The Application of desander:

KOSUN LCS series desander is the second stage solids control equipment which processes particles above 45μm in the drilling fluid, facilitating better treatment effect of the next stage equipment and decreasing its workload.

While installing a desander, please follow these general recommendations:

1. Size the desander to process 100-125% of the total mud circulation rate.

2. Keep all lines as short & straight as possible with a minimum of pipe fittings. This will reduce loss of pressure head on the feed line & minimize back-pressure on the overflow discharge line.

3. Do not reduce the diameter of the overflow line from that of the overflow discharge manifold.

4. Direct the overflow line downward into the next downstream compartment at an angle of approximately 45%. The overflow discharge line should never be installed in a vertical position, doing so may cause excessive vacuum on the discharge header and pull solids through the cyclone overflow, reducing the cyclones efficiency.

5. Keep the end of the discharge line above the surface of the mud to avoid creating a vacuum in the line.

6. Install a low equalizer line to permit backflow in to the desander section.
