　上記（８）に記載の構成によれば、発電設備（４０）に供給される副生水素ガスの一部を第１水素供給ライン（１１）に流入させることができる。そのため、合成物の生産に必要な分だけ副生水素ガスを第１水素供給ライン（１１）に導き、合成物の生産に不要な副生水素ガスについては発電設備（４０）に導くことができる。その結果、二酸化炭素回収装置（５０）から排出される副生水素ガスを無駄なく利用することが可能となる。また、二酸化炭素回収装置（５０）の稼働率を向上させることができる。 According to the configuration described in (8) above, a part of the by-product hydrogen gas supplied to the power generation facility (40) can flow into the first hydrogen supply line (11). Therefore, the by-product hydrogen gas required for the production of the compound can be guided to the first hydrogen supply line (11), and the by-product hydrogen gas not required for the production of the compound can be guided to the power generation facility (40). .. As a result, the by-product hydrogen gas discharged from the carbon dioxide capture device (50) can be used without waste. In addition, the operating rate of the carbon dioxide capture device (50) can be improved.
