The oil sludge treatment system is one of the separation solutions promoted at home and abroad in recent years. It is mainly used to treat sludge from oil field drilling, oily wastewater from refineries and sludge from oil storage tank bottom sludge.

GN Solids Control currently has three standard models of sludge handling systems with processing capacities of 1-2, 5-10 and 15 cubic meters per hour. The picture below shows the GNOST-05A produced by domestic customers in China.

The GN Solids Control sludge treatment system consists mainly of the following modules:

1. Premixing module – This module includes a mixing tank, a stirrer and a transfer pump. First, the sludge is diluted in the tank to make the sludge more fluid and easy for subsequent module processing. Water and chemicals are added to the storage tank, and as the temperature of the heating system increases, the emulsified oil separates from the solid to become a demulsification mixture.

2, coarse screening module – a high G shale shaker is the key equipment of the module. The coarse particles will be removed through the screen. In order to prevent sludge splashing, the vibrating screen is also equipped with an anti-splash device.

3. Three-phase separation module – This module is combined with a centrifuge assembly and a disc centrifuge assembly. The centrifuge is used to remove most of the solids in the sludge to reduce the solids content. The liquid phase will then be sent to a disc centrifuge for separation of fine oil, water and ultrafine solids.

4. Chemical Dosing Device – GN Solids Control provides a container chemical dosing device that distributes chemicals to each module in the system. The containerized design makes the module easy to transport.

GN Solids Control has extensive experience in the development of this type of sludge handling system. A large number of case studies have been available at home and abroad for reference. For more information on GN Solids Control sludge handling equipment, please feel free to contact us.

The drilling and drying system is a major component of the closed loop system for drilling fluid treatment. It recovers as much of the drilling fluid as possible by handling the cuttings with high humidity. This week, GN Solids Control completed the manufacture of two vertical drill chip dryer systems and will ship them to Xinjiang customers soon.

Oil-based drilling cuttings are mostly treated with vertical drying systems. The entire system consists mainly of a cuttings drying module and a fine particle removal module. Each module has a critical core device.

Cuttings drying module

The vertical cutting dryer is the key equipment for the drying module. Usually, the cuttings are fed into a cuttings drying device. Under the action of centrifugal force, the oil will be separated from the cuttings and passed through the sieve holes into the collection tank in the drying device. The dry screen has an opening size of 250, 350 and 500 microns and can be used for different sizes of cuttings drying. The GN Solids Control cuttings dryer is equipped with a flushing system and an air knife system for cleaning the mud collecting tank and the screen to avoid clogging.

Fine particle removal module

The high specific gravity mud purification centrifuge is the key equipment of this module. The liquid effluent from the dryer will be pumped to a high specific gravity mud purification centrifuge for further processing to remove fines from the drilling fluid. In order to ensure the performance of the centrifuge, GN Solids Control takes into account the high-speed operation, the protection of wearing parts and the use of materials in the manufacturing process. Long-term operation and less maintenance ensure the efficiency and economic benefits of the equipment.

In drill cutting systems, mud tanks are used to install equipment and collect and store drilling fluids. The chips entering the dryer from the drying device and the centrifuge can be conveyed by a screw conveyor device, which is a conveying device widely used for conveying solid phase materials.
