As industrial and environmental regulations tighten, efficient oil sludge treatment has become a critical challenge for oil and gas companies. GN Solids Control, a global leader in solids-liquid separation technology, offers a highly effective Oil Sludge Treatment System designed to recover valuable oil, recycle water, and minimize solid waste. Our solution is widely used in oilfields, refineries, tank cleaning operations, and drilling waste management, ensuring a sustainable approach to sludge disposal.

The Working Process of GN Oil Sludge Treatment System
Our GN Oil Sludge Treatment System follows a structured, multi-stage separation process to extract oil, purify water, and manage solids efficiently:

Pre-Treatment & Chemical Washing – The sludge is first heated to 60-70°C, and chemical agents are introduced to break the oil-water-solid emulsion, making separation easier and more effective.
Solids Separation – The mixture then passes through a settling tank with an inclined plate clarifier, which allows larger solid particles to settle, reducing the burden on downstream separation equipment.
Three-Phase Decanter Centrifuge Separation – A high-speed decanter centrifuge is used to effectively separate the sludge into three distinct phases: recovered oil, clean water, and solid waste.
Final Treatment & Disposal – The recovered oil is clean enough for reuse or sale, the water can be recycled for further processing, and the solids, which contain less than 2% oil content, can be safely disposed of or treated further using biodegradation or thermal desorption.

Key Advantages of GN Oil Sludge Treatment System
High Separation Efficiency – Achieves an optimal separation of oil, water, and solids, maximizing oil recovery and minimizing waste.
Modular and Customizable Design – Configurable based on different sludge compositions and processing capacities, making it suitable for various industries.
Eco-Friendly & Regulatory Compliant – Reduces waste disposal costs and ensures compliance with environmental protection laws.
Cost-Effective & Low Maintenance – Designed for easy operation and low energy consumption, providing an economical solution for sludge treatment.
