| Abstract: | A presentation is given of the process flow and special features of the 40 kt/a urea unit based on CO2 stripping, and an analysis is made of its design indices and assessment results of the production technology. In 2000 the unit was technologically updated, with the addition of a medium pressure decomposition absorption system, and after the revamp the urea capacity reached 190 t/d. In October 2004 it was renovated by using dual stripper in parallel, the ammonia consumption for a ton of urea dropped to 575 kg, and the daily output of urea reached over 245 t. |
