Desanders are essentially reliable Management devices. Cyclonic desander and desilters use a centrifugal pressure to different solids from liquids. There aren't any rotating components. Centrifugal power is designed by turning The pinnacle of a centrifugal pump right into a superior-velocity rotating move inside of a cone.
Sure, Desanders might be custom made to satisfy the precise requirements of different programs. They are often built with numerous circulation capacities, components of development, and Command systems to suit the requirements of a particular venture.
It is a smart idea to Use a straight pipe in front of the very first cone that is thrice the pipe diameter. This enables time for the solids and liquid to remix evenly
A Desander is often a specialised equipment Utilized in the oil and gas sector for that removing of stable particles, principally sand, and other abrasive materials, within the production fluids or drilling mud.
Establishing a centrifuge pump to operate multiple pieces of apparatus is not a good idea, as doing this needs compromises in performance and prospects for incorrect operation.
Figure 2 displays a desander. The major discharge from The underside of the unit is discarded although the cleaned mud leaves in the top from the cyclone and it is discharged into the subsequent tank
Geometry, the look and positioning of various connections, and their relative dimensions are significant for successful cyclone operation and decide the Minimize-off stage (among the solids ejected with the apex and people remaining from the liquid discharge).

Desanders and desilters are utilized to get rid of solids from drilling fluid that a shale shaker is incapable of removing.

Since the centrifugal pump is faster compared to rig pumps there will almost always be a move of mud in the discharge pit to the suction pit. In this manner a hundred% of the flow will likely be taken care of. This system is shown in Figure 6
Another reason for at least three % underflow is the fact that, at decreased rates, the size of particles that may be removed is unfavorably affected, as excessive good will continue to be from the fluid.
The most crucial purpose on the electronic Manage system with the desander is to regulate the operation of the desander, together with starting off, stopping, running position monitoring, fault prognosis together with other functions from the products.
I'm a great deal obsessed with blogging and always made an effort to do exclusive factors. This Site is my initial undertaking into the earth of running desander a blog Along with the goal of connecting with other piping engineers all over the world.
The design and composition in the slurry storage tank will range based on the distinct software scenario and tools product, but generally it must fulfill the requirements of having the ability to maintain a ample amount of liquid and facilitate sand discharge and cleaning.
