Nuclear and conventional power plants

Hydrogen drying

nucleaireFor hydrogen-cooled alternators, the CHAUMECA adsorption dryers have been used for several decades to remove the water vapour that accumulates in the hydrogen as the alternator continues to operate. These bi-column dryers use damp hydrogen as a vector gas for the regeneration. There is therefore no gas loss and the dryer can function constantly. The operating pressure is typically 4 barg and the flow rates are frequently less than 30Nm3/h.

This equipment must meet the requirements of the nuclear industry if necessary and the ATEX standard.
