高效填料塔在南化氮肥厂的应用

Application of high efficiency packing tower in nitrogenous fertilizer plant of Nanjing chemical industries group Co.,LTD

将高效填料塔应用于“含碳氨水集成分离技术”。氨回收率由５０％提高到９９％以上，全塔压降由５０ｋＰａ降至１０ｋＰａ，吨氨蒸汽消耗减少７５％以上。且流程简化。

The high efficiency packing tower was applied in isolation process of aqueous ammonia contained carbon dioxide. The application results indicated that the ammonia recovery increased from 50% to over 99%, the pressure drop of the tower reduced from 50kPa to 10kPa,and the steam consumption of 1t ammonia decreased by 75%. The process was simple and flexible.
