Description

本考案は、空気中の二酸化炭素の直接捕集技術の分野に属し、具体的には連続空気中の二酸化炭素の直接捕集システムに関する。 FIELD OF THE INVENTION The present invention belongs to the field of direct carbon dioxide capture technology in the air, and specifically relates to a direct carbon dioxide capture system in continuous air.

１９９９年、米国のロスアラモス国立研究所（Ｌｏｓ Ａｌａｍｏｓ Ｎａｔｉｏｎａｌ Ｌａｂｏｒａｔｏｒｙ）のＬａｃｋｎｅｒは気候変動を緩和するために直接空気炭素捕集（ＤＡＣ）技術という概念を提案した。長年の研究を経て、科学研究者は多くのＤＡＣの方法と材料を提案した。現在、ＤＡＣ技術は、すでに実行可能なＣＯ２排出削減技術の１つと考えられている。空気中のＣＯ２は吸着剤によって捕集され、捕集終了の吸着剤は圧力や温度を変えることによって吸着剤の再生を行い、再生された吸着剤がＣＯ２捕集に循環され、純ＣＯ２は貯蔵される。 In 1999, Lackner of Los Alamos National Laboratory, USA, proposed the concept of direct air carbon capture (DAC) technology to mitigate climate change. After years of research, scientific researchers have proposed many DAC methods and materials. At present, DAC technology is already considered as one of the viable CO2 emission reduction technologies. The CO2 in the air is captured by the adsorbent, and the adsorbent that has finished capturing is regenerated by changing the pressure and temperature. 2 is stored.

過去の半世紀以上にわたって、人類の活動によって世界のＣＯ２排出量は年々増加している。大気中のＣＯ２濃度は１９６０年の３１０ｐｐｍ前後から２０１９年の４１０ｐｐｍに急激に増加し、現在世界のＣＯ２排出量は毎年３５０億トンを超えている。負の炭素排出技術研究の焦点として、直接空気炭素捕集技術は２０１９年に「マサチューセッツ工科大学科学技術評論」の世界１０大画期的な技術の１つに選ばれた。カーボンニュートラル目標の提出に伴い、全産業チェーンの炭素削減はすでに共通認識となっており、直接空気炭素捕集技術は早急に更なる発展が必要である。 Over the past half century or more, global CO2 emissions have increased year by year due to human activities. Atmospheric CO2 concentration increased sharply from around 310 ppm in 1960 to 410 ppm in 2019, and now global CO2 emissions exceed 35 billion tonnes annually. As the focus of negative carbon emission technology research, direct air carbon capture technology was selected as one of the world's top ten breakthrough technologies in 2019 by the "Massachusetts Institute of Technology Science and Technology Review". With the submission of the carbon neutral target, carbon reduction in the entire industrial chain has already become a common recognition, and direct air carbon capture technology needs further development as soon as possible.

ＤＡＣ技術とＣＣＳ（ｃａｒｂｏｎ ｃａｐｔｕｒｅ ａｎｄ ｓｔｏｒａｇｅ炭素捕集とアーカイブ）技術との違いは表１に示す。

Figure 0003240788000002
Table 1 shows the difference between DAC technology and CCS (carbon capture and storage) technology.
Figure 0003240788000002

ＣＣＳ技術とは異なり、ＤＡＣの技術的特徴は以下の通りである。
（１）分散した排出源ＣＯ２の捕集に使用可能である。
（２）取り付け場所の選択は比較的柔軟であり、捕集エネルギー消費と輸送コストを削減するために、再生可能なエネルギーが豊富で炭素貯蔵利用位置に近い場所を選択することができる。
（３）ＮＯｘとＳＯ２などのガス不純物の影響を考慮する必要がない。直接空気炭素捕集技術の主な難点は空気中のＣＯ２分圧が低く（４０Ｐａ）、濃度が低く（４００ｐｐｍ）、ＣＯ２吸着／再生効率が低く、再生エネルギー消費とコストが高いことである。 Different from CCS technology, the technical features of DAC are as follows.
(1) It can be used to capture CO2 from distributed sources.
(2) The choice of installation location is relatively flexible, and a location that is abundant in renewable energy and close to carbon storage utilization locations can be selected to reduce capture energy consumption and transportation costs.
(3) There is no need to consider the effects of gas impurities such as NOx and SO2. The main drawbacks of direct air carbon capture technology are low CO2 partial pressure in air (40 Pa), low concentration (400 ppm), low CO2 adsorption/regeneration efficiency, and high regeneration energy consumption and cost. .

現在、物理吸着法を用いたＤＡＣ技術では、一般的に接触器が矩形塔設備であり、接触器内に埋め込まれたアミン吸着剤が多孔質、ハニカムのセラミックブロックに付着してＣＯ２を吸着する。吸着完了後、低温蒸気（８５～１００℃）でＣＯ２を脱着収集する。Ｇｌｏｂａｌ Ｔｈｅｒｍｏｓｔａｔ社は、アミノ重合体吸着剤を使用してシステム全体の循環時間を３０分以下に短縮したと主張しており、これは基本的に業界をリードしているレベルを表している。このようなＤＡＣ技術に存在する大きな課題の１つは、吸着／再生過程の不連続性であり、全体の効率の向上に影響を与えている。 At present, in DAC technology using physical adsorption method, generally the contactor is a rectangular tower equipment, and the amine adsorbent embedded in the contactor adheres to the porous, honeycomb ceramic block to adsorb CO2 . do. After adsorption is complete, CO 2 is desorbed and collected with low temperature steam (85-100° C.). Global Thermostat claims to have reduced the circulation time of the entire system to less than 30 minutes using the amino polymer adsorbent, which basically represents an industry leading level. One of the major challenges that exist in such DAC technology is the discontinuity of the adsorption/regeneration process, affecting the overall efficiency improvement.

本考案は、連続空気中の二酸化炭素の直接捕集システムを提供し、吸着、脱着、再生などの過程を段階的に展開することにより、空気中の二酸化炭素の直接捕集全過程の連続化運行を実現し、システム利用効率を大幅に向上させることができることを目的とする。 The present invention provides a direct collection system for carbon dioxide in continuous air, and the whole process of direct collection of carbon dioxide in air is continuous through the stepwise development of adsorption, desorption, regeneration and other processes.
