Description

本発明は熱交換器のアセンブリ、これを組み込んでいる深冷蒸留装置、およびこれを用いる深冷蒸留方法に関する。   The present invention relates to a heat exchanger assembly, a cryogenic distillation apparatus incorporating the same, and a cryogenic distillation method using the same.

空気を蒸留するために、空気を非常に低い温度まで冷却する。外部環境との熱交換を制限するために、空気のガスから生じる流体の種々な段階の分離／液化が起こる種々のカラムおよび熱交換器は、１つ以上の断熱材（パーライト、ロックウール、など）によって断熱され、この断熱材は機械的な理由から通常コールドボックスと呼ばれる大きな構造体内に収容される。   In order to distill the air, the air is cooled to a very low temperature. Various columns and heat exchangers in which various stages of separation / liquefaction of fluids originating from air gases occur to limit heat exchange with the external environment include one or more insulations (perlite, rock wool, etc. This insulation is housed in a large structure, usually called a cold box, for mechanical reasons.

これらのコールドボックスの寸法は、カラムの数、熱交換器の数、これらのサイズ、種々の配管および二次的な低温要素、ならびに全てのこれらの低温要素と断熱材を収容する外部構造体との断熱距離に依存する。   The dimensions of these cold boxes include the number of columns, the number of heat exchangers, their size, various piping and secondary cold elements, and the external structure that houses all these cold elements and insulation. Depends on the insulation distance.

多くの場合に、この空気分離装置にとって、品質および制御の理由のために、「貴重な」部品、すなわちカラムおよび全てのまたは実質的に全ての二次的な低温要素および低温配管、ならびに熱交換器を含むこれらの構造体を、専門の作業場で予め組み立てることが有利である。これらの「コールドボックスパッケージ」の実現可能性の限界は、製造場所と最終設置場所との間の輸送のための形態となる。   In many cases, for this air separation unit, for quality and control reasons, “precious” parts, ie columns and all or substantially all secondary cryogenic elements and piping, and heat exchange It is advantageous to pre-assemble these structures, including the vessel, in a specialized workshop.

他の任意の態様によれば、
−ガス混合物は空気または空気の１つのガスまたは主な成分として水素および／または一酸化炭素および／またはメタンおよび／または窒素を有するガス混合物である。 According to any other aspect,
The gas mixture is air or a gas mixture having hydrogen and / or carbon monoxide and / or methane and / or nitrogen as the main component.

−ガス混合物は空気であり、カラムのシステムはともに熱的に結合した少なくとも１つの中圧カラムおよび少なくとも１つの低圧カラムを含み、液体酸素を気化して少なくとも１つの第２の熱交換器本体で酸素ガスを生成し、任意に、いずれの第１の本体でも気化しない。   The gas mixture is air and the system of columns comprises at least one medium pressure column and at least one low pressure column thermally coupled together, and vaporizes liquid oxygen in at least one second heat exchanger body Oxygen gas is generated and optionally does not vaporize in any first body.

−液体酸素を少なくとも１つの第１の本体で冷却し、任意に、いずれの第２の本体でも気化しない。   -Cool liquid oxygen in at least one first body and optionally do not vaporize in any second body.

−第１および／または第２の本体または複数の本体における液体流動方向は実質的に垂直であるが、液体は代わりに水平に流れてもよい。   The liquid flow direction in the first and / or second body or bodies is substantially vertical, but the liquid may instead flow horizontally.

熱交換器は一般にカラム一式よりも大きい床面積を占める。「パッケージ」アプローチを妨げるこの面積を制限するための１つの解決策は、蒸留を妨害することなく収容することができる熱交換器、典型的にはガス熱交換器を、収容することができない熱交換器、典型的には液体または液体の気化を伴う熱交換器の上に設置することである。床領域は大きく削減される。   The heat exchanger generally occupies a larger floor area than the column set. One solution to limit this area that hinders the “package” approach is to provide heat that cannot accommodate a heat exchanger, typically a gas heat exchanger, that can accommodate without disturbing distillation. Installation on an exchanger, typically a heat exchanger with liquid or liquid vaporization. The floor area is greatly reduced.

カラムと熱交換器を含む単独のパッケージアプローチを実施することができない場合には、積層された熱交換器の独立のパッケージが有利だろう。   In cases where a single package approach involving columns and heat exchangers cannot be implemented, an independent package of stacked heat exchangers would be advantageous.

このアプローチはこのパッケージの概念が無くとも踏襲され、単純に空気またはＨ２／ＣＯのようなガスの深冷分離ユニットの床面積を減じる。 This approach is followed without the concept of this package and simply reduces the floor area of a cryogenic separation unit of gas such as air or H 2 / CO.

本発明を図１ないし図６を参照して詳細に記述する。   The present invention will be described in detail with reference to FIGS.

図１ないし図３は本発明によるアセンブリを種々の角度から示す。   1 to 3 show the assembly according to the invention from various angles.

図１ないし図３は本発明による熱交換器アセンブリを示し、前記熱交換器アセンブリは２つの系列の熱交換器１、２を含み、第１の系列１は地上少なくとも１０ｍまたは１５ｍに設置され、第２の系列２は第１の系列の下に設置される。   1 to 3 show a heat exchanger assembly according to the invention, said heat exchanger assembly comprising two series of heat exchangers 1, 2 and the first series 1 being installed at least 10 m or 15 m above the ground, The second series 2 is installed below the first series.

第１の系列の熱交換器１はステンレス鋼フレーム３上に設置され、その脚部はコールドボックスパッケージの底に載っており、第２の系列の熱交換器はフレームの内部すなわち第１の系列の下に設置され、一方でこれを支持している。それらが互いからより効果的に断熱されているならば、第１の系列の熱交換器から形成される熱交換器のブロックを第２の系列から形成されるブロックの上に設置してもよい。なぜならば第１の系列の熱交換器の最も冷たい部分が第２の系列の最も熱い部分と対向して設置され、稼動中において一方がおよそ室温であり、他方が極低温だからである。コールドボックスパッケージは断熱材Ｉで充填される。   The first series of heat exchangers 1 are installed on a stainless steel frame 3 with their legs resting on the bottom of the cold box package, and the second series of heat exchangers inside the frame, ie the first series. On the other hand, supporting this. If they are more effectively insulated from each other, the block of heat exchangers formed from the first series of heat exchangers may be placed on top of the blocks formed from the second series. . This is because the coldest part of the first series of heat exchangers is placed opposite the hottest part of the second series, and one is at about room temperature and the other is cryogenic during operation. The cold box package is filled with thermal insulation I.

２つの熱交換器本体５が整列した熱交換器本体からなる第１の系列１を構成する。２つの実質的に同一な本体５はプレート熱交換器タイプであり、第１の寸法すなわち長さおよび第２の寸法すなわち幅に沿って広がる実質的に似通った外形で、第３の寸法すなわち厚さに沿って互いから離間し互いに対して平行な列をなして配置された複数の金属プレートを含む。シール手段がプレートとともに扁平流路を制限して、４種類の流路を形成し、これらの流路は本体の全長に沿って広がってはいない。各々のタイプの流路について、各々の流路に割り当てられたシール手段はその２つの末端において１つの流体入口および１つの流体出口を開放している。各々の第１の本体５の高温端における第１の入口Ｅ１は冷却される中圧空気の配給ラインＤ ＡＩＲ ＭＰに接続され、各々の第１の本体の中間位置における第１の出口Ｓ１は冷却された中圧空気の収集ラインＣ ＡＩＲＭＰに接続されている。各々の第１の本体５の中間位置における第２の入口Ｅ２は加熱される廃窒素の配給ラインＤＮＲに接続され、各々の第１の本体５の高温端における第２の出口Ｓ２は加熱された廃窒素の収集ラインＣＮＲに接続されている。   A first series 1 comprising heat exchanger bodies in which two heat exchanger bodies 5 are arranged is configured. Two substantially identical bodies 5 are of the plate heat exchanger type, with a substantially similar profile extending along a first dimension or length and a second dimension or width, and a third dimension or thickness. A plurality of metal plates arranged in rows parallel to each other and spaced apart from each other along the length. The sealing means restricts the flat flow path together with the plate to form four kinds of flow paths, and these flow paths do not extend along the entire length of the main body. For each type of flow path, the sealing means assigned to each flow path opens one fluid inlet and one fluid outlet at its two ends. The first inlet E1 at the high temperature end of each first body 5 is connected to a distribution line D AIR MP for medium pressure air to be cooled, and the first outlet S1 at the intermediate position of each first body is cooled. Is connected to the collected medium pressure air collection line CAIRMP. A second inlet E2 at an intermediate position of each first body 5 is connected to a heated waste nitrogen distribution line DNR, and a second outlet S2 at the hot end of each first body 5 is heated. It is connected to a waste nitrogen collection line CNR.

この系列の熱交換器１の各々の本体５はサブクーラーの機能も果たすので、特に各々の本体５の最も冷たい部分すなわち各々の第１の本体５の低温端における第３の入口Ｅ３は冷却される液体酸素の配給ラインＤＯＬに接続され、第１の本体の第３の出口Ｓ３は冷却された液体酸素の収集ラインＣＯＬに接続され、各々の第１の本体５の低温端における第４の入口Ｅ４は冷却される窒素富化液体の供給ラインＤＬＬに接続され、第１の本体の第４の出口Ｓ４は冷却された窒素富化液体の収集ラインＣＬＬに接続されている。   Each body 5 of this series of heat exchangers 1 also serves as a subcooler, so that the coldest part of each body 5, ie the third inlet E3 at the cold end of each first body 5, is cooled. And a third outlet S3 of the first body is connected to a cooled liquid oxygen collection line COL and a fourth inlet at the cold end of each first body 5 is connected to the liquid oxygen distribution line DOL. E4 is connected to a supply line DLL of nitrogen-enriched liquid to be cooled, and the fourth outlet S4 of the first body is connected to a collection line CLL of cooled nitrogen-enriched liquid.

第１の系列の少なくとも１つの本体はサブクーラーの機能を果たし、それによってアセンブリをより小型にできることは容易に理解できる。事実、第１の系列の本体がこの機能を果たさない場合、サブクーラーは好ましくは第１と第２の系列の間に設置される少なくとも１つの独立した熱交換器からなるであろう。装置がサブクーラーを含まないことも可能である。   It can be readily appreciated that at least one body of the first series serves as a subcooler, thereby making the assembly more compact. In fact, if the body of the first series does not perform this function, the subcooler will preferably consist of at least one independent heat exchanger installed between the first and second series. It is also possible that the device does not include a subcooler.

第１の系列の本体は必ずしも同一である必要はなく、特に全てが同じ流体を受ける必要はないことも理解されるであろう。   It will also be appreciated that the first series of bodies need not be identical, and in particular not all need to receive the same fluid.

４つの第２の熱交換器本体７が配列した熱交換器本体の第２の系列を構成し、これらはフレーム３によってコールドボックスの底のわずか上に支持されている。４つの実質的に同一の本体７は各々プレート熱交換器タイプであり、第１の寸法すなわち長さおよび第２の寸法すなわち幅に沿って広がる実質的に似通った外形で、第３の寸法すなわち厚さに沿って互いから離間し互いに対して平行な列をなして配置された複数の金属プレートを含む。シール手段がプレートとともに扁平流路を制限して、本体の全長沿って広がる５種類の流路を形成する。各々のタイプの流路について、各々の流路に割り当てられたシール手段はその２つの末端において１つの流体入口および１つの流体出口を開放している。各々の第２の本体７の高温端における１つの第１の入口Ｅ１’は第１の高圧まで冷却される空気の配給ラインＤ１ ＡＩＲ ＨＰに接続され、各々の第２の本体７の低温端における第１の出口Ｓ１’は冷却された高圧空気の収集ラインＣ２ ＡＩＲ ＨＰに接続されている。各々の第２の本体７の高温端における第２の入口Ｅ２’は第２の高圧まで冷却される空気の配給ラインＤ２ ＡＩＲ ＨＰに接続され、各々の第２の本体の低温端における第２の出口Ｓ２’は冷却された高圧空気の収集ラインＣ１ ＡＩＲ ＨＰに接続されている。各々の第２の本体７の低温端の第３の入口Ｅ３’は加熱される廃窒素の配給ラインＤＮＲ’に接続され、各々の第２の本体７の高温端における第３の出口Ｓ３’は加熱された廃窒素の収集ラインＣＮＲ’に接続されている。   Four second heat exchanger bodies 7 constitute a second series of heat exchanger bodies arranged and supported by frame 3 just above the bottom of the cold box. The four substantially identical bodies 7 are each of the plate heat exchanger type, with a substantially similar profile extending along a first dimension or length and a second dimension or width, and a third dimension or It includes a plurality of metal plates arranged in rows that are spaced apart from and parallel to each other along the thickness. The sealing means restricts the flat flow path together with the plate to form five types of flow paths that extend along the entire length of the main body. For each type of flow path, the sealing means assigned to each flow path opens one fluid inlet and one fluid outlet at its two ends. One first inlet E1 ′ at the hot end of each second body 7 is connected to an air distribution line D1 AIR HP cooled to a first high pressure, and at the cold end of each second body 7. The first outlet S1 'is connected to a collection line C2 AIR HP for cooled high pressure air. A second inlet E2 ′ at the hot end of each second body 7 is connected to an air distribution line D2 AIR HP cooled to a second high pressure, and a second at the cold end of each second body. The outlet S2 ′ is connected to a collection line C1 AIR HP for cooled high pressure air. The third inlet E3 ′ at the cold end of each second body 7 is connected to the heated waste nitrogen distribution line DNR ′, and the third outlet S3 ′ at the hot end of each second body 7 is It is connected to a heated waste nitrogen collection line CNR ′.

第１の系列と異なり、第２の系列の本体７は窒素ガス配給ラインおよび液体酸素ラインに接続されている。各々の第２の本体７の低温端における第４の入口Ｅ４’は加熱される窒素の配給ラインＤＮに接続され、各々の第２の本体７の高温端における第４の出口Ｓ４’は加熱された廃窒素の収集ラインＣＮに接続されている。各々の第２の本体７の低温端の第５の入口Ｅ５’は気化される液体酸素の配給ラインＤＯＬに接続され、各々の第２の本体７の高温端における第５の出口Ｓ５’は気化された酸素の収集ラインＣＯＧに接続されている。   Unlike the first series, the second series main body 7 is connected to a nitrogen gas distribution line and a liquid oxygen line. The fourth inlet E4 ′ at the cold end of each second body 7 is connected to the heated nitrogen delivery line DN, and the fourth outlet S4 ′ at the hot end of each second body 7 is heated. It is connected to a waste nitrogen collection line CN. The fifth inlet E5 ′ at the cold end of each second body 7 is connected to the liquid oxygen delivery line DOL to be vaporized, and the fifth outlet S5 ′ at the hot end of each second body 7 is vaporized. Connected to the collected oxygen collection line COG.

第２の系列の本体は必ずしも同一である必要はなく、特に全てが同じ流体を受ける必要はないことも理解されるであろう。   It will also be appreciated that the second series of bodies need not be identical, and in particular not all need to receive the same fluid.

第１の系列の熱交換器本体と第２の系列の熱交換器本体との間の２つの主な違いを確認することができる。   Two main differences between the first series of heat exchanger bodies and the second series of heat exchanger bodies can be identified.

第一に、気化されるあらゆる液体は、第２の系列の本体の少なくとも１つ、好ましくは全てに送られる。したがって第１の系列の本体は、液体酸素を例えばいくつかの圧力まで気化させるための少なくとも１つのタイプの流路を含んでいるであろう。これらは液体窒素を気化させるための流路を含んでいるであろう。   First, any liquid to be vaporized is sent to at least one, preferably all, of the second series of bodies. Thus, the first family of bodies will include at least one type of flow path for vaporizing liquid oxygen, for example to several pressures. These will include a flow path for vaporizing liquid nitrogen.

第二に、与えられた閾値を上回る圧力にある冷却または加熱されるあらゆる流体は第２の系列に送られる。この第２の系列は明らかにより低い圧力にある流体を受けることもできるが、本体は高圧での使用を意図されている。閾値は３０ｂａｒ ａｂｓ、２０ｂａｒ ａｂｓもしくは１５ｂａｒ ａｂｓでもよい。   Second, any fluid to be cooled or heated that is at a pressure above a given threshold is sent to the second series. While this second series can also receive fluids that are clearly at lower pressures, the body is intended for use at higher pressures. The threshold may be 30 bar abs, 20 bar abs or 15 bar abs.

熱交換器１および２の系列について、熱交換器本体５、７ならびに配給および収集ラインはパーライトまたはロックウールＩで断熱されなければならない。各々の系列を熱交換器およびいくつかの配給および収集ラインのみを含む個々のコールドボックス４内に設置してもよいし、２つの系列を熱交換器本体およびそれらの収集および配給ラインを含む共通のコールドボックス内に設置してもよいし、両方の系列を空気分離カラムのシステムとともに共通のコールドボックス内に設置してもよい。   For the series of heat exchangers 1 and 2, the heat exchanger bodies 5, 7 and the distribution and collection lines must be insulated with perlite or rock wool I. Each series may be installed in an individual cold box 4 containing only heat exchangers and some distribution and collection lines, or two series in common including heat exchanger bodies and their collection and distribution lines May be installed in a cold box, or both systems may be installed in a common cold box with an air separation column system.

図４および５はアセンブリの下部をより詳細に示す。   4 and 5 show the lower part of the assembly in more detail.

ＥＰ Ａ １ ２３０ ５２２に記載されているように、低圧の酸素に対して中圧の窒素を気化させるために用いられるダブル空気分離カラムのリボイラ−コンデンサはカラムの外側に設置してもよい。この場合、リボイラ−コンデンサは、系列１の上または２つの系列の間の熱交換器の系列１、２として同じコールドボックス４内に設置してもよい。このように、同じ製造者によって供給される全ての要素（熱交換器、リボイラ−コンデンサ）は、現場に直接供給できる１つのパッケージ内に設置される。各々の要素（上部の熱交換器、下部の熱交換器、および任意にリボイラ）は、独立のコールドボックス内で断熱されてもよいし、これらの要素のいくつかは共通のコールドボックス内に設置されてもよいことが理解されるだろう。   As described in EP A 1 230 522, the reboiler condenser of a double air separation column used to vaporize medium pressure nitrogen against low pressure oxygen may be installed outside the column. In this case, the reboiler-condenser may be installed in the same cold box 4 as series 1 or 2 of heat exchangers above series 1 or between two series. In this way, all the elements supplied by the same manufacturer (heat exchanger, reboiler-condenser) are installed in one package that can be supplied directly to the site. Each element (upper heat exchanger, lower heat exchanger, and optionally reboiler) may be insulated in a separate cold box, or some of these elements may be installed in a common cold box It will be understood that this may be done.

One part OL is sent to the coldest part of the body of series 1 and subcooled before being sent to the storage S. Deliver the rest and form a flow OLP at least 20 bar abs or at least 30 bar abs. This stream OLP is vaporized in the body of the second series to produce a stream OG.
