What Is an Alfa Laval LYNX Decanter?

The Alfa Laval LYNX is a horizontal solid-bowl decanter centrifuge. It continuously separates suspended solids from one or more liquid phases using centrifugal force.

The equipment contains a rotating cylindrical bowl with a conical section and an internal screw conveyor. The bowl and conveyor rotate in the same direction at different speeds.

This differential speed enables the conveyor to transport separated solids towards the solids-discharge end while the clarified liquid exits from the opposite side.

How Does the LYNX Decanter Work?

The separation process generally follows these stages:

1. The slurry enters the rotating bowl through a stationary feed tube.

2. The feed is accelerated inside the feed zone.

3. Centrifugal force moves the denser solid particles towards the bowl wall.

4. A liquid layer, commonly called the pond, forms inside the bowl.

5. The screw conveyor transports settled solids towards the conical section.

6. Dewatered solids leave through the solids-discharge openings.

7. Clarified liquid exits from the opposite end of the bowl.

Separation performance depends on feed characteristics, bowl speed, differential speed, pond depth, flow rate and chemical conditioning where applicable.

Designed for High-Solids and Abrasive Applications

Drilling mud, tunnel slurry and construction wastewater may contain sand, silt, clay and other abrasive particles. This creates demanding operating conditions for the feed zone, conveyor and solids-discharge areas.

Depending on the selected model and configuration, Alfa Laval offers wear-protection and operational features intended for such applications.

The appropriate protection level should be selected using:

• Solids concentration

• Particle size

• Particle hardness

• Feed-flow variation

• Operating hours

• Required separation result

• Expected maintenance interval

• Process-fluid characteristics

LYNX Decanter Applications

Oil and Gas Drilling

LYNX decanters can be used in drilling-fluid solids-control systems to remove fine solids and help recover usable drilling liquid.

The required configuration depends on the drilling-fluid system, density, viscosity, particle-size distribution, feed rate and desired cut point.

Barite Recovery

Certain drilling-fluid systems require controlled separation between low-gravity solids and valuable weighting material such as barite.

Successful barite recovery depends on the complete mud properties and operating conditions. A process evaluation is required before selecting the decanter and operating parameters.

Horizontal Directional Drilling

Horizontal directional drilling generates slurry containing soil, clay, sand and drilling fluid. A decanter centrifuge may be used to separate suspended solids and support liquid reuse.

Applications may include:

• Pipeline installation

• Utility crossings

• Cable installation

• Road and railway crossings

• River-crossing projects

• Underground infrastructure

Tunnel-Boring Operations

Tunnel-boring and microtunnelling projects can generate large volumes of mineral slurry. LYNX decanters may support clarification, solids dewatering and water recovery.

Feed variability and abrasive particles must be considered during configuration and wear-protection selection.

Construction-Site Wastewater

Construction water may contain suspended soil, cement particles, clay and other fine solids. A decanter can continuously separate solids where the feed and treatment objectives are suitable.

The complete treatment process may require screening, tanks, chemical conditioning or additional polishing stages.

Slop-Oil Treatment

Selected LYNX configurations may be considered for separating solids and water from oily feed streams.

Three-phase configurations may separate:

• A solid phase

• A lighter liquid phase

• A heavier liquid phase

The achievable separation depends on density differences, temperature, viscosity, emulsion stability and particle characteristics.

Industrial and Mineral Slurries

LYNX decanters may also be evaluated for selected industrial slurries, fine-particle removal and abrasive solid–liquid separation duties.

The exact LYNX model must be selected according to the application rather than the industry name alone.

Two-Phase and Three-Phase Separation

Two-Phase Separation

A two-phase decanter separates a feed into:

• Dewatered or concentrated solids

• A clarified liquid phase

This arrangement is commonly considered for drilling mud, construction slurry and wastewater containing suspended solids.

Three-Phase Separation

Selected three-phase designs can separate:

• Solids

• A light liquid phase

• A heavy liquid phase

This may be relevant to certain oily-water and slop-oil applications. Adequate density difference and suitable feed conditions are essential.

Not every LYNX model or configuration is automatically suitable for three-phase separation. Availability must be confirmed during equipment selection.

Important LYNX Features

Depending on model and configuration, the LYNX range may incorporate features for:

Wear Protection

Replaceable wear-protection components may be applied in areas exposed to abrasive feed and discharged solids.

Adjustable Operating Parameters

Bowl speed, differential speed, feed rate and pond depth may be adjusted within permitted operating limits to suit changing process conditions.

Continuous Operation

A decanter continuously receives feed and discharges separated solids and liquid, reducing reliance on batch separation.

Automated Control

Applicable automation can monitor operating parameters, alarms and protective functions. The selected control system depends on the installation and project requirements.

Maintenance Access

The equipment design provides access for inspection and service after correct isolation, shutdown and safe preparation.

Compact Installation

A decanter can provide continuous mechanical separation within a relatively compact installation compared with certain settling-based alternatives.

Information Required to Select a LYNX Decanter

Please provide:

• Industry and application

• Feed-material description

• Feed-flow rate

• Solids concentration

• Particle-size distribution

• Particle density

• Liquid density

• Fluid viscosity

• Operating temperature

• Required solids dryness

• Required liquid clarity

• Abrasiveness

• Chemical additives

• Two-phase or three-phase requirement

• Hazardous-area classification

• Operating hours

• Plant or project location

• Available utilities

• Installation-space limitations

A representative feed sample or separation trial may be necessary for applications where separation behaviour is uncertain.

LYNX Versus a Conventional Settling System

Gravity settling relies on natural density differences and may require considerable retention time and tank area. A decanter uses centrifugal force to accelerate the separation process.

Potential advantages can include:

• Continuous separation

• Compact installation

• Faster solids removal

• Reduced dependence on large settling areas

• Controlled solids discharge

• Potential liquid recovery and reuse

• Ability to handle changing solids loads

However, the decanter requires power, controls, appropriate upstream preparation and scheduled maintenance. The complete lifecycle requirements should be considered.

LYNX Versus Other Alfa Laval Decanters

Alfa Laval offers different decanter ranges for different industries and feed materials.

• LYNX: drilling, construction, abrasive slurry and selected oily-waste duties

• ALDEC: sludge thickening and dewatering in municipal and industrial wastewater

• Foodec: hygienic food and beverage applications

• Other decanter ranges may serve edible-oil, starch, ethanol, protein or specialised industrial processes

Selecting the range by application prevents a general-purpose description from being used for technically different separation duties.

Operating Factors That Affect Separation

Feed Rate

Excessive feed may reduce residence time and affect clarification or solids dryness.

Bowl Speed

Bowl speed affects centrifugal force. The permitted speed depends on the model and operating conditions.

Differential Speed

The speed difference between the bowl and conveyor affects solids transport, residence time and torque.

Pond Depth

Pond depth can influence clarification, solids dryness and separation behaviour.

Feed Temperature

Temperature may affect liquid viscosity and separation, particularly in oily-feed applications.

Particle Characteristics

Fine particles, low-density solids and emulsions can be more difficult to separate than larger, denser particles.

Operating settings must remain within the manufacturer’s specified limits.

LYNX Maintenance Considerations

A planned maintenance programme may include:

• Monitoring vibration

• Monitoring bearing temperature

• Checking for abnormal noise

• Inspecting for leakage

• Monitoring gearbox and drive condition

• Checking lubrication

• Inspecting wear-protection components

• Removing solids accumulation

• Reviewing alarms and operating trends

• Inspecting the feed and discharge zones

• Following recommended service intervals

• Maintaining critical spare parts

Only trained personnel should inspect or service a decanter after completing the prescribed shutdown, isolation and safety procedures.
