Description

用于从含氮的天然气中制备低氮合成气的方法和装置
本发明涉及一种用于从含氮和二氧化碳的天然气中制备低氮合成气的方法,其中在第一变温吸附装置中从该含氮和二氧化碳的天然气中分离出水和二氧化碳,随后在低温气体分离器中分离出氮,从而使得产生低氮,无水和无二氧化碳的天然气,然后将该低氮,无水和无二氧化碳的天然气送入热化学转化,以便获取包括氢、一氧化碳、水和二氧化碳的合成粗气,至少通过在第二变温吸附装置中分离出水和二氧化碳从该包含氢、一氧化碳、水和二氧化碳的合成粗气中获得低氮合成气。
此外,本发明涉及一种用于执行所述方法的装置。
在这里所使用的语言中,如果一种成分在气体混合物中的所占部分不超过0.1ppmv,则认为该气体混合物不含该成分。相反,如果一种成分的所占部分大于0.5mol%,则称该气体混合物包含该成分。如果一种成分的所占部分介于0.5mol%至1ppmv之间,则认为气体混合物缺乏该成分。
被称为合成气的是至少包含氢和一氧化碳并且能够用于合成不同的产物的气体混合物。这些气体混合物主要由天然气制备,该天然气在其中通过自热重整(ATR)、部分氧化(POX)、蒸汽重整(SMR)或通过多年来在现有技术中已知的方法中的两者或多者的组合以热化学的方式进行转化。通常具有介于1mol%至10mol%之间的氮含量的含二氧化碳的天然气例如通过汞分离、脱硫、加热和压缩被处理成天然气进料,该天然气进料随后通过送入水和/或二氧化碳被转化为合成粗气,该合成粗气除了一氧化碳和氢之外还包含更大量的二氧化碳和水,以及其他在合成气中不需要的物质。为了获得低氮合成气,可在热化学转化的下游从制备好的合成粗气中去除氮,或者可在上游就已经从进料的天然气中去除氮。
如果氮分离在热化学转化的下游,则经脱硫和清除了汞的天然气以其全部氮负荷转化为含氮的合成粗气,首先例如在胺类洗涤器中从该合成粗气中分离出大部分二氧化碳,然后在变温吸附装置(以下简称为TWA)中去除水和剩余的二氧化碳残留物。这样所获得的基本由氢、一氧化碳和氮组成的气体混合物随后借助低温气体分离器分离成粗氢、一氧化碳和包含可燃物质的氮馏分。在粗氢被用作TWA中的再生气体之后,在变压吸附装置(简称为DWA)中将其净化成纯氢,该纯氢中的至少一部分与来自低温气体分离器的一氧化碳混合成低氮合成气。
在低温气体分离器中,一氧化碳和氮在塔中以整流的方式分离,由于这两种物质的沸腾温度非常相似,因此分离只有在具有高回流比和/或许多分离级的塔中才能实现。需要另一台压缩机,以便回收在DWA中净化粗氢时产生的含氢的残余气体,并将其用于热化学转化以实现足够高的产量,或将其作为燃料燃烧。由此产生的高额的装置费用和能源费用明显不利于该方法变体的经济性。
由于氮和甲烷的沸腾温度之差明显大于氮和一氧化碳的沸腾温度之差,因此相对容易的是,在低温气体分离器中以整流的方式将氮从含氮的天然气中分离出。特别地,使用的分离塔可在没有回流的情况下以节能的方式运行。因此,一种替代性的方法变体设置为,并非从合成粗气中才将氮分离出,而是从进料的天然气中就已经在低温方法中将氮分离出,并且通过热化学转化从这样获得的低氮天然气进料中制备同样低氮的合成粗气。将合成粗气处理成低氮合成气时,尽管在该方法变体中需要用于二氧化碳去除的装置和用于水和二氧化碳分离的TWA,但可省去复杂的低温合成气分离器、用于清洁粗氢的DWA以及用于含氢的DWA残余气体的再循环压缩机。但是缺点在于,必须在低温天然气分离器的上游布置至少一个附加的TWA以及在某些情况下布置用于二氧化碳去除的装置,这些装置防止水和二氧化碳与天然气一起进入低温天然气分离器,在此处它们可能发生冻结并导致堵塞。如果借助基于含水的洗涤剂的方法(如胺类洗涤器)去除二氧化碳,特别地会出现水饱和,从而使得即使进料的天然气是无水的,也需要用于水分离的TWA。
用于从气流中去除水和二氧化碳的变温吸附装置多年来同样为技术人员所熟知。要处理的气流在第一温度下被送入TWA,在此处,该气流流动穿过几个吸附器中的一个吸附器,这些吸附器各自填充有吸附材料,该吸附材料吸附和保留在气流中包含的水和二氧化碳,同时能够使其他物质如甲烷、氢或一氧化碳基本不受阻碍地通过。因此,气流以明显低于1ppmv的水和二氧化碳含量离开吸附器。
由于吸附材料吸收水和二氧化碳的能力是有限的,因此流向吸附器的气流必须在一定时间后中断,否则流出的气流的水或二氧化碳含量会超过极限值。在要处理的气流被转移到TWA的仍具有吸收力的吸附材料的吸附器的同时,对装载有水和二氧化碳的吸附器进行再生处理。为此,用再生气体冲洗该吸附器,该再生气体具有第二温度,该第二温度高于要处理的气流被送入该吸附器时的第一温度。吸附材料的吸附力随着温度的升高而降低,从而使得分离出的物质解吸附并且随着再生气体从吸附器中去除。如果没有上述粗氢,则通常使用氮作为再生气体,氮不被吸附材料吸附,或者吸附效果很差。因为除了水和二氧化碳之外,也从天然气和合成粗气中少量地分离出对环境有害的物质如甲烷和一氧化碳,并且在吸附器再生时将对环境有害的物质转移到再生气体中,所以不能将装载有有害物质的氮未经处理地释放到大气中。因此,为了遵守现有的排放极限值,氮以催化的方式进行后燃烧或借助火炬或方法炉中的辅助燃烧进行处置。
由于第一TWA和第二TWA均必须接受再生处理,因此在按照通用方法制备合成气时对再生气体的需求特别大。根据现有技术,导入低压氮作为再生气体,该低压氮的提供和处理构成重要的成本因素,对合成气制备的经济性起到明显的负作用。
本发明的目的在于,提出一种通用类型的方法以及一种用于执行该方法的装置,它们使得克服现有技术的所描述的缺点成为可能。
根据本发明,该目的在方法方面由此来实现,即在低氮,无水和无二氧化碳的天然气进行热化学转化之前,将其至少一部分用作第一变温吸附装置和/或第二变温吸附装置再生时的再生气体。
低氮,无水和无二氧化碳的天然气适合作为再生气体,因为该低氮,无水和无二氧化碳的天然气基本由甲烷组成,甲烷在用于水和/或二氧化碳分离的TWA中特别是在吸附器再生期间的温度下不被吸附或者只被极少量地吸附。
已知的是,能够用于水和二氧化碳分离的吸附材料可在升高的温度下特别地催化分解不饱和碳氢化合物,这导致不需要的碳沉积。尽管低氮,无水和无二氧化碳的天然气实际上不包含不饱和碳氢化合物,并且分解饱和碳氢化合物的风险也相当低,但本发明提出,根据本发明的TWA再生的温度限制在介于170℃和230℃之间,优选介于170℃和200℃之间。
如果从提供用于合成气制备的含氮和二氧化碳的天然气的总量中制备低氮,无水和无二氧化碳的天然气,则低氮,无水和无二氧化碳的天然气的量通常足以满足第一TWA和第二TWA的再生气体需求。于是就不需要输送另一种再生气体,例如氮。过多制备的,不需要用于TWA再生的低氮,无水和无二氧化碳的天然气可直接被送入热化学转化。但也可行的是,从含氮的天然气中只制备实际作为再生气体需要的这么多的低氮,无水和无二氧化碳的天然气。优选地,在可能必要地从含氮和二氧化碳的天然气中分离出汞和/或硫成分之后,将该含氮和二氧化碳的天然气的不提供用于水和二氧化碳分离的部分直接送入热化学转化。
吸附器再生时,在TWA中用作再生气体的低氮,无水和无二氧化碳的天然气装载上被解吸附的物质,其中主要为水和二氧化碳。适宜地,将装载有被解吸附的物质的再生气体在不改变其化学组分的情况下与吸附器再生时被解吸附的物质一起送入热化学转化。为此,要么吸附器再生这样缓慢地执行,使得只少量的水和二氧化碳经由再生气体路径进入热化学转化器,在此处,水和二氧化碳对合成气组分仅有可忽略不计的影响。由于热化学转化时需要水和二氧化碳作为反应物或温度调节剂,并且无论如何都要将水和二氧化碳作为进料物质送入热化学转化,因此,一种替代性的方法变体设置了这样的控制装置,该控制装置确保总是有方法所需的水和二氧化碳量进入转化器,不取决于再生气体的装载量。
如果低氮,无水和无二氧化碳的天然气既要用于第一变温吸附装置再生又要用于第二变温吸附装置再生,则将低氮,无水和无二氧化碳的天然气的确定为再生气体的部分优选地分成第一分流和第二分流,其中第一分流作为再生气体只被送入第一TWA,并且第二分流作为再生气体只被送入第二TWA。为了最小化流量损失,合理的是,只向每个TWA输送其所需的最低量的再生气体。
但也可行的是,输送确定为再生气体的低氮,无水和无二氧化碳的天然气的总量,以用于这两个TWA中的一个TWA的再生,其中,在这两个TWA中的一个TWA中,该低氮,无水和无二氧化碳的天然气预装载上被解吸附的物质,随后在另一个TWA中用于吸附器再生。
由于经济和技术原因,只在要处理的气体混合物的二氧化碳含量不超过通常为1mol%的最大值时,借助TWA进行二氧化碳分离才是有意义的。如果含氮和二氧化碳的天然气包含比可在TWA中合理分离出的量更多的二氧化碳,根据本发明的方法的一个实施方案设置为,在TWA的上游将含氮和二氧化碳的天然气的二氧化碳含量降低到低于所述最大值。优选地,为此使含氮和二氧化碳的天然气经受酸性气体洗涤器,例如胺类洗涤器。这里分离出的二氧化碳可释放到大气中,也可被送入物质回收利用装置。优选地,分离出的二氧化碳在下游被用于热化学转化。
根据本发明的方法基本与热化学转化的类型无关。因此,低氮,无水和无二氧化碳的天然气例如可通过自热重整、部分氧化、蒸汽重整或这些方法中的至少两者的组合来转化为合成粗气。
此外,本发明涉及一种用于从含氮和二氧化碳的天然气中制备低氮合成气的装置,该装置具有:第一变温吸附装置,用于从该含氮和二氧化碳的天然气中分离出水和二氧化碳,以及用于获取含氮,无水和无二氧化碳的天然气;低温气体分离器,用该低温气体分离器能够通过分离出氮从含氮,无水和二氧化碳的天然气中获得低氮,水和二氧化碳的天然气;热化学转化器,该热化学转化器用于将低氮,无水和无二氧化碳的天然气转化为包括氢、一氧化碳、水和二氧化碳的合成粗气;以及第二变温吸附装置,用该第二变温吸附装置能够将水和二氧化碳从合成粗气中分离出,以便获得低氮合成气。
根据本发明,所提出的目的在设备方面由此来实现,即低温气体分离器经由第一变温吸附装置和第二变温吸附装置如此与热化学转化器连接,使得在低氮,无水和无二氧化碳的天然气在热转化器中进行转化之前,能够将其至少一部分用作第一变温吸附装置和/或第二变温吸附装置再生时的再生气体。
优选地,第一TWA和第二TWA与热化学转化器的连接被这样实施,使得能够将低氮,无水和无二氧化碳的天然气的用作再生气体的部分与吸附器再生时被解吸附的物质一起送入热化学转化器。特别地,该连接不包括用于从使用的再生气体中分离出水和/或二氧化碳的装置。
在根据本发明的装置的一个优选变体中,低温气体分离器这样与第一TWA和第二TWA连接,使得确定为再生气体的低氮,无水和无二氧化碳的天然气的第一部分只能在第一TWA中用作再生气体,并且第二部分只能在第二TWA中用作再生气体。合理的是,该连接包括分配器,经由该分配器能够对应于两个TWA的当前再生气体需求调整低氮,无水和无二氧化碳的天然气的质量流。
这样的连接也是可行的,在该连接中低温气体分离器和两个TWA串联布置,从而使得可将确定为再生气体的低氮,无水和无二氧化碳的天然气的总量首先送入一个TWA,随后再送入另一个。在这种情况下,适宜的是,仅流动方向上的最后一个TWA直接与热化学转化器连接,从而使得能够将在两个TWA中用作再生气体并且在吸附器再生时装载上被解吸附的物质的低氮,无水和二氧化碳的天然气引入热化学转化器。
如果含氮和二氧化碳的天然气包含比可在TWA中合理分离出的量更多的二氧化碳,根据本发明的装置被实施具有布置在第一TWA的上游的装置,用于从天然气中分离出二氧化碳的主要部分。优选地,该装置为酸性气体洗涤器,例如胺类洗涤器。适宜的是,该用于分离出二氧化碳的装置这样与热化学转化器连接,使得可将从天然气中分离出的二氧化碳作为进料物质送入热化学转化器。
根据本发明的装置的一个变体设置了这样一种旁通管路,经由该旁通管路能够将含氮和二氧化碳的天然气的不需要用于为两个TWA制备再生气体的部分在可能的分离汞和/或硫成分之后绕过第一TWA、低温气体分离器以及必要时用于分离二氧化碳的装置直接送入热化学转化器。
进一步地,本发明提出,热化学转化器被实施为自热重整器或部分氧化反应器或蒸汽重整器,或者被实施为这些装置中的至少两者的组合。
下面借助在图1中示意性地示出的实施例更详细地解释本发明。
图1显示了本发明的一个变体,在该变体中从含氮和二氧化碳的天然气中制备低氮氧化气。
经由管路1将含氮和二氧化碳的天然气送入净化装置R,在此处,在第一净化步骤中分离出汞等物质。随后将如此处理过的天然气2送入酸性气体洗涤器W1,以便去除包含的二氧化碳3的主要部分,该酸性气体洗涤器例如为胺类洗涤器。天然气以降低的二氧化碳含量经由管路4流入第一TWA T1,在此处分离出水以及剩余的二氧化碳,并且制备含氮,无水和无二氧化碳的天然气5,在低温气体分离器N中将该含氮,无水和无二氧化碳的天然气分离成低氮,无水和无二氧化碳的天然气6和富含氮的燃料气体馏分7。在压缩机P1中增加压力之后,将低氮,无水和无二氧化碳的天然气8分成第一分流9和第二分流10,其中第一分流9被用作第一TWA T1中的吸附器再生的再生气体,而第二部分10出于同样的目的被送入布置在更下游的用于气体干燥的第二TWA T2。引导回装载有被解吸附的水和二氧化碳的两股再生气体流11和12,并且经由管路13作为天然气进料送入热化学转化器K。在热化学转化器K中,将天然气进料13与蒸汽14以及二氧化碳15和适当时的氧气22一起转化为包括氢、一氧化碳、水和二氧化碳的合成粗气16,在冷却装置G中冷却之后,将该合成粗气经由管路17引导到另一个酸性气体洗涤器W2,以用于分离出二氧化碳18,该洗涤器同样可被实施为胺类洗涤器。在第二TWA T2中,为二氧化碳含量降低的合成粗气19清除掉水和二氧化碳残留物,其中获得基本由氢和一氧化碳组成的无氮的合成气20作为产物。从冷却的合成粗气17中分离出的二氧化碳18在加入从天然气2中分离出的二氧化碳3以及导入的二氧化碳21以用于增加一氧化碳的产量之后,经由第二压缩机P2和管路15作为进料被引导回热化学转化器K。
