Description
上部の流れ15は、いくらかの軽質ガス及びナフサと共に、主として水素、アンモニア及び硫化水素を含む。その流れは、低温高圧分離機第1号(17)に供給される前に、プロセス熱交換(44)、水との接触(45)により冷却され、さらに、空気冷却(46)により冷却される。水を注入することにより、水素ガスからアンモニアの大部分を水硫化アンモニウム溶液として除去することができる。水素、硫化水素及び軽い炭化水素ガスは、流れ18として上部から除去される。流れ20は、水硫化アンモニウムを含むサワー水の流れである。流れ19は、ナフサ、灯油及びディーゼル燃料範囲の流出液を含む炭化水素の流れである。流れ18は、アミン吸収装置(21)に送られ、アミンと接触することにより、硫化水素のほとんど全量が水素に富む流れから除去される(47)。硫化水素を除去した後、ガスは、圧縮のために循環ガス圧縮機(23)へ送られる。圧縮された循環ガス(24)は、流れ25及び26に分けられる。流れ26は、さらに分けられて第1段の循環ガス供給(27)及び第1段に冷却材を供給する流れ28となる。危険なアミンは、流れ48としてアミン吸収装置から離れる。
Claims (1)
- 炭化水素原料油を水素化処理する方法であって、単一反応ループ内の多段反応域を使用し、
(a)炭化水素原料油を、水素化処理触媒を含む1つ又は複数の層を有する第1水素化処理域へ送り、前記水素化処理域を水素化処理条件に維持しておき、原料油を触媒及び水素に接触させるステップと、
(b)ステップ(a)の流出液を直接高温高圧分離機へ送り、前記流出液を高温で水素に富むストリッピングガスに接触させて、水素、炭化水素原料油の沸騰範囲を超えない温度で沸騰する炭化水素化合物、硫化水素、アンモニアを含む蒸気の流れ、並びに前記炭化水素原料油とほぼ同じ範囲で沸騰する炭化水素化合物及びディーゼル燃料の沸騰範囲で沸騰する炭化水素化合物の一部を含むボトムの流れを生成するステップと、
(c)ステップ(b)からの前記蒸気の流れを、冷却し部分的に凝縮させた後、水素化精製触媒を少なくとも1層含む高温水素ストリッパに送り、そこで水素と対向流で接触させ、その間、ステップ(b)の液体の流れを第2段反応器へ送るステップと、
(d)ステップ(c)の高温水素ストリッパからのオーバーヘッド蒸気の流れを、冷却し水と接触させた後、第1低温高圧分離機へ送り、そこで水素、硫化水素及び軽質炭化水素ガスを上部で除去し、ナフサ及び中間留分を含む液体の流れを分別に送り、それによりアンモニアの大部分及び硫化水素のいくらかを(サワー水流れが低温高圧分離機を離れるときに、そのサワー水流れ中の水硫化アンモニウムとして)除去するステップと、
(e)ステップ(c)の高温水素ストリッパからの液体の流れを、第2反応器段の水素化処理触媒層へ送り、そこで前記液体を水素の存在下で、水素化処理条件の下に触媒と接触させるステップと、
