- Electric Industry: Protective atmosphare for manufacture of eletronic component.

By Dissociation Of Ammonia
Typically an ammonia cracker unit produces cracked ammonia gas using the ammonia in anhydrous form from cylinders.Usually cracked ammonia contains around 75% hydrogen and 25% nitrogen.The product gas is dry and free of oxygen.
The production of cracked gas amounts to 2.63 nm3/kg of ammonia feed stock. The residual ammonia contents are less than 20 ppm and dew points are upto (-) 50 degC.
As certain application require the need of gas having very low residual ammonia contents
and low gas dew point.Here comes the PSA technology,cracked ammonia is passed through a special grade of dessicant in twin tower Pressure Swing Adsorption System(PSA type).
It has the properties of adsorption of nitrogen molecules at much faster rate than hydrogen molecules.
After this purification process,the residual ammonia contains generally fall below 3 ppm and dew point of gas shows considerable improvement up to (-) 80.
Technical Specification:
| Plant capacity | 1-500 nm3/hr | | Product Specification | Hydrogen : 99.5%
Nitrogen : up to .5%
Oxygen : Nil
Dew Point : (-)70
Pressure : 3.5to25 bar |
Application :
• Heat Treatment
• Edible Oil Industry
• Chemical & petrochemical Industry
• Chemical process Industry. |
