Description
ある従来の複分解処理をシミュレーションする。C4供給物402におけるイソブテン400を分離器404を介して除去した後、該供給物を従来の複分解反応器406に送る。エチレン408を複分解反応器406に或る割合で供給することにより、従来の複分解反応器406への入口におけるエチレン対n−ブテンモル比を1.8(38.5kg/hエチレン供給)に維持する。96%の全体C4利用率および94%の全体C2利用率を用いて複分解反応器排出物410をシミュレーションし、それを、次いで、C2およびC4パージならびに再循環流れ420、422、424、および426を伴う状態で、C2412、C3414、C4416およびC5+418に分離する。シミュレーションの詳細および結果を表4に示す。従来の複分解、自動複分解および分解で生成されたプロピレンは、112.4kg/hである。
図1に示されるものと同様の処理を示す。エチレン対n−ブテン比は1.79に保たれた。それぞれ96%および94%のC4利用率およびC2利用率を用いて複分解反応器18をシミュレーションする。フローライン46を介する分解器44に対しての追加のC4+供給物は供給されず、分解器C4を分別器12に再循環させる。このシミュレーションの詳細および結果を表5に示す。従来の複分解および分解で生成されたプロピレンは、128.2kg/hである。
実施例2も、図1に示される処理と同様の処理をシミュレーションし、そこにおいては、分解器からの再循環流れをフローライン60を介して分解器に送り戻し、分解器からの再循環は分別器12には送られない。エチレン対n−ブテン比は1.79に維持される。それぞれ96%および94%のC4利用率およびC2利用率を用いて複分解反応器18をシミュレーションする。フローライン46を介する分解器44に対しての追加のC4+供給物は供給されず、分解器C4を分別器12に再循環させる。このシミュレーションの詳細および結果を表6に示す。従来の複分解および分解で生成されたプロピレンは、124.6kg/hである。
この実施例に対する処理構成は、実施例1と同じであるが、以下の相違点を伴う。エチレン対n−ブテン比は、実施例1の1.8と比較して1.0に維持され、混合されたC4供給物におけるイソブテンの約50%が、分別器12を通過して従来の複分解反応器18に到達することを許される。これらの供給物変更は、複分解反応器の上流側の脱イソブチレン化部における規格を緩和する。加えて、イソブテンは、複分解によるプロピレン生成において、エチレンの半分ほどの生産性であり、結果として得られる枝分かれC5オレフィン(2−メチル2−ブテン)を、フローライン36を介して分解器44に送ることにより、追加的な軽質オレフィンを生成してもよい。このシミュレーションの詳細および結果を表7に示す。従来の複分解および分解で生成されたプロピレンは、117.1kg/hである。
この実施例の処理構成は実施例1と同じであるが、ただし以下の相違点がある。従来の複分解反応器18の入口におけるエチレン対n−ブテン比は、処理における正味のエチレン消費がないよう、つまり従来の複分解反応器に供給されるエチレンの量が分解器において生成されるエチレンと同じであるよう調整される。加えて、実施例3におけるように、抽残物におけるイソブテンの約50%を、従来の複分解反応器18に通過させる。このシミュレーションの詳細および結果を表8に示す。従来の複分解および分解で生成されたプロピレンは、83.3kg/hである。
異なる供給物を用いながら、図5に示されるそれと同様に、独立型分解器に対してシミュレーションを行なう。用いられる供給物は:
a) C4抽残物(n−ブテンおよびイソブテンを代表する)、
b) 2−メチル2−ブテン(イソペンテンを代表する)、
c) 1−ヘキセン(n−ヘキセンを代表する)、および
d) 2−メチル2−ペンテン(イソヘキセンを代表する)、を含む。
自動複分解および従来の複分解の両方を含む、図3に示されるものと同様の処理をシミュレーションする。エチレン対n−ブテン比は、上記の実施例4と同様に、0の正味のエチレン消費をもたらす結果となるよう調整される。それぞれ96%および94%のC4利用率およびC2利用率を用いて複分解反応器18をシミュレーションする。このシミュレーションの詳細および結果を表10に示す。従来の複分解、自動複分解および分解で生成されたプロピレンは、83.4kg/hである。
