4.2 Configuration
4.2.1 Fuel processing system
The hydrogen generator shall be provided with a fuel processing system.
The fuel processing system may include the following steps:
— fuel clean-up, in which the fuel may be filtered and/or desulfurized;
— primary conversion, in which the fuel is reacted mostly to hydrogen, carbon dioxide, and carbon monoxide by means such as steam reforming, auto-thermal reforming, or catalytic or non-catalytic partial oxidation;
— water-gas shift conversion, in which carbon monoxide reacts with steam to produce additional hydrogen;
— purification, in which carbon monoxide and other impurities are removed from the hydrogen-rich product stream;
— conditioning, in which the stream temperature and humidity are adjusted to levels suitable for the type of device using the hydrogen;
— tail gas combustion, in which unreacted fuel and unused hydrogen are burned in a catalytic or non- catalytic manner prior to their release to the environment.
4.2.2 Fluid management system
The hydrogen generator shall be provided with a fluid management system.
The fluid management system may meter. condition and process fluids, or adjust the fluid pressure for use within the hydrogen generator. These fluids may be reactants such as air (oxidant), fuel, water (or steam), intermediate product streams, or utility fluids such as inert gas and heat transfer fluids (water, oil). The fluid management system may include complex sub-systems such as steam generators, compressors and water treatment units.
4.2.3 Thermal management system
The hydrogen generator shall be provided with a thermal management system that provides cooling and heat rejection to maintain thermal equilibrium within the hydrogen generator, and which may provide for the recovery of excess heat and assist in heating the unit during start-up.
NOTE The thermal management system uses heat and mass exchange networks to minimize external heating and cooling requirements as well as water consumption and energy losses by linking hot and cold process streams in a thermodynamically advantageous way.
4.2.4 AutomatIc control system
The hydrogen generator shall be provided with an automatic process control system that regulates the efficient interaction of all components in order to maintain the process parameters within the limits specified by the manufacturer, without manual intervention.
NOTE The automatic process control system may comprise mechanical, hydraulic, pneumatic, electrical, electronic, programmable electronic, and computer hardware/software elements.
4.2.5 Electrical system
The hydrogen generator shall be provided with an electrical system.
The electrical system may comprise circuits and devices that regulate and distribute electrical power
within the hydrogen generator.AS 16110.1 pdf download.
