Latest product launches


Posted: Monday 3rd October 2011

Westgarth, the oil & gas industry water treatment specialist of Veolia Water Solutions & Technologies has recently launched the SandLiner desanding hydrocyclone for produced water treatment.

Many years of produced water system design, build and service experience have enabled VWS Westgarth to identify and improve the key factors behind desanding hydrocyclone performance. This knowledge has been applied to the SandLiner design, resulting in class leading capacity, efficiency and longevity.

The understanding of the operation and maintenance issues behind hydrocyclone technology has led to the inclusion of unique design features which make the VWS SandLiner suitable for temperatures of up to 140íC with standard seals, and any pressure class up to #2500 or API 10,000.

VWS offers testing, witnessed by the user, to verify the data used for application selection and performance guarantees.

Process Operation

The VWS SandLiner operates by introducing produced water through tangential inlets into the widest part of the conical internal cavity to create a vortex inside the liner. As the water passes through the vortex, the suspended solids are forced to the wall of the liner by centrifugal forces. The vortex flow pattern within the liner transports the separated solids along the wall to the outlet port of the liner where they flow into a catchment chamber beneath. The desanded water flows in a reverse direction, up the centre of the liner and out through the axial port at the top. Normally the sand in the catchment chamber would be intermittently discharged to a sand cleaning system while the hydrocyclones are on line, although other discharge strategies are possible.

The SandLiner complements other VWS produced water treatment technologies to enable VWS to offer the end user an integrated and optimised solution at every key process stage in the produced water treatment system.
