Maximizing Efficiency in Solid-Liquid-Liquid Separation: GN 3 Phase Decanter Centrifuge

At GN Separation, we understand the critical role that efficient separation plays across industries. With over 10 years of experience in the separation industry, we are proud to offer advanced separation solutions, such as our GN 3 Phase Decanter Centrifuge, which is designed to handle the most complex separation challenges with ease.

What is a 3 Phase Decanter Centrifuge?

The GN 3 Phase Decanter Centrifuge is primarily designed for solid-liquid-liquid three-phase separation of materials. Unlike standard decanter centrifuges, which separate solids and liquids, the 3-phase decanter goes a step further by effectively separating two different liquid phases in addition to the solids. This makes it an essential tool in industries where the separation of oil, water, and solids is critical, such as in oil and gas, wastewater treatment, and environmental protection.

Our 3 Phase Decanter Centrifuge is engineered for continuous and smooth operation, designed to run 24/7 without interruption. Its reliable performance is driven by a robust driving system, an efficient decanter bowl, an integrated screw conveyor, and a user-friendly VFD control panel.

How Does the GN 3 Phase Decanter Centrifuge Work?

The operation of the GN 3 Phase Decanter Centrifuge is based on the principle of sedimentation. Solid particles with a higher specific gravity are subjected to the greatest centrifugal force, followed by the liquid phases of different densities. When the feed material enters the high-speed rotating drum, the centrifugal force causes the materials to separate, with solids forming the inner layer and the two immiscible liquids (such as oil and water) forming two distinct liquid layers on the outer side.

The solid phase is pushed out by the screw conveyor, while the separated liquids are extracted through respective nozzles. This process allows for highly efficient solid-liquid-liquid separation, which is ideal for various industries that require separation of oil, water, and solids.

Key Features of GN 3 Phase Decanter Centrifuge

  • Durable and High-Performance Bowl Material: The decanter bowl is made from Duplex Stainless Steel SS2205, providing superior strength and corrosion resistance for long-lasting performance.
  • Flexible Liquid Separation: The adjustable impeller allows operators to control the separation of the heavy liquid phase (e.g., water) with ease, even during operation. By adjusting the impeller, the separation line between the two liquid phases can be fine-tuned to meet specific process needs.
  • High-Quality Components: The centrifuge uses SKF or Japan NSK bearings for reliability, a planetary wheel-type gearbox for efficiency, and tungsten carbide inserts for wear protection at critical points such as the solids discharge port and material distribution nozzle.
  • Adjustable Differential Speed: The differential speed is adjustable based on operational conditions, providing flexibility to meet different material separation needs.
