Recently, GN Solids Control completed the design and manufacture of a sludge treatment unit for an oilfield environmental protection unit. Since the sludge treatment system was put on the market, it has received extensive attention from customers in the industry, and the feedback from the market on-site operation is good. More and more oilfield environmental protection business contractors use this system as an important solution to efficiently and economically reduce the content of harmful substances in sludge.

The oil sludge treatment system has two separation principles of chemical action and physical separation procedure, and consists of several modules with different functions to gradually recover the water and oil in the sludge. Here is an introduction to the system:

Sludge vacuum extraction module——The sludge from oil-based mud drilling cuttings has high viscosity and large sludge content, and requires a powerful and efficient conveying device to send sludge from the sludge pit to the sludge treatment system. GN Solids Control Sludge Vacuum Pump is a full pneumatic conveying pump without electrical components. It does not generate any sparks during use, and is especially suitable for oil and gas explosion-proof environments. The vacuum degree of 85Kpa can suck and discharge viscous sludge sludge to a long distance.

Pre-mixing module—Before the sludge is sent to the separation module, the material needs to be homogeneously mixed to a liquid content of more than 80%. At the same time, in order to enhance the separation effect of oil and mud, chemical agents need to be added during the homogeneous mixing process.

Separation module-GN Solids Control uses different separation equipment to separate oil and water from the sludge step by step. This design guarantees the continuity of the construction process, and the load of each step process is accurately calculated to avoid bottleneck processes. Shale shaker are used for two-phase separation of coarse solids and liquids. The centrifuge can remove most of the fine solids in the wastewater discharged by the shale shaker, so that the three-phase disc separator will not be overloaded when separating oil, water and ultra-fine solids. GN Solids Control innovatively arranges the swash plate sedimentation device between the centrifuge and the three-phase disc player to ensure that the three-phase disc machine works normally without blocking.

This set of sludge treatment system is very complete in configuration, covering almost all sludge separation equipment, and has very complete functions. Under the premise of ensuring complete functions, GN Solids Control has accurately designed the sludge system, so that all equipment is installed on 3 skids, which has the characteristics of compact structure and convenient transportation.

Non-excavation construction is a horizontal drilling project applied to construction or infrastructure projects. During non-excavation construction, drilling mud needs to be used to ensure the performance of the non-excavation rig. To make drilling mud reusable and reduce drilling costs, contractors often use mud recovery systems to recover drilling mud.

GN Solids Control has more than ten years of experience in the design and manufacture of mud recovery systems. Especially in non-excavation projects, it has multiple bell compact mud systems available for customers to choose from. According to the different requirements of users and the site area limitation, GN Solids Control can provide different configurations of mud recovery devices to meet the requirements of different working conditions. There are usually two types of mud purification systems suitable for non-excavation construction: one is a sand removal cyclone purification system, and the other is a self-contained mud recovery system.

The desander system has a small footprint and is economical. The system consists of a cyclone and a shaker, both of which are mounted on a small collection tank. The sand removal cyclone purification system is a two-stage separation device whose function is to remove coarse particles from drilling mud. The sand removal cyclone purification system is mainly used in projects that can accept large-diameter solid drilling mud, such as piling projects.

GN Solids Control’s self-developed high-grade mud recovery system can be divided into four stages: coarse rock cuttings, sand, mud, and ultra-fine solids. The mud tank of the high-equipped mud recovery system is larger and has enough space to store the purified drilling mud. At the same time, it has more tank surface space for more separation and purification equipment. When the tank surface space is sufficient, the customer can also choose a centrifuge to reduce the ultra-fine solid phase in the drilling mud to avoid the ultra-fine solid phase from being concentrated in the drilling mud. GN Solids Control not only has standard model solids control system optional, but also provides custom designed mud recovery system for customers to purchase. If you have any such requirements, please feel free to contact us.

Recently, GN Solids Control shipped a set of sludge treatment system to a China domestic customer. At present, the system has been completely installed and commissioned.

This sludge treatment plant is mainly used for recovering oil from industrial oily sludges such as oily sludge produced at the drilling site, and oil sludge from refinery tank cleaning. After treatment, the recovered oil can be used as fuel or sold for profit; the oil content in the recovered water and solids is small, and it is easy to detoxify by further processes.

The GN Solids Control sludge treatment system is a stepped three-phase separation system. It mainly consists of the following modules:

Premixing module — The premixing module is used to collect sludge. Different sources of sludge have different solid contents and different viscosities. This will pose a huge challenge to sludge treatment. The GN Solids Control sludge separation system requires the solids content of the feed sludge to be less than 20%. Therefore, in the mixing module, the operator needs to add water to dilute the sludge, and at the same time, the chemicals and the diluted sludge can be fully mixed and stirred.

Large particle separation module-A drilling fluid shale shaker is installed in this module to remove large particles of solids in sludge, thereby reducing solids content. This procedure can greatly reduce the workload of subsequent sedimentation centrifuges.

Solid-liquid separation module-a decanter centrifuge in this module is used to remove fine particles from the material. This module mainly separates the mixed liquid (water-oil mixture) and solids. The separated sludge is returned to the homogenizer for washing, and the liquid is sent to the next step for further processing.

Three-phase separation module-disc high-speed separator is used for three-phase separation of oil, water and ultra-fine solids. During this process, the solid content of the feed mixture should be less than 3%, and the solid size should be less than 400 microns.

For the transportation of sludge materials, we recommend the use GN vacuum pumps, which are suitable for high-risk gas explosion-proof areas. In addition, we also provide container-type chemical dosing devices for adding chemicals to sludge treatment systems.

Non-excavation mud clean system is an important part of the GN Solids Control system. Based on its compact structure, small footprint and high efficiency, it is widely used in mud treatment in urban infrastructure construction. As a country with rapid development of infrastructure construction, the construction of underground pipeline networks in urban infrastructure construction in India has also become very busy. Underground pipeline network construction is carried out by non-excavation companies after winning the bid, so non-excavation companies generally have multiple rigs and purification systems. Generally, each drilling rig needs to be equipped with a mud recovery system, corresponding to the processing capacity of the related drilling rig. GN Solids Control has exported multiple HDD mud recovery systems to India.

The standard non-excavation mud recovery machine system consists of mud recovery equipment, mud mixing equipment and mud collection tanks. Unlike the mud recovery device in the oil and gas drilling industry, non-excavation drilling first discharges the mud back to the mud pit on the ground, and then uses a vertically installed submerged slurry pump to transfer the mud to the mud recovery system. Purification system, Shale Shaker, Desander, Desilter, and progressive removal of rock cuttings and solid waste. This is a standard configuration. If there are higher separation requirements, we will add a centrifuge to the system as a fourth-stage processing equipment to control the solid particle diameter of the slurry at 5-10 microns.

The size of the mud tank usually depends on the size of the rig and the volume of mud that needs to be stored. On the mud tank, a stirrer and a mud gun are needed to stir the mud to suspend the solids in the mud. To configure the proper mud, a jet mixing system is needed to add chemicals to maintain the properties of the mud.

GN Solids Control high-profile mud recovery bears have different sizes and design schemes and are widely used in oil and gas drilling, non-excavation drilling, piling, TBM and other separation projects. GN Solids Control is pleased to provide you with professional products and configuration information about mud recovery systems, please feel free to contact us if you are interested.
