TSA hydrogen purification
Temperature swing adsorption (TSA) removes water and other strongly held trace impurities from a gas by adsorbing them at ambient temperature and releasing them by heating the bed. Axsia Howmar supplies TSA…

DeOxo dryer
A DeOxo dryer is a purification package for electrolyser hydrogen. A catalytic deoxidiser reacts trace oxygen with hydrogen to form water, and a temperature swing adsorption dryer then removes the water, raising…

Specifying a DeOxo dryer for electrolyser hydrogen: the inputs that set the design
Hydrogen leaves a water electrolyser wet and carrying trace oxygen. A DeOxo dryer, a catalytic deoxidiser followed by a temperature swing adsorption (TSA) dryer, brings it to product specification. This paper sets…

Hydrogen purification
Hydrogen purification removes the other gases from a hydrogen-rich stream until it meets the purity its user needs. Four technologies do most of this work: pressure swing adsorption (PSA), temperature swing adsorption…
