　［有機物質製造方法］
　本発明の有機物質製造方法は、合成ガスを触媒反応装置に供給する合成ガス供給工程と、触媒反応装置において合成ガスから有機物質を合成する有機物質合成工程と、前記反応装置から排気ガスを排出する排気ガス排出工程と、前記排気ガスに混入している蒸気、液体及び泡沫のうち少なくとも１種を前記排気ガスから分離除去する混入物除去工程と、前記排気ガスの成分組成を測定する排気ガス測定工程とを含む。以下では、本発明の有機物質製造システム１０を用いる場合の本発明の有機物質製造方法の実施形態について詳細に説明する。 [Organic substance manufacturing method]
The method for producing an organic substance of the present invention includes a synthetic gas supply step of supplying a synthetic gas to a catalytic reaction device, an organic substance synthesis step of synthesizing an organic substance from the synthetic gas in the catalytic reaction device, and exhaust gas from the reaction device. Exhaust gas discharge step, a contaminant removal step of separating and removing at least one of steam, liquid, and foam mixed in the exhaust gas from the exhaust gas, and an exhaust gas for measuring the component composition of the exhaust gas. Includes measurement steps. Hereinafter, embodiments of the organic substance manufacturing method of the present invention when the organic substance manufacturing system 10 of the present invention is used will be described in detail.
　合成ガス供給工程では、合成ガスＡを、合成ガス源（図示せず）から合成ガス供給ライン２を通じて、触媒反応装置１の合成ガス入口に供給する。合成ガスＡは、例えば、一酸化炭素、水素、二酸化炭素及び窒素を含む混合ガスである。合成ガスは、廃棄物焼却炉から発生する原料ガス、製鉄所から発生する原料ガス等の原料ガスを処理して、製造したものが好ましい。合成ガスＡの触媒反応装置１への供給量は、合成ガス供給ライン２に設置した測定装置から得られる合成ガスＡの成分組成、及び排気ガス測定ライン７に設置した測定装置から得られる排気ガスＣの成分組成に基づいて、触媒反応装置１による有機物質Ｂの製造が効率的に行えるように設定することが好ましい。 In the synthetic gas supply step, the synthetic gas A is supplied from the synthetic gas source (not shown) to the synthetic gas inlet of the catalytic reaction device 1 through the synthetic gas supply line 2. Syngas A is, for example, a mixed gas containing carbon monoxide, hydrogen, carbon dioxide and nitrogen. The synthetic gas is preferably produced by treating a raw material gas such as a raw material gas generated from a waste incinerator and a raw material gas generated from a steel mill. The amount of the synthetic gas A supplied to the catalytic reaction device 1 is the component composition of the synthetic gas A obtained from the measuring device installed in the synthetic gas supply line 2 and the exhaust gas obtained from the measuring device installed in the exhaust gas measuring line 7. It is preferable to set so that the organic substance B can be efficiently produced by the catalytic reaction device 1 based on the component composition of C.
　合成ガスＡの成分組成は、原料ガスの組成の変動等の影響により、変動する場合がある。合成ガスＡの成分組成が変動する場合、原料ガスＡの各構成成分の原料ガスＡに対する含有割合の変動幅は、通常、標準的な含有割合に対して±１～３０％の範囲内である。例えば、合成ガスＡが一酸化炭素を含む場合であって、合成ガスＡ中の一酸化炭素の標準的な含有割合が３０体積％であるとき、変動幅が±３０％であるとは、合成ガスＡ中の一酸化炭素の含有割合が、２１体積％（－３０％変動）～３９体積％（＋３０変動）体積％の範囲で変動することをいう。 The component composition of syngas A may fluctuate due to the influence of fluctuations in the composition of the raw material gas. When the component composition of the synthetic gas A fluctuates, the fluctuation range of the content ratio of each component of the raw material gas A to the raw material gas A is usually in the range of ± 1 to 30% with respect to the standard content ratio. .. For example, when the synthetic gas A contains carbon monoxide and the standard content ratio of carbon monoxide in the synthetic gas A is 30% by volume, the fluctuation range is ± 30%. It means that the content ratio of carbon monoxide in the gas A fluctuates in the range of 21% by volume (-30% fluctuation) to 39% by volume (+30 fluctuation) by volume.
　有機物質合成工程では、触媒反応装置１の、触媒を含む反応部において、合成ガスＡからの有機物質Ｂの合成が行われる。有機物質Ｂとしては、例えば、アルコール、有機酸、脂肪酸、油脂、ケトン、バイオマス又は糖である。アルコールの具体例はエタノールであり、有機酸の具体例は酢酸である。有機物質Ｂとしては、エタノールが特に好ましい。合成された有機物質Ｂは、触媒反応装置１の有機物質出口から、有機物質抜取ライン３を通じて、触媒反応装置１の外部に抜き取る。 In the organic substance synthesis step, the organic substance B is synthesized from the syngas A in the reaction section containing the catalyst of the catalyst reaction device 1. Examples of the organic substance B include alcohols, organic acids, fatty acids, fats and oils, ketones, biomass or sugars. A specific example of an alcohol is ethanol, and a specific example of an organic acid is acetic acid. Ethanol is particularly preferable as the organic substance B. The synthesized organic substance B is extracted from the organic substance outlet of the catalyst reaction device 1 to the outside of the catalyst reaction device 1 through the organic substance extraction line 3.
　排気ガス排出工程では、触媒反応装置１の排気ガス出口に接続された排気ガス排出ライン４を通じて、排気ガスＣを排出する。排気ガスＣは、合成ガスＡのうち有機物質Ｂの合成に使われなかった余剰分の他に、有機物質Ｂの副生物の少なくとも一部と、反応部に含まれる物質の一部とを含むことがある。このような有機物質Ｂの副生物の少なくとも一部及び反応部に含まれる物質の一部は、通常、蒸気、液体及び泡から選択される１種以上の状態で、混入物として、排気ガスＣに含まれる。このような混入物が、測定装置９内部に侵入すると、測定装置９の動作不良、故障の原因となる。また、このような混入物は、排気ガス測定ライン７の閉塞を引き起こし、排気ガスＣの成分組成の測定が不可能になる。 In the exhaust gas discharge process, the exhaust gas C is discharged through the exhaust gas discharge line 4 connected to the exhaust gas outlet of the catalyst reaction device 1. Exhaust gas C contains at least a part of by-products of organic substance B and a part of substances contained in the reaction part, in addition to the surplus of synthetic gas A that was not used for the synthesis of organic substance B. Sometimes. At least a part of the by-product of the organic substance B and a part of the substance contained in the reaction part are usually in one or more states selected from vapors, liquids and bubbles, and are used as contaminants in the exhaust gas C. include. If such a contaminant enters the inside of the measuring device 9, it causes a malfunction or failure of the measuring device 9. In addition, such a contaminant causes the exhaust gas measurement line 7 to be blocked, making it impossible to measure the component composition of the exhaust gas C.
　混入物除去工程では、排気ガスＣに含まれる蒸気、液体及び泡沫のうち少なくとも１種の状態の混入物を排気ガスＣから分離除去する。排気ガス排出工程により排出された排気ガスＣは、排気ガス排出ライン４、流路切替器５、及び排気ガス測定ライン７を経由して、排気ガス測定ライン７の途中に配置された分離装置８に導かれる。分離装置８において、泡沫液体分離装置８ａによる排気ガスＣからの泡沫及び液体の分離除去を行い、次いで、蒸気分離装置８ｂによる排気ガスＣからの蒸気の分離除去を行う。排気ガスＣから泡沫及び液体を分離除去する方法としては、例えば、泡沫を切断して気体と液体に分離し、液体化した泡沫及び泡沫とは別に含まれていた液体を除去する方法が挙げられる。排気ガスＣから蒸気を分離除去する方法としては、例えば、蒸気を液化して気体と分離し、液化した蒸気を除去する方法が挙げられる。混入物除去工程では、分離装置８によって、排気ガスＣに含まれる蒸気の５０質量％以上、液体の８０質量％以上、及び泡沫の８０質量％以上を分離除去することが好ましい。 In the contaminant removal step, contaminants in at least one state of vapor, liquid and foam contained in the exhaust gas C are separated and removed from the exhaust gas C. The exhaust gas C discharged in the exhaust gas discharge process passes through the exhaust gas discharge line 4, the flow path switch 5, and the exhaust gas measurement line 7, and is a separator 8 arranged in the middle of the exhaust gas measurement line 7. Guided to. In the separation device 8, the foam liquid separation device 8a separates and removes the foam and the liquid from the exhaust gas C, and then the vapor separation device 8b separates and removes the vapor from the exhaust gas C. Examples of the method for separating and removing the foam and the liquid from the exhaust gas C include a method of cutting the foam to separate the gas and the liquid and removing the liquefied foam and the liquid contained separately from the foam. .. Examples of the method of separating and removing the vapor from the exhaust gas C include a method of liquefying the vapor, separating it from the gas, and removing the liquefied vapor. In the contaminant removal step, it is preferable that the separation device 8 separates and removes 50% by mass or more of the vapor contained in the exhaust gas C, 80% by mass or more of the liquid, and 80% by mass or more of the foam.
　排気ガス測定工程では、排気ガスＣの成分組成を測定する。排気ガスＣの成分組成を分析する方法としては、例えば、ガスクロマトグラフィー（ＧＣ）法、マススペクトル（ＭＳ）法、ガスクロマトグラフィー－質量分析（ＧＣ－ＭＳ）法、フーリエ変換赤外分光（ＦＴＩＲ）法等が挙げられる。測定装置９に流入する排気ガスＣの流量は、特に限定されないが、０．０１～１ｍ３／ｈｒの範囲が好ましい。 In the exhaust gas measuring step, the component composition of the exhaust gas C is measured. Examples of the method for analyzing the component composition of exhaust gas C include gas chromatography (GC) method, mass spectrum (MS) method, gas chromatography-mass spectrometry (GC-MS) method, and Fourier transform infrared spectroscopy (FTIR). ) Law, etc. The flow rate of the exhaust gas C flowing into the measuring device 9 is not particularly limited, but is preferably in the range of 0.01 to 1 m 3 / hr.

Can be measured continuously.
　上述の実施形態では、分離装置８において、泡沫液体分離装置８ａによる処理後に蒸気分離装置８ｂによる処理を行っているが、これに限定されない。例えば、ミストセパレータやノックアウトポッドを冷却し、泡と同時に蒸気も除去できる構成にすることによって、泡沫液体分離装置８ａ及び蒸気分離装置８ｂによる処理を同時に行える構成としたりしてもよい。 In the above-described embodiment, the separation device 8 performs the treatment by the vapor separation device 8b after the treatment by the foam liquid separation device 8a, but is not limited to this. For example, the mist separator and the knockout pod may be cooled so that the vapor can be removed at the same time as the bubbles, so that the treatment by the foam liquid separation device 8a and the vapor separation device 8b can be performed at the same time.

　［結果の説明］
　実施例１では、有機物を含む泡沫及び液体を排気ガスと分離でき、排気ガスの連続測定ができた。これに対して、比較例１では、泡沫及び液体が測定装置に侵入してしまい、排気ガスの連続測定ができなかった。比較例２～４では、有機物を含む泡及び液体の分離が不十分であり、測定結果が得られなかった。このことから、前段として泡沫液体分離装置による泡沫及び液体の分離及び除去を行い、後段として蒸気分離装置による蒸気の分離及び除去を行うことで、測定装置に泡沫及び液体が侵入することがなく、排気ガスの連続的な測定を行えることがわかる。 [Explanation of results]
In Example 1, bubbles and liquids containing organic substances could be separated from the exhaust gas, and the exhaust gas could be continuously measured. On the other hand, in Comparative Example 1, bubbles and liquid invaded the measuring device, and continuous measurement of exhaust gas could not be performed. In Comparative Examples 2 to 4, the separation of bubbles and liquids containing organic substances was insufficient, and measurement results could not be obtained. From this, by separating and removing the foam and liquid by the foam liquid separation device in the first stage and separating and removing the vapor by the vapor separation device in the second stage, the foam and liquid do not enter the measuring device. It can be seen that continuous measurement of exhaust gas can be performed.
　本発明の有機物質製造システムは、触媒反応装置から排出する排気ガスの成分組成を連続的に測定できるので、合成ガスの成分組成の変動に対応した有機物質の生産を可能とする。そのため、エタノール等の有機物質を高効率で製造することができ、合成ガスの利用率を高めることができる。 Since the organic substance production system of the present invention can continuously measure the component composition of the exhaust gas discharged from the catalytic reaction device, it is possible to produce an organic substance corresponding to the fluctuation of the component composition of the synthetic gas. Therefore, an organic substance such as ethanol can be produced with high efficiency, and the utilization rate of synthetic gas can be increased.
