在这些附图中，用于分离二氧化碳和氧气或一氧化碳的塔不包括底部再沸器，底部液体仅在设备的主交换器中蒸发，在该主交换器中来自蒸馏塔的顶部气体被再加热。
具体实施方式
图1中，包括二氧化碳和氧气或一氧化碳的湿气体1在压缩机3中被压缩。此压缩机3包括四个级3A、3B、3C、3D，每个级后面为冷却装置5A、5B、5C、5D。在冷却装置5D中冷却之后，气体1由冷却器5E冷却以便形成气体7，然后(将气体7)发送至净化单元9以便移除水分。所形成的干燥气体11在第一交换器43中冷却，在第一交换器43中干燥气体11冷却并且部分地冷凝。部分冷凝的气体被发送至相分离器13。来自相分离器13的液体被发送至阀21以便形成液体23，该液体23在蒸馏塔25的顶部进给至该蒸馏塔25。
富含氧气和/或一氧化碳的气体26从塔的顶部取出并且发送至冷却器5D的上游。可选地，它可返回至产生气体1的富氧燃烧单元。
富含二氧化碳的来自蒸馏塔25的底部液体27被发送至第一交换器43，在此处蒸发以便形成流31，该流31在阀32中降低压力之后返回蒸馏塔25的底部。
底部液体的剩余物/其余部分29并不在交换器中加热而是与循环流体51混合。所形成的混合物31分成三个部分。部分37通过阀41将压力降低至低压，在第一交换器43中蒸发并且然后在压缩机47中压缩。部分35通过阀39将压力降低至中压，在第一交换器43中蒸发并且然后由压缩机45压缩。部分33在没有降低压力的情况下在第一交换器43中蒸发并且然后与所述两个经压缩的部分混合。由此形成的混合物49在压缩机51中压缩、冷凝并且然后分成两部分。部分56由泵53加压以便形成液体产品。剩余物55在第一交换器43中冷却，在阀57中降低压力并且与流29混合以便作为制冷循环返回至第一交换器43。
来自相分离器13的气体15在第一交换器43中再加热以便形成流17，该流17由再热器5F、5G再加热并且通过串联的两个涡轮19F、19G降低压力以便形成压力降低的流19。
在图2中，与图1不同的是，底部液体27的部分61通过完全穿过第一交换器43而蒸发和再加热以便作为流61被发送至压缩机47的下游，该流61被发送至压缩机47的下游。这个可选的形式特别有利，因为这避免了使在蒸馏塔的压力下蒸发的液体过冷(特别是如果流33被降低至零)；因此，这会减轻交换器的冷端的负担并且改善液化能。这会因为过冷仅在液体压力降低时才会被证实存在，因为此时转换成蒸气的部分减少，甚至于没有。
在图3中，与图2不同的是，蒸发的液体61的部分63没有在交换器43中冷却、而是在阀62中降低压力之后返回至蒸馏塔25的底部。此可选的形式特别有利于控制再沸气体的温度。
还可以将底部气体27分成至少两部分，一部分在交换器43中蒸发，然后返回至蒸馏塔25，另一部分(可选地剩余部分)在第二蒸馏塔中处理以便生产富含二氧化碳的产品。
图4示出这样的情况，其中该方法使得可以在塔25的分离的上游利用专门的塔125使混合物净化去除NO。该专门的塔125是用于去除NOx的塔。用于去除NOx的塔使得能够降低进入塔的气体的NO和/或NO2和/或N2O的含量。包括二氧化碳和氧气或一氧化碳的湿气体1在压缩机3中被压缩。此压缩机3包括四个级3A、3B、3C、3D，每个级后面为冷却装置5A、5B、5C、5D。在冷却装置5D中冷却之后，气体1由冷却器5E冷却以便形成气体7，然后(将气体7)发送至净化单元9以便移除水分。所形成的干燥气体11在第一交换器43中冷却并且然后在交换器43的中间位置取出以便发送至塔125的底部。塔125为没有底部再沸器或顶部冷凝器的简单的塔。其充当汽提塔以便使气体11净化去除NOx。富含NO的液体127在塔125的底部取出并且被发送至为气体1来源的锅炉或者被储存。经净化除去NOx的气体113从塔125的顶部离开，在交换器43中冷却并且部分地冷凝。将部分冷凝的气体发送至相分离器13。将来自相分离器13的液体发送至阀21以便形成液体23，该液体23在蒸馏塔25的顶部进给蒸馏塔25。
富含氧气和/或一氧化碳的气体26从塔的顶部取出并且发送至冷却器5D的上游。可选地，该气体26可返回至产生气体1的富氧燃烧单元。可通过渗透或其他手段分离此气体以便形成待重新加热的其他气体。
富含二氧化碳的来自蒸馏塔25的底部液体27被发送至第一交换器43，在第一交换器43中蒸发以便形成流31，该流31在阀32中降低压力后返回蒸馏塔25的底部。
底部液体的部分29与流体50混合并且然后分成三部分。部分37通过阀41将压力降低至低压，在第一交换器43中蒸发并且然后在压缩机47中压缩。部分35通过阀39将压力降低至中压，在第一交换器43中蒸发并且然后由压缩机45压缩。部分33在没有降低压力的情况下在第一交换器43中蒸发并且然后与所述两个经压缩的部分混合。由此形成的混合物49在压缩机51中压缩、冷凝并且然后分成两部分。部分56由泵53加压以便形成液体产品。剩余物55在第一交换器43中冷却并且分成两个部分。部分59在阀57中降低压力并且与流29混合以便作为制冷循环返回至第一交换器43。
另一部分155在阀157中降低压力并且然后以液态方式输送至用于移除NOx的塔125的顶部。
来自相分离器的气体15在第一交换器43中再加热以便形成流17，该流17由再热器5F、5G再加热并且通过串联的两个涡轮19F、19G降低压力以便形成压力降低的流19。
