GN Solids America’s shale shaker screen comply API RP 13C standard from API. The America Petroleum Institute screen labeling practice, API RP 13C standard:

API RP 13C uses particles to measure the coarsest particle that passes through the screen, resulting in a measured value of D100.
Historically API RP 13E’s D50 was considered the primary cut-point of the screen. Currently, API RP 13C uses D100 to compare two different screens.
Separation curves show that the D100 value is always coarser than the D50 value.

As we mention before, shale shaker screen is the wear and tear parts of shale shakers. GN Solids America LLC produce steel frame and composite frame. The frame was made with 2 or 3-layer stainless steel wire cloth. The wire cloth can be combined with the frame with metal rubber lining, or directly bonded on the frame.

GN Mini Centrifuge
The following shows one client who is interested in our 9 inch centrifuge GNLW223.
We are interested in the decanter centrifuge GNLW223. The intention is to separate finer partials from dewatering fluid. This fluid should contain partials less than 75 micros. 2-5 micron will ideal. The flow capacity is about 30 to 50 GPM.
For planning and field connection, please provide details on all connections, overall size, any installation requirements.
Is there any restraint at the water discharge port and muck discharge port? In the other words, how to keep the slurry in the bowl long enough before it gets discharged?
a. The differential speed between the rotating bowl and screw propeller will determine the time of the slurry inside the centrifuge. Differential speed is 35:1, you can change the speed by using different pulley and belt. Generally speaking, the higher of the running speed of the screw propeller, the shorter of those slurry will be stay inside. Working principle is as following shows.
Is a tank needed to collect discharge water under the centrifuge? Can the 3” discharge port be connected to a 3” pipe and deliver water ~100’ away under a certain pressure?
From theory, it will make sense. Actually, all the water (or fluids) will be collected by a tank first, and then GN use another pump to transfer it to somewhere.
However, when you treat different fluids with different density and viscosity, the separating parameters are not the same, all the above parameters are just for reference. GN Solids America can send our engineers for after sales service if you need. GN mini shaker are also used to separate the solids before feeding into decanter centrifuge.

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.
