| Abstract: | A brief account is given of the circulation water system as well as the problem in the water quality of the first and third stage circulation water in the urea unit, the causes are analyzed, and technological renovation measures are put forward. After renovation, the quality of circulation water is greatly improved, especially, the Ca^2＋ and C1-content decreases significantly, and the cleaning frequency of the main heat exchange equipment prolongs from 2 months to 5 months. |
