摘要
介绍了柳州化肥厂脱ＣＯ２装置由苯菲尔法改为活化ＭＤＥＡ法的工艺改造依据。改造后提高了净化气（Ｈ２、Ｎ２）和再生气（ＣＯ２）的纯度、降低了能耗，仅蒸汽一项每年就可节约７００万元，经济效益显著。实践证明活化ＭＤＥＡ法是合成氨工业中极具竞争力的高效、节能脱ＣＯ２方法。
The technical basis to transform CO2 removal plant of Liuzhou fertilizer factory from Benfield method into active MDEA method was illustrated. It raised the purity of the purified gas (H2, N2) and the reclaimed gas (CO2), and reduced energy consumption after the transformation was done. When using the active MDEA process, the cost of saved steam will be RMB$ 7 millions every year. The economic effectiveness is remarkable. Facts have proved that active MDEA method is a CO2 removal method of competitive efficiency and energy consumption in synthetic ammonia industry.
