中小氮肥厂CO_2脱除工艺技术选择

Selection on CO2 removal process in medium and small nitrogen fertilizer plants

从基本原理、工艺特点和技术经济等方面对中小型氮肥厂采用活性ＭＤＥＡ、苯菲尔、碳酸丙烯酯３种脱ＣＯ２方法进行了比较，认为不仅对于新建装置选用活性ＭＤＥＡ法脱ＣＯ２具有较强的竞争力。

Three methods of active MDEA, Benfield and propylene carbonate for CO2 removals are usually adopted in medium and small nitrogen fertilizer plants. The three methods were compared from fundamentals, process characterizations and technical economy. It is considered that selecting active MDEA method in new commercial installation or for transforming outmoded enterprises will make a remarkable profit.
