Introduction to Desanders
A desander serves as a critical component in mining and drilling operations. This specialized solid control equipment utilizes multiple hydrocyclones to effectively remove sand and silt particles from drilling fluids. Typically installed atop the sludge tank in the processing sequence - positioned after the shale shaker and degasser but before the desilter - desanders play a vital role in fluid purification systems. In oil and gas applications where they're commonly deployed at wellheads, these units are frequently referred to as wellhead desanders. Our wellhead desanders are available in both ASME and API compliant designs to meet various operational requirements.
Operating Principle
As fundamental solid control devices, cyclonic desanders and desilters employ centrifugal separation technology without any moving parts. The system generates powerful centrifugal forces by converting the residual hydraulic head into a high-velocity rotational flow within conical chambers. This process causes solids to migrate toward the cone walls proportionally to their mass, exiting as underflow through the bottom discharge. Simultaneously, purified liquid and fine particles return via the overflow outlet at the cone's apex.
Performance Advantages
The desander's primary operational benefit lies in its capacity to process substantial fluid volumes while maintaining exceptional separation efficiency. This capability proves particularly valuable in oil and gas applications where abrasive solids can cause accelerated equipment wear. By effectively removing these damaging particulates, our desanders significantly reduce maintenance requirements and operational downtime, thereby boosting overall productivity and cost-effectiveness.
