  3. DESCRIPTION Chemical hydrogen generator GIP™ 3 • Set of accessories: • 1 bucket13 litres • 1 Straight funnel • 1 bent funnel • 1 silicon basket3 m3 • 1 shovel • 1 poker • 1 brass brush • 1 spanner12” • 1 neoprene protective gloves • 1 protective goggle • 1 earthing device Closing assembly And draw off valve

  4. OPERATING PRINCIPLE • The process of hydrogen production with the GIP™ 3 generators is based on the attack of silicon by the caustic soda in aqueous solution under pressure and high temperature. • Its production per cartridge is 3 m3 of hydrogen (measured in conditions at 15 °C and 760 mm of mercury). • The caustic soda undergoes the action of pure silicon in autoclave. • Pressure is produced by the reaction itself, which is not reversible. • A local rise in temperature enables the liquid to reach a temperature high enough to compensate fully the retarding action of the pressure and to insure that the pure silicon is completely attacked. • The hydrogen is stored into the cylinder at high pressure.

  5. HYDROGEN GENERATOR LAYOUT • The hydrogen generator has to be used outside. • In case of use inside, the building shall be equipped of: • Sufficient dimensions to permit an easy handling, • Ventilation openings at the top and bottom to ensure effective replacement of ambient air, • Hydrogen approved artificial lighting, • Appropriate fire safety measures, • Drinking or raw water supply, • Pit for the elimination of the residues, • Earth point for earthling connection. Chemicalhydrogengenerator type GIP™ 3

  6. USE OF THE EQUIPMENT • EARTHING • Earth rod shall be embedded of 1 meter minimum into the ground. • Earthing wire (4 mm² – length = 20 m) between the earth rod and the cradle of the generator • Earthing wire (4 mm² – length = 10 m) between the earth rod and the inflating sleeve • Earthing wire (4 mm² – length = 1.1 m) between the cradle and the draw off valve after having introduced the reactive products into the generator and firmly screwed the closing assembly. • CHARGING • Make sure that the generator is empty and dry. • Fill completely the filter basket with granulated silicon. • Mix the GIP™ alkaline cartridge with the powder silicon into the bucket. • Pour the powdered mixture into the cylinder of the generator. • Place the basket into the cylinder of the generator. • Pour 13 litres of water into the cylinder of the generator and screw immediately after the closing assembly.

  8. USE OF THE EQUIPMENT • PRODUCTION D’HYDROGÈNE • Set the generator in vertical position and shake during 10 seconds. • Check if the closing assembly is firmly screwed. • Open the draw-off valve during 2 minutes in order to • de-aerate the generator. • Wait until the hydrogen production rises 80-100 barg. • Shake again the generator during 10 seconds. • Wait until the end of the reaction. • MAIN CRITERIA • Approximate reaction time 45 minutes • Min. / Ave. / Max. temp. elevation 200°C / 250°C / 280°C • Min. / Ave. / Max. pressure elevation 90 b./ 130 b./ 160 b. • Bursting pressure 185 b. • Hydrogen production 3 m3 theoretical Chemicalhydrogengenerator type GIP™ 3

  9. USE OF THE EQUIPMENT • HYDROGEN DRAWING OFF • Hydrogen may be used immediately after the reaction. • Hydrogen pressure • Apparatus cool Approx. 100 barg • Apparatus hot Approx. 130 barg • EMPTYING AND RINCING • The residues have to be drained completely from the cylinder into the bucket. • The residues have to be mixed with 50% of raw water for total elimination. • The cylinder has to be washed and cleaned with raw water.

  10. POSITION TO USE Position of the generator during the reaction Generator in charging position Position of the generator in draining and rincing Preparation of the generator before draining

  11. PERIODICAL OPERATIONS • BEFORE EACH REACTION. • Grease the threaded neck of the cylinder. • Grease the threaded plug of the closing assembly. • AFTER EACH REACTION • Drain the residues contained inside the cylinder. • Wash the internal and external parts of the cylinder. • Clean the filter silicon basket. • ONCE A WEEK • Grease the wheels and trolley axes. • Check the state of the plastic washers of the closing assembly. • ONCE A YEAR • Check the tightness of the draw-off valve and replace it if necessary. • EVERY SIX MONTHS • Replace the plastic washer of the closing assembly. • Replace the silicon basket filter. • Check the state of the safety copper strip; replace if necessary. • EVERY FIVE YEARS • Retest the GIP™ hydrogen cylinder Chemicalhydrogengenerator type GIP™ 3

  12. INSTRUCTION FOR GIP™ CYLINDERS REPROOF TEST • Periodical pressure proof tests every 5 years at 1.5 time the service pressure. • The proof test has to be witnessed by an expert from the competent National Department. • Proof test certificate shall be issued after the stamping of the cylinder. • Proof test has to be performed with a hydraulic pump. • Proof test has to be made in case of visible defects on the cylinder such as : • Notch or groove 5% deeper than the thickness of the cylinder, • Lamination (fold, overlap, entrapment, flaking of the metal), • Punch marks, • Collar not fixed, • Grinding recess or suspect stain. • Systematic reject has to be decided in case of visible defects on the cylinder such as : • Projection on the surface of the cylinder visible to the naked eye, • Dent greater than 0.5% of the outside diameter of the cylinder, • Crack or tearing of metal, • Damage due to fire, • Arcing or blow torch damage.
