Bubble point temperature of ammonia water
Thread Content
Request: First, I would like to know the bubble point temperature of ammonia solution. Secondly, I use a distillation tower to concentrate dilute ammonia water with an ammonia content of about 1.8% into ammonia water with a concentration of over 20%. Currently, the temperature throughout the tower is high; it is 113 degrees at the bottom of the tower, and it’s around 100 degrees at the top as well. The reflux volume is very low – even when no product is taken from the top of the tower, the reflux amount remains low. The pressure in the shell side of the condenser at the top of the tower remains fairly stable. I hope that master can give some advice
Currently, for the new technologies of refining, absorbing, and concentrating dilute ammonia solutions, ultra-gravity rotating bed technology can also be employed, such as the ultra-gravity rotating bed that is a patented product of Zhejiang University of Technology.
