【Abstract】 The water balance of first absorbing tower in urea pro du ct and its influence factors were studied. The amount of water and recovered amm onia of condensator were calculated, and it was helpful to keep the water balanc e of system. The good ratio of H₂O/CO₂ in converter improved the conversion of carbon dioxide.更多还原
