This work investigates the absorption of NH3/H2O in a PHE, which has a weight concentration of 96%. Being different from normal absorption systems. Diagram for ammonia/water mixtures in A2 format (16.5 x 23.4'') as a color print, calculated according to the IAPWS-Guideline 2001 from Tillner-Roth and Friend. Since the repulsions on the bond pairs in H2O molecule are greater than that in NH3 the bond angle in water is less than that of ammonia. qLDX - NH3, H2O Gas Analyzer. qLDX.
