Abstract
Description
a)塩化水素を含む供給気体流Iと、酸素含有供給気体流IIを利用可能とし、
b)供給気体流I、供給気体流II、必要に応じて、塩化水素を含む循環流Ia、必要に応じて、酸素含有循環流IIa、及び循環流IIIを酸化帯域に供給し、固定床中の触媒の存在下に、塩化水素を塩素に酸化させて、塩素、未反応酸素、未反応塩化水素及び水蒸気を含む生成気体流IVを得、
c)生成気体流IVから循環流IIIを取り出し、これを酸化帯域に循環させ、生成気体流IVaを残留させる各工程を含む、塩素の製造方法により上記目的が達成されることを見出した。
及び塩化水素の酸化生成物を含む循環流6aが塩化水素酸化反応器3に給送され、同反応器中で塩化水素が触媒的に塩素に酸化される。循環流6aはジェットノズル4を用いて酸素含有流1中に導入され、循環流6と酸素含有流1とが合体して気体流5として反応器3に給送される。ここで使用される供給気体流1は、例えばP・S・A方式(Pressure Swing Adsorption)により得られる濃度94容量%の酸素(工業等級酸素)又は空気を液化して得られた酸素である。これは高圧下、例えば30バールでの操作である。塩素、未反応酸素、未反応塩化水素、及び水蒸気を含む生成気体流6が得られる。生成気体流6は循環流6aと、更に処理の行われる生成気体流6bとに分別される。生成気体流6bは急冷冷却器7に導入され、塩酸9が凝縮する。必要に応じて、水8を冷媒として急冷冷却器に給送することが可能であり、希塩酸の分流9aは冷媒として急冷冷却器に循環させることが可能である。塩化水素がほぼ完全に分離され、塩素、酸素及び水蒸気を含む流体10が急冷冷却器7から放出され、乾燥工程11に給送される。乾燥工程11では、気体流10を適する吸収剤、例えば硫酸、モレキュラーシーブ又は吸湿剤と接触させて、これにより微量の水を除去する。乾燥工程の下流域にデミスター13を配置してもよく、これにより混入した液体粒子を乾燥気体流12から除去することができる。乾燥工程11で硫酸を用いた吸収を行う場合にデミスターを用いると好ましい。乾燥し、必要に応じて液体粒子を排除した塩素と酸素を含む気体流14を蒸留工程15に給送する。蒸留工程では酸素が分離され、循環流17として塩化水素酸化反応器に循環される。塩素を含む生成物流16が得られる。不活性ガス、例えば窒素、アルゴン(純粋な酸素を用いない場合には酸素含有供給流4から得てもよい)の蓄積を回避するために、パージ流17aが用いられる。
