Anderson Centrifugal Separator

Designed for

Engineered for larger pipe sizes, higher flow rates, and demanding industrial applications, the Type TL separator combines high-efficiency contaminant removal with exceptionally low pressure drop. The result is cleaner process streams, improved equipment reliability, and lower operating costs across a wide range of gas and steam services.

The TL separator is ideal when maintenance-free mechanical separation and low pressure drop are critical operating requirements.

Product configurations

The Anderson Type TL Centrifugal Separator is available in multiple configurations to meet application-specific requirements.

• TL. The standard inline model. It relies on a continuous drain setup where separated liquid drops out of the centrifugal element and must be drained immediately through a bottom connection using a separate external trap or valve.

• TLT. A smaller version of the standard TL centrifugal separator body with NPT connections.

• TLSX. Features an enlarged internal liquid storage sump/reservoir combined with specialized internal baffling or tapping options. It is designed for applications where liquid hold-up capacity is required to handle fluctuating or heavier slugging liquid loads before a dump valve or level-controlled drain is triggered.

Key points of differentiation

• Minimal maintenance. The separator uses purely mechanical centrifugal separation with no moving parts, eliminating component wear.

• Extremely low pressure drop. Unlike coalescing filters and mesh pad separators, the TL separator delivers effective liquid removal while minimizing pressure loss.

• ASME pressure vessel construction. Manufactured to ASME Section VIII, Division 1 standards for demanding industrial and process service applications.

• High separation efficiency. Effectively removes liquid and solid contaminants typically down to 10 microns.

• Wide flow operating range. Provides excellent performance across varying operating conditions and turndown ratios.

• Low-cost operation. No filter elements, cartridges, mesh pads, or routine replacement components are required.

• Versatile separation solution. The TL can operate as a standalone separator or as a first-stage knock-out vessel ahead of coalescing filters and fine mist removal equipment.

• Performs under demanding conditions. Handles higher liquid-to-gas ratios by weight compared to standard centrifugal separators.

Applications

Anderson Centrifugal Separators are commonly used to:

• Keep steam equipment clean and eliminate fouling of regulators, turbines, valves, etc.

• Remove line scale, liquids and other contaminants from process gas and air lines.

• Remove moisture from compressed air lines in plant service.

• Remove condensate and oil from compressed gases in intercooler and aftercooler service at compressor stations.

• Power generation. Gas turbine inlet protection, boiler systems, steam distribution networks, utility piping systems.

• Refining & petrochemical. Process gas cleanup, knockout service, equipment protection.

• Industrial processing. Chemical manufacturing, industrial gas systems, compressed air systems, utility services.

• Equipment protection. Upstream of compressors, dryers, analyzers, filters and coalescers; process metering stations; heat exchanger protection.

Principle of operation

The Anderson Centrifugal Separator operates using a combination of centrifugal force, impingement, and gravity separation.

1. Inlet acceleration. Gas, steam, or vapor enters the separator and is directed into a controlled rotational flow pattern.

2. Centrifugal separation. As the flow spins, denser liquid droplets and solid particles are forced outward toward the vessel wall by centrifugal force.

3. Impingement and coalescence. The separated contaminants impact internal surfaces and baffles where smaller droplets combine into larger droplets.

4. Gravity drainage. The collected liquid falls by gravity into the separator sump where it can be removed through the drain connection.

5. Clean gas exit. The cleaned gas stream exits the separator and continues downstream to compressors, turbines, dryers, filters, or process equipment.
