Technical Advantages

Scalability: Modular tanks enable flexible configuration for varying drilling depths.

Environmental Compliance: Reduces waste mud volume by 30% through efficient solids control.

Reliability: Robust construction ensures uninterrupted operation in harsh drilling conditions.

 

Oil sludge, a by-product of the oil and gas industry, is a complex mixture of water, oil, and solid particles. Its proper treatment is

not only crucial for environmental compliance but also for resource recovery.

The GN Oil Sludge Treatment system is an integrated system designed to handle oil sludge efficiently. It comprises three main

modules:

Sludge Conveying Module: This module is responsible for transporting the sludge to the treatment area. It ensures a smooth and

continuous flow of material, setting the stage for effective processing.

Tank Cleaning Inclined Plate Clarifier Module:  The lamella plate is designed to separate oil and solid particles from the sludge

through sedimentation. This process helps in reducing the load on the subsequent treatment stages.

Three-Phase Decanter Centrifuge Module: The three-phase decanter centrifuge, is designed to achieve the ultimate goal of

separating oil, water, and solids. This advanced decanter centrifuge is capable of handling complex mixtures and extracting

valuable resources while minimizing waste.

The three-phase decanter centrifuge is designed to separate three distinct phases—solid, heavy liquid, and light liquid—based on

their different densities. This centrifuge operates on the principle of centrifugal force, which enables the separation of materials

with varying densities.

GN’s three-phase decanter centrifuges are available in different drum sizes, including 360mm, 450mm, and 550mm, to cater to

varying capacities and requirements. The design and functionality of the three-phase centrifuge are similar to that of a two-phase

centrifuge, with the primary difference being the discharge of the liquid phases. In a three-phase centrifuge, the heavy liquid phase

is discharged under pressure, while the light liquid phase is discharged without pressure.

Today, we focus on an innovative piece of equipment specifically designed for waste management companies in Africa: the GN

Vertical Cuttings Dryer and Centrifuge Unit. This equipment, with its outstanding performance and unique design, offers a new

perspective for handling drill cuttings from Oil-Based Mud (OBM) and Synthetic-Based Mud (SBM).

I. Designed for Drill Cuttings Processing

The GN Vertical Cuttings Dryer is specially engineered to handle drill cuttings from Oil-Based Mud (OBM) and Synthetic-Based Mud

(SBM). In the oil and gas extraction process, managing drill cuttings has always been a critical aspect of environmental protection

and resource recovery. Traditional methods often suffer from low efficiency and environmental pollution. The advent of this new

equipment marks a technological revolution in the industry.

II. Impressive Performance Specifications

At the core of this equipment is its remarkable performance. The cuttings dryer operates at a speed of 900 RPM, generating a

centrifugal force of up to 420 G. This allows for the efficient separation of liquids from drill cuttings, achieving rapid drying. Additionally,

the equipment is equipped with an optional Variable Frequency Drive (VFD) system, which enables users to adjust the speed according

to specific needs for optimal processing results.

III. Durable and Easy-to-Maintain Design

Every detail of the equipment has been meticulously crafted to ensure durability and ease of maintenance. The rotor blades are hard-faced

to a hardness level of HRC 65, which not only extends the equipment’s service life but also enhances its performance when dealing with

highly abrasive drill cuttings. Compared to competitors, this design significantly reduces maintenance costs and replacement frequency.

Moreover, both the blades and the rotor assembly have been individually balanced, which not only improves the stability of the equipment

during operation but also simplifies future maintenance and replacement. Users can replace the blades or rotor separately without having to

replace the entire assembly, saving both time and cost.

IV. Efficient Separation and Convenient Replacement

To achieve better separation results, the equipment features a specially designed high-precision stainless steel screen. This screen ensures

efficient separation of drill cuttings from liquids, while also offering a longer service life and easier replacement process. Unlike traditional

designs, the screen is separate from the frame. When replacement is needed, users can simply replace the screen without having to change

the entire frame, further reducing maintenance costs and operational complexity.

V. Automatic Cleaning and Comprehensive Flushing System

When dealing with high-viscosity mud and water-based mud, screen clogging is a common issue. To address this challenge, the GN Vertical

Cuttings Dryer is equipped with a special high-pressure air knife design that automatically cleans the screen, effectively preventing clogging.

Additionally, the equipment features a comprehensive flushing system with specially designed nozzles that thoroughly clean the liquid discharge

channels, ensuring the equipment maintains high efficiency even after long periods of operation.

VI. Significance for Waste Management in Africa

For waste management companies in Africa, the introduction of this Vertical Cuttings Dryer and Centrifuge Unit means not only more efficient

drill cuttings processing but also a step towards environmental sustainability. By reducing the liquid content in drill cuttings, lowering waste

disposal costs, and minimizing environmental pollution, this equipment sets a new benchmark for the waste management industry in Africa.

VII. Looking Ahead

As environmental awareness continues to grow and technology progresses, the waste management industry is facing unprecedented opportunities

and challenges. The launch of the GN Vertical Cuttings Dryer and Centrifuge Unit provides waste management companies in Africa with a powerful

tool to find the optimal balance between environmental protection and economic benefits. We look forward to seeing this equipment widely adopted

in the future, contributing to the global environmental cause.

On the path to environmental sustainability, every step counts. Let’s keep an eye on the development of these innovative technologies and work

together to create a greener and more sustainable future.
