mud cleaner

This week GN solids control finished production of vacuum degasser and mud cleaner for clients in Middle East.


We have 3 types of degasser for oil & gas drilling industry, vacuum degasser, centrifugal degasser, mud gas separator. The mud gas separator is installed before the solids control system trip tank, to separate the hazardous gas from the drilling fluids and prevent it from kick off. The vacuum degasser and centrifugal degasser is used after shale shaker and behind desander, desilter or mud cleaner, the function is to separate the gas from the gas cut mud and protect the next process equipments like centrifugal pump, and keep the balance of the drilling fluids, their function is same, just vacuum pump is installed horizontally on the tank top, the centrifugal degasser is vertically installed in the mud tank , it can save space on the mud tank.


The mud cleaner produced by GN solids control is a combination of desander cone, desilter cone and bottom shale shaker. With different qty of hydrocylones, there are different treating capacity for option. The desander cone, desilter cone material are 100% polyurethane which is wear resistance material. The bottom shale shaker equipped with 4 panel shaker screens, with composite material frame for longer working life. Centrifugal pump #1feed the mud from degasser tank to desander cone, the clean fluids dropped into the desander compartment, the solids are separated out and drop down to bottom shale shaker, the useful fluids will be collected and the drier solids are separated out from shaker screens. Centrifugal pump #2 feed the mud from desander compartment to desilter cone, the clean fluids dropped into desilter compartment, which is clean fluids can be reused to prepare for new fluids or can be reused directly.
For more information about vacuum degasser and mud cleaner, 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.

As one of the most professional HDD mud recycling system in China, we can design and produce mud cleaning & mixing unit with different treating capacity as 200gpm, 350gpm, 400 gpm, 500gpm, 600gpm, 800gpm, 1000gpm, 1500gpm, also we can provide customized design mud recycling system as per client’s requirement. Below is the 200gpm mud system photo we shipped recently to our HDD industry client.


The working process is as below:
The submersible slurry pump pick up the used drilling fluids from the waste pit to desilter with double deck shale shaker: the first phase is bottom deck shale shaker to separate coarse solids so that the drilling fluids can be feed to desilter cone properly. The centrifugal pump feed the clean drilling fluids to desilter cone to separate fine solids with cut point 2~5 microns, the clean drilling fluids drop down into the mud tank, the user can add powder chemicals into the venturi hopper, the mixing pump provide proper pressure to help mixing evenly. The clean fluids are ready for recycling in the mixing compartment. The mud agitator and mud gun are agitating the fluids to prevent the solids suspension in the tank bottom.
