Centrifuge for Solids Control and Waste Management

Leave a reply

In oil and gas industry for solids control equipment, the centrifuges are more and more used for separating out the fine and extra fine particles from the drilling mud system. In fact, they are taking over the former position of hydrocyclones like the desander cones and desiter cones.

Depending on the applications, the centrifuges could be divided as following items. And GN Solids Control, as the leading centrifuge manufacturer in China oil and gas industry, GN has a complete series of centrifuges, and such centrifuges cover all applications needed in the solids control and waste management systems as below:

1. solids control centrifuge. This is the centrifuge used in solids control system, as the fourth step for separate out the solids from the drilling mud. Normally, there are 2 centrifuges used in a solids control system for a large horse power system, one is for separating the valuable drilling material barite, which is expensive in price and could be re-used in future projects, the other is for separating out the particles which are too fine for the desilter cones. In most cases, GN clients use GNLW452 for barite recovery and GNLW363-VFD for extra fine particles in solids control system.

2. waste management centrifuges, for further treatment of the drilling liquid, the dewatering centrifuge. When the drilling fluid is used and reused for several times, there are extra fine particles in the drilling fluid are too fine for the centrifuge itself to get them out. So the end users need to add chemicals to merge them to be bigger, big enough for the centrifuges. In this case, GNLW363CG-VFD is recommended as the dewatering unit. And also, GN has dewatering unit available.

3. waste management centrifuge for further treatment of the solids discharged from the solids control system. When the solids are collected from the solids control system, they are not dry enough and couldn’t be discharged directly. So for the water based mud, there’s a drying shaker of High-G force and for the oil based mud, there’s a vertical cuttings dryer before the decanter centrifuge. GNLW363CG-VFD of high speed decanter centrifuge is ideal for this application. And GN also has GNZS594HGE-LD drying shaker and GNCD930CD Vertical cuttings dryer for the complete system.

Recently, GN Solids America LLC got many inquires on decanter centrifuge, the following shows the rough separating process:
Our client will set up a primary jaw crusher to refuse the ore to minus 1.5 inches, then they will feed all the feldespar material -1.5 inch to a horizontal impactor on a closed circuit with a screen to have the material passing 4 mesh here with help of water. From here GN come in with our equipment, at this point our client need a product for a costumer -4 mesh x + 14 mesh, all this size will leave the line as a product.
The rest of the run of the feldespar -14 mesh will have to be desilted on GN secondary equipment and be cut to -250 mesh or -270 mesh ( 14x-270) this is another product and will leave the line and be stacked also by conveyor means.
The rest which is -270 mesh is considered Kaolin clay. This will be treated in GN machines like we do with mud cyclone it centrifuge it and dry it.
GN decanter centrifuge can help to separate the solids that larger than 2~5 microns, so all the solids that below -270 mesh can be separate out. And for the first phase separation, GN can use opening mesh shaker screens to separate those large particles, while for the smaller solids, GN can use desilter cyclones to separated them out.
