Remove solids from fluid streams with a range of properties

The MOZLEY Desanding Hydrocyclone solids-water separator is a versatile technology based on an optimized internal geometry that can accommodate a range of solid types and concentrations, fluid rates, pressures, and temperatures. This makes MOZLEY separators well-suited for the unique applications found in the oil and gas industry, including treatment of produced water, aquifer water, and deballast water; hydrocarbon desanding; and other sand cleaning operations.

Manufactured from abrasion-resistant ceramics that provide enhanced wear resistance and longer life, MOZLEY separators are designed to increase solids removal and reduce downstream issues while still allowing full production.

MOZLEY Desanding Hydrocyclone solids-water separators

Handle high flow rates with a compact system

Many hydrocyclones can be packed into a single vessel, resulting in a high unit flow rate. There are no moving parts in a vessel and operate continuously with minimum supervision and maintenance. Sand separation can be a fully automated with continuous or batch discharge of solids, with or without sand accumulation.

Separation of 98% of particles from 3 to 108 um

Flow rates from 25 to 100,000 bbl/d [3 to 11,924 m3/d] of water

Pressure drop of 10 psi [0.07 MPa] from inlet to overflow outlet

Customizable solutions for your solids challenges

The performance of a hydrocyclone depends on the pressure drop across the inlet and overflow outlet and the volume split to underflow. In general, a higher pressure drop yields a higher capacity and sharper separation.

Thus, the diameter of a hydrocyclone influences the size of solids removed. MOZLEY Desanding Hydrocyclone separators are available with individual hydrocyclone sizes ranging from 0.5 in to 30 in, with 2-in or 3-in ceramic desanding hydrocyclones standard for most applications.

The larger diameter, single-liner units offer high flow rates, but are not as efficient at removing smaller solids as narrower-diameter units that have multiple liners in a single vessel. Because of this, the diameter of hydrocyclone is selected based on the size of solids targeted for removal, with further optimization achieved by tailoring aspects such as inlet and outlet diameter. Construction material can also be matched to the solids expected in the system, for instance polyurethane for low-temperature applications, or extremely abrasion-resistant ceramic materials to address highly erosive solids.

Matching the most suitable hydrocyclone geometry with construction materials that can best address the characteristics of the process fluid and suspended solids creates a customized separation solution for most applications that will deliver reliability and efficiency over alternatives.
