With environmental regulations tightening across the globe, oilfield service companies are under increased pressure to manage drilling and refinery waste in an efficient and eco-friendly way. Recognizing this demand, GN Solids Control has recently completed the delivery of two complete sets of GNOST-15 Oil Sludge Treatment Systems to a prominent environmental solutions company in Asia.
These modular systems are designed to recover oil, reduce waste volume, and meet discharge standards — all while lowering operational costs and environmental impact.
A Turnkey Solution for Oil Sludge Recovery
The GNOST-15 is a fully integrated system engineered to treat challenging oily sludge composed of oil, water, and fine solids. Each system includes:
Feeding Pump Module
This delivers a controlled feed of sludge into the system using a heavy-duty progressive cavity pump, ensuring stable flow and pressure throughout.
Premixing Tank Module
The sludge is heated and mixed with water and chemicals to reduce viscosity and prepare it for further separation, improving overall treatment efficiency.
High-G Shale Shaker Module
The first stage of physical separation removes larger solid particles and debris to protect downstream equipment.
Two-Phase Decanter Centrifuge (GNLW554)
Handles separation of fine solids and liquids, reducing TSS (total suspended solids) to manageable levels.
Three-Phase Decanter Centrifuge (GNLWS554)
Performs the crucial task of separating recovered oil, water, and residual solids in a single step, improving oil recovery and reducing disposal volume.
Chemical Dosing System
Ensures optimal demulsification and flocculation for efficient separation. The system is fully automated for precise dosage control.
Steam Generator
Provides thermal energy essential for lowering sludge viscosity and enhancing chemical reaction effectiveness.
Sustainability and Performance Combined
The GNOST-15 system demonstrates a holistic approach to oily waste management:
Oil Recovery: The system achieves a recovered oil quality with BS&W below 3%, enabling the oil to be reused or sold.
Cost Reduction: Recovered oil and water can be reused, significantly reducing the cost of fresh materials and disposal.
Regulatory Compliance: The system ensures that treated effluent and solids meet local environmental discharge standards.
Space-Saving Modular Design: All modules are skid-mounted and containerized, offering easy transport and installation at remote or compact sites.
GN Solids Control – Advancing Environmental Responsibility in Energy Sectors
This successful project reinforces GN’s commitment to supporting clients in Asia and around the world with advanced, practical, and environmentally responsible waste treatment technologies. From oil sludge treatment to solids control, GN continues to offer reliable solutions that improve both economic performance and environmental outcomes.
