This report prepared on Material balance on manufacture of urea. We have applied the material balance on the entire process like material balance on reactor,stripper, vacuum evaporator etc. From material balance we conclude that how much amount of ammonia, carbon di oxide and water uses in the manufacture of urea & how much amount are losses during the entire process. From the process we also evaluate that how much amount ammonium carbamate are recycle back to reactor and at last we find how conc. of urea goes on increasing during the process,the conc. Of urea after the prilling process is about 98%.
