How to separate urea from water? This post was last edited by lxq700918 on 2009-2-27 at 18:58.]
Utilize different boiling points for heating and flashing
The urea evaporation system is used to separate urea from water, primarily by employing negative pressure and heating.
I agree with the original poster’s view; a finished product with a moisture content of less than 1.0% is considered qualified.
Negative pressure flashing increases concentration and reduces water content
This isn’t what I want; I want to propose a method by which 500 tons of urea can be extracted per year from water containing 1% urea.
I was wrong; what I meant is to extract it from the treated wastewater containing 1% urea.
It’s a good idea, but it has no practical value or precedent. The urea low-pressure circulation system enables the recycling of low-concentration ammonia, urea, and carbon dioxide; these substances are fed directly into the high-pressure system using a high-pressure circulation water pump. It is important to adjust the water/carbon ratio. I don’t know what the brother is thinking. Do you want to develop new processes?
