Abstract
【解決手段】熱分解カーボンを含む乾留ガスを冷却して回収油とする油分を液化する工程と、液化した油分を貯留槽4に回収油として貯留するとともに、貯留槽内の回収油中に冷却された乾留ガスを導入して回収油中に気泡7を発生させて乾留ガス中の熱分解カーボンと回収油との固液混合により熱分解カーボンを回収油中に移行させて除去する工程と、熱分解カーボンが除去された乾留ガスを貯留槽4の上部から抜き出す工程と、貯留槽4の下部から回収油を抜き出し、固液分離装置9にて熱分解カーボンを取り除いて油分を回収する工程と、貯留槽4の上部から回収油を抜き出し、乾留ガスの冷却油として循環させる工程からなる。

Description
また、仮に引用文献2のように乾留ガスを吸収液に空気の吹込みで形成された泡で除去しようとすると、乾留ガスが燃焼して爆発するおそれがあるので危険であり、また、N2で気泡を形成すると、乾留ガスカロリーが下がり回収ガスの価値が下がる。
