The Featuers of GN Vacuum Degasser and Mud Gas Separator

In the dynamic world of oil and gas drilling, efficient mud gas separation is a paramount concern. GN Supplies two indispensable tools in this process are the Vacuum Degasser and the Mud Gas Separator These unsung equipment work tirelessly to maintain drilling fluid integrity, ensuring a smooth and safe drilling operation. Let’s dive into the intricacies of these essential components and explore how they contribute to the success of drilling ventures.

At the heart of every well-maintained drilling fluid system lies the Vacuum Degasser. And the most welcomed model is GNZCQ360B operates under reduced pressure conditions, creating a vacuum that facilitates the removal of entrapped gases such as methane, carbon dioxide, and hydrogen sulfide. Its compact design and high efficiency make it a valuable asset in maintaining the stability of the drilling fluid and ensuring the safety of the drilling operation. By efficiently expelling these undesirable elements, the vacuum degasser prevents issues like kicks, blowouts, and other hazardous conditions. This will protect the other separating equipment like pumps and centrifuges.

In the rugged landscapes of drilling sites, the Mud Gas Separator stands as a robust and dependable guardian against gas intrusion. This degasser, also known as an atmospheric degasser, utilizes a simple design to remove entrained gases from drilling fluids. Unlike its vacuum counterpart, the MGS operates at atmospheric pressure, making it a cost-effective solution for those who prioritize simplicity without compromising performance. It is installed far from the drilling mud tanks and the mud pumped from the drilling pit and entered the MGS, separated most of hazadous gas, and ignited by another device.

The MGS is usually red because it is a fire protection equipment. GN supply the ATEX certificate to meet specific requirements. The most welcomed model is GNZYQ1000. Here is the specs:

Model GNZYQ1000A
Tank diameter 1000mm
Capacity 200~280m3/h
Inlet 4 Inch
Output 10 Inch
Vent Line 8 Inch
Weight 2234Kg
Dimension: L×W×H 2265×2000×5681mm
The above specification and parameters for reference only.

Also some clients need more capacity, and then we also recommend GNZYQ1200. If you are interested in GN Mud Gas Separator, as well as GN Vacuum Degasser. Please feel free to contact me at  for more information.

I recommend GNZS 706 Double Deck Shale Shaker for Water Based Mud Treatment

Today, I am excited to introduce the shale shakers, a crucial component in the realm of WBM treatment. While we may not provide steamers or heating systems, our focus lies in delivering top-notch pipelines for heating systems that seamlessly connect to shale shakers.

Shale shakers play a pivotal role in the oil and gas industry, specifically in the initial phase of the solids control process. They serve as the first line of defense against unwanted solids and debris, ensuring the efficiency and longevity of downstream equipment. At GN Solids Control, we take pride in our innovative approach to enhancing the functionality of shale shakers.

One of the challenges faced in the prolonged use of shale shakers is the potential blockage of screens. To address this, GN has ingeniously incorporated spraying nozzles designed to flush the screens after extended operation periods. Additionally, our anti-spraying covers are strategically placed to contain sludge splashes, maintaining a clean and hazard-free working environment. Have you considered the benefits of these covers and spraying nozzles for your shale shakers?


GN Solids Control offers two range of shale shakers here, including both single-deck GNZS594 and double-deck GNZS706. These shakers are designed to excel in various work sites, with double-deck shakers proving particularly effective in both WBM and oil sludge treatment projects. GNZS706 series double deck shaker, which screen size up:750×900mm/down:700×1250mm and the capacity is 140m3/h(616GPM), is properly designed for piling, TBM, big oil gas rig, big trench-less project, or the industry separation for multi- phase separation.


Besides, GN makes and supplies a series of equipment including the centrifugal pump as a feed pump for the shale shaker, and the desander and desilter are also important for better treatment of mud. For further separation of the mud. A centrifuge is important, and I shared more information about hydraulic drive centrifuges in another blog.

As we navigate the intricate landscape of oilfield operations, the role of shale shakers becomes increasingly prominent. GN Solids Control is committed to providing cutting-edge solutions that enhance the performance and reliability of your operations. We look forward to your response, eagerly anticipate the opportunity to contribute to the success of your endeavors.

A Brief Guide to GN Vertical Cutting Dryer Installation and Operation

When it comes to drilling operations, especially using OBM as drilling mud, efficiency and safety are paramount. One essential piece of equipment in this industry is the GN Vertical Cutting Dryer. Proper installation and operation of this device can significantly impact your operations’ success. In this blog, we’ll take you through the essential steps to ensure you get the most out of your GN Vertical Cutting Dryer.

Preparation Before Starting:

  1. Initial Installation and Adjustment: Before the first-time use, reinstalling, or resuming operation, ensure the equipment is installed and adjusted correctly.  Take the time to inspect and make necessary adjustments for optimal performance.
  2. Read the Manuals: Knowledge is power. Familiarize yourself with the user manual and the electric control operation instructions attached to the electric control cabinet. These documents hold the key to smooth operation.
  3. Daily Startup Preparation and Inspection:
    • Clean the Environment: Start by clearing the area around the site, ensuring there are no unnecessary tools, parts, or debris near the dryer. A clutter-free workspace is a safe workspace.
    • Belt Tension: Check the tension of the belt to guarantee it’s correctly aligned and functioning.
    • Observation Holes: Take a peek through the upper and lower cylinder observation holes. Ensure no drill cuttings, mud, or foreign objects obstruct the machine. Always start the dryer with no load; this protects the equipment and keeps operators safe.
    • Check Components: Inspect critical components such as the drive cover, upper and lower cylinders, and observation hole covers for secure installation. Double-check screws in rotating parts, inlet/outlet pipelines, and the control cabinet to ensure they aren’t loose.
    • Fluid Supplies: Make sure you have a clean water supply and a reliable source of compressed air for the flushing pipeline.
    • Jog Start: Begin the dryer using the jog function. Keep an eye out for any abnormal vibrations or clashes during this initial stage.

Start and Stop Procedures


  1. Open the air valve of the air knife (if applicable) and turn on the main power supply.
  2. Start the oil pump motor and verify that oil pressure is within normal parameters.
  3. Initiate the solids discharge screw conveyor for the vertical cuttings dryer.
  4. Start the main motor after confirming proper lubricating oil return.
  5. Activate the flushing pump based on the liquid phase’s fluidity (timed or continuous, as required).
  6. Once the equipment operates stably, open the air knife valve and start the feeding screw conveyor. Make sure the feed is stable and uniform to prevent additional vibrations. Keep a close eye on the main motor’s current to prevent overloading.


  1. Halt the feeding screw conveyor for the vertical cuttings dryer.
  2. Open the flushing pump and air knife valve to flush the slurry outlet channel and screen basket for at least 10 minutes.
  3. Stop the main motor.
  4. Turn off the oil pump motor.
  5. Bring the solids discharge screw conveyor to a stop.
  6. Turn off the main power supply and the air source.

Placement of VFD Control Panel (if available):

  • For convenient operation, it’s essential to position the VFD panel within 5 meters (ideally) but no more than 10 meters from the unit. An added rainproof awning ensures smooth operation even in inclement weather.

Cable Specifications:

  • The user should ensure the preparation of cables of the appropriate length, connecting them to the main motor, auxiliary motor, oil pump motor, flushing pump motor, and power supply.
  • Meeting the specified cable standards is crucial.

By following these steps, you can ensure the safe and efficient performance of your GN Vertical Cutting Dryer. Efficiency and safety go hand in hand, and the proper operation of this equipment can make a significant difference in the success of your drilling operations.
