The GNZS595J-SHBJ linear motion shale shaker with drilling fluids flow rate approx. 140m3/h ( 616gpm), the flow rate is for reference only, it will be different based on different API No. of shaker screens. it is drived by 2ea of 1.72KW vibration motor, the max vibration G force is up to 7.5G, the shaker screen is 5pcs of 585x1165mm, total screen area is 3.4m2, the deck angle adjustable range is -1° ~ +5°, the feeding method is back feeding box by receiving drilling fluids from drilling rig to its possum belly then flow to shaker buffer box. We have CNEX, IEC EX, ATEX for option based on client’s requirement.

The ViST vacuum screen technology is utilized to work with shale shaker to reduce drilling waste and recycle more useful drilling fluids, it can be widely used for OBM, SOBM, WBM and for both onshore and offshore applications. A good ViST vacuum screen can reduce waste by 30~50% effectively, for less cost of drilling waste transportation, storage and waste treatment.
The catch pan is installed under the last screen panel by connecting with the vacuum unit, it could be 100% air operated or electric for your option. One ViST vacuum unit can be connected to 2~3 shakers with only one air supply to the ViST vacuum unit. Each electric vacuum unit is for one unit shaker only.
The 3 units of single shale shaker are installed on one triple shaker skid for convenient movement and installation, one set of possum belly is designed for these three units of shale shaker.

GN Solids Control Equipment on 2023 CIPPE Beijing Oil Show

This week GN Solids Control participate in 2023 CIPPE Beijing oil show with our lastest technology and equipments. We met with our domestic clients also international clients who is interested in GN technology and equipments. After the exhibition, some of the clients visit our facility to check our workshop and equipments.

What equipments we had showed at CIPPE 2023?
ViST vacuum shaker, GN updated version vacuum shaker with electric drived air compressor to supply air to the vacuum unit, a catch pan is installed under the last panel screen which is connected with air compressor. The features of GN vacuum shaker is pulse type negative pressure to provide better vacuum and avoid blocking the shaker screen.
Big Bowl decanter centrifuge can be used for high volume slurry cleaning, mud dewatering with chemical dosing unit, oil sludge separation system, low gravity solids separation from the drilling fluids and drilling waste treatment.

3 phase disc separator, it is used to separate oil water and solids from the oil sludge, to get the clean oil and water. It is normally used after 2 phase decanter centrifuge, to reduce the solids content and separate the big solids which is bigger than 0.5mm. GN designed oil sludge treatment system with proper arrangement of 3 phase disc separator with its flushing tank, operation water tank, solids discharge unit and feeding pump.

The 3 phase decanter centrifuge is a horizontal type 3 phase centrifuge to separate oil, water and solids. If the requirement of recovery oil and water is not in high level, we can use 3 phase decanter centrifuge instead of 2 phase decanter centrifuge and 3 phase disc separator.

GN Solids America Attend 2023 Offshore Technology Conference (OTC) in Houston

Celebrating 50 years since 1969, OTC’s flagship conference is held annually at NRG Park (formerly Reliant Park) in Houston. OTC has expanded technically and globally with OTC Brasil and OTC Asia.

This week GN Solids America ( Branch of GN solids control) attend 2023 Offshore Technology Conference (OTC) in Houston successfully. More than 1,300 companies from 104 countries showed their technologies and equipment on the exhibition floor, spanning more than 276,000 square feet, and more than 31,000 participants visit OTC 2023.
The products we showed at OTC 2023 are as below:

  1. The 2nd generation vacuum shale shaker, the vacuum screen technology is introduced to recycle fluids and reduce waste. The catch pan is installed under the last screen panel of drilling fluids shale shaker, maximumly 1 unit of vacuum screen can be connected for 3 units of shale shaker. Extra vacuum unit with air source, a suction hose is connected to ViST vacuum unit, the compressed air or rig air supply to crease suction on the last screen top, pulling additional fluids off the drilling cuttings, it can reduce the fluids from the cuttings by 30% to 50%.
  2. Drilling fluids decanter centrifuge, GN produce both 2 phase decanter centrifuge for solids liquid separation and 3 phase decanter centrifuge for solids oil water separation. For drilling fluids decanter centrifuge, we produce 9 inch, 14 inch, 18 inch, 22 inch, 30 inch decanter centrifuge with different speed, which can be applied for drilling fluids treatment, drilling waste treatment, oil sludge treatment, industrial waste water treatment and dewatering centrifuge.
  3. Portable solids vacuum pump
  4. Drilling fluids shale shaker screen with different dimension
    You are welcomed to visit us to check the solids control equipments and shaker screens in GN Solids America (30,000SF) warehouse located at 6710 Windfern Road, Houston, TX 77040, USA.

New Type J Version Solids Control Shale Shaker for Overseas Client
