As an extension of its ammonia dissociator capability Thermal Dynamix also builds systems specifically for producing reasonably pure hydrogen from anhydrous ammonia.
The process begins with the dissociation of ammonia vapor into a gas comprised of its constituent elements of 25% nitrogen and 75% hydrogen. That gas is then compressed and forced into a molecular sieve where the nitrogen is stripped away from the hydrogen.
The resulting hydrogen is approximately 99% pure and is delivered for use at pressures generally in the 80 - 150 psi range.
Because the stripped nitrogen contains approximately 7%-10% hydrogen it's not generally useful and is discarded.
