I know only one book  about Urea Process:

"Urea, its properties and manufacture" by George Tsei-Yu Chao, printed in 1967, well before modern plants. You will be lucky if you get hold of a copy. 


What you may find in other places are general descriptions of the process.


Urea is particularly challenging since it uses high pressure, it is corrosive, sampling is difficult, instrumentation (specially flow and pressure) are less accurate that in ammonia, and commercial simulators  are not accurate, with the only exception being VMGSim. 

Unfortunately what you ask for, that is, a book that you can read and get a fairly good knowledge about the technology is not yet published. You have to get it in pieces from articles, publications, senior engineers, the operating manual and seeing the plant running.


Another way to learn about Urea plant is by registering in  UreaKnowHow.com (*). I would say that at least half of the people that work in Urea plants have an account there. A few days ago, they published a good comparison between Saipem and Stamicarbon technology.


(*) I have no affiliation with them. It is just my opinion that the site is a good one.
