DOWEX Resins for Separation of Hydrogen from Liquid and Vapor Media

 
Hydrogen - H

Hydrogen can exist as a gas (H2), as a proton (the hydronium ion, H3O+) that is associated with other atoms or molecules and as part of a very wide variety of compounds. Hydrogen forms more compounds than any other element. The compounds that hydrogen will form can best be accessed in this index by the other elements in the compound.

Applications

Hydrogen, as a proton exists as solvated ions in protic acids. Acidity can be removed from water based solutions with an acid absorber like DOWEX™ M-43 anion exchange resin. Acidity can also be removed from organic solvents with DOWEX M-43 but the resin should first be dried to optimize the resins contact with the organic solvent.

Since H2 gas is often used in a compressed form, it is often contaminated with compressor lubricants. DOWEX OPTIPORE™ V503 polymeric adsorbents have been shown to work well to remove these compressor lubricants from compressed gas streams.
