GN Separation Equipment Manufacturer

Recently, GN Separation successfully completed the manufacturing of two sets GNOST-15 Oil Sludge Treatment Systems (OSTS). The systems are currently undergoing rigorous factory trial assemblies to ensure optimal performance ahead of deployment.

A Comprehensive Solution for Oil Sludge Treatment
The GNOST-15 oil sludge treatment system comprises seven interconnected modules, each engineered to perform specialized functions that collectively transform toxic oil sludge into reusable resources. By addressing challenges such as high solid content, emulsified oils, and variable viscosity, the GNOST-15 ensures efficient separation of oil, water, and solids while minimizing operational costs and environmental impact.

1. Slurry Feed Pump Module: Precision Delivery for Uninterrupted Processing
At the first stage of the system lies the slurry feed pump module, responsible for transporting raw oil sludge into the treatment chain. Equipped with high-pressure, corrosion-resistant pumps, this module ensures consistent material flow even under harsh conditions.

2. Pre-Mixing Tank Module: Enhancing Separation through Intelligent Conditioning
Raw oil sludge often contains emulsified oils and dense solids that hinder direct separation. The pre-mixing tank module tackles this by diluting and conditioning the feed through controlled agitation, temperature adjustment, and chemical dosing. Here, steam generated by the integrated steam generator module heats the sludge to optimal temperatures (typically 60–80°C), breaking down viscous emulsions and improving fluidity. This step is critical for preparing the sludge for downstream processes, ensuring higher separation efficiency.

3. Shale Shaker Module: Eliminating Large Solids with Precision
To protect downstream equipment from damage and clogging, the shale shaker module removes coarse solids (>2 mm) using a high-frequency shale shaker. The shaker’s anti-splash cover and spray nozzles prevent material escape and ensure continuous operation without manual intervention. This module reduces the solid load on subsequent centrifuges, enhancing their longevity and performance.

4. GNLW-554 Two-Phase Decanter Centrifuge Module: Fine Solid Removal for Cleaner Output
The GNLW-554 two-phase decanter centrifuge is a cornerstone of the system, employing centrifugal force (up to 3,000 G) to separate fine solids from liquid phases. By introducing flocculants during operation, the module achieves exceptional solid removal rates (>95%), producing an oil-water mixture with less solids content. This step is pivotal for improving the efficiency of the final oil-water separation stage.

5. GNLWS-554 Three-Phase Centrifuge Module: Maximizing Oil Recovery
The GNLWS-554 three-phase centrifuge module represents the pinnacle of oil-water-solid separation technology. Using differential speed control and advanced bowl design, it efficiently segregates the incoming mixture into three streams: recovered oil, treated water, and residual solids. This module not only ensures compliance with environmental standards but also enables clients to reclaim valuable hydrocarbons, enhancing project profitability.

6. Chemical Dosing Module: Customized Formulations for Optimal Performance
Recognizing that oil sludge composition varies widely across industries, GN Separation’s chemical dosing unit allows for real-time adjustment of treatment parameters. Operators can prepare and inject demulsifiers, pH adjusters, and flocculants in precise concentrations via pumps.

7. Steam Generator Module: Energy-Efficient Heating for Enhanced Process Efficiency
Heating is a critical factor in breaking emulsions and reducing viscosity. The steam generator module produces clean, dry steam to heat the pre-mixing tank and maintain optimal process temperatures.

Factory Trials: Ensuring Reliability under Real-World Conditions
The two GNOST-15 systems are currently undergoing factory trials assembly at GN Separation’s facility in China. By combining robust engineering with modular design, the company offers scalable solutions tailored to diverse client needs. For more information, please feel free to contact us.
