Centrifuges in general used for for Solids control in both situation (centrifuges high & low speed).

HICO Energy providing a prompt, efficient and reliable Solid control centrifuges, HICO provides high-speed, low speed centrifuges designed specifically to process drilling fluids to the highest environmental standards along with  delivering high fluid recovery rates and efficient solids control. Together, that adds up to a significant reduction in the operator’s total fluids cost and less waste for disposal.

Centrifuges was designed for both oilfield and industrial applications. They are especially effective in meeting the fluid-on-cuttings discharge requirements in environmentally sensitive areas. 

Our centrifuges recover as much as 95 percent of the barite in weighted drilling fluids. The barite is returned to the active mud system, while the decanting centrifuge discards the finer, lower-gravity solids. 

With the current dramatic evolution in the drilling industry mud control has become of great importance ensuring cost effectiveness.

In brief our goal is to provide the highest quality of service through a fully capable trained crew and equipment that will meet your highly esteemed company standards 

Overview: 
 

For Best Installation 

        Centrifuge stand must

• Be rated to support the weight of the centrifuge(s) while loaded and operating

  • Set the centrifuge level and at least 3 feet (~1 meter) higher than the mud tanks

  • Positioned to minimize vibrations from other rig equipment

  • Be located near solids collection site / waste pit

  • Allow a max solids discharge chute angle of 40 degrees from vertical

  • Allow for an auger if the max chute angle is exceeded

Liquid discharge piping must

• Match the liquid discharge connection on the centrifuge (see liquid discharge dimensions)

  • Not be restricted, reduced in size, or have sharp and/or numerous bends

  • Have a 10% or greater downhill slope

Feed tube inlet hose must

• Be sized to minimize head loss due to line friction (2 inch for < 100 gpm, 3 inch for ≥ 100 gpm)

  • Be supported so its weight is not loaded on the feed tube

  • Be attached to the feed tube with a flexible coupling

  • Have an auxiliary line fitting to flush out the feed tube and bowl during cleaning 
    
    
    
    
    Feed pump must

  • Be wired into centrifuge control box to allow for automatic shutoff

    • Provide adequate flow and pressure to transport mud up to the feed tube

    • Allow for variable feed rates, either by controlling pump speed or allowing bypass

    • Have an isolation valve at the tank for the pump suction line 
      Have a flush line connection with valve at the inlet 
      
      
                                                                         For Best Operation  
      
       

    • Start-up Procedure 

            Start the back drive motor – check rotation 

      • Wait 10 seconds and start the main drive motor – check rotation 

      • Give the centrifuge up to 2 minutes to achieve set speed 

      • Open the suction valve on mud tank 

      • Start pump at the minimum feed rate 

      • Bring the feed rate up slowly to desired processing rate 
        
        
        
        Shutdown Procedure 
        
        
        
               Bring the feed rate down to minimum slowly, and then shut off the feed pump

        • Close the suction valve on mud tank and open flush valve on the feed pump
        • Turn on feed pump and flush for 30 seconds, then shut the pump off
        • Flush at feed tube until diluted mud is discharged from the centrifuge; stop flush
        • Run centrifuge empty for at least 10 minutes
        • Shut off the main drive motor, back drive should still be running
          Back drive motor will shut off automatically, motor is on a time delay switch – should be adjusted to 6 minutes minimum
