Gas distribution inlet devices

In retrofitting situations, inlet nozzles are a common problem area. Higher gas flow volumes create poor gas distribution in crowded drums or distillation towers. This frequently results from under designed inlet distributors that allow localized high velocities and severe liquid reentrainment.

The Inlet Device is a safe and reliable inlet technology, it ensures an even distribution which is necessary in order to prevent any chance of channeling occurring through the downstream devices and to fully utilize gravity separation. The momentum of the incoming feed stream is decreased, which allows removal of any bulk liquids and solids that may be present and makes it possible to evenly distribute the gas flow over the vessel cross section. Since the fluids are not directed straight downwards onto the liquid surface, the effects of liquid re-entrainment are at a minimum.

AWS feed inlet devices provide an effective solution for vapor or gas distribution, and can solve liquid entrainment problems in many types of equipment such as:

  • Scrubbing, absorption, stripping or distillation columns
  • Evaporators
  • Knock-out drums
  • Feed inlet separators
  • 2-phase and 3-phase separators
  • Gas dehydration plants
  • Compression systems and suction drums
