(JA) バイオガス中の気体種の濃度を測定する方法
Abrégé
(JA) 【解決手段】本発明は、例えばバイオガス処理プラントまたはバイオガスを用いるシステムのパイプ(20)内を流れるバイオガス(10)中に含まれる気体状の化学種の濃度をその場で測定する方法に関する。本発明に係る方法は、光源(41)と分光計(44)とを含む光学的測定システム(40)によって実施される。光源(41)は、パイプ内の測定ゾーン(21)内のバイオガス(10)を通してUV放射(42)を発する。分光計(44)は、バイオガス(10)を通過した前記UV放射の少なくとも一部を検出し、バイオガスを通過したUV放射の一部の波長の関数として光強度のデジタル信号(50)を生成する。次いで、化学種の濃度を光強度のデジタル信号(50)から求める。
