Description
(a) 急冷油を供給してその定常状態のインベントリーを維持する工程、
(b) 流出物ガスを急冷油と接触させて流出物ガスを冷却し、触媒微粒物を洗浄除去して、微粒物を本質的に含まない冷却流出物ガスを得る工程、
(c) 急冷油を接触工程からインベントリーへ戻す工程、
(d) 急冷油をインベントリーから接触工程へ連続的に再循環する工程、
(e) インベントリーからの急冷油の流れから微粒物を分離し、それら微粒物を回収し、前記微粒物がインベントリー中に蓄積しないように保つ工程、及び
(f) 分離工程から回収された前記微粒物をスラリーにする工程、
を含む。
本発明は、軽質FCC流出物からの微粒物を回収し、使用済み触媒を再生するための方法及び装置にある。本明細書及び特許請求の範囲で用いられている軽質FCC単位装置又は方法は、FCC上昇管への炭化水素供給原料が、非常に低い残留物含有量を有し、そのため触媒に付着した炭素では、補充燃料源を用いずに、再生するための燃焼を持続するのには不充分であり、慣用的スラリー油回収のためには上昇管流出物中の燃料油は不充分であり、即ち、上昇管からの反応器流出物ガス中の炭化水素で288℃(550°F)より大きい大気圧沸点を有するものは2重量%未満しかない。しかし、この量が2重量%より大きくなれば、場合によりフィルターを迂回し、この材料をスラリーとして用いることができる。FCC法は、流動接触反応装置を包含し、好ましくは大きなオレフィン含有量を有する軽質炭化水素供給物流を、プロピレン及びエチレンに富む生成物スレート(slate)へ転化する。反応器からの典型的なプロピレン/エチレン生成物比は、約2.0になりうる。FCC反応器は非常に融通のきくものであって、それはオレフィンプラント又は製油所から入手できるオレフィンに富む多くの流れ、例えば、オレフィンプラントC4/C5流、製油所C4、熱分解又は接触分解法で生成した軽質ナフサ等のようなものを処理することができる。
