Desanding Hydrocyclones

Desanding Hydrocyclones

Peerless Separation & Filtration

Desanding Hydrocyclones are pressure-driven cyclonic separators that utilize a certain pressure drop across the unit to force the separation of the solids from the bulk phase produced water or condensate. The feed stream, containing high amount of solids/ sand, enters the hydrocyclone through a tangential inlet under a pressurized condition. This is where it is forced into a spiral motion by the hydrocyclone’s internal profile. The internal conic shape of the liner causes the spinning/ swirling effect to accelerate (which effectively creates) high centrifugal forces, causing the denser solid particles to move to the outer wall of the hydrocyclone liner, while the lighter phase water or condensate is concentrated to the central core of the liner.

Solids continue to spiral down along the outer wall of the hydrocyclone to the bottom exit which is typically collected in an accumulator (could be integrated or a separate unit) for periodic disposal. The “desanded” water in the central core section reverses direction and is forced out through the central vortex towards the top of the Hydrocyclone.

Hydrocyclones are effectively centrifugal separators that rely on the differential density between the solids particle and the water to allow separation.

The efficiency of the separation is governed by four main factors:

  • Solid Particle Size
  • Differential Density
  • Viscosity of the Bulk Fluid
  • Gravity (or Centrifugal Force)

Deoiling Hydrocyclones

Deoiling Hydrocyclones

Peerless Separation & Filtration

The horizontal deoiling hydrocyclone vessel with liners is designed to reduce the oil content of the incoming produced water prior to entering an optional degasser vessel. The horizontal arrangement allows easy access to the liners for inspection, installation, and replacement.

Liquid/liquid cyclones – On entering the cyclone tangentially, the fluid begins to spin. This creates a radial force that directs the heavier phase towards the edges of the cyclone and then out of the cyclone underflow owing to differential pressure. The less dense phase is concentrated in the centre of the cyclone before passing out of the cyclone overflow, again due to differential pressure.

Hydrocyclones are effectively centrifugal separators that rely on the differential density between the oil droplet and the water to allow separation. The efficiency of the separation is governed by five main factors:

  • Droplet/Particle Size
  • Differential Density
  • Viscosity of the Bulk Fluid
  • Gravity (or Centrifugal Force)
  • Distance

The reject from the hydrocyclone comes out in a counter current flow as a reverse spinning vortex. For an oil droplet to be removed it must make its way from the bulk fluid into the central core. The less distance the droplet must travel to get to this central core the higher the efficiency.

APPLICATIONS

Deoiler Hydrocyclones were developed for the offshore oil industry in the 1980s and rapidly became established as standard equipment used for recovery of oil from Produced Water streams in both onshore and offshore applications.

Walnut Shell Filters

Walnut Shell Filters

Peerless Separation & Filtration

Nutshell filters are a type of tertiary treatment and are designed to provide an adsorption duty to low concentrations of free oil present as fine droplets.

They are therefore ideal for use as polishing units to be installed downstream of a hydrocyclone or flotation package prior to disposal or reinjection. Typically, they have a feed concentration limit of 50 mg/l for both oil and solids and a maximum solids mean size of 5 microns. Nutshell filters are most found in onshore installations due to their size and weight and the requirement for large ancillary items such as backwash storage tanks and recirculation pumps. They are however very simple systems with inexpensive media and their low requirement for operator intervention has made them ideal for use at onshore fields at remote locations.

Crushed nutshells constituting the packed bed within the vessels form an intricate network of tiny channels forcing the water to take an arduous flow path from the top to the bottom of the vessel. Multi-grade nutshell offers excellent oil coalescing and holding capacities and solids are removed by simply becoming trapped within the pore structure of the bed. As increasing quantities of oil are adsorbed by the nutshell surface capillaries, the fine solids removal capacity also increases. The filtered water is collected within the base of the vessel by a wedge-wire lateral system which routes the water out of the vessel. Nutshell filters provide a large adsorption area to allow easy adhesion of oil to the nutshell’s surface due to the presence of microscopic capillaries within the structure. Adsorption occurs due to the specific nature of the interaction between the oil content of the produced water and the surface of the crushed nutshells.

Adsorption occurs at the surface of the nutshells and is not to be confused with absorption which implies diffusion into the media to form a solution.

The media also provides effective solids retaining capacity and the presence of oil acts to increase the solids removal efficiency. The ability of the multi-grade nutshell to provide large holding capacities gives long run times and reduced volumes of backwash water.

Solids are removed from the down flow of produced water within the bed where they are trapped within the porous structure of the densely packed crushed nutshell media.

Media Filters

The liquid containing solids and Hydrocarbons passes through a granular particulate media which retains these particles and only allows the passing of water into the outlet.

The Walnut Shell Filter performs at its best in produced water applications where outlet requirements are very strict. Not only does the Walnut shell can act as a fine filter, but the shells themselves coalesce the oil droplets within the media allowing greater efficiency in the removal.

The walnut shells are also very light and have a high modulus of elasticity so complete replacement of the media is limited.

Backwashing

Oil does not directly absorb into the media and oil remains entrapped. Backwashing is required to remove this oil.

An automated activity regenerates the media. The backwash is determined by either:

  • Pressure drop
  • Monitoring of outlet water quality
  • Pre-set time

Associated with the accumulation of oil and solids within the packed bed is an increase in pressure drop through the filters. To resolve this, the automatic backwashing cycle is programmed to activate on a timed basis, however this can be overridden by high pressure drop. A pressure drop signal is provided to the control system by a Differential Pressure Transmitter located on each of the fine filter vessels.

The backwashing program is timed such that all filters are backwashed once every 24 hours, however in the event of high pressure drop across the package each filter will be backwashed in sequence. During backwash, fluids are rerouted upwards through the vessel to fluidise the bed.

All effluent scrubbed from the surface of the media is routed to a discharge line for treatment and disposal. Individual vessels are isolated by actuated isolation valves located at the inlets and outlets of the vessels. All rerouting of incoming fluids between the inlet line to the vessel outlet is performed by means of actuated isolation valves located on the respective lines.

This can be recycled back to the upstream produced water treatment system.

FEATURES & BENEFITS

  • Fluidisation of the bed – the recirculation pump is in operation causing the media to fluidise within the flooded vessel and dislodge trapped solids and discharge to the scrubber for removal of trapped oil.
  • Discharge of the backwash effluent – the vessel receives inlet produced water in reverse backwashing flow to dislodge and discharges to a point upstream for treatment.
  • Media settling – the vessel is isolated, and the media is left for a short period to settle.
  • Setting the bed – the vessel is switched to forward flow to pack the bed down with the discharge routed upstream for treatment.
  • Filtration – the vessel is placed back into normal filtration operation.
