Coalesceur AquaSep® XS

Introduction

Pall’s new AquaSep XS liquid/liquid coalescer system is a lower cost solution to separate emulsions versus competitive cartridge coalescers and other traditional methods. Its cost effectiveness is due to the ability of each coalescer element to process a higher flow while still providing superior effluent quality. For existing cartridge coalescer systems, the AquaSep XS element provides superior removal of slugs of liquid contaminant thereby making it a more reliable solution than competitive offerings. See Figures 1, 2, and 3.

Description

The AquaSep XS system is a multiple-stage system starting with filtration to remove particulate matter, followed by either a one-stage or two-stage integrated coalescer stack to separate the two liquid phases. AquaSep XS coalescers will remove free water to a level as low as 15 ppmv1 and be effective over a wide range of conditions such as inlet liquid contaminant concentration as high as 10% and interfacial tension less than 20 dyne/cm.

The AquaSep XS coalescer system is available in two different housing configurations. Les deux configurations commencent par une étape de filtration permettant d’éliminer les contaminants solides.

 
Condition de traitement Produit recommandé
The dispersed phase fluid is aqueous and the IFT> 3 dyne/cm AquaSep XS coalescer/separator stack in a vertical housing
The dispersed phase fluid is aqueous and the IFT< 3 dyne/cm AquaSep XS coalescer in a horizontal housing without separator
The dispersed phase fluid is oil and the continuous phase fluid is aqueous
 

AquaSep XS Coalescer/Separator Stack—Vertical Housing Configuration

The liquid/liquid mixture enters the coalescing element and flows inside-to-outside. Small liquid droplets suspended in the continuous phase come together, or coalesce, as the mixture moves through the coalescer medium.

La phase continue et les grosses gouttelettes de phase dispersée s’écoulent vers le séparateur situé juste en dessous du coalesceur. The flow is outside-to-inside. Le séparateur est hydrophobe pour empêcher la phase aqueuse d’entrer dans la cartouche.. Seul le fluide non aqueux de la phase continue pénètre dans le séparateur. Les deux liquides sont extraits par des systèmes de drainage différents.


AquaSep XS Coalescer—Horizontal Housing Configuration

In a horizontal housing, the liquid/liquid mixture enters the coalescing element and flows inside-to-outside, small liquid dispersed phase droplets suspended in the continuous phase come together, or coalesce, as the mixture moves through the AquaSep XS coalescer. Les grosses gouttelettes de la phase dispersée sont séparées par gravité dans le corps de filtre horizontal puis sont éliminées. The size of the housing is a function of the flow rate, IFT, viscosity, and specific gravity of the liquids.
