Liquid distributors

EKD-101/EKD-102

PAN TYPE (OPEN ORIFICE)

•  Design for installation as onepiece assembly, diameter up to 1200mm
•  Liquid level balanced by orifices located in the pan bottom
•  Vapor low through circular gasriser, as wellas via the gap between the pan and the vessel wall
•  Maximum operation turndownratioat 2:1
•  For clean liquid service
•  Not suitable forservingas a liquid redistributor

PAN TYPE (DRIP TUBE)

•  Alternative design to the typeEKD-101, diameterup to 1000mm
•  Liquid level balanced by orifices located in drip tubes fitted to the pan
•  Vapor low through circular gasriser, as well as via the peripheral section between the pan and the vessel wall
•  Standard design for an operation turndown ratioat 2:1, and with an optimized design a high turndown ratio at 4:1 by using multiple level of orifices in the drip tubes
•  Low to moderate fouling tendency

 

EKD-201

CHIMNEY TRAY (OPEN ORIFICE)

• Available for any diameter, custom designed chimney arrangement for various application requirements of liquid distribution and pressure drop
•  Liquid low through orifices located on the traydeck, vapor low through chimneys
•  Standard operation turndown ratioat 2:1
•  Standard design for cleanliquid service;lower fouling tendency when using larger bottom orifices for higher liquid low rate
•  This distributoris suitable forliquid redistribution

 

EKD-202

CHIMNEY TRAY (DRIP TUBE)

•  Alternative design to the type of EKD-201, availablefor any diameter
•  Liquid low through orifices located in drip tubes fitted to the tray deck, vapor low through chimneys
•  Standard operation turndown ratio at 2:1,and high turndown ratio at
• 4:1 available by using multiple level of orifices in the drip tubes
•  Low and moderate fouling tendency
•  This distributoris suitable forliquid redistribution

 

EKD-301/302

TROUGH TYPE (OPEN ORIFICE)

• Design for accurate liquid distribution, diameter greater than 900mm
• Liquid metering through orifices located on the bottom of the troughs
• Vapor passage supplied by the gap between the troughs
• Liquid fed to theupper central parting box, and then into the troughs below; optional design: a central trough (same level as lateral troughs) to provide structural support and liquid equalization between troughs
• Maximum turndown ratio at 2:1
• For clean liquid service (limited fouling resistance)

TROUGH TYPE (DRIP TUBE)

•  Alternative design to the type EKD-301, diameter greater than 900mm
•  Liquid low through orifices located in drip tubes fitted to the troughs, vapor through spaces between troughs
•  Standard operation turndown ratio at 2:1,higher turndown ratio at 4:1 achievable by using multiple level of orifices in the drip tubes
•  For low to moderate fouling services

 

 

EKD-303/304

TROUGH TYPE (GUIDED LATERAL TUBE/ PLATE)

• Diameter greater than 900mm, possibly up to 4000mm
• Liquid low through orifices located in the trough sidewalls, vapor through the gap between the troughs
• Guided drip tubes fitted to the exterior of the troughs conducting the liquid from drip points to decrease entrainment and to eliminate liquid misdistribution; overlow holes provided at each guided tube
• Alternative liquid conduction design with large holes in the trough sidewalls accompanied by thin plate discharge system will provide a high fouling resistance
• Standard turndown ration at 2:1, ratio up to 10:1 is achievable with this configuration

 

 

EKD-401/402

PIPE TYPE (OPEN ORIFICE/SPRAY NOZZLE)

• Design with inlet basic pipe and lateral ones
• Liquid low through orifices located in the wall of lateral pipes, alternative design via spray nozzles
• Spray nozzle design for complete liquid coverage and wetting of the bed
• Maximum turndown ratio at 2:1
• Standard design for clean liquid service
