This week, GN Solids Control shipped two sets of oil-based cuttings processing equipment to Russia for the recovery of drilling fluids from oil-based cuttings. Considering the weather, the equipment is installed in the container, and this design will also make transportation easier.

The cuttings equipment is an important part of the closed loop mud system, which can recover more valuable drilling fluid and reduce waste discharge. Reduce drilling costs and protect the environment.

GN Solids Control not only provides a single unit, but also provides a cuttings handling system that includes different types of equipment. Vertical drill cutting dryers and settling centrifuges are key equipment in chip handling systems.

For oil-based drilling cuttings, vertical cutting drying units are ideal for separating drilling fluids and cuttings. The drying unit receives the cuttings discharged from the solid-controlled vibrating screen and operates at 900 rpm to effectively reduce the oil on the cuttings to 5%. We use a high-hardness scraper to push the separated chips off the screen. The high quality scraper ensures stable performance of the drying unit and low maintenance costs.

The fine particles flow out of the cuttings dryer through the sieve holes and enter the buffer tank. The waste slurry processing centrifuge is used to further separate the effluent from the dryer. We recommend using an ultra-wearable screw pump to deliver the mud from the buffer tank to the centrifuge for fine particle separation. The centrifuge was run at 3200 rpm to produce a separation factor of 2062 g, under which 2 micron sized fine particles would be removed. After treatment by a sedimentation centrifuge, the drilling fluid can be reused.

GN Solids Control offers vertical drill dryers and centrifuges with fixed speed or VFD variable frequency control modes. Customers can find almost all equipment for cuttings from the GN Solids Control product catalog. Sludge vacuum pump and screw conveyor for cuttings, vertical dryers for high temperature dewatering and high-speed centrifuges for fine cuttings. Please feel free to contact us if you have any requirements.

GN Solids Control is a professional supplier of solid-liquid separation solutions in the market. Recently, a batch of solid-state equipment is ready for shipment to US customers engaged in solid-liquid separation business. The equipment included in this order is a shale shaker and a large bowl centrifuge.

The shale shaker and the decanter centrifuge are two kinds of solid control equipment with different working principles. The shale shaker separates the solids using a wire mesh depending on the solid size, while the centrifuge separates the solids by centrifugal force. The shale shaker is mainly used for the separation of coarse particles, and the sedimentation centrifuge is mainly used for the separation of fine particles. Therefore, in a step-by-step solid-liquid separation system, the process steps of the centrifuge are always located behind the shaker.

GN Solids Control shale shaker are characterized by simple structural design and easy operation. The shale shaker is fully treated to make it strong and able to withstand high vibration forces. During the shale shaker transportation process, fix the shale shaker platform with fixing blocks and bolts. After reaching the scene, just loosen the bolts before the machine is running. The GN Solids Control shale shaker is fixed with a composite frame pre-tightening screen for long life.

GN Solids Control centrifuges use duplex stainless steel as the material for the bowl. The material has better machinability and centrifugal casting technology for better dynamic balance. For solid-liquid separation, GN Solids Control has a range of products to handle different capacities and applications. GN Solids Control centrifuges are not only widely used in drilling fluid solids control systems, but also widely used in environmental industries such as wastewater treatment and mud dewatering.

GN Solids Control offers a full range of solids control equipment for drilling mud recovery projects. At the same time, more and more customers from other industries will use solid-liquid separation equipment. For more information on GN Solids Control, please feel free to contact us.

Recently, GN Solids Control completed the production and commissioning of a 5m3/h oily sludge treatment system and prepared to send it to Guangdong for the oil sludge reduction treatment project.

This oil sludge treatment system consists of the following modules:

1) Heating premixed and tempered tank

2) Shale shaker module

3) Horizontal screw centrifugal separation module

4) Three-phase disc oil-water separation module (slope plate separation separation, oil-water separator, disc centrifuge, etc.)

5) Dosing system processing module

The solid phase oil content after treatment by GN Solids Control sludge system can be controlled within 3%, the total water solid content in the recovered oil can be controlled within 3%, and the oil content in the recovered water is within 3%, which can greatly reduce the solid phase material. The oil content rate reduces the total amount of materials to be treated, and also provides the maximum reduction guarantee for the later biodegradation, thermal desorption and other processes, and improves the treatment efficiency of oily sludge.

In order to better meet the customer’s requirements and provide the most effective sludge disposal solutions, we need our customers to answer the following questions:

Source and type of waste (drilling, refining, or other?)

Waste composition, oil content, water content, solid content?

What is the maximum particle size of the solid? Is there a solid particle size distribution?

Solid phase requirements, liquid phase requirements, use of processed materials?

With years of experience in the manufacture of oil drilling mud solids control systems, GN Solids Control is able to design and manufacture mud recovery systems in accordance with standard configurations or customer requirements. This week, a solid control system will complete the factory’s trial installation and testing, and then shipped to an oilfield customer in China.

The system is a stand-alone mud solids control system with solid separation and mud reconfiguration.

1. Separation equipment – The system is equipped with a GNZS703 shale shaker and two cyclone 10 inch desanders for solid particle separation. The coarse separation will be carried out on the shaker unit and the latter will be used for fine particle separation.

2. Pumping system – The pumping system consists of a submerged slurry pump, a sand pump and a mixing pump. Considering the replacement of the drilling tool, the mud system is equipped with a drill-down pump, so the mud tank is equipped with an in-tank compartment. To ensure adequate tank volume, we use a vertical mud pump to feed the desander. The mixing pump is used to circulate the polymer mud material to provide pressure to the mud gun.

3. Mud tank system – When designing the mud, we fully considered the division of the equipment and compartments installed on the mud tank to ensure the continuous workflow of the mud system. Pipes and valves are provided in the mud tank to facilitate mud flow. Aisles and handrails are provided to allow the operator to safely operate the tank.

GN Solids Control is standard on drilling mud solids control systems. We also offer custom configurations based on customer specific requirements for capacity and budget. Before placing an order, the customer will get a layout and flow chart to give a more specific impression of the mud system.
