本発明は固体アミンによるＣＯ２除去装置の制御方法に
関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for controlling a CO2 removal device using a solid amine.
（従来技術）
固体アミンによるＣＯ２除去プロセスにおいて、固定ア
ミンの再生には水蒸気による直接加熱再生方式が用いら
れている。このプロセスの吸着−再生工程での固体アミ
ンの保有水分は次のように変化する。(Prior Art) In a CO2 removal process using a solid amine, a direct heating regeneration method using steam is used to regenerate the fixed amine. The water content of the solid amine during the adsorption-regeneration step of this process changes as follows.
１）吸着工程における保有水分の変化
固体アミン層を通過する供給ガスの温度、湿度及び流速
に応じた分だけ固体アミン粒子表面から保有水分が蒸発
し減少する。この現象は、固体アミン層を通過するガス
中の水分と固体アミン粒子表面の水分との間に平衡関係
が成立するまで続くので、固体アミンから失われる保有
水分の総量は、扱方時間または平衡到達時間（平衡に達
するまでに要する時間）の短かい方で定まる。1) Change in retained moisture in the adsorption process The retained moisture evaporates and decreases from the solid amine particle surface by an amount corresponding to the temperature, humidity, and flow rate of the supplied gas passing through the solid amine layer. This phenomenon continues until an equilibrium relationship is established between the moisture in the gas passing through the solid amine layer and the moisture on the surface of the solid amine particles, so the total amount of retained moisture lost from the solid amine depends on the handling time or the equilibrium It is determined by the shorter of the arrival time (time required to reach equilibrium).
２）再生工程における保有水分の変化
固体アミンの再生には、通常１００〜１２０℃の飽和水
蒸気が用いられる。固体アミン層に供給された水蒸気は
、固体アミン層内で凝縮し、この時に発生する潜熱によ
って吸着されたＣＯ２は固体アミンから脱離し、固体ア
ミンは再生される。2) Change in water content in the regeneration process Saturated steam at 100 to 120°C is usually used to regenerate solid amines. The water vapor supplied to the solid amine layer is condensed within the solid amine layer, and the CO2 adsorbed by the latent heat generated at this time is desorbed from the solid amine, and the solid amine is regenerated.
この凝縮した水の内、一部は固体アミンに吸着されるこ
とになる。吸着される水分の総量は吸着工程での固体ア
ミンの乾燥の度合、固体アミン自体が保有可能な水ｆｆ
１（飽和吸着水量）、固体アミンの水分成層速度及び再
生時間等によって定まる。A portion of this condensed water will be adsorbed by the solid amine. The total amount of water adsorbed depends on the degree of drying of the solid amine in the adsorption process and the amount of water that the solid amine itself can hold.
1 (saturated adsorbed water amount), determined by the water stratification rate of solid amine, regeneration time, etc.
以上のべたように固体アミンの保有水分は吸着工程で減
少し、再生工程で増加する。即ち、固体アミン側からみ
ると吸着工程で乾燥し、再生工程で湿潤することになる
。したがって、吸着工程で失われた水分が再生工程で補
給されるような条件下では、固体アミンは一定の範囲で
水分を保持すること−なり、安定したＣＯ２吸着性能を
維持することができる。As explained above, the water content of solid amines decreases during the adsorption process and increases during the regeneration process. That is, when viewed from the solid amine side, it dries during the adsorption process and becomes wet during the regeneration process. Therefore, under conditions where the moisture lost in the adsorption process is replenished in the regeneration process, the solid amine will retain moisture within a certain range, and stable CO2 adsorption performance can be maintained.
しかしながら、上述の関係（固定アミンの乾燥−湿潤）
を維持するためには、装置の設置場所における環境条件
（温度、湿度）を一定に保つ必要があり、環境条件が変
動すると固体アミンは乾燥。However, the above relationship (drying-wetting of fixed amines)
In order to maintain this, it is necessary to keep the environmental conditions (temperature, humidity) constant at the location where the equipment is installed, and if the environmental conditions fluctuate, the solid amine will dry out.
湿潤いずれかの方向に偏り、ＣＯ２吸着性能が低下する
。If the humidity is biased in either direction, the CO2 adsorption performance will decrease.
次に固体アミンの吸着性能と保有水分の関係についての
べる。この関係をグラフに描くと第３図のようになる。Next, we will discuss the relationship between solid amine adsorption performance and water content. If you draw this relationship on a graph, it will look like Figure 3.
ハミルトンスタンダード社（米国）が実施したＩＲＡ−
４５（米国ロームアンドハース社製、弱塩基性陰イオン
交換樹脂）でのテスト結果によれば、ＩＲＡ−４５のＣ
Ｏ２吸着性能を維持するためには、保有水分の範囲は１
８〜３５％とされている。この範囲を外れると性能が低
下することになり、その原因として以下のことが挙げら
れる。IRA conducted by Hamilton Standard (USA)
45 (manufactured by Rohm and Haas, USA, weakly basic anion exchange resin), the C of IRA-45
In order to maintain O2 adsorption performance, the retained moisture range is 1
It is said to be 8-35%. If it falls outside this range, the performance will deteriorate, and the reasons for this are as follows.
１）保有水分が下限以下の場合（ＩＲＡ−４５では１８
％以下）
固体アミンのＣＯ２吸着反応はイオン交換反応によるも
のであるが、交換基のアミン類が十分に水和されていな
いと、イオン交換反応が抑制され。1) If the retained moisture is below the lower limit (18 for IRA-45)
% or less) The CO2 adsorption reaction of solid amines is based on an ion exchange reaction, but if the amines of the exchange group are not sufficiently hydrated, the ion exchange reaction will be suppressed.
第４図（ａ）に示すように急激に吸着性能が低下する。As shown in FIG. 4(a), the adsorption performance decreases rapidly.
２）保有水分が上限以上の場合（ＩＲＡ−４５では３５
％以上）
第４図（ｃ）に示すように、吸着初期の吸着速度は低下
するもの＼、保有水分が下限以下（第４図（ａ））のよ
うな急激な低下はみられない。これは固体アミン粒子表
面に水の層ができ、ＣＯ２がイオン交換サイトに到達す
るまでの抵抗となる。つまりＣＯ２の拡散速度が低下す
ることによる現象である。2) If the retained moisture is above the upper limit (35 for IRA-45)
% or more) As shown in Figure 4(c), although the adsorption rate decreases at the initial stage of adsorption, there is no sudden decrease as seen when the retained moisture is below the lower limit (Figure 4(a)). This creates a layer of water on the surface of the solid amine particles, which provides resistance for CO2 to reach the ion exchange site. In other words, this phenomenon is caused by a decrease in the diffusion rate of CO2.
なお第４図（ｂ）は保有水分が適切な範囲（ＩＲＡ−４
５では１８〜３５％）にある場合の典型的な例で、破過
時間（固体アミン層出口にＣＯ２が吸着されずに流出し
てくるまでに要する時間）が長いことがわかる。Figure 4 (b) shows the appropriate range of retained moisture (IRA-4
5), the breakthrough time (the time required for CO2 to flow out without being adsorbed at the outlet of the solid amine layer) is long.
また固体アミンの適切な保有水分範囲は固体アミンの種
類によって変わるが、−船釣には生乾きの状態がよいと
されている。ＩＲＡ−４５の場合で説明すると、その保
有可能な水分は４０〜４５％で、適切な範囲は上述の如
く１８〜３５％である。The appropriate moisture content range for solid amines varies depending on the type of solid amine, but it is said that a half-dry state is best for boat fishing. In the case of IRA-45, the moisture content it can hold is 40-45%, with a suitable range being 18-35% as mentioned above.
以上で、吸着−再生工程での保有水分の変化及び保有水
分のＣＯ２吸着性能への影響について説明したが、従来
技術では直接的な保有水分の制御はなされておらず、環
境条件を保有水分が変動しないよう調節している程度で
あった。Above, we have explained the change in retained moisture during the adsorption-regeneration process and the influence of retained moisture on CO2 adsorption performance.However, in the conventional technology, retained moisture is not directly controlled, and environmental conditions are controlled by retained moisture. It was just an adjustment to keep it from fluctuating.
したがって、空調が整備されていないような場所におい
ては、保有水分の変動は避けられず、吸 。Therefore, in places where air conditioning is not provided, fluctuations in retained moisture are unavoidable, leading to absorption.
着性能を維持できなかった。The wearing performance could not be maintained.

The supply gas is supplied after being controlled in temperature and humidity by a temperature and humidity control device 3, and is then supplied to the adsorption reactor 1 or 2.
After CO2 is adsorbed, it is released into the environment. 4 is a steam generator for regeneration, and 5 is a CO2 analyzer. Reference numeral 6 denotes a control computer, which is connected to the temperature/humidity controller 3 and the CO0 analyzer 5.

温湿度設定のためのデータとなる。The supply gas is controlled by temperature and humidity setting signals from the control computer 6. The supply gas is adjusted to a constant temperature and humidity by the temperature and humidity control device 3, and is supplied from the upper part of the first adsorption reactor 1, and after removing CO□, is discharged from the lower part and returned to the environment. This discharged gas (hereinafter referred to as processed gas)
A part of the is led to the CO2 analyzer 5, and the CO2 concentration is a+1.
1 is determined. The measurement results are stored in the storage device of the computer 6, and serve as data for temperature and humidity settings for the temperature and humidity adjustment device in the next adsorption step.
以下第２図のフローチャートを参照してＣＯ２除去装置

作は吸着工程終了まで継続する。As soon as the first adsorption reactor 1 enters the adsorption process, the CO2 concentration in the process gas is detected at regular intervals (for example, every 30 seconds) and stored in the storage device of the control computer 6. This operation continues until the end of the adsorption step.

メモリに格納し、運転再開時の初期値とする。When the adsorption step is completed, the adsorption performance is calculated from the CO2 concentration measurement data, and it is determined whether or not the performance has deteriorated. If the performance is on the decline, the retained moisture is estimated by comparing it with the shape of the breakthrough curve according to retained moisture shown in FIG. 4, which is stored in advance in the storage device of the control computer. Furthermore, the temperature and humidity are calculated according to the deviation between the calculated retained moisture content and the optimal retained moisture content, and are used as set values for the next adsorption step. When the operation is stopped, the values are stored in a non-volatile memory such as a floppy disk and used as the initial values when the operation is restarted.

度調節のみで対応できる。The same operation will be performed for the second adsorption reactor 2, and the measurement of CO2 concentration and calculation of retained water will be performed at the same time, but this can be solved by performing the measurement in an interrupt manner or by using a computer capable of multi-jobs. It is possible. In this S, both the temperature and humidity of the supplied gas are controlled, but since the drying of normal solids is more dependent on humidity than on temperature, if there is little fluctuation in the environmental temperature, only humidity control is required. I can handle it.
