GN CBM Drilling Mud System

GN Solids Control successful delivery 2 sets of the  GNOST-15 Oil Sludge Treatment System to a key customer in Asia. This deployment underscores GN Solids Control‘s growing presence in providing effective environmental solutions for the region’s oil and gas sector.

 

Oil on Solids < 3%

Basic Sediment & Water (BS&W) in Recovered Oil < 3%

Treated Water suitable for reuse, promoting resource recovery and reducing environmental impact.

Each comprehensive GNOST-15 system supplied includes the following integrated modules:

Slurry Feed Pump Module

Pre-Mixing Tank Module

Shale Shaker Module

GNLW-554 Two-Phase Decanter Centrifuge Module: Offering a maximum processing capacity of 600 GPM (136 m³/h) and a maximum bowl speed of 3112 RPM for efficient solid-liquid separation.

GNLWS-554 Three-Phase Decanter Centrifuge Module: This core technology is specifically designed for Solid-Liquid-Liquid three-phase separation. Widely recognized in oil sludge treatment, the GN 3-phase decanter centrifuge is engineered for reliable, smooth operation. Key components include the driving system, decanter bowl, internal screw conveyor, cover box, skid, and VFD control panel. Effective separation requires the solid phase to be the heaviest, and the two liquid phases to have different densities. Crucially, the 3-phase decanter separates solids and separates the two distinct liquid phases (oil & water). Compared to 3-phase disc centrifuges, the decanter type is significantly easier to operate and maintain.

The demanding environments of African oilfields require robust, reliable, and efficient equipment, especially for handling challenging materials like drilling mud, sludge, and solids-laden waste. We are pleased to announce the supply of a batch of specialized Sludge Vacuum Pumps (also known as Solids Transfer Pumps) specifically designed to meet these rigorous needs.

What is a Sludge Vacuum Pump?

This advanced pneumatic vacuum pump is engineered for the tough job of transferring liquids, slurries, and – critically – dry solids. It stands out as a High Vacuum Loading Solids Transfer Pump, making it uniquely suited for harsh oilfield conditions where performance and minimal downtime are paramount.

Key Advantages for African Oilfield Operations:

High Vacuum Performance: Excels at loading and transferring difficult materials, including sticky sludge and dry solids.

Exceptional Solids Handling: Capable of transferring materials with high specific gravity and high density. Crucially, it handles slurries with solids content up to an impressive 80%.

Rugged & Reliable: Built to perform consistently in tough environments, minimizing operational disruptions.

Low Maintenance: Designed for simplicity and durability, reducing service requirements and operational costs – a vital factor in remote locations.

Versatile Transfer: Efficiently moves liquids, viscous slurries, and dry bulk solids using the power of vacuum.

Why This Pump is Ideal for Oilfield Sludge & Solids:

Traditional pumps often struggle with the abrasive, dense, and highly solid-laden materials common in oilfield waste streams (like tank bottoms, pit cleaning, and drill cuttings). The GNSP series Solids Vacuum Pump overcomes these challenges:

Handles High Solids Content: The ability to pump slurries with up to 80% solids content is a game-changer for efficient waste transfer and tank cleaning.

Dry Solids Capability: Easily transfers dry bulk materials like bentonite, barite, or dried drill cuttings.

Vacuum Loading: Simplifies the process of picking up material directly from sumps, tanks, or pits without complex priming systems.

Pneumatic Operation: Safe for use in potentially hazardous environments (no electric motors sparking) and requires only compressed air.

Reduced Clogging: Designed to minimize blockages when handling challenging solids mixtures.

This supply of GNSP series Solids Vacuum Pumps provides our African oilfield service client with a powerful, reliable, and low-maintenance solution for their critical sludge and solids transfer operations. By choosing this high-vacuum technology, they are equipping their teams to handle the toughest materials efficiently, ensuring smoother operations, reduced downtime, and lower maintenance burdens in the challenging African oilfield environment.
