空分基本知识—空分生产的原理

信息来源:博大实地化学有限公司   点击次数:13846   发布时间:2012-12-17 10:22:27

    空分生产的原理就是利用低温精馏法将空气冷凝成液体(空气冷凝温度82K),按各组份蒸发温度的不同将空气分离。其具体原理为空气经过增压膨胀对外作功处于冷凝温度,当穿过比它温度低的氧、氮组成的液体层时,由于气、液之间温度差的存在,要进行热交换,温度低的液体吸收热量开始蒸发,其中氮组份首先蒸发,温度较高的气体冷凝,放出冷凝热,气体冷凝时,首先冷凝氧组份。这过程一直进行到气相和液相的温度相等为止,也即气、液处于平衡状态。这时,液相由于蒸发,使氮组份减少,同时由于气相冷凝的氧也进入液相,因此液相的氧浓度增加了,同样气相由于冷凝,使氧组份减少,同时由于液相的氮进入气相,因此气相的氮浓度增加了。多次的重复上述过程,气相的氮浓度就不断增加,液相的氧浓度也能不断的增加。这样经过多次的蒸发与冷凝就能完成整个精馏过程,从而将空气中的氧和氮分离开来。
