Abstract
Description
可能性のある化合物を除去する目的で、直接接触型凝縮器をオフガス流の中に前記圧縮器の上流に位置させて用いることを伴う。
内で起こさせることを包含する。その取り出したオフガス流には前記反応槽から生じた水素が入っている。冷却用媒体を循環させかつ前記オフガス流を前記冷却用媒体と接触させる能力を有する直接接触型凝縮器を用いて前記オフガス流を冷却しかつ前記オフガス流から有機化合物および水蒸気を凝縮させることができる。有機化合物および水蒸気の含有量が低下した冷オフガス流を前記直接接触型凝縮器から取り出す。
液体は前記バッフル4の開口部から最初に下方に流れた後、KOドラム1の下部を横切る横方向に流れることで、軽い方の芳香族液が重い方の水から重力で分離される。その分離された芳香族液および水の流量と凝縮したオフガス流のそれは実質的に等しく、それらはあふれ管5を通って導かれる。それらは前記凝縮器からライン14を通って出た後、主スチレン工程分離器(示していない)に戻る。その循環する冷却用水をKOドラム1からライン13に通して出させた後、冷蔵装置2に戻してもよい。
ように供給することを含めてもよい。脱水素反応を少なくとも300℃、場合により少なくとも350℃、場合により少なくとも400℃、場合により少なくとも450℃、場合により少なくとも500℃の温度で起こさせてもよい。脱水素反応を適切な如何なる圧力で起こさせてもよく、例えば大気圧以上の圧力から大気圧以下の圧力で起こさせてもよい。いくつかの態様では、反応を2から30psia、場合により5から20psiaで実施してもよい。
。
