Abstract
Description
本発明はまた、振動減少インサートを含む導管に関する。
ガス-液体混合物が中を流れ且つ一定のぬれ表面積を有する導管内、特に垂直な原材料供給導管内の振動を減少させる方法であって、導管の長さの少なくとも一部にわたって導管にインサートを設けることにより、導管の少なくとも一部のぬれ表面積を少なくとも2倍、好ましくは少なくとも6倍、さらに好ましくは少なくとも12倍に拡大する前記方法。
ここでの振動とは、導管並びに/又は導管サポート及び/若しくは配管継手への損傷を与え得る振動である。特に水平又は垂直方向における、特に大きく、急で且つ/又は不規則な振動を考える。
本発明による垂直な原材料供給導管は、ガス-液体接触塔の原材料入口に至る。このガス-液体接触塔は、ガス出口、液体出口及び原材料入口を備える。
一般に、垂直な原材料供給導管の長さは、5〜40m、好ましくは10〜30mの範囲にある。
ガス-液体接触塔の例として、ガス処理プロセスで用いられる蒸留塔又は再生器塔が挙げられる。
上述したように許容できない振動レベルを伴うガス処理プラントの垂直な原材料供給導管において、再生器入口に制限オリフィスを配置した。垂直な原材料供給導管内の振動は許容レベルまで下がったが、再生器入口のちょっと前までに高速度の流れに成長した。この高速度の流れが、入口デバイスに深刻な損傷をもたらした。
例1に記載した垂直な原材料供給導管内に、振動減少デバイスを配置し固定した。振動減少デバイスは、細長い開口管のアセンブリから構成した。導管の比に対する開口管の比は、8:1であった。ぬれ表面積は7.5倍拡大した。導管の振動は、比較例と同じ許容レベルに下がり、入口デバイスの損傷は生じなかった。
