| Abstract: | After urea plant and melamine system are put into joint operation,the melamine process ammonium carbonate recycled to urea increased water/carbon ratio of urea system,resulting in the decrease of urea conversion,load increases of medium and low pressure systems,as well as temperature and pressure exceeding of steam condensate system.Aimed at the existed problem,urea steam condensate system was revamped.After the revamp,the profits are optimized. |

| Keywords: | ammonia stripping steam condensate temperature and pressure exceeding revamping |
