図1に示されるように、サービス事業者装置21は、サービス事業者20が運用する装置である。削減事業者装置31は、二酸化炭素削減事業者30が運用する装置である。図2に示されるように、サービス事業者装置21は、サービス事業者20がユーザ1のアプリ110の利用実績81を把握し、利用実績81に応じた二酸化炭素削減作業を二酸化炭素削減事業者30へ依頼し、削減実績値84を二酸化炭素排出監督者40へ報告して二酸化炭素クレジット85を受信し、二酸化炭素クレジット85に応じた貢献ポイント86をユーザ1に付与するという一連の動作を行うための装置である。削減事業者装置31は、二酸化炭素削減事業者30が二酸化炭素削減の依頼情報83を受け、削減実績値84をサービス事業者装置21に送るという動作を行うための装置である。
本開示の実施形態2は、サービス事業者20により提供されたアプリケーションをユーザ端末11において利用するユーザ1が、アプリ110の利用実績81に応じた二酸化炭素クレジット85を二酸化炭素排出監督者40から獲得する二酸化炭素削減促進システム10である。以下のシステムの説明においてはユーザ1を代表として説明するが、実施形態におけるユーザは複数であってユーザ数は限定されない。また、実施形態1と重複する説明は省略する。
実施形態2におけるユーザ端末11の構成と機能は、実施形態1におけるユーザ端末11と類似する。実施形態1と同じ構成については記載を省略する。図3を参照して、実施形態2においては、ポイント受信部130は、監督者装置41から二酸化炭素クレジット85を受信する。すなわち、貢献ポイント86として二酸化炭素クレジット85を受け取ると読み替えればよい。
サービス事業者装置21は、サービス事業者20が運用する装置である。サービス事業者装置21は、サービス事業者20がユーザ1のアプリ110の利用実績81を把握し、利用実績81に応じた二酸化炭素削減作業を二酸化炭素削減事業者30へ依頼し、削減実績値84をユーザ毎の分配実績値87として整理したうえで二酸化炭素排出監督者40へ報告するという一連の動作を行うための装置である。削減事業者装置31の構成と機能は、実施形態1と同じであり、説明を省略する。
二酸化炭素削減事業者30が運用する二酸化炭素削減装置32について説明する。二酸化炭素削減装置32は、大気や各種排気ガスなどの気体から二酸化炭素を削減・捕捉・削減する装置である。本開示に示す二酸化炭素削減装置32は、二酸化炭素を削減する捕捉装置、およびその付帯設備、配管、制御装置、電源等を含めた設備の総称である。
捕捉装置の例として、溶液中の二酸化炭素捕捉材を用いて二酸化炭素を捕捉産物に固定して削減する装置を説明する。本開示の二酸化炭素削減促進システム10に適用可能な捕捉装置は以下に説明する装置に限定されず、ガス中の二酸化炭素を分離削減可能な種々の装置を適用することができる。以下に具体的に説明する捕捉装置は、簡易な構成により二酸化炭素を削減・削減でき、かつガス中の二酸化炭素を捕捉産物として固定して削減可能な特徴により、本開示の二酸化炭素削減促進システム10に適用できる装置である。
二酸化炭素捕捉材510は、粒子状または粉末状である。本実施形態において、二酸化炭素捕捉材510は、鉄または鉄化合物を主成分とする粒子である。鉄を主成分とする二酸化炭素捕捉材510は例えば、鉄および鉄合金である。鉄合金は、鉄とマンガン、クロム、モリブデン、アルミニウム、銅、亜鉛、ニッケル等を含んでもよい。鉄化合物としては、水酸化鉄(II)、ヘキサシアノ鉄(II)酸鉄(II)等が挙げられる。なお、二酸化炭素捕捉材510は、鉄以外の層状複水酸化物、塩基性金属酸化物、塩基性金属水酸化物であってもよい。
支持体571には、複数の二酸化炭素捕捉材510が配置される。捕捉装置500が支持体571を備えることで、二酸化炭素捕捉材510を安定的に保持することができる。また、二酸化炭素捕捉材510に付着した炭酸鉄である捕捉産物を容易に削減して洗浄することができる。
供給部530は、二酸化炭素を含む気体である処理対象ガス512を溶液520に供給する。供給部530は、例えば貯留槽501の下部から貯留槽501内に二酸化炭素を含む気体を供給可能な供給管を含む。
溶液520は、複数の二酸化炭素捕捉材510を常時覆っている。捕捉装置500では、複数の二酸化炭素捕捉材510が溶液520中に浸漬されている。
溶解促進機構540は、上述のように二酸化炭素の溶液520への溶解を促進する。捕捉装置500は、溶解促進機構540を備えることで、溶液520中の二酸化炭素量を増大しやすい。このため、二酸化炭素の捕捉効率がより向上される。
分散機構550は、複数の二酸化炭素捕捉材510を溶液520中で分散させる。分散機構550は、複数の二酸化炭素捕捉材510の平均粒子径を維持する。分散機構550は、複数の二酸化炭素捕捉材510が凝集しやすい場合に、特に有効に機能する。分散機構550としては、溶液520に水流を発生させるものが使用でき、超音波発生装置、攪拌装置等を用いることができる。図8は分散機構550として超音波発生装置を示している。また、分散機構550として磁力によって二酸化炭素捕捉材510を誘引、分画および固定(特定の位置に固定)する装置も使用できる。このような装置は、例えば磁気分離装置である。
溶液調整機構560は、例えば溶液520のpHが上昇した際に、溶液520に酸性物質を供給する。酸性物質は例えば、上述した塩およびこの塩が溶解した溶液である。
貯留槽501には、溶液520が貯留される。また、捕捉装置500は、溶液520から放出された気体を排出する脱気促進機構503を備える。本実施形態において、貯留槽501は、上述した炭酸化促進剤521を二酸化炭素捕捉材510および支持体571から間隔を空けて配置するための多孔質膜502を有する。
図9に示す通り、多孔質膜502は、例えば炭酸化促進剤521と二酸化炭素捕捉材510および支持体571とを貯留槽501内において上下に隔てる。炭酸化促進剤521が多孔質膜502よりも下側に配置され、二酸化炭素捕捉材510および支持体571が多孔質膜502よりも上側に配置されてもよい。このように多孔質膜502が炭酸化促進剤521と二酸化炭素捕捉材510および支持体571とを隔てることによって、上述した通り、炭酸化促進剤521を種結晶とした炭酸鉄等を容易に削減することができる。
脱気促進機構503は、貯留槽501の上部に配置される。脱気促進機構503は、溶液520中を上昇して溶液520の液面から放出された気体を捕捉装置500の外に排出する。さらに、脱気促進機構503は、溶液520に接する気体の圧力を低減するように、気体を当該捕捉装置500の外に排出する。このように溶液520に接する気体の圧力を低減することで、脱気促進機構503は溶液520の溶存酸素の含有量を低減させる。これにより、溶液520中の溶存酸素による酸化作用が低減され、溶液520中の2価の鉄イオンの比率が増大した状態を維持しやすい。
