shale shaker

GN solids control has one unit of compact design oil sludge separation system in stock for sale, the treating capacity is 1 m3/h of oil sludge, the electric motor and control system are all with explosion proof which can be used for oil industry and crude oil refinery.
The technical specification is as below:


1) Pre-mixing modular: including one premixing tank which equipped agitator on top and electric heating lines internally. This is important process to separate oil easily and increase the oil sludge flowability.
2) Coarse screening modular: one unit of mini shale shaker to separate coarse solids from the oil sludge, the discharged fluids drop into the second tank with heating lines inside the tank. A feeding pump transfer the discharged fluids from shale shaker to decanter centrifuge by adding proper chemicals before feeding.
3) Decanter centrifuge to separate fine solids from oil water fluids mixture, the mechanical cut point is 2 microns. The normal speed is 4500rpm with VFD control panel, the bowl material is made of duplex stainless steel.


4) Disc centrifuge to separate oil and water and solids, the clean oil is storaged in a buffer box and the discharged water flow to another buffer box, which can be reused in the circulation system.
5) Chemical dosing unit to add proper chemicals into the oil sludge for easier separation and reach better result.
The system is compact design which can be shipped by containers, for big project of oil sludge treatment, the client can use this system as a testing unit before order a big oil sludge treatment, we have 5m3/h, 15m3/h big oil sludge treatment system for option. Normally vacuum pump is used to transfer the oil sludge from waste pit to our system.
For more information of the oil sludge treatment system, pls contact with GN solids control.

Recently GN solids control shipped several sets of mud cleaning system to our North America client, this is for their repeat orders for vacuum truck slurry/mud cleaning system. The technical configuration of the mud cleaning system is as below:


1) Slurry collection hopper which is installed on top of the slurry treatment system, in the previous design the slurry collection hopper is laying separately, considering the area limit at client’s working site, we put the slurry collection hopper on top of the mud cleaning tank to save space. There is discharge port under the collection hopper to feed directly to the 2 units of dual deck shale shaker.


2) The coarse solids separation tank including 2 units of dual deck shale shaker and 1 unit of mud agitator. The shaker screens installed is with coarse mesh size, so that coarse solids can be separated out in this process.
3) The fine solids separation tank including 1 unit of linear motion shale shaker with fine wire mesh to separate the fine solids from the slurry, the submersible slurry pump transfer the clean mud to the mud cleaner, the desilter cone separation cut point is 25 microns. The outter protection guard is desgined for HSE purpose according to client’s feedback.


4) The clean mud discharged from mud cleaner will be transferred to dewatering centrifuge system to separate ultra fine solids up to 1 microns. The dewatering centrifuge is a big bowl big volume decanter centrifuge with VFD control panel, to increase the separation efficiency and get drier discharged solids, chemical dosing system will be used before feeding to the dewatering centrifuge.
The discharged solids will be reused for construction industry, the recovered fluids can be also used in the process. For more information of the system, pls contact with GN solids sales.

Recently one batch of drilling fluids shale shakers are ready for shipment, they are for drilling rig solids control system to separate drilling cuttings from drilling fluids. The waste drilling cuttings will be collected by screw conveyor, and transfer to drilling cuttings treatment system.
The features of GN shale shakers:


1) Shaker deck bottom made of stainless steel 304, which is fluids touch part
2) Patent C tube rubber sealing for better sealing performance and prevent the cuttings from leakage
3) 2 ea of Itavibras / Italy Oil/ US Martin brand vibrator to provide high G force up to 7.5G, whichever is suitable.
4) High grade instructure steel material mounting skid of the shale shaker to provide high strength support
5) When tandem shale shaker and triple shale shaker is required, we will make a complete skid and possum belly for the 2 units and 3 units of shale shakers


6) Our normal shale shaker is linear motion shale shaker, when 2 vibration mode is required, we will make special dual motion shale shaker to meet the client’s requirement
7) Composite material frame shaker screens installed on the shale shaker with longer working life and better separation performance.
8) If required by the client, we can provide ViST unit to increase the separation performance of the drilling fluids, the vacuum hopper is installed under the last piece screen, the vacuum unit provide vacuum so that the drilling fluids can last longer time on the screens, so the discharged cuttings is much drier, and the fluids is much clean.
Except for drilling fluids shale shaker, we also have mud cleaner, vacuum degasser, desander, desilter, decanter centrifuge, mud agitator, centrifugal pump, etc. solids control equiupments and vertical cuttings dryer, high G drying shaker, screw conveyor, vacuum pump, etc. drilling waste management equipments.

Recently GN Solids Control shipped one set of solids control system to Papua New Guinea by air. Because the project is very urgently, the client can not bear the long sea freight time, so they decide to ship it by air by a big cargo airplane. After arrived at Papua New Guinea, the user need to ship the solids control system by Helicopter because of the rough road condition there.


The technical configuration of the heli lifted solids control system is as below:
(1)1 set of mud gas separator with skid, during transportation, it is laying down for easy transportation.
(2)2 sets of linear motion shale shaker with 3 panel screens, all the shaker screens installed on the shale shaker and mud cleaner are composite material frame shaker screens for longer working life and better separation performance.


(3)1 sets of mud cleaner( desander cone, desilter cone and bottom shale shaker 3 in 1), the treating capacity is 1000gpm, the desander cone qty is 2 ea, the desilter cone qty is 12 ea. 2 sets of centrifugal pump as feeding pump to feed drilling fluids for the desander and desilter. The centrifugal pump is interchangeable with world famous brand centrifugal pump, and the wear parts- pump case and impeller is made of hard ductile iron material for longer working life.


(4)1 set of trip tank with mud agitator and mud gun
(5)1 set of mixing tank with mixing hopper, mud agitator, mud gun ,the mud agitator is vertical installed mud agitator for space saving purpose and with higher efficiency.
(6)1 set of treatment tank equipped with shale shaker, mud clener
All the equipments are installed into the heli lifting frame for safety shipment and safety lifting by the helicopter.
