GN Solids Control is a world-famous company specializing in manufacturing drilling mud solid control and waste management and recycling. Its product range covers shale shaker, desander, desilter, vacuum degasser, decanter centrifuge, cutting dryer, centrifugal pump, screw pump and so on. Its products are mainly used in oil and gas drilling, civil works(like piling, TBM, HDD), and mining industry.
In the oil and gas drilling application, there is one important equipment in the solid control system, that is vacuum degasser. It is usually used after the shale shaker and before the mud cleaner. The main application of the degasser is to eliminate the gas immersed in the drilling mud, which will help restoring the mud weight, stabilizing the slurry viscosity, reducing the drilling cost, and preventing the well blow out accident. The vacuum degasser is mainly composed of vacuum tank installed on a skid base, vacuum pump, gas water separator, control panel, explosive proof motor. Its working principle is that: under the effect of the suction power from vacuum pump, negative pressure zone will be generated in the vacuum tank, and the drilling mud will enter the hollow shaft of the rotor through the suction tube under the effect of the atmospheric pressure. Then the mud will hit the windows of the hollow shaft and be sprayed to the wall of vacuum tank. Under the collision effect of the separation baffle, the mud will be separated into thin layers, and bubbles immersed in the mud will be broken up and comes out. The gas will be discharged by the vacuum pump and gas water separator to the safe zone, the mud will be discharged outside of the tank by impeller. In the whole process, the rotor will keep running at high speed under the power of main motor.
Now GN has two kinds of vacuum degasser: GNZCQ270A and GNZCQ360A, the processing capacity for these two equipment is 270m3/h and 360m3/h. Welcome to visit www.gnsolidsamerica.com
