GN Solids Control finished a package of Oily soil leaching solid-liquid separation system. The separation package is sold to customer in the Middle East for the contaminated soil treatment. The system is designed to treat the oily sludge and oily soil.

Below are the major separation modules included in the contaminated Soil Washing and Separation system:

Module 1: The vacuum transfer unit. There is a solids and sludge vacuum pump used for transferring the waste material from waste pit. The vacuum pump is a 100% air driven device, there is no electrical components. Hence, there is an air compressor to feed air for the vacuum pump. And there is an air tank equipped after the air compressor and before feeding air for vacuum pump.

Module 2: The pre-mixing and washing unit. There is a tank with heating pipes. The vacuum pump transfer oily sludge or oily soil into the tank. Water will be feed into the tank to dilute the sludge and oily soil. After this stage, there will be oil, water and sand mixture.

As the viscosity and density of oil sludge is normally high. It is very difficult or nearly impossible for separation. There is a heating system used for together with the heating pipes for heating the oily sludge. The most suitable temperature is 70℃ ~ 80℃, which is the most suitable temperature to keep the activity of chemicals.

Module 3: Coarse shake separation unit. The coarse shale shaker is to pre-separate the big particles and sands from the oily sludge. As the solids contents are very high. The big opening PU screens are used in the shaker for longer service time.

Module 4: The decanter centrifuge separation unit. It is used for liquid and solids separation.

Module 5: The 3-phase separation unit for oil, water and solids separation. 3-phase centrifuge are used in the unit.

Module 6: Chemical dosing module. Chemicals are used nearly in all process. There is a skid mounted chemical dosing unit in the system to supply chemicals.

If the oil sludge discharged from oil sludge treatment is directly discharged without treatment, it will not only occupy a large amount of land, but also contain a large amount of heavy metals and bacteria, which will produce foul odors and cause serious pollution of water, soil and atmosphere.

At present, there are many treatment technologies for oily sludge, in accordance with the requirements of reduction, harmlessness, resource utilization and comprehensive utilization.

The main treatment methods of oily sludge waste in oilfields are as follows:

1. Incinerate in a high temperature incinerator. Oilfields often use thermal desorption unit (TDU). The sludge is incinerated to recover clean oil and water, and the oil content in the solid waste is reduced to less than 0.5%. The products that meet the standard will be landfilled or fired bricks. This treatment method is costly and causes coking, which affects the normal operation of the incinerator. And energy cannot be recovered efficiently. If the oily sludge has a high moisture content, the temperature in the incinerator will decrease after entering the incinerator, and the pollutants after incineration will not be able to reach the standard stably, which will lead to air pollution and dust pollution.

2. Treat oily sludge by drying ordinary sludge. Because of the particularity of oily sludge, common processes and machines are not suitable for the treatment of oily sludge, which leads to agglomeration and coking of oily sludge in the equipment, making the equipment scrapped. In addition, the oily sludge treated by the ordinary sludge drying process cannot meet the standard. For example, equipment such as rotary kiln sludge dryers will form coking inside the equipment in a short period of time during the process of processing oily sludge, causing the equipment to fail to operate normally.

3. GN Solids Control Use chemical hot washing to treat and recycle oily sludge. As far as China’s current situation is concerned, chemical hot washing is mostly used for oil recovery from oil sludge, with the purpose of recovering oil. Therefore, the oil sludge after hot washing is a non-standard product and still needs to be treated. Therefore, the hot washing method can only be used as an auxiliary method for reduction, and cannot be used as a direct oil sludge treatment method.

Last week, GN Solids Control compete the production of 10 sets drilling mud shale shaker for an offshore drilling company in China for their international drilling activities. The shale shaker supplied for the project is model GNZS595, which is a 5-panel shale shaker.

Besides the 5-panel shale shaker, GN Solids Control also make various sizes 2-panel shale shaker, 3-panel shale shaker, 4-panel shale shaker, and double deck shale shaker. Mostly, clients prefer the linear motion shale shaker. GN Solids Control is also capable to make dual motion shale shaker. Other shale shaker supplier need to use 3 vibrationg motors to reach the dual motion: Linear and Elliptical Motion. GN Solids Control adapts 2 special design motors, Clients can adjust the motor G force to choose linear motion or Gradual elliptical motion.

GN Solids Control shale shaker is complete with 2 vibrating motors, control panel, weir feeder, composite frame pretension screens, and tool box. There is a smal collection mud underneath the shaker deck, plus, there are side discharge port at the shaker deck. Operators can choose to discharge drilling mud from bottom of shaker deck, or at side of the shaker deck.
Clients can choose any types of GN shale shaker, and combined it with desander cyclone and / or desitler cyclone to run it as desander separation, desilter separator or drilling mud cleaner.

Besides shale shaker, drilling mud agitator is another popular equipment in drilling mud solids control system. Mud agitators are widely used at shale shaker tank, mixing tank, reserve tank, suction tank to avoid mud settle down. Mud Agitator is composed of a driving motor, gearbox reduce, shaft, impeller / impeller, tank bottom stabilizer. Gearbox reduce ratio is important for the agitator performance. If the rotating speed is too slow, the mud may be settle down during and circulation. If the agitator rotating speed is too high, it may cause more fast worn out of the gearbox and may be damage the balance of drilling mud. Normally, the agitator speed should be less than 100RPM.

Drilling mud agitator is widely used in drilling mud systems. It is equipped in all kinds of mud tanks to avoid solids settling down, like in sand trap, mixing tank, reserve tank, centrifugal tank, etc…

The Mud agitator is composed of driven motor and gearbox. The motor and gearbox are connected via coupling or flange, and driven the shaft to rotate. There are canted impeller / impellers fixing on the shaft to protect the drilling mud from settling down.

According to the connection face of driven motor and gearbox, there are horizontal mud agitator and vertical mud agitator. Clients choose the suitable model based on the mud tank situation.

GN Solids Control makes various sizes drilling mud agitator to fit for clients’ applications. This week, GN Solids Control finished some mud agitators for an offshore platform. The agitators are customized per client’s color. GN Solids Control make shaft to suit for the tank inner depth. And the canter impeller size and quantity is designed to accordance with the motor power and tank size. Plus, in order to avoid the agitator shaft hanging during rotating, GN Solids Control make tank bottom stabilizer to support the agitator shaft inside the mud tank. It can also improve the service time of the mud agitator.

During assembly, the operator should adjust the gap between the stabilizer and the shaft to make the gap between the stabilizer and the shaft uniform to ensure concentricity. If the concentricity of the stabilizer and the shaft cannot be guaranteed, the agitator will be noisy and the gearbox reducer will be easily damaged.

Correct and suitable lubrication is vital to ensure stable running of mud agitators. Most problem of mud agitator are caused by unsuitable lubrication, or the lock of lubrication.

Besides mud agitator, GN Solids Control is capable to make full line drilling mud solids control equipment.
