Electrolysis process description
Purpose of the plant is production of hydrogen and oxygen. A water
flow enters in the electrolytic cells where, through an electric
current, it happens the following electrochemical reaction.
H
2O -----1/2 O
2 + H
2
Hydrogen and oxygen, so produced, are stored separately in their
proper circuits and tanks. End user can use the required gas
quantity proportionally to his necessity : the generator provides
automatically to deliver the necessary gases (O
2 and H
2).
Production pressure of both gases is > 4 bar, and it is kept
constant by an electronic control equipment.
Plant Description -
Hydrogen Generator Model G 16/d
Generator G 16/d is composed by:
n 1 electrolitic cells with support slide and fixing belts in inox
steel. All connections and pipelines are in inox steel and chassis
in painted carbon steel. It is composed by:
- "Structural tank" in the lower level, in inox
steel for restraining of all liquids present in the generator in
case of accidental lack.
- Skid in carbonium steel, all painted and fixed to the "structural
tank" in order to guarantee a complete painting.
- Shell composed by four different compartments (A-cells, B
transformer, C- electrical and electronics parts, D- electro
pneumatics devices.)
Internal tanks in inox steel, with function of bi. phasic
separators, with condensators with air and liquid exchangers.
Furthermore there are present all the necessary devices for gases
treatment, like pressures balancing and regulation automatic
discharge system of condenses.
Pipelines and threaded connections in inox steel AISI304. Internal
exchangers by tube nest for coolings gases coming out from
separators groups.
n.1 process off-gas discharges device. The process off- gas of the
generator, i.e oxygen and hydrogen, will have an external discharge
from the cabinet by a proper pipeline
Plant control instruments
In the front side of the generator, inside a separate shaft
(insulated from production shaft of the degree IP65), it is
installed the electronic control panel with relevant PLC and power
interface: in the lower level there in another shaft (separated from
the first one) containing power transformer
