Anderson Centrifugal Separator with Coalescing Mesh

CLL · CLI · CLU

The Anderson® Centrifugal Separator with Coalescing Mesh is a high-efficiency, dual-stage mechanical separation system designed to remove liquid aerosols, entrained mist, condensate, and solid contaminants from air, gas, steam, and vapor streams. Combining a coalescing mesh pad with Anderson’s proven centrifugal separation technology, the CL Series delivers exceptional contaminant removal efficiency while maintaining low pressure drop and minimal maintenance requirements.

LIVE 3D SECTION

Designed for

 

CL Series is specifically engineered to capture and remove fine aerosols and mist particles that can negatively impact process efficiency, equipment reliability, and product quality. The result is cleaner, drier process gas and enhanced protection for critical downstream equipment. With no disposable filter cartridges and a rugged ASME pressure vessel design, the CL Series provides a reliable and cost-effective solution for demanding industrial applications.

 

The CL Series is particularly effective when contaminant particles are too small for traditional centrifugal, vane, or cyclone separators to remove efficiently.

 

Product configurations

 

The Anderson CL Series is available in multiple configurations to accommodate a wide range of process requirements, installation constraints, and flow conditions.

 

  • CLL – horizontal or vertical downflow. Available in horizontal or vertical downflow arrangements, the CLL combines high-efficiency aerosol removal with substantial liquid handling capability.

  • CLI – inline. Engineered for direct integration into pipeline systems where space is limited and simplified installation is preferred.

  • CLU – vertical upflow. A vertical upflow design commonly specified for applications requiring vertical installation or where system layouts favor upward gas flow patterns.

 

Key points of differentiation

 

  • Dual-stage separation technology. Combines coalescing mesh technology with centrifugal scrubbing action, providing significantly greater efficiency than standalone centrifugal, vane, or cyclone separators.

  • Superior fine mist removal. Designed to remove 99% of liquid and solid contaminants 4 microns and larger, the CL Series delivers enhanced protection against aerosols that often pass through conventional mechanical separators.

  • Low pressure drop performance. Achieves high separation efficiency without the pressure loss commonly associated with disposable filter elements and cartridge-style filtration systems.

  • Lower operating costs. Eliminates recurring cartridge replacement costs while maintaining long service life.

  • Durability in demanding environments. Standard 316 stainless steel coalescing mesh and 316L stainless steel Hi-eF™ centrifugal elements provide excellent durability and corrosion resistance.

  • ASME pressure vessel construction. Manufactured to ASME Section VIII, Division 1 standards, the CL Series is suitable for critical gas, steam, and process applications.

  • Easy inspection and maintenance. Accessible internals simplify routine inspection and cleaning, reducing maintenance downtime and improving long-term operating reliability.

 

Applications

 

The Anderson Centrifugal Separator with Coalescing Mesh is widely used across industries where fine aerosol removal and equipment protection are critical.

 

  • Natural gas processing. Gas gathering systems, transmission pipelines, fuel gas conditioning, compressor stations, gas dehydration systems.

  • Refining & petrochemical. Process gas cleanup, reactor protection, vapor recovery systems, hydrocarbon processing operations.

  • Chemical processing. Feed gas conditioning, catalyst protection, process gas purification.

  • Power generation. Gas turbine fuel systems, combustion support systems, HRSG applications, steam distribution networks.

  • Industrial facilities. Compressed air systems, plant utility services, manufacturing processes, industrial gas applications.

  • Equipment protection. Compressor suction and discharge lines, fuel gas lines to engines, molecular sieve systems, desiccant beds, dryers and scrubbers, process analyzers and instrumentation.

 

Principle of operation

 

The Anderson CL Series utilizes a two-stage mechanical separation process that combines coalescing technology with centrifugal scrubbing to achieve exceptional contaminant removal performance.

 

  1. Coalescing. Fine liquid aerosols and mist droplets impact the mesh surfaces and combine into larger droplets through the coalescence process.

  2. Centrifugal force. The larger coalesced droplets and solid contaminants are subjected to centrifugal force, causing them to move outward from the gas stream and separate from the flow.

  3. Gravity collection and drainage. Separated liquids and solids collect in the vessel sump, where they are safely removed through the drainage system.

  4. Clean gas discharge. The cleaned gas exits the separator with significantly reduced liquid and solid contamination.

 

This dual-stage design effectively bridges the gap between traditional mechanical separators and cartridge-based coalescing filters, delivering high-efficiency separation without the ongoing maintenance and replacement costs associated with disposable filter media.
