Description
前述した酸化脱水素反応を通じたブタジエンの製造方法を実施するためのブタジエン製造装置は、C4留分、スチーム(steam)、酸素(O2)及び窒素(N2)を含む第1流30の各成分を反応器10内にそれぞれ流入させるための個別パイプラインを含むか、または反応器10と直接連結された一つのパイプラインから分岐され、前記第1流に含まれる成分が個別的に投入される複数個の個別パイプラインを含むことができる(図1を参照)。
先ず、C4留分、スチーム(steam)、酸素(O2)及び窒素(N2)を含む第1流を反応器内に流入させて酸化脱水素反応を進めさせる。
[化学式(1)]
C4H8 + 1/2O2 → C4H6 + H2O 反応式(1)
[化学式(2)]
C4H10 + O2 → C4H6 + 2H2O 反応式(2)
本発明の一実施形態において、前記反応器から得られる反応生成物は急冷段階を経ることができる。
本発明の一実施形態において、前記反応器から得られた反応生成物は、水分を取り除く脱水段階をさらに含むことができる。
本発明の一実施形態において、前記反応器から得られる反応生成物を溶媒吸収塔で吸収溶媒と接触させてブタジエンを含むC4混合物だけを吸収溶媒に選択的に吸収させ、それ以外のガス生成物(light gas)は分離/除去する。
本発明の一実施形態において、前記吸収溶媒内に含まれているブタジエンを含むC4混合物は、精製段階を経て純度高いブタジエンとして製造される。前記精製段階は、吸収溶媒を分離/回収するための溶媒回収塔23、高沸点成分を取り除くための高沸点除去塔24、溶媒精製塔25などを含む溶媒分離・回収装置、及び高純度のブタジエンを精製するためのブタジエン精製塔26の中から選択される一つ以上の装置を含むことができる(図1を参照)。
図1及び図2に示す通り、従来の場合、溶媒吸収塔21の塔頂(上段)から排出されたガスは、ガス分離段階で分離され、第2流40及び第3流50に分けられることになる。ここで、前記第2流40のガス生成物(温度11.7℃、圧力10.00KCG)をHW(ホットウォーター)を利用して加熱し、再循環させて(温度100℃、圧力9.90KCGの雰囲気で)反応器10に再投入する過程を経ることになる。
