Feed Devices

EKF-101

FLASH GALLERY (MIXED PHASE FEED)

• Design for accommodating mixed liquid/vapor or lashing feed
• For vessel diameters greater than 900mm
• The gallery is around the perimeter of the distributor above the
  distributor loor, it is installed on a support ring in the standard design; the sidewall of the gallery has normally a polygonal form
• The feed entering tangentially against the column wall, and then the liquid collected into a pool below along the gallery while the vapor phase being disengaged

 

EKF-201

VANE TYPE FEED INLET DEVICE

• Design of curved vanes, arranged in a heavy duty housing, to reduce inlet momentum and to promote initial separation of vapor-liquid feeds
• Used for mixed phase feeds
• Suitable for installation in vertical and horizontal separators
• Inlet devices offering the following potential advantage:

1.Improve vapor distribution 2.Reduce gas speed
3.Decrease fine mist 4.Cut liquid re-entrainment 5.Lower slug momentum

EKF-301

HALF OPEN PIPE FEED DEVICE

• It is commonly used to initiate gas/liquid separation
• Allowable inlet momentum lower than that of vane type feed inlet device, normal design standard: ρm Vm2 ≤ 2100 kg/ (m.s2). Where ρm is the mean density of the mixture in the feed pipe in kg/m³ and Vm is the velocity of the mixture in the inlet nozzle in m/s
• The choice between Vane type inlet device and half open pipe is a trade- off between the required separation efficiency and the costs
• For the vessel diameter less than 0.5 m, standard design is the feed
  nozzle fitted with a half open pipe inlet device, with the opening directed downwards
• For vessel diameters over 0.5 m and inlet nozzle sizes larger than 6”, a Vane Type Feed Inlet Device is recommended
