This week GN solids control shipped three containers of shaker screens to America warehouse, every month GN will ship thousands of shaker screens to Houston, USA to sell to our clients in North America and South America.

GN solids America is the branch company of GN solids control in Houston, USA, we have various models shaker screens stock in the warehouse, including:

Composite material frame replacement shaker screens of Mongoose shaker, dimension is 585x1165mm, all the API size higher than API 60 use 3 layers SS 316 wire mesh, the composite frame last longer than traditional steel frame screens, not easy to get rusty, it can be storage up to 5 years, and the effective screen area is 20% larger than steel frame screens.

Composite material replacement shaker screens of Brandt Cobra family screens, Venom screens, VSM 300 primary screens, VSM 300 secondary screens
Composite material replacement shaker screens of FSI shaker
Except for shaker screens, GN solids America also have linear motion shale shaker, linear motion mud cleaner, decanter centrifuge, vertical cuttings dryer, centrifugal pump, and spare parts in stock there for immediate shipment. All the equipments motor and control panel with IEC explosion proof certificate, which is acceptable in America.

If the client need a customized solution for HDD mud recycling system, oil sludge separation system, drilling waste management system, solids control system, vac hydro slurry treatment solution, pls contact with GN sales engineer. We can provide solution for all the applications for liquid and solids separation.

This week GN solids control shipped one unit of HDD mud recycling system and dewatering unit to Sinopec project. HDD is one of our major applications, GN equipments 4 major applications including oil & gas industry solids control system and drilling waste management system and oil sludge separation system, HDD & CBM industry mud recycling system, Piling & TBM desander unit, Industry waste water treatment.

The technical configuration is as below:
1) 3 phase cleaning mud recycling system mud tank, with containerized frame for convenient transportation, the user can put the mud tank and the frame with equipments on the trailer and move to another site from one site.
2) 1 unit of GNZS703F shale shaker as the first phase cleaning equipment, equipped with 3pcs of durable composite material shaker screens with customized API mesh screen. We produce OEM composite material shaker screens from API 20 to API 325 as per client’s requirement.

3) 1 unit of GNZJ703F-1S8N mud cleaner, with under flow shaker, desander cone and desilter cone combination unit. Equipped with 2 units of centrifugal pumps as feeding pump of desilter cone and desander cone.
When the drilling fluids temperature is over 70 degree, we will use special material hydrocyclones for longer working life.
4) Dewatering system with same dimension mud tank
5) Decanter centrifuge GNLW363C-VFD is the 4th stage cleaning to separate fine solids smaller than 15 microns. After several years working, more and more fine solids are accumulated in the tank bottom, these fine solids can not be separated by the desilter cone, then high speed decanter centrifuge is required to clean the drilling fluids, otherwise it can not be reused for drilling again.

Last week, GN finished production of 2 m3/h oil sludge separation system for USA client, this week, we finished production for 15 m3/h oil sludge treatment system for Europe client, this is the repeat order for this client, they bought one unit of 1 m3/h compact design oil sludge separation system for the same project. They are satisfied with the separation result, so repeat order for a bigger treating capacity system.
The configuration of the containerized 15m3/h oil sludge separation system:
1) Premixing tank: The sludge vacuum pump transfer the oil sludge from the waste pit to the pre- mixing tank, which is equipped with heating line inside the tank around, and the mud agitator installed on the tank to agitate the oil sludge to prevent the solids from accumulation in the tank bottom. The system will be used in cold weather area, we put them in the container to keep the equipments warm.

2) Shale shaker tank, to separate coarse solids from the oil sludge, this is to protect the decanter centrifuge, coarse solids will wear the centrifuge screw very quickly, GN decanter centrifuge screw is made of stainless steel 304 by heating, the flights are protected by tungsten carbide tiles, it is fixed by special glue and bolts.

3) Decanter centrifuge modular: With one unit of 22 inch bowl decanter centrifuge installed inside the 40ft container, the screw pump is installed on the centrifuge skid, the screw conveyor is installed under the centrifuge solids discharge port to transfer the solids outside the centrifuge container.

One set of complete oil sludge treatment system ready for delivery this week, this is a 2m3/h customized design oil sludge treatment system as per client’s requirement. The main purpose of the client is to recover the oil from the oil sludge. It can be widely used for refinery oil tank bottom cleaning, oil sludge separation, oil based cuttings treatment, contaminated soils treatment, hazardous waste treatment, etc. applications.

The technical configuration is as below:
1) Premixing Tank Module
The vacuum pump transfer the oil sludge from the waste pit to premixing tank, which is equipped with heating lines, mud agitator, the oil sludge will be washed, heating and agitating, mixing with chemicals for flowability.

2) Classify System: The oil sludge from premixing tank will be transferred to a V bottom tank with screw conveyor on the bottom for solids sedimentation and liquid classification. The top layer will flow to disc centrifuge for oil and water separation. The bottom layer will be washed with chemical jetting, which will be shipped to solids control module.

3) Solids Control module
The solids control module consist of course solids shale shaker and fine solids decanter centrifuge, the 2 panel shale shaker is the mini shale shaker among GN all the shale shaker models, it will reduce the solids content and separate the big solids bigger than 1mm, so that the decanter centrifuge will not be damaged.

The decanter centrifuge is the mini decanter centrifuge with 9 inch bowl, the highest speed is 4500rpm, the separation cut point is 2~5 microns. With good efficiency of the centrifuge, the clean fluids will flow to disc centrifuge for water oil separation, otherwise the high solids content will influence the separation result of the disc centrifuge.

GN ViST vacuum shale shaker is a shaker unit with a vacuum suction hopper installed under the last shaker screen. The purpose to use the ViST vacuum unit under the shale shaker is for more recovery of the drilling fluids in the same conditions compared with shale shaker without ViST system, and the discharged drilling cuttings will be much drier, so the user can save cost to treat and disposal the drilling cuttings. Normally it is very difficult for the offshore drilling cuttings collection, treatment and disposal, sometimes client will ship them back to drilling waste management facility in land, the collection and shipment cost is very high, other clients use cuttings re-injection technology, some clients use Thermal desorption unit, some clients installed drilling waste management on the offshore rig floor, but normally the area for offshore drilling rig is very limit, it is hard to install a complete vertical cuttings dryer system. Because of these reasons, ViST vacuum shale shaker became very important for offshore.

As a professional solids control and drilling waste management system manufacturer in China, GN solids control, GN solids control keep developing new and advanced technology for oil & gas industry and provide the best solution for our clients.
Features of ViST Vacuum Shale Shaker

1. GN ViST vacuum shale shaker is suitable for oil based mud, water based mud and Synthetic oil based mud.
2. By using the ViST vacuum shale shaker, the drilling fluids recycling will be increased by 30%~50%, It greatly reduces the volume of drilling waste and the cost to transport the drilling waste.

3. By using this ViST vacuum shale shaker, no need extra high G drying shaker again; The compact design did not take much area at site.
