ADDITIONAL EVAPORATION AND CONDENSATION LOOP FOR AN UREA PRODUCTION PLANT, METHOD OF MODIFYING AN EXISTING UREA PRODUCTION PLANT USING SAME AND USE THEREOF

摘要

According to the invention, an additional recirculating evaporation and condensation loop passing from and to the dust scrubbing section is introduced to a plant for the production of urea comprising conventional sections for synthesis and recovery, for evaporation and condensation, for urea finishing and for dust scrubbing. This recirculating loop results in a more favorable energy consumption of the plant.
