ADDITIONAL CONCENTRATION OF CONVENTION AND CONDENSATION FOR THE INSTALLATION OF UREA PRODUCTION, THE METHOD OF MODIFICATION OF THE EXISTING INSTALLATION OF THE PRODUCTION OF UREA WITH ITS USE AND ITS APPLICATION

摘要

According to the invention, an additional recirculation loop of evaporation and condensation extending from the dust removal section and to it is introduced into the urea production plant, which contains the traditional synthesis and recovery, evaporation and condensation sections, final processing of urea and dust removal. This recirculation circuit leads to a more favorable energy consumption of the installation.
