Desanding Hydrocyclones

eProcess Desanding Hydrocyclone (Desander) is a fit-for-purpose solid-liquid cyclone designed to remove sand from produced water streams. This technology is most commonly installed on the outlet of a three-phase or FWKO separator. Designed primarily for water flow streams, the Desander removes sand to protect downstream oil-water separation equipment or prevent solids transport to reinjection wells. Supplied in either component or skid-based format, the Desander is available in ASME (150#-1500#) design rating.

How It Works

eProcess Desanding Hydrocyclones are pressure drop dependent, where the produced water is directed into the cyclone liner causing the solids to spin under a centrifugal force. These strong forces cause the solids and liquids to separate. Solids spiral down the cyclone to the underflow outlet, while the remaining fluids are forced in the opposite direction to the overflow. The process is a simple and effective separator, with a 2-3 second retention time, and no moving parts.

What Are the Advantages of Hydrocyclone Desander for Sale?

  • No moving parts, low maintenance, and little downtime requirements result in significant capital and operating cost savings.
  • Compact design – 10% of the size and weight of conventional filter systems provide easier mobilization.
  • Eliminates solids erosion on downstream process equipment including pipework, valves, chokes, and process vessels.
  • Provides solids removal prior to oil contamination and eliminates sludge formation and other difficult solids accumulation problems in separators and other pressure vessels.
  • Protects downstream oil-water separation equipment (i.e., deoiling hydrocyclones, CPI’s, flotation cells, and media filters).

Operations

  • Desanders are available in several sizes. Systems used in oil and gas production are typically in the 1 to 3-inch range and separate 98% of particles from 10 to 25 microns and larger.
  • Operating pressure drop requirements vary from 5 to 50 psi, with the larger desander units handling solids volumes of up to 5% and the smaller units handling up to 1% by volume.
  • Produced water streams typically contain between 100 to 1,000 ppm. At these concentrations, a desander will typically reduce solids loading to 10 to 20 ppm, removing solids up to 99% by weight.

Cleaning, Storage, and Transportation

  • Solids are typically collected into a dedicated secondary accumulator vessel. At high operating pressures, the accumulator prevents high quantities of gas flashing to the atmosphere during the purge cycle. For low-pressure applications, an atmospheric tank will suffice.
  • Solids cleaning is performed by a closed-loop cyclonic co-current process system carefully designed to ensure adequate scrubbing through turbulent flow operation.
  • To ensure the liquid content in the final batch is minimized, water is reduced by the use of a filter-bin. The solids remain and the water is collected and pumped to a slops tank. The final sand slurry is typically >90% solids by volume.
  • The collected solids are removed either by tank replacement or by vacuum truck operation.

Desander Hydrocyclone

Our desanders are the most technologically advanced hydrocyclones available on the market, and they are designed to provide the best possible performance. Under the most demanding applications, each cone will process 1000 GPM at 70 feet of head. Our desanders are engineered to produce the least amount of turbulence while maximizing tangential velocity.

Kapwell hydrocyclone desanders are designed to remove abrasive materials from drilling mud that cannot be removed by shakers or other conventional methods. Multiple desander units can be joined together to create units that can handle significantly bigger flows and solids handling capacities than they could alone.

When drilling, desanders are a set of hydrocyclones that filter out the sand and silt from the drilling fluids as they pass through them. It is common practice to put desanders on top of the mud tank, after the shale shaker and before the degasser, but before the desilter. The desander is responsible for removing abrasive materials from drilling fluids that cannot be removed by shakers. Ordinarily, the solids diameter for desander separation would be 45-74 microns.
