CARBAMIDE SYNTHESIS COLUMN Russian patent published in 2001 - IPC

Abstract RU 2173212 C1

FIELD: synthesis of carbamide from ammonia and carbon dioxide at high temperatures and pressures. SUBSTANCE: carbamide synthesis column includes vertical cylindrical shell lining on inner surface made from corrosion-resistant material, mass-transfer unit and reagent inlet and outlet pipe unions; mass-transfer unit is made in form of nozzle, receiving and mixing chambers and diffuser connected in succession and fitted on reagent inlet pipe union; they are enclosed in perforated casing. Optimal result is obtained when the following requirements are satisfied: perforated casing in made in form of overturned cylindrical sleeve; perforated casing is connected with shell by means of retainers. EFFECT: increased productivity of column; increased conversion of carbon dioxide. 3 cl, 1 dwg
