Description
最初に候補アミン混合物の吸収速度およびだ脱着速度について工業標準の30重量%のMEA(5M)と比較して見当をつけるため、スクリーニング実験を実施した。吸収速度は、吸収塔に必要な高さと直接関係のある吸収剤の物質移動促進特性の尺度である。反応速度の速い吸収剤を用いればその分、回収塔の高さを低くすることができる。溶媒の循環能とは、吸収条件下で達成可能なCO2負荷量と、脱着条件下で達成される最小CO2負荷量との差のことである。燃焼排ガスからの吸収/脱着は、最も重要な機序の温度スイングに基づくものである。吸収能の温度感受性が著しく高い溶媒では循環能が高くなるため、CO21モルを回収するのに必要な液体の循環量が少なくなり、必要なエネルギーも少なくなる。実際の工程では、脱着を通常110〜130℃で実施する。40℃(吸収スクリーニング条件)から80℃までの昇温に基づく脱着スクリーニング曲線により、様々な溶媒について重要な温度感受性および循環能の相対比較ができる。
図1は、水性溶媒中のアルカノールアミン濃度を20重量%のAMP+30重量%のAPの溶液、26.7重量%のAMP+22.5重量%のAPおよび30重量%のMEAとして得られた、CO2濃度に対する吸収速度の結果を示し、図2は同じ吸収剤のCO2濃度に対する脱着速度を示している。
ガラス製の反応槽内の予めCO2を負荷したアミン溶液中に空気とCO2とを含有する反応ガスを焼結ガラスにより拡散させて酸化分解実験を実施した。反応ガスのガス流速および組成をマスフローコントローラ(MFC)によって制御する。55℃の一定温度にするため、反応槽には水浴と接続した恒温ジャケットを取り付ける。反応槽上部に水道水で冷却される400mmの強力な冷却器を2つ接続する。ガスは冷却器を通った後、ガス洗浄瓶を経てから換気ドラフトに行くようにする。実験を約500時間実施し、一定間隔でアミン分析用に試料を採取する。開始時と終了時のアミン濃度の差がアミン分解の尺度となる。
ステンレス鋼製セル(316SS、OD=1/2インチ(12.7mm)、厚さ=1.7mm)を用いてCO2−アミン−水系の腐食作用に関する実験を実施した。各セルは体積が約27cm3であり、Swagalokバルブを取り付けた。1組の実験にセルを5個用いた。各セルにN2(99.999%)を流してセル内の空気を追い出した。次いで、一定量のCO2負荷アミン溶液(約15cm3)をセルに注入し、セル内に空気が存在しないようにするため、バルブを閉じる前にセル上部にN2を流した。次いで、セルを強制対流式オーブン内に135℃で5週間置いた。週1回、セルを1個取り出して誘導結合プラズマ質量分析(ICP−MS)による金属の分析に供した。
図5に示される燃焼後CO2吸収のための小規模のパイロットプラントで試験キャンペーンを実施した。天然ガスに適用され得るプロパンバーナによって発生した排ガスまたは空気との混合もしくはCO2の再循環による石炭由来の燃焼排ガスがそれぞれ、排気管1から導入される。排気管の排ガスは直接接触冷却器2に導入され、そこで水との向流によって洗浄および加湿される。次いで冷却および加湿された排ガスは吸収塔に導入され、図示されていない充填部で、リーンアミンの管4から導入された水性吸収剤と向流する。CO2を吸収したリッチ吸収剤は吸収塔底部で収集され、リッチ吸収剤の管5から取り出され、一方、CO2リーン排ガスは、洗浄区間で洗浄水冷却回路19、19’を再循環する水により洗浄された後、リーン排気管6から環境中に放出される。
