Introducing GN Oil Sludge treatment System.

A client in Iraq asked me about an oil sludge treatment system last Wednesday, and I am here to share with you some details about this package.

This is a stock of 1m3/hour GN oil sludge treatment systems available for sale in China. This system can be used for treating oil sludge from oil fields, wastewater, oil recovery, and the separation of solids/water/oil in various fields.

The results after treatment with the Oil Sludge Treatment System are as follows:

  • Oil content in solids: less than 2%
  • Oil content in water: 500 ~ 1000ppm
  • Water and sediment content in oil: less than 3%

GN also supplies a microbubble water processor, which can be used to reduce oil content in water to 50 ~ 100 PPM.

This oil sludge treatment system storage has a capacity of 1m3/hour, calculated based on a solids content of less than 20%.

It includes a pre-mixing tank, shale shaker, decanter centrifuge, disc separator, polymer dosing unit, and accessories.

The working procedure for the oil sludge treatment system is as follows:

  1. Pre-mixing tank: Heat and add chemicals to the used oil sludge to reduce the solids content to less than 20%, making the sludge pumpable/fluid.
  2. Shale Shaker Unit: To mechanically separate coarse/large solids using a screen, usuallyGN594J.
  3. Two-phase decanter centrifuge unit: To separate fine solids and liquids, with further treatment of the liquid using the disc separator, it could be used different models based on work site condition.
  4. Three-phase disc separator unit: To separate oil, water, and small/fine solids in the liquid from the decanter centrifuge.
  5. There is a set of chemical dosing units for this system, and the chemical materials usually include demulsifiers and flocculants.190329 Oil Sludge Treatment Equipment

Liquid Mud Plant: A Key Piece of Equipment for Drilling Operations

Drilling is a complex and dangerous opeLiquid mud plants are one of the most important pieces of equipment in a drilling operation. They are used to produce and circulate drilling mud, which is a fluid that is used to lubricate the drill bit, remove cuttings from the borehole, and control formation pressure.

Last Tuesday, I received an inquiry from a customer about our liquid mud plants. I replied with some pictures of our tank system, which is a part of a mud plant. However, the customer needs more details.

2023.06.29 Solids Control System

The liquid mud plant typically consists of storage tanks (usually cylinder tanks)with a mud system, but the system is not all the same as a solids control system. A mud plant tank system including the following equipment: The Hopper with Agitators, centrifugal pumps,  Shale shaker (as well as mud cleaner), and sometimes centrifuges are also necessary.


The agitator mix the drilling mud ingredients together, such as barite added from the hopper. GN supplies two types of mud mixers that are useful in a tank system: jet mud hopper and shear hoppers.

The shale shaker separates the drilling mud from the cuttings. GN typically recommends the GNZS-594 for mud separation. In addition, a shaker can be installed with desanders and desilters to create a mud cleaner. GN supplies 2S12N or 3S16N mud cleaners with 594 bottom shakers.

The centrifuge removes very fine particles from the drilling mud. The specific model of centrifuge will vary depending on the specific requirements. Usually, we supply 363, 453 and 553 models.

The centrifugal pump moves the drilling mud or barite through the separation equipment and hopper or pumps the mud to the storage tanks. All the spares of GN C-pumps are replacement with Magnum pumps.

Besides, a complex mud plant might need degassers or screw augers for degassing or screw muds. A vertical cutting dryer is necessary when treating OBM.

A liquid mud plant is essential for safe and efficient drilling operations. The mud must be mixed to the correct specifications, and it must be circulated through the drill bit at the correct rate. The cuttings must also be removed from the mud on a regular basis.

I hope this blog post has been helpful in providing you with an overview of liquid mud plants. And I had already shared with my clients the brochure of the mud system and equipment introduction. If you also have an inquiry of a mud plant, please contact me at

An Introduction of Lifting, Transportation and Installing of a GN Shale Shaker.

This blog post provides instructions on how to safely move and install a GN shale shaker. It covers topics such as lifting, transportation, installation, leveling, and electrical connection. Please read this blog carefully before using the shale shaker to avoid any accidents.

1. Lifting

When lifting, attach the lifting sling only at designated lift points. Four Lifting points are attached to both sides of the bottom base of the shaker. Use all four lifting points to lift equipment to prevent damage.
WARNING! When lifting equipment, use spreader bars to prevent damage. Only attach the lifting sling to the designated lifting points to ensure that the unit is properly balanced and oriented when it is raised, and to prevent damage to components. Do not attempt to lift the equipment by attaching the sling to the motor or any other location. Be sure the handling devices have sufficient lifting capacity to handle the weight of the equipment safely. The motor cord can be damaged if entangled with the lifting sling. Keep the cord away from the slings during lifting.
Lifting Arrangement

2. Transportation

As shown in Figure 3-2, four shipping brackets near the springs secure the equipment during transportation. Each shipping bracket consists of a fixing base and two fixing bolts for the shaker deck. All four shipping brackets must be installed before the shale shaker is shipped from the factory. The shaker deck may be locked during shipping to prevent damage.
After the shale shaker has been finally positioned and leveled, the shipping brackets should be removed and stored (as shown in Fig. 3-3). Do not discard the shipping brackets, as they will be needed the next time the equipment is moved. Be sure to install the shipping brackets again before moving the shale shaker, and remove them before starting the equipment!

3. Installation

After transporting the shale shaker to the job site, position and level it. To install the shaker, align the 4 mounting holes on the shaker with the four Φ24 mounting holes on the base, and screw them together. Prepare the corresponding front, back, left, and right positioning blocks to facilitate handling, disassembly, and reinstallation. If the shale shaker is supplied with the mud system, GN has designed and manufactured the corresponding installation and positioning work, and the user only needs to connect and fix the shale shaker after arriving at the site.
Connect the power supply to the magnetic starter of the shale shaker vibrator motor. The electrical system is generally 380 V/50 Hz unless the user specifies otherwise. The magnetic starter and vibrator motor of other electrical systems can be designed and manufactured according to the user’s requirements.
The “ON” and “OFF” markings on the start button of the shale shaker control panel are printed in the standard colors for these functions.
The shale shaker can be installed directly on a level workbench. Two or more shale shakers can be combined as a tandem or tridem shaker. the connecting pipes and circuit breakers must be on power for combined use.
Make sure that there is enough space around the equipment.

4. Equipment Leveling

To ensure that the mud is evenly distributed on the screen, level the shale shaker using a leveling instrument. If the equipment is not level, use non-compressible gaskets to level it.

5. Electrical control panel junction

Open the cover of the control panel, and connect the facility’s electrical power to the junction box
The vibrator motors are 3-phase, 50 or 60 Hz motors, The motors must be operated at the designed voltage. Please view and refer to the label on the motor nameplate for motor power requirements.
WARNING! The vibrator motor must be operated at the designated supply voltage. High voltage may be present. Be sure that the circuit breaker is turned off and the power supply is locked out and tagged out before performing any maintenance or adjustments. Electrical connections must comply with the National Electrical Code (NEC) and all applicable local codes. Failure to comply could result in an unsafe condition that could injure personnel and/or damage equipment. Ensure that all electrical and conduit connections are secure.
I hope this blog post has been helpful in providing you with instructions on how to safely move and install a GN shale shaker. Please remember to always read this blog carefully before using the equipment and to follow all safety precautions. I will write more details about the shaker screen and the mud cleaner installation next week. If you have already purchased GN shakers and have questions, please contact me at

This week, I am Focusing GN Dewatering system in Soil Treatment.

The GN sludge dewatering system is applicable to bottom sludge cleaning projects in various fluids including water-based sludge.

The GN sludge dewatering system adopts the step-by-step treatment design principle. According to the particle size contained in the sludge, the solid phase is separated from the fluids through different separation equipment including the shaker and the centrifuge. The following is a brief introduction to the main equipment and operating principle of this system:

Shale shaker- High G GNZS594 and Vist GNZS594: In this system, the first stage separation equipment is a single GN shale shaker, which can effectively separate the coarse particles in the suspension through the screens with different mesh sizes, to reduce the load of subsequent separation. A Vist shaker uses a combination of vibration and vacuum to remove cuttings from the drilling fluid.

mud cleaner

Hydrocyclone units: The sludge treated by the shale shaker is sent to the mud cleaner, to separate particles with a size of approximately 75 microns and 20 microns from the fluids, respectively. The system is equipped with four sludge centrifugal pumps, which are used as feed pumps for the desander and desilter cyclones equipment installed on the shaker.



Decanter centrifuge: To obtain more clarified water, a sludge dewatering centrifuge must be used to separate the fine particles in the muddy water. The projects generally require a relatively large flow, so GN is equipped with the largest GNLW764A-VFD drainage centrifuge that can be produced. The diameter of the bowl of this centrifuge is 760mm. During operation, the maximum separation factor can reach 2650G. The solid phase of 2 ~ 5 microns can be separated, which makes the separated liquid phase clearer.

In addition to the separation equipment, GN is also equipped with sludge storage tanks for temporary storage and liquid reception in this system. At the same time, the solid slag from the discharge equipment is also equipped with screw conveyors to transport the slag to the outside of the system. The GN  sludge dewatering system is a high-efficiency and high-performance system that can help customers effectively clean the sludge of soil.
