Description

本発明は、例えばガス中の一酸化炭素（ＣＯ）を、水蒸気を用いて化学反応を行い、水素（Ｈ2）と二酸化炭素（ＣＯ2）とに改質する化学反応器に関する。 The present invention relates to a chemical reactor in which, for example, carbon monoxide (CO) in a gas is subjected to a chemical reaction using steam to be reformed into hydrogen (H 2 ) and carbon dioxide (CO 2 ).

例えばＣＯシフト反応器等の化学反応器は、例えば、石炭ガス化ガスの精製工程などでＣＯ2を除去する際に、必須となる。
すなわち、石炭ガス化ガス（生成ガス）中に存在する炭化水素化合物は、殆どが一酸化炭素（ＣＯ）であり、二酸化炭素（ＣＯ2）、炭化水素（ＣＨ4、ＣnＨm）は数パーセントに過ぎない。この結果、ＣＯ2を回収するためには、生成ガス中に存在するＣＯをＣＯ2に転換する必要があり、スチーム（Ｈ2Ｏ）を添加しつつ、シフト触媒により下記反応によってＣＯ2に転換することが提案されている（特許文献１）。
ＣＯ＋Ｈ2Ｏ⇔ ＣＯ2＋Ｈ2＋４０．９ｋＪ／ｍｏｌ For example, a chemical reactor such as a CO shift reactor becomes indispensable when removing CO 2 in, for example, a purification process of coal gasification gas.
That is, most of the hydrocarbon compounds present in the coal gasification gas (product gas) are carbon monoxide (CO), and carbon dioxide (CO 2 ) and hydrocarbons (CH 4 , CnHm) are only a few percent. Absent. As a result, in order to recover CO 2 , it is necessary to convert CO present in the product gas into CO 2 , and with the addition of steam (H 2 O), the shift catalyst converts it into CO 2 by the following reaction. It has been proposed (Patent Document 1).
CO + H 2 O⇔CO 2 + H 2 +40.9 kJ / mol

上記化学反応器に対しては、スチームを用いて改質反応を行うので、通常は、反応器自身や、プロセスの他反応器の発熱を回収して、反応器とは別の蒸発器を別途用意してスチームを発生させることが多い。このため、化学反応器以外に通常は蒸発器が必要となる。   Since the reforming reaction is performed on the chemical reactor using steam, usually, the heat generated by the reactor itself or other reactor in the process is recovered, and an evaporator separate from the reactor is separately provided. It is often prepared to generate steam. For this reason, an evaporator is usually required in addition to the chemical reactor.

本発明による実施例に係る化学反応器について、図面を参照して説明する。図１は、実施例１に係る化学反応器の概略図である。
図１に示すように、本実施例に係る化学反応器１０Ａは、反応器本体１０ａ内に設けられ、化学反応させる被処理ガス（例えばＣＯを含むガス）１１を供給するガス供給部１２と、化学反応後の反応生成ガス（例えばＨ2、ＣＯ2等）１３を排出するガス排出部１４と、前記ガス供給部１２に一端が接続されると共に、前記ガス排出部１４に他端が接続され、その内部に触媒（ＣＯ改質触媒）１５を充填してなる複数の触媒反応管１６と、触媒反応管１６の周囲に水（ボイラ水）１７を供給すると共に、発生するスチーム滞留部１８ａを有する水供給部１８と、を具備すると共に、前記水供給部１８内に供給した水１７が、化学反応の発熱により発生したスチーム１９をスチーム滞留部１８ａに溜め、この発生させたスチーム１９を、前記ガス供給部１２内に導入するものである。 A chemical reactor according to an embodiment of the present invention will be described with reference to the drawings. 1 is a schematic view of a chemical reactor according to Example 1. FIG.
As shown in FIG. 1, a chemical reactor 10A according to the present embodiment is provided in a reactor main body 10a, and supplies a gas to be treated (for example, a gas containing CO) 11 to be chemically reacted, One end is connected to the gas discharge section 14 for discharging a reaction product gas (for example, H 2 , CO 2, etc.) 13 after the chemical reaction, and the gas supply section 12, and the other end is connected to the gas discharge section 14. In addition, a plurality of catalyst reaction tubes 16 filled with a catalyst (CO reforming catalyst) 15 therein, water (boiler water) 17 is supplied around the catalyst reaction tube 16, and a generated steam retaining portion 18a is provided. And the water 17 supplied into the water supply unit 18 accumulates the steam 19 generated by the heat generated by the chemical reaction in the steam retention unit 18a, and the generated steam 19 The above It is intended to be introduced into the feed section 12.

なお、触媒反応管１６は、ガス供給部１２側とガス排出部１４側とに各々設けられた管板２５、２６に接続され、触媒反応管１６とガス供給部１２及びガス排出部１４とが連通されている。
また、被処理ガス１１は、ガス供給部１２内にガス導入管１２ａにより導入され、生成した反応生成ガス１３は、ガス排出部１４からガス排出管１４ａにより、後流側に排出される。 The catalyst reaction tube 16 is connected to tube plates 25 and 26 provided respectively on the gas supply unit 12 side and the gas discharge unit 14 side, and the catalyst reaction tube 16, the gas supply unit 12, and the gas discharge unit 14 are connected to each other. It is communicated.
Further, the gas 11 to be treated is introduced into the gas supply unit 12 through the gas introduction pipe 12a, and the generated reaction product gas 13 is discharged from the gas discharge unit 14 to the downstream side through the gas discharge pipe 14a.

これにより、水供給部１８に供給された水１７が化学反応により発生した熱により、スチームとなり、この発生したスチームを直接ガス供給部１２内に供給することができる。   Thereby, the water 17 supplied to the water supply unit 18 becomes steam by the heat generated by the chemical reaction, and the generated steam can be directly supplied into the gas supply unit 12.

スチーム１９を供給するには、ガス供給部１２側の管板２５に設けた減圧弁２０を介して行う。そして、この減圧弁２０の開度を調整して、直接スチームの供給量を調整することができ、この供給されたスチーム１９は被処理ガス（例えばＣＯを含むガス）１１と混合される。   The steam 19 is supplied through a pressure reducing valve 20 provided on the tube plate 25 on the gas supply unit 12 side. The opening amount of the pressure reducing valve 20 can be adjusted to directly adjust the supply amount of steam, and the supplied steam 19 is mixed with the gas to be treated (for example, gas containing CO) 11.

次いで、スチーム１９が混合された被処理ガス１１は、触媒反応管１６内に導入され、ここでＣＯ改質触媒の触媒反応によりＣＯシフト反応が進行し、改質ガスである反応生成ガス（Ｈ2、ＣＯ2等）１３が得られる。 Next, the gas to be treated 11 mixed with the steam 19 is introduced into the catalyst reaction tube 16 where the CO shift reaction proceeds by the catalytic reaction of the CO reforming catalyst, and the reaction product gas (H 2 , CO 2 etc.) 13 is obtained.

次に、本実施例の化学反応器１０Ａを用いて、化学反応を起動する方法について説明する。
１） 先ず、水供給部１８内に水１７を供給する前に、その内部を不活性雰囲気とするために、窒素ガスパージを行う。
２） その後、水１７を水供給部１８内に供給する。その際スチーム滞留部１８ａを残して所定量供給する。
３） 一方、ガス供給部１２においても、窒素ガスパージさせる。
４） 次に、ガス供給部１２内に、被処理ガス１１を供給すると共に、被処理ガス１１にスチームを一時的に別途供給する。
このスチームは化学反応を開始させるための一時的なものである。例えばガス導入管１２ａにスチーム供給管を接続してスチームを導入させるようにする。
５） 触媒反応管１６において、スチームが混合された被処理ガス１１が導入されると、触媒反応が進行して発熱する。この発熱によりその周囲に存在する水供給部１８内の水１７の温度が上昇し、スチーム１９が発生する。
６） 発生したスチーム１９は、減圧弁２０を介してガス供給部１２内に導入する。
７） 所定時間経過した後、前記一時的に供給したスチームの供給を停止する。
８） スチーム滞留部１８ａ内に溜められたスチーム１９は、減圧弁２０を介して被処理ガス１１に供給される。 Next, a method for starting a chemical reaction using the chemical reactor 10A of the present embodiment will be described.
1) First, before supplying the water 17 into the water supply unit 18, a nitrogen gas purge is performed to make the inside of the water an inert atmosphere.
2) Thereafter, water 17 is supplied into the water supply unit 18. At that time, a predetermined amount is supplied leaving the steam retaining portion 18a.
3) On the other hand, the gas supply unit 12 is also purged with nitrogen gas.
4) Next, the gas 11 to be processed is supplied into the gas supply unit 12 and steam is temporarily supplied to the gas 11 to be processed.
This steam is temporary to initiate the chemical reaction. For example, a steam supply pipe is connected to the gas introduction pipe 12a to introduce steam.
5) In the catalyst reaction tube 16, when the gas to be treated 11 mixed with steam is introduced, the catalytic reaction proceeds to generate heat. Due to this heat generation, the temperature of the water 17 in the water supply unit 18 existing around the temperature rises and steam 19 is generated.
6) The generated steam 19 is introduced into the gas supply unit 12 through the pressure reducing valve 20.
7) After a predetermined time has elapsed, the supply of the temporarily supplied steam is stopped.
8) The steam 19 stored in the steam retention part 18 a is supplied to the gas 11 to be processed through the pressure reducing valve 20.

この際、スチーム１９の圧力は、４０ｋｇ／ｃｍ2Ｇであり、供給する被処理ガス１１の圧力は３５ｋｇ／ｃｍ2Ｇとしているので、所定の圧力差（本実施例では５ｋｇ／ｃｍ2Ｇ）をもっており、ガス供給部１２に供給することができる。
本実施例では、一時的に供給するスチームはガス導入管１２ａに導入してよく、またはガス供給部１２内に直接導入するようにしてもよい。 At this time, the pressure of the steam 19 is 40 kg / cm 2 G, and the pressure of the gas to be treated 11 to be supplied is 35 kg / cm 2 G. Therefore, there is a predetermined pressure difference (5 kg / cm 2 G in this embodiment). , Can be supplied to the gas supply unit 12.
In the present embodiment, the temporarily supplied steam may be introduced into the gas introduction pipe 12 a or may be introduced directly into the gas supply unit 12.

このようなシェル＆チューブ形式の反応器は、ＣＯシフト反応器として洋上プラントに設置される場合、従来のような蒸発器が不要となる。
洋上プラントに適用するＣＯシフト反応器の一例で、シェル（反応器本体１０ａ）の長さが１７ｍであり、直径が３．８ｍである場合、その内部に配置されるチューブ（触媒反応管１６）は、長さが５７ｍｍであり、直径が７６ｍｍであり、これが約１，４００本配置されている。
このような大きさのＣＯシフト反応器に設置する従来の蒸発器の大きさは、例えば
直径が例えば１ｍで長さが例えば５ｍの横置きのタンクが必要であるので、この蒸発器が不要となるのは、洋上プラントのようなスペースが限定されている場合には、その寄与率は大きいものとなる。 Such a shell-and-tube type reactor does not require a conventional evaporator when installed in an offshore plant as a CO shift reactor.
In an example of a CO shift reactor applied to an offshore plant, when the length of the shell (reactor body 10a) is 17 m and the diameter is 3.8 m, a tube (catalyst reaction tube 16) disposed inside the shell Has a length of 57 mm and a diameter of 76 mm, and about 1,400 of them are arranged.
The size of a conventional evaporator installed in a CO shift reactor having such a size is, for example, that a horizontal tank having a diameter of, for example, 1 m and a length of, for example, 5 m is required. The reason for this is that the contribution rate is large when space such as an offshore plant is limited.

本実施例によれば、スチーム１９を反応器本体１０ａ内で直接発生させることができるので、従来用いられていたスチームを発生させるための蒸発器が不要となり、コンパクト性を確保することができる。   According to the present embodiment, since the steam 19 can be directly generated in the reactor main body 10a, a conventionally used evaporator for generating steam is unnecessary, and compactness can be ensured.

また、スチーム発生量に応じてスチーム反応量が変化し、スチーム１９の反応量をある程度、化学反応器１０Ａ自身で制御することが可能となる。   Further, the amount of steam reaction changes according to the amount of steam generated, and the reaction amount of the steam 19 can be controlled to some extent by the chemical reactor 10A itself.

この結果、本実施例によれば、蒸発器等の機器を不要化し、コンパクトな反応器を構成することが可能となる。また、反応量に応じセルフ制御でスチーム供給量を調整することが可能となる。   As a result, according to the present embodiment, it is possible to eliminate the need for equipment such as an evaporator and to configure a compact reactor. In addition, the steam supply amount can be adjusted by self-control according to the reaction amount.

よって、本発明の化学反応器は、例えば洋上プラント（例えば、浮体式海洋石油・ガス生産貯蔵積出施設（ＦＰＳＯ：Ｆｌｏａｔｉｎｇ Ｐｒｏｄｕｃｔｉｏｎ， Ｓｔｏｒａｇｅ ａｎｄ Ｏｆｆｌｏａｄｉｎｇ ｓｙｓｔｅｍ）等におけるＣＯシフト反応器に適用することで、その設置スペースのコンパクト化が図ることができる。   Therefore, the chemical reactor of the present invention is applied to, for example, a CO shift reactor in an offshore plant (for example, a floating marine oil and gas production storage and storage facility (FPSO: Floating Production, Storage and Offloading system), etc. The installation space can be made compact.
