Abstract
包括氢和/或至少一种烃和/或氮和/或一氧化碳的混合物的合成气体在洗涤塔(K01)、闪蒸塔(K02)、或蒸馏塔(K03)中被分离,这些塔中有结构填料。
Description
碳的混合物的分离方法及设备
本发明涉及一种用于分离一氧化碳和/或氢和/或至少一种烃和/或氮的混合物的方法和设备。
现有用于分离一氧化碳和氢的混合物的设备只包括板式塔。
尽管使用填料对其它类型的蒸馏(如常压蒸馏)来说已很平常,但空气的平衡系数实质上不同于一氧化碳、氢和/或甲烷混合物的平衡系数。
在具有甲烷洗涤(图1)的***中,在有压力存在的条件下被冷却到-180℃的合成气体在塔K01中被液态甲烷洗涤,一氧化碳被夹带到塔底,氢在塔顶产生。
被溶解的氢然后进入中压闪蒸塔K02中。CO/CH4两组分然后再在低压蒸馏塔K03中分离。气态CO在顶部产生,在底部产生的液态甲烷被泵送和再循环,用于在塔K01中进行洗涤。
在CO的循环中产生制冷能量。
在具有部分冷凝的***中(图2),在K11中通过从B01中产生的液态CO洗去了甲烷的合成气体被冷却到最低温度,下限是CO的凝固温度;在B02中冷凝的液体实质上是CO。
闪蒸塔K12和K13分别脱除被溶解于K11底部的液体(富甲烷)中和罐B02液体(富CO)中的氢。
从塔K12和K13中产生的液体然后被送入蒸馏塔K14中,在该蒸馏塔中CO/CH4产生分离。
通过在气轮机中氢的膨胀获得制冷能力。
在存在氮的特殊情况下,可在CO/CH4分离塔的下游增加一个N2/CO分离塔。
本发明的一个主题是提供一种分离包括氢和/或至少一种烃和/或氮和/或一氧化碳的气体混合物的设备,包括一个洗涤塔和/或一个闪蒸塔和/或一个蒸馏塔,其特征在于这些塔中至少有一个塔包含填料。
该填料最好是结构填料。
本发明的另一主题是提供一种在塔***中分离包括氢和/或至少一种烃和/或氮和/或一氧化碳的混合气体的方法,该塔系中至少有一个塔包括至少一个填料部分。
在其它实施方案提供的方法中,使用密度在400至1000m2/m3之间的结构填料。
填料因此可设置在洗涤塔、闪蒸塔和蒸馏塔内。
对于诸如用于一氧化碳和甲烷或一氧化碳和氮的蒸馏过程的在低压下操作的常规板式塔来说,通常压降较高。
使用填料能够使压差减小10倍,如果设定在设备出口处为低压,则可以在低压下进行蒸馏并且节省几个百分数的能源。
填料容许洗涤塔和蒸馏塔的高度和直径减小,通过用密度为870m2/m3的填料代替塔板,塔的高度能降低大约20%。
在闪蒸塔的情况下,塔底和塔顶之间的气体流速低且极易变化,因而塔板的穿孔弱并且各塔板之间相差很大,使它们很难制造。
另外,当蒸馏一种H2/CO/CH4的混合物时,在同一部分内部流速变化很大。用填料不会出现任何问题,但使塔板难以使用。
本发明的结构填料可以呈交叉波纹型。
