Description

生产二氧化碳的蒸馏系统
本发明一般涉及生产二氧化碳的蒸馏方法。
二氧化碳有许多用途，例如，二氧化碳用于碳酸盐饮料、冷却、冻结和包装海产品、肉类、家禽、烘干了的货物、水果和蔬菜，用于延长奶制品的贮藏寿命。在工业废物和工艺水处理中作为硫酸的替代物以控制pH含量它是一种重要的环境组分。其它用途包括饮用水的处理。环境友好的农药和温室中的大气添加剂以改良蔬菜的生长。
通常通过纯化废物来生产二氧化碳，这些废物流是有机或无机化学加工中的副产物。包含二氧化碳的废物流经冷凝，然后在蒸馏塔中处理来生产产品级的二氧化碳。
随着二氧化碳需求的不断增长，使用了更多勉强合格的二氧化碳源作粗二氧化碳加入纯化系统。这些勉强合格的进料可包含相当数量的轻质污染物。因此，在蒸馏成产品之前需要相当多的能量来进行所要求的液化。
因此，本发明的目的是提供一个以比常规处理二氧化碳系统可能的能效更高的方式来有效地处理含轻质污染物的粗二氧化碳进料的系统。
本领域的技术人员当阅读本公开后上述和其它目的将会很明了，通过本发明可达到上述和其它的目的，本发明的一个方面是：
生产二氧化碳的方法，包括：
A)将含二氧化碳和轻质污染物的进料通入塔中；
B)在塔内将进料分离成轻质的塔顶馏出物和二氧化碳产品；
C)通过与多组分热交换流体的间接热交换部分冷凝轻质的塔顶馏出物来产生回流液和保留污染物的蒸气；
D)使回流液往下通过塔；和
E)从塔的较低部位回收二氧化碳产品。
本发明的另一个方面是：
生产二氧化碳的方法，包括：
A)提供含二氧化碳和轻质污染物的进料；
B)将进料冷却以生成冷却的进料；
C)通过与多组分热交换流体的间接热交换至少部分冷凝冷却的进料，和将获得的进料通入塔中；
D)在塔内将进料分离成轻质的塔顶馏出物和二氧化碳产品；
E)从塔的较低部位回收二氧化碳产品。
此处所用的“塔”一词意指蒸馏或分馏塔或段，即接触塔或段，其中液体相和蒸气相逆流接触使流体混合物实现分离，例如通过在一系列安装在塔内的竖直空间的盘或板和/或在如规整填料或无规填料的填料单元中蒸气和液体相的接触，有关蒸馏塔的进一步讨论，见由R.H.Perry和C.H.Chilton编辑，纽约McGraw-Hill图书公司出版的《化学工程师手册》第五版，第13章“连续蒸馏的方法”。
蒸气和液体接触分离过程取决于组分蒸气压的差异。高蒸气压(或更易挥发的组分或低沸点)组分将倾向浓缩在蒸气相中，而低蒸气压(或低挥发性的或高沸点的)组分将倾向于浓缩在液体相中。部分冷凝是依靠冷却的蒸气混合物被用来在蒸气相中浓集挥发性组分和从而减少在液体相中的挥发性组分的分离方法。精馏、或连续蒸馏是如通过蒸气相和液体相逆流处理得到的逐级部分蒸发和冷凝相结合的分离方法。
通常蒸气相和液体相的逆流接触是绝热的并能包括相之间的积分(多级的)或微分(连续的)接触。利用精馏原理分离混合物的分离方法装置往往可互换地被叫作精馏塔、蒸馏塔或分馏塔。
此处所用的“较上部位”和“较低部位”术语分别意指塔中点以上和以下的塔的区段。
此处所用的“间接热交换”一词意指使两种流体产生热交换而无任何物理接触或流体与其它流体的相互混合。
此处所用的“冷凝器”一词意指一种间接热交换器，在其中含二氧化碳和轻质污染物的进料至少部分地被冷凝。
此处所用的“轻质污染物”一词意指一种或多种蒸气压高于二氧化碳的物质。轻质污染物的实例包括氮、氧、氩、氢和一氧化碳。
此处所用的“多组分热交换流体”一词意指一种具有两个或多个组分的流体，它具有不同的饱和曲线(沸点)。
多组分热交换流体是一种至少有两个组分的传热流体。经在温度范围部分冷凝的物流用某些多组分热交换流体能更有效地被冷凝，所设计的多组分热交换流体通过正确的选择组分、组合和操作压力使其严格地遵循冷凝传热曲线(Q对T曲线)。合适的多组分热交换流体由于通过部分冷凝热交换器降低了冷却的冷凝物流和蒸发的多组分热交换流体之间的温差而使工艺损失的功为最小。
此处所用的“低温冷却”一词意指使液体冷却到比当时压力下液体的饱和温度更低的温度。
此处所用的“涡轮膨胀”和“涡轮膨胀器”术语分别意指用于使高压气体流过涡轮机来降低气体的压力和温度，从而产生致冷的方法和装置。
图1是本发明一个优选实施方案的流程示意图；
图2是本发明另一优选实施方案的流程示意图；
图中共同单元的编号是相同的。
本发明一般包括在热交换环路中再循环的多组分热交换流体的使用，以部分地液化从蒸馏塔得到的塔顶馏出物或以液化至少一些进料，优选全部进料到塔中以使二氧化碳从轻质污染物中分离。多组分热交换流体能以较小的能量进行液化，其能量要低于用涡轮膨胀产生致冷，或用普通纯组分致冷剂吸收冷凝热所需的能量。
本发明将参照附图详细地叙述。现参见图1，将含二氧化碳、轻质污染物和水蒸气的进料物流50一般在常压下送入压缩机1中，在压缩机中被压缩到通常为60psia到90psia之间的压力。进料物流50一般从有机或无机化学生产系统的废液中获得。例如从生产乙醇和/或其它醇类的废液中。在进料中二氧化碳的浓度通常为25％到98％摩尔(干基)范围之内。本发明对于处理其中轻质物至少为15％摩尔(干基)的进料特别有效。
压缩后的进料51通过水或空气驱动的冷却器2而冷却，冷凝的水分在相分离器3中被分离。然后进料再通过压缩机4压缩到通常在280psia到325psia范围之内的压力。进一步压缩后的进料52通入冷却器5和6再冷却。从相分离器7中取出冷凝的水分，进料通入吸附床8中进一步干燥。
然后将冷却的、干燥进料物流53通入塔再沸器9冷却到接近它的露点并用导管送到冷凝器10中，在冷凝器中进料由于与再循环的纯组分热交换流体间接热交换至少部分地被冷凝，优选地是基本上整个地被冷凝。优选的纯组分热交换流体是氨。其它可用于本发明实施的纯组分热交换流体包括丙烷和卤代烃致冷剂。得到的冷凝后进料54通过阀11被闪蒸并如图1中所说明的，优选地在塔12顶部通入塔12中。
现再参见图1，通过压缩机15将气态的热交换流体55压缩到适中的压力，然后通入直接接触的后冷却器16中。从后冷却器16取出气态的中等压力热交换流体为物流56并在压缩机17中压缩成高压物流，然后该高压流体通过在热交换器18中与水或空气等的间接热交换基本上全部被冷凝。然后经阀门19并通入后冷却器16作冷却介质。从后冷却器16取出中等压力的冷却的液态热交换流体为物流57。如果有要求，如图1中所说明的，物流57的一部分58通入冷却器6以冷却进料，而后返回到后冷却器16中，物流57的其余部分经阀门20然后分成物流59和物流60。物流59用导管提供给冷凝器10，在其中经与上述的冷凝进料间接热交换而被汽化，得到的汽化热交换流体从冷凝器10中取出为物流61。物流60通入低温冷却器13中，在其中经与低温冷却产物间接热交换而被汽化。将得到的汽化物层62与物流61混合形成气态物流55并重复这闭合回路致冷循环。
塔12通常在250psig到320psig范围的压力下操作。在塔12中，进料经蒸馏被分离成轻质塔顶馏出物和二氧化碳产品。进料液体相对于向上流动的蒸气往下流过塔12和从往下流液体中汽提出经受污染物进入向上流蒸气中，以形成在塔12顶部的轻质塔顶流出物和在塔底部的二氧化碳产品。
通常，浓度为至少99.9％摩尔的二氧化碳产品液体以物流63从塔12的底部取出。部分物流64通入再沸器9中经与冷却的进料间接热交换而汽化。所得汽化的部分物流65返回到塔12中作为向上流动的蒸气。物流63的其余部分物流66通入低温冷却器13中进行低温冷却，经阀门14并以物流67作为产品二氧化碳回收。
含有污染物量比进料中提高了的和也含一些二氧化碳的轻质塔顶馏出蒸气从塔12的顶部取出，通过热交换器71被部分地冷凝，然后通入相分离器31中。通过相分离器31未被冷凝的污染物蒸气为蒸气流69，并通过热交换器71被加温而后从系统中取出。从相分离器31中得到的回流液为物流70通入塔12的顶部并而后往下流过塔12。
热交换器71由循环的多组分热交换流体驱动，该流体优选是由用于驱动热交换器10的致冷剂，如氨和第二种低沸物如氮所组成，可以使用的其它较低沸点物质包括氩、甲烷、乙烷和牌号为R14、R23、R32和R125的致冷剂。多组分热交换流体72在压缩机73中被压缩，然后被冷却和通过热交换器74与如水或压缩空气的合适的冷却液间接热交换，而优选地部分或全部地被冷凝。所得流体75再进一步被冷凝和/或通过热交换器76被低温冷却，然后分成两部分。第一部分77通过阀门78降压，然后通过热交换器71以部分地冷凝轻质塔顶馏出蒸气。第二部分通过阀门80降压，然后通过热交换器76以冷凝和/或低温冷却多组分热交换流体75。再混合物流77和79以形成物流72并重复闭合回路致冷循环。
图2说明本发明的另一实施方案，该方案对于在高压下操作特别有效。图2说明的方案中与图1说明的共同的那些部分不再详细加以叙述。现参见图2，将从冷却器5来的冷却后进料通入相分离器7中，然后通过压缩机107将其进一步压缩到通常为600psig到1200psig范围的压力。通过进一步压缩后的进料物流通过冷却器108冷却后通入相分离器109中，从中将水分除去。从相分离器109出来的蒸气可以进行以单元110表示的许多其它预处理步骤，以便除去如含有两个或三个碳原子烃的高沸点或重质污染物和如硫化氢等硫化物。单元110可包括吸收、氧化和/或吸附步骤。其后进料通过吸附床111进一步脱水。如有要求，可将单元110和111直接放在相分离器7之后。
将净化的进料83通过塔再沸器112冷却到接近它的露点，然后通过冷凝器114将其至少部分地，优选基本上全部冷凝，得到的液化进料物流84经过阀门300通入塔12中，在其中物流84以与图1所叙的类似方法进行加工。在图2说明的实施方案中，塔12可以在500psig到1000psig范围的压力下操作。
图2说明的本发明优选实施方案实施中使用的多组分热交换流体优选地是二元混合物。可以在本发明的多组分热交换流体中使用的物质包括氨、二氧化碳、氮、氩、如甲烷、乙烷、丙烷和丁烷等饱和烃、和卤代烃。优选地，该多组分热交换流体包括氨。最为优选的多组分热交换流体是一种包括氨和氮、氨和乙烷，或氨和卤代烃的二元混合物。
将多组分气态热交换流体通过压缩机117压缩和通过热交换器118与如水或空气等合适的冷却剂间接热交换而被冷却。将得到的流体87通过压缩机119进一步压缩和通过冷却器120与如水或空气等合适的冷却剂间接热交换而至少部分地被冷凝。然后将得到的多组分热交换流体进一步通过再沸器112而冷凝和/或低温冷却，从而补充到塔12再煮沸。将从再沸器112中得到的热交换流体89通过冷凝器114的第一通道，从冷凝器该流体基本上全以液体而流出。而后多组分热交换流体90经阀门121而膨胀成低压和接着通过冷凝器的第二通道而汽化。因此，汽化的多组分热交换流体吸收所需的热能以冷却和至少部分地冷凝进料，冷却和冷凝在冷凝器114第一通道中的高压多组分热交换流体和也低温冷却产物二氧化碳。然后将得到的汽化的热交换流体86通过压缩机117的入口并重复闭合回路致冷循环。
含轻质污染物的塔顶馏出蒸气从塔12的顶部取出为物流91，通过冷凝器114加热后从系统中流出。由于塔12是在高压下操作，物流91的部分物流92可以通过涡轮膨胀器116被膨胀随着得到的膨胀物流93通过冷凝器114而产生致冷作用和从系统中流出，膨胀的轴功可以用于产生电或用于压缩。
通常二氧化碳浓度至少为99.9％摩尔的二氧化碳产品液体从塔12的底部以物流63回收。部分物流64通过再沸器112与冷却的进料和多组分热交换流体间接热交换而汽化，所得的汽化的部分物流65返回到塔12中作为向上流的蒸气。物流63的其余部分物流66通过冷凝器114被低温冷却，经阀门14后作产品二氧化碳物流67回收。
由于使用本发明，现能通过低温精馏从含相当量轻质污染物的进料高效能和有效地提供产品级二氧化碳。尽管参见一些优选的实施方案详细地叙述了本发明，但本领域的技术人员将认识到在权利要求书的精神和范围之内本发明已有其它实施方案。
