小氮肥厂碳化尾气中氨回收及碳化软水的水平衡是困绕该厂的难题,虽然作了多方面探索,如改造塔的结构型式效果差,投资大。我公司开发的传质过程中有热反应板式塔,不但解决了碳化水平衡,而且稀氨水排放达标。使经济、社会、环境效益明显,为小氮肥厂节能降耗创造了条件。 Ammonia recovery in the small nitrogenous fertilizer plant carbonization and water balance of carbonated soft water is a difficult problem around the plant, although made many exploration, such as the transformation of the tower structure type effect is poor, large investment. My company developed a heat transfer plate heat transfer process in the tower, not only to solve the carbonated water balance, and dilute ammonia discharge standards. The economic, social and environmental benefits are obvious, creating conditions for saving energy and reducing consumption of small nitrogenous fertilizer plants.
