GN Containerized Oil Sludge Treatment Plant for Africa Client

GN Solids Control has successfully supplied a fully containerized oil sludge treatment system to an African client. This compact, skid-mounted plant is designed to treat oily waste from crude oil tank cleaning, refinery ponds, and drilling operations. The system enables the recovery of valuable oil, recycles water, and significantly reduces solid waste volume—all while meeting stringent environmental standards.
The entire plant is integrated into standard shipping containers, making it ideal for Africa’s infrastructure conditions where ease of transport, rapid deployment, and relocation between sites are critical. The modular design also allows future expansion and simplified maintenance.


The system consists of four core modules:
(1) Pre-Mixing Tank Module
The pre-mixing tank module is the first step in the treatment process. Raw oil sludge often has high viscosity, high solids content, and poor fluidity. This module heats, dilutes, and conditions the sludge to create a homogeneous slurry suitable for downstream separation.


(2) Shale shaker Module
After pre mixing, the sludge still contains large debris, stones, and coarse sand. If these particles enter the centrifuge directly, they will cause accelerated wear and reduce separation efficiency. The vibrating screen module removes these oversized solids as a protective step.
(3) Three Phase Decanter Centrifuge Module
Including three phase decanter centrifuge, its feeding pump, fluids catching tank and skid. This is the core separation unit of the entire plant. The three phase decanter centrifuge simultaneously separates oil, water, and solids from the conditioned sludge using high centrifugal force. It is particularly suitable for oily sludge with wide fluctuations in oil content and complex compositions.


(4) Chemical Dosing Module
Effective chemical treatment is essential for breaking emulsions and enhancing separation efficiency. The chemical dosing module automatically prepares and injects flocculants, coagulants, and demulsifiers into the process stream.

Two Package Drilling rig Solids Control Equipment for Middle East Client

Recently two package of drilling rig solids control equipments are shipping to Middle east client. The equipments list including:


1. 6 sets of drilling fluids shale shaker
As the first phase of solids control, these high-performance shakers are engineered to remove large cuttings and debris from the drilling fluid. With high G-force output and large screen areas, these six units ensure that the client can maintain high circulation rates while efficiently separating solids, protecting downstream equipment from abrasive wear.
2. 2 sets of drilling fluids mud cleaner
Positioned downstream from the shakers, these mud cleaners combine desanders and desilters in a compact unit. They are critical for removing fine sand and silt particles (15-74 microns). By integrating hydrocyclones with a fine-mesh shaker screen, these two units will allow the client to significantly reduce dilution rates and lower overall mud costs.


3. 4 sets of drilling fluids decanter centrifuge
For fine and ultra-fine solids separation, the four decanter centrifuges represent the pinnacle of the system. Operating at variable speeds, these centrifuges will recover barite, remove colloidal solids, and ensure that the drilling fluid maintains the precise density and viscosity required for challenging Middle Eastern formations. GN decanter centrifuge has been widely used for drilling mud cleaning, drilling cuttings treatment, oil sludge cleaning and other industrial waste water solids liquid separation.
Shale shaker, mud cleaner and decanter centrifuge is the major solids control equipments for drilling rig solids control system. Except for these equipments, we also produce vacuum degasser, shaker screens, centrifugal degasser, desander, desilter, mud agitator, mud gun, mixing hopper, vertical cuttings dryer, drilling waste decanter centrifuge, high G drying shaker, mud tanks and complete set of oil sludge treatment system, drilling waste management system, dewatering unit.

GN Solids Control Equipment and Vacuum Pumps for MENA client

One batch of vertical cuttings dryer, decanter centrifuge and vacuum pumps are ready for delivery for NEMA client.


The MENA region, encompassing key energy players such as Saudi Arabia, UAE, Kuwait, Egypt, and Algeria, requires equipment that can withstand extreme ambient temperatures and abrasive desert conditions. GN has confirmed that this specific batch has undergone rigorous factory acceptance testing (FAT) with an emphasis on:
Corrosion resistance for high-salinity formations.
High-temperature tolerance for hydraulic and lubrication systems.
The integrated system is designed to provide a closed-loop, zero-discharge solution for drilling fluid recovery and cuttings treatment. Here is a breakdown of the key components being delivered:
1. GN vertical cuttings dryer
Utilizing high-G force, this unit is engineered to recover valuable base oil or synthetic drilling fluids from OBM cuttings. By reducing the oil on cuttings content to less than 5% (by weight), the dryer not only saves significant fluid costs but also minimizes the environmental footprint of drilling operations—a critical factor for operators working in the sensitive desert and offshore environments of North Africa and the Middle East.


2. High speed decanter centrifuge
GN solids control is an OEM manufacturer of drilling fluids and drilling waste decanter centrifuge, we can produce high speed decanter centrifuge, middle speed decanter centrifuge, VFD decanter centrifuge, FHD decanter centrifuge. We can produce different bowl size decanter centrifuge, 9 inch, 14 inch, 18 inch, 22 inch, 30 inch. The discharged fluids from vertical cuttings dryer will be storage in catching tank, then the decanter centrifuge feed pump suck the fluids to decanter centrifuge for further treatment.


3. Vacuum pump
It is a 100% air operated vacuum pump for liquid ,slurry, and solids transfer. The pump can transfer material with high gravity and high density, with dry solids material or slurry with solids content max. up to 80%.
