What is A Desander?

A desander is a drilling rig designed to separate sand from drilling fluid. It effectively removes abrasive solids that shakers cannot filter out. These are typically installed after shakers and the degasser.  The desander is crucial in reducing construction costs, minimizing environmental pollution, and enhancing efficiency. It is an essential piece of equipment for foundation construction.

Types Of Desanders

There are several types of desanders provided by desanders suppliers in China, each suited to different applications:

Hydrocyclone: Utilizes centrifugal force to separate particles from fluid, commonly used in oil and gas drilling operations.

Separator: Employs centrifugal force and gravity to separate particles, typically used in mining and mineral processing industries.

Centrifugal: A centrifugal pump creates a vortex for particle separation, frequently found in water treatment and desalination plants.

Sand Filters: Remove sand particles from water using gravity, ideal for water filtration applications.

Vibrating Screens: Vibrating motions are commonly used in aggregate industries to separate particles.

Electrostatic: Electrostatic charges are employed to separate particles and are primarily used in the coal industry.

Screen: Utilize a mesh screen to separate solid particles from drilling fluid; they are cost-effective and easy to operate.

Underflow: Rely on gravity to separate solid particles from drilling fluid, offering a relatively inexpensive and straightforward solution.

Different types are chosen based on the particle type and size, fluid flow rate and pressure, and the desired separation efficiency.

Desander Applications

Desanders can be used for various applications like:

Hydro Power: This is a crucial application area in civil engineering, involving the construction of dams, reservoirs, and power stations to harness energy from water.

Civil Engineering: Discipline that designs, constructs, and maintains infrastructure projects, including hydropower systems.

Piling Foundation: A deep foundation technique used in civil engineering to transfer building loads to a deeper, more stable soil layer.

Diaphragm Wall (D-Wall): A reinforced concrete wall constructed in deep excavations to retain soil. It is often used in foundation construction, particularly for hydropower projects.

Grab: A specialized tool used in civil engineering for excavation, particularly in constructing diaphragm walls or deep piling foundations.

Direct & Reverse Circulation Holes Piling: Methods used in piling, including those with desanders in China, involve direct circulation, where drilling fluid flows down the drill pipe and up the annulus, and reverse circulation, where the flow direction is reversed. Both techniques are essential for creating stable foundations in challenging soils.

Advantages

The following are the main advantages of using desanders in China

  • High-efficiency solids removal.
  • It’s a very compact solution.
  • Cost-effective protection against erosion damage.
  • Low operating expenses (OPEX).
  • Low maintenance due to the absence of moving parts.
  • Highly consistent performance.
  • Well-proven technology.
  • Suitable for use on floating systems.
