KOSUN oilfield drilling mud decanter centrifuge can meet with different requirements of mud treatment under various drilling condition, that can do sedimentation and separation for particles more than 2 um. After treatment, the mud can achieve ideal viscosity and proportion, results in better recycling, high efficiency, saving and environment protection.

The mud separation process between solid phase and liquid phase is completed in the roller. Decanter centrifuge separation principle is to use high-speed rotating roller driven into the mud in the high speed rotating drum, mud was dumped into the wall to form a liquid circle, solid phased particles of liquid ring get greater than its own gravity for undreds or even thousands of times the effect of centrifugal force, will overcome the resistance of the slurry viscosity to the roller on the inner wall of rapid subsidence formed solid layer, liquid forming liquid layer.

In order to fully understand how a decanter centrifuge operates, we must first define what a centrifuge does. In many industrial jobs, solid material often mixes with liquids, contaminating water supplies or turning mud into sludge. A decanting centrifuge is useful in that it separates solids and liquids, and has become an essential component of water waste facilities and the chemical, oil, and food processing industries. Moreover, without a centrifuge, many of these companies would become so inefficient they could not function.

KOSUN is capable of providing customers with such three series as oil & gas drilling solids control equipment, decanter centrifuges, shale shaker, mud gun, mud agitator, vacuum degasser, jet mud mixer, mud cleaner, desander, desilter and drilling waste treatment equipment(DWM), including 25 categories of products, which are extensively used in oil & gas drilling and workover, coalbed methane drilling, shale gas drilling, water well, geothermal well drilling, trenchless horizontal directional crossing projects, mine gravel staged treatment, tailings treatment, rive dredging works, industrial wastewater treatment, environmentally friendly sewage treatment, waste oil recovery, purification treatment, etc.

FeaturesGN Mud Gas Separator is designed for continued drilling in underbalanced conditions where dramatic pressure surgesare normal. The GN Mud Gas Separator is manufacturing according to API and ISO Standard.In dangerous “kick” conditions, the Mud Gas Separator allows operators to circulate the drilling fluid by removing largepockets of gas. The gas cut mud enters the flow line of the unit, where it hits a series of baffle plates. These baffle platesprovide surface area for the dispersion of the gas cut mud. The mud is routed to solids control equipment for further pro-cessing while the separated gas travels to the flare line at the top of the unit to be vented at a safe distance from the rigand rig personnel.

GN solids control designs and manufactures various types of tank including mud tank, wa- ter tank, oil tank, etc. GN solid control mud tanks are usually used to install solids control equipment, storage mud, mixing mud, etc. It meets utility request of the drilling solid con- trol system, mud plant and solid-liquid sepa- ration system.

Hoppers, mud guns, desanders, desilters,degassers, and triplex pumps requiring supercharging all have one thing in common: they require 76–80 feet of inlet head to operate as designed. Exceptions do exist, and the equipment manufacturer should be consulted. This simplifies the job of sizing centrifugal pumps. Since most applications in drilling systems require 80 feet of head at the inlet of the equipment, knowledge of volume needed by each piece of equipment is required. Following are standard flow rates when equipment has an 80-foot inlet head:

Take, for example, a contractor who wishes to operate a two-cone desander equipped with 10-inch cones and anticipates the maximum mud weight to be 16 lb/gal. The pump is mounted on the same deck as the desander and is 150 feet away. The inlet to the desander is 10 feet above the deck. The supply tank minimum liquid surface level is 8 feet above the pump centerline. Remember that two 10-inch cones will flow 1000 gpm and that the desander requires 80 feet of inlet head:

80 feet required by desander + 10 feet of discharge elevation − 8 feet of positive suction elevation + ? discharge friction loss   + ? suction friction losses    = TDH required at discharge of centrifugal pump.

Discharge elevation above pump centerline is 10 feet; supply tank liquid surface level is 8 feet above the pump centerline; and the required desander inlet head is 80 feet. Therefore, 80 = 10 – 8 +22.5 + 2.24 = 106.74 TDH required. Knowing the flow rate of 1000 gpm and TDH required at the pump to be 107 feet, an individual can begin the pump selection process.

Centrifugals must be sized using maximum values anticipated, to ensure that they can perform without cavitation and that the driver is adequately sized. If there is a possibility that the contractor would add a third cone and flow at 1500 gpm, the pump must be sized to handle up to 1500 gpm (this would also affect line velocities and friction losses). Motors must be sized for maximum mud weight. For this example, assume 1000 gpm to be the maximum flow rate and 16 lb/gal mud to be maximum mud weight. A pump to produce 1000 gpm at 107 feet TDH is required. This operating point is marked on attached curves (see Figure 1. – 6.).

5×4×14: Located at the end of the curve. NPSHR is very high. If this pump is used, cavitation is likely due to insufficient NPSHA. Even given sufficient NPSHA, if additional cones are added, mud temperatures rise, or if the desander cone wears, the pump could not handle the increased volume required. This would be an unacceptable sizing choice.

Knowing the SG of the fluid is necessary to determine the hp required. Maximum mud weight in this example is 16 lb/gal. To determine SG, use the following formula:
