Methods for removing scaling from ammonia vaporization towers
Thread Content
At present, scaling in ammonia evaporation towers is a long-standing problem in the soda ash industry; the addition of lime milk during the ammonia evaporation process causes scarring to form on the internal trays and walls of these towers. Upon analysis, over 99% of it is calcium sulfate. Now, apart from manual cleaning and cleaning with high-pressure water guns, are there any other good methods for removing it? I welcome everyone's suggestions.
At least, there is no more efficient method yet.
What are your work stress level and temperature, respectively? Thank you!
Ammonia-free processes already exist; there is no need for an ammonia evaporation step, and no ammonia is introduced into the entire system, which improves the environment and reduces costs.
I’m hearing about this for the first time; is there any specific details? Thank you!
There is a new technology for producing soda ash using an ammonia-free process; no ammonia synthesis plants are required, and the investment in soda ash production facilities is reduced by 40%. The raw materials used are industrial salt and limestone (which provides the carbon source), while the products obtained are soda ash and calcium chloride.

I washed it, and the result was great. If you are sure it is calcium sulfate scaling, use a calcium sulfate cleaning agent with a pH of 7.0±0.1; it is non-corrosive, reacts rapidly and intensely, and removes calcium sulfate at a rate visible to the naked eye. If you’re interested, I can send you samples for free to test; I guarantee they’ll work well for you. Of course, the prerequisite is that you must be sure the scale sample is calcium sulfate.
Calcium can be removed before ammonia vaporization, online cleaning can be increased, or anti-clogging trays can be designed.
