The solution entering has a concentration of about 17,9% and is sub-cooled. By absorbing the ammonia gas its concentration rises till the saturation at this pressure: 19,5% and 31°C. The sub-cooling of the entering solution is sufficient so that further cooling is not necessary. In...
I have to absorb a pure ammonia gas at a pressure of 0,5 bar(a) by a subcooled solution of water and ammonia. In the past I have done it in a vertical column with a single sprayer at the top and the gas entering at the bottom. Now the flows are so large, 75 kg/s liquid (density 915 Kg/m3) and...
