Adsorption with heat compressed hydrogen dryer

Compressed Hydrogen Dryers (H2 Dryers) are designed for continuous separation of water vapour from compressed hydrogen, thus lowering its pressure dew point. 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). Characteristics of H2 dryers • operating pressure: 5 to 50 bar • operating temperature range (inlet): 1,5 to 40 °C • pressure dew point: -25 to -70 °C • flow rate: on request • design code for pressure vessels: EN 13445 • fluid group: 1
