Containerized Oil Sludge Treatment System for Europe Client

BY gnadmin 20 October 2018 decanter centrifuge, oil sludge separation system, Shale Shaker

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.

Complete Oil Sludge Treatment System Ready for Delivery

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.

6 Sets ViST Vacuum Shale Shaker for Offshore Project

BY gnadmin 30 September 2018 drilling waste management, ViST vacuum shale shaker

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.
If you are interested in GN ViST vacuum shale shaker, pls contact with GN solids control.

Waste Water Treatment Decanter Centrifuge for Russia Clients

BY gnadmin 24 September 2018 decanter centrifuge

This week GN shipped several units of waste water treatment decanter centrifuge to Russia, The model is GNLW363C-VFD, This is one of the most popular model decanter centrifuge among GN equipments, it can be applied for many industries including waste water treatment, drilling fluids recycling/ cleaning, dewatering unit, drilling waste management system, dredging slurry separation system, industrial waste water treatment and all the other liquid solids separation application.

There are many size decanter centrifuge for option, 9 inch, 14 inch, 18 inch, 22 inch, 30 inch with different treating capacity, the treating capacity for different material varies a lot for the same bowl size. For the same bowl size, we have different ratio when used for different industry, for example, 9 inch bowl centrifuge have models of GNLW223 and GNLW224, GNLW224 with longer bowl length, the ratio is 4, with better performance in separation, discharge fluids is more clear, the discharged solids is drier, it is an ideal decanter for the dewatering fluids, when the client need to get pure water to send to waste water treatment plant or drain off to the river/ pond.

The 14 inch bowl also have GNLW363 and GNLW364, The 18 inch bowl also have GNLW452, GNLW453-VFD, GNLW454-VFD for option, the 22 inch bowl also have GNLW553-VFD, GNLW554-VFD.

Drilling fluids mud agitator and slurry vacuum pump shipped to China client

BY gnadmin 15 September 2018 centrifugal pump, drilling waste management, mud agitator, vacuum pump, vertical cuttings dryer

56 units of drilling fluids mud agitators and 3 units slurry vacuum pump shipped to China client this week.
The mud agitator is consist of electric motor and gearbox and skid, it is installed on the mud tank to prevent the solids from accumulation on the tank bottom. The mud gun length and mud agitator shaft length is customized according to mud tank inner depth. GN mud agitator have C version and D version, the C version mud agitator is that the electric motor and gearbox is connected by coupler , if the client need local standard motors or they want to install their own motors, they can buy the gearbox with coupler and skid, and install the motor locally to meet the special explosion proof standard. D version mud agitator is the lastest mud agitator, the gearbox and electric motor is connected directly, with compact design, it will save space on the mud tank, and easy for maintenance.
The slurry vacuum pump is the most popular drilling cuttings transfer pump since this year, with the advanced technology. It is a pneumatic slurry transfer vacuum pump for liquid, slurry, and solids transfer. The pump can transfer material with high gravity and high density, solids content max. up to 80%.
GN solids control can offer various pumps, including submersible slurry pump, centrifugal pump, screw pump, vacuum pump for different applications. Vacuum pump is our new products, we already sold it to many jobsites in the world.
