Problems with carbon dioxide due to excessive consumption of fossil fuels and climate change are increasing interest in and demand for environmentally friendly energy sources. As a result, hydrogen has attracted attention as a new source of energy to replace fossil fuels. As the ultimate environmentally friendly source of energy, hydrogen is a pure unlimited source that does not create any by-products other than water. Recently, this natural gas has become more diverse in terms of use, including hydrogen fuel cell vehicles.
The most common method of producing hydrogen is the use of hydrogen as a by-product by separating hydrogen mixed gases formed during the petrochemical process. There is also a method of electrolysis that allows the production of hydrogen by aqueous electrolysis.
Hydrogen is a highly combustible gas to be cautious about and Compressed Hydrogen Dryers are normally custom made, to meet specific project requirements. Provided that the level of Oxygen (or any other reactive component) is reduced to a minimum in the gas mix, several versions are available, based on operating pressure, temperature and requested pressure dew point.
The type of regeneration is Heat Regenerated. Depending on the existence and type of available fluids to conduct this regeneration/cooling, we then adapt the components of the Hydrogen Dryer, to ensure that a strict minimum of gas will be lost (1-2% maximum when external dry gas is available for regeneration/cooling for instance).
H2-R-DRY is a Heat Regenerated Hydrogen Adsorption Dryer, with working pressures from 5 to 11 bar.
H2-HP-R-DRY is a Heat Regenerated Hydrogen Adsorption Dryer, with working pressures up to 50 bar.
