HydroCat

The HydroCats are simple hydrocyclones solids/liquid separation devices, with no moving parts, designed to accelerate the settling process of solids in liquid using centrifugal force. What determines the separation size of particles in a cyclone is a function of feed pressure, cyclone diameter, exit dimensions, and the relative characteristics of the particles and liquid. Special oil/water separating hydrocyclones are also offered in this line. The incoming flow is directed into the cylindrical part of the hydrocyclone tangentially, creating a spin of the entire contents of the flow. The heavy components in the stream move outward toward the wall of the cylinder. The conical section of the cyclone causes the speed of rotation to increase throwing even smaller particles toward the wall. In solids/liquid separating hydrocyclones the solids tend to move downward to the bottom of the cyclone by gravity where they are discharged with a percentage of the incoming flow. The cleaner fluid circulating in the center forms a vortex that travels up and out of the top section of the cyclone through the vortex finder.

Features:

  • Made of abrasion resistant polyurethane, carbon steel or stainless steel
  • Ceramic or rubber liners are available for steel and stainless steel models
  • Other materials of construction are available for special chemical compatibility
  • Available in sizes from 1” to 33”
  • Single hydrocyclone models will handle flow rates from 1gpm to over 8,000gpm
  • Multiple hydrocyclones can be installed on a manifold to handle higher flow rates
  • 98 micron cuts to below 5 microns @ 50psi feed pressure on 1” polyurethane models

ParkProcess offers a full line of polyurethane and metal hydrocyclones as well as packed vessel systems. Handles flows from 1 GPM to over 1,000 GPM per cyclone depending on the series.

Pressure vessel contained cyclones

Ceramic hydrocyclones mounted in a pressure vessel for removal of sand from a pressurized system, i.e., between the wellhead and downstream equipment on a producing oil well. Flow rate is determined by the number of cyclones installed in the vessel and the size of the individual cyclones. There are 4 models of hydrocyclones available for use in the desanding vessels, with flows from 5.9 GPM to 68 GPM/each at 30 psi pressure drop. Vessel diameters typically don’t exceed 48” with a total of 151 hydrocyclones.

Oil/water separating hydrocyclones

Similar to the desander vessels, the hydrocyclones are mounted inside the pressure vessel, with each hydrocyclone rated at 7.3 GPM at 30 psi pressure drop. Fluid enters the cyclone in a tangential manner, making the fluid rotate inside the cylindrical section of the cyclone. The heavier water moves toward the wall of the cyclone while the lighter gravity oil moves toward the center. The conical shape of the bottom of the cyclone causes the rotational speed to increase further separating the two liquids. The conical section also promotes the formation of the vortex in the center that carries the lighter fluid up and out of the vortex finder, while the heavier water is discharged out the bottom.
