OPERATING PRINCIPLE
Chemical hydrogen generator
type GIP™ 3

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.
HYDROGEN GENERATOR LAYOUT
Chemical hydrogen generator
type GIP™ 3

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.
USE OF THE EQUIPMENT


Chemical hydrogen generator
type GIP™ 3
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.


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.

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.


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
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 :






Systematic reject has to be decided in case of visible defects
on the cylinder such as :


