THE COMBINATION OF DESANDER AND DESILTER MAY SOMETIMES BE USED TO CREATE A VERY EFFECTIVE MUD CLEANSER.

A method known as solids control is used in drilling rigs in order to separate the particles that are present in the drilling fluids. These materials are crushed by the drill bits and then transported away from the top of the hole. There are typically five steps that make up a solid control system. These stages include a mud tank, a shale shaker, a vacuum degasser, a desander, a desilter, and a centrifuge each. A shale shaker is used for the purpose of separating large particles with a diameter more than 75µm between 45µm and 74µm for desandering and 15µm and 44µm for desiltering. A high-efficiency mud cleaner is occasionally created by combining desander and desilter in a single device. A vacuum degasser is used in order to separate the air that is present in the drilling fluids whenever it is present. The degasser would function as a large agitator if there was no air present in the muck. Over the top of the mud tank is where all of these pieces of equipment are installed. Following the separation of the solids, the mud that has been cleaned would be injected back into the drilling hole. When the shale shaker was first introduced to the oil business in the early 1930s, it was the next breakthrough in solids management that came along. The technology that is used in the mining business was the source of inspiration for the shale shakers. To this day, the shale shaker continues to be the most important piece of solids management equipment that is available to the industry. The cone classifier, also known as the hydrocyclone, was yet another piece of equipment that was taken from the mining sector in the 1930s. It is the centripetal forces that are caused by the high velocity of the drilling fluid spinning in the cone that are the fundamental principle behind this device. These forces cause the larger and heavier solids to settle outward toward the cyclone wall and downward toward the underflow solids discharge. Hydrocyclones, in conjunction with the shale shaker, have developed into an essential component of the solid control system being used today. In addition to shakers and hydrocyclones, the utilization of a high-speed centrifuge has made a significant contribution to the capability of a drilling operation to lessen the quantity of mud that needs to be constructed and the diesel and barite additions that are necessary to keep the optimal proportions of low and high gravity solids. Recently, there have been advancements in solids control, one of which is the introduction of a closed loop system. This system enables improved environmental control and reduces the possibility of drilling fluids spilling out. http://kosunservices.com/solids control equipment/desander.html
