GN Solids America LLC’s Decanter centrifuge uses for maintain drilling fluid viscosity.

Drilling fluid containing ultrafine solids that size of 2 micron to 5 micron which has been separated by decanter centrifuge is sent to the storage tank to storage. For achieve the maintenance of the viscosity of the weighted drilling fluid is achieved by removing solids and colloidal particles that can cause high viscosity in the drilling fluid.  The barites discharged from the sediment export are sent back to drilling fluid circulating system for reuse.


The drilling fluid and barites can not be completely separated by using centrifuge during this process because that there are also large size of low density cuttings in the recovery of barites; Similarly,  the drilling fluid in the overflow contains both low density of fine solids and also very small and un-useful  barites particles.

There are use bentonites and finishing agent and also un-useful barites particles in the drilling fluid which is discharged and stored without being used. Therefore, we should add bentonites and treating agent to drilling fluid when adding the fresh liquid to the drilling fluid.

GNLW series decanter centrifuge line offer bowl size of 9 inches, 14 inches, 18 inches and 22 inches. It can meet the demand of different treating capacity.  Besides the bowl size, it also offers the various speed adjustment and fixed speed to meet the demand of mud treating for the drilling mud. The series number is GNLW363VFD, 453VFD, 553 VFD, 223, 363 and 452.  GN Solids America LLC has a large warehouse get to 30, 000 sq. feet. GN Solids America helps to keep many decanter centrifuges are available in Houston. GN Solids America is providing rental services for these centrifuges and the some other solids control and going waste management systems. We have full after-sale service tech on stand-by status to service our machinery in timely matter.

GN Oil Slurry Treating Unit

GN Solids Control is especially good at providing tailored solids control and waste management treating systems. Now GN Solids Control has provided equipment for customers from over seventy countries. Every year, over hundreds of customized solids and liquid separation equipment are provided.
Just take the oil slurry treating unit for an example, GN oil slurry treating equipment is mainly used to treat high density and high viscosity sludge like refinery plant oil sludge, oil tank sludge etc. Here is one inquiry we months ago for one Canada customer. Inclined Plate Clarifier
We as a company are in a process to submit an offer economic to the customer. Basically we have the need to manage waste generated in a heavy crude treatment plant, on the one hand we want to make the separation of solids in petrol sands approximately 660 Bls / D. We must also manage the production water and carry out the separation of the crude present in it, we should manage approximately 7200 Bls / D.
As mentioned previously, we are in the process of presenting an offer economic and I wanted to know the approximate cost of these equipment, and that can handle these proportions of waste.
I was reviewing the general brochure that you sent me and I thought of a system in series or parallel of equipment: Inclined Plate Clarifier and Oil Water Separator. I would like to know if it is possible to use it from this way, if you know of a project similar to the one I am mentioning, or if you can give me a better option for this.
According to the data that I was reviewing and the Data Sheet’s of the equipment I think it would be useful for me: Inclined Plate Clarifier 35 m3 / h and Oil Water Separator 98 m3 / h.

Based on customer’s above demands, we provided one set of oil sludge treating unit.
