Middle East is a mysterious and special place in the world, which contains the largest crude oil reservation. The importance of crude oil in modern industries brought Middle East countries wealth and high welfare. Like Dubai, it has developed from a desert port into one of financial centers of the world.
For the equipment related to the oil drilling and oil services, middle east companies only focus on the best quality ones. In field of oil and gas drilling solids control and drilling fluids separation, GN Solids Control is the 1st Chinese brand accepted by this market and also the No. 1 from China. Just recently, GN Solids Control just delivered a batch of equipment including following:

  1. vacuum degassers. Before the drilling fluids being treated by the desander and desilter cones, it still has lots of gas in it. This gas would reduce the efficiency of the centrifugal pump, and also cause some damage to the pump. A vacuum degasser could remove the gas from the drilling fluids, and unless the degasser from US or European manufacturers, GN Vacuum degasser is in no need of a large power pump. Meanwhile, it also services as a big agitator.
  2. Mud cleaners. Mud cleaner is a combination of desander cones, desilter cones and a underflow drying shaker. 2 centrifugal pumps are used for feeding for desander and desilter cones, the 10 inch desander cones are used for separating out particles larger than 40 microns, and 4 inch desilter cones are used for separating out particles larger than 20 microns. The solids discharged from cones fall onto the underflow shaker for drying.
  3. Centrifugal pumps are also one of GN’s core products. GN has full range of centrifugal pump models for solids control applications. All spare parts are interchangeable with Mission Magnum pumps, and pump impeller and casing are made of hard alloy.
    Welcome to contact GN for more information.

As the professional turn-key solution provider, GN Solids Control has provided mud recycling system and slurry separation system to many different applications including oil and gas solids control, drilling mud waste management, oily sludge separation, HDD, CBM and TBM.
All drilling or boring works are based on similar working procedure, as they all use a media for drilling, which is called drilling mud. And when the mud is out, it brings out a lot of drilling cuttings like sand and soil. An efficient mud separation unit can help to remove the cuttings to the most and save as much as drilling mud for future reuse. In order to achieve good goal for different applications, GN has designed and applied to different industries.

  1. For piling: for the piling works in cities, GN Solids Control has a series of compact desanding units for option. Those desanding unit are mainly equipped with a double deck shaker, with 2 steps separation: a lower deck shaker and a desander or desilter. And the optional capacities are 200GPM, 350GPM, 500GPM and 1000GPM. With a catch tank on below, it can be used continuously at piling site.
  2. For HDD: for the horizontal directional drillings, which are mostly for the pipeline laying work, GN has provided to market self-contained mud recycling units, fitted with shake shaker, desander and/or desilter and mud mixing unit and mud tanks with necessary storage volume.
  3. For TBM. For the big TBM projects, normally they need 3 steps separation: the shale shaker, desander cones and desilter cones. Recently, GN Solids Control designed a series of quite suitable system for such TBM projects, and before the shaker, for choosing out the big rocks and particles, GN designed a coarse shaker before the normal shakers, and in layout, it is quite compact for both transportation and operation.

What is a solidification unit? As its name, a solidification unit’s function is to reduce the moisture of some material, to get it dryer, or change it from liquid to solid. A GN Solidification unit is designed originally for the final treatment of drilling cuttings discharged from the vertical cuttings dryers and decanter centrifuges which are used for drilling cuttings separation.
Normally, the OBM drilling cuttings from a drilling cuttings vertical cuttings dryer is already quite dry, with oil on cutting only 0.5%. But still, it is not clean enough to be disposed, cause the cuttings then are still a little bit wet and with lots of active agent in it. A solidification unit’s function is to get the active agent into inactive, in order to allow the cuttings to be safely disposed. GN Solids Control has put the solidification unit into market for several years, and has sold it to both inside China and abroad.
GN Solidification Unit has following features:

  1. GN Solidification Unit is suitable for both oil based mud and water based mud cuttings.
  2. GN Solidification unit is easily operated by VFD controlled, easily to adjust the input capacity and chemical usage capacity.
  3. GN Solidification unit could work automatically and continuously.
  4. By using the solidification unit, the cuttings could be buried directly in most of jobsite, or being made into bricks for roads.
  5. Comparing with other solutions, the solidification unit is less expensive.
    Talking about other solutions, GN Solids Control, as a professional separation solution provider, has other solutions available, for example, the thermal desorption unit. And all above mentioned equipment used for such separation, as the shale shaker, mud cleaner, and solids control decanter centrifuge, and in a waste management system, for both cuttings treatment and fluids, there are vertical cuttings dryer, chemical dosing, oil water separation and inclined clarifier.

Decanter centrifuge is one of the most efficient equipment for physical separation. As long as the solids phase material are settleable (instead of floating on liquid surface), and they are of suitable particle sizes, they could be separated out by centrifugal force easily.

The decanter centrifuges are widely used for various applications, such as food industry, like the juice factory or jam factory, for the sugar plants, edible oil separation and etc. Waste water separation is one of the applications, too. Also the oil and gas industry, for the solids control system, barite recovery, drilling cuttings waste management and drilling fluids recovery, and also, for the refinery plants’ oily sludge separation, decanter centrifuges are playing an important role. In power plants, decanter centrifuges are also quite essential. Just recently, for only 1 client’s 1 order, GN has supplied 5 sets of decanter centrifuges which are to be used in a power plant.

There are several factors affecting the separation performance of a decanter centrifuge, and by adjusting the input data, a VFD centrifuge could achieve different separating goals. Normally, the larger bowl length-diameter ratio is, the dryer separated solids phase will be. GNLW454EY is a big bowl centrifuge with 18 inch bowl diameter and 4 of bowl length-diameter ratio. It is a quite ideal choice for power plant use. GNLW454EY also has a special cone angle and a high speed for such projects.

Based on different applications, GN Solids Control has designed a wide range of decanter centrifuges, more than solids control or waste management’s use. Like the bowl diameter, there are 9 inch bowl centrifuges, 14 inch bowl centrifuges, 18 inch bowl centrifuges, 22 inch bowl centrifuges and also as big as 30 inch bowl. For each bowl size, there are 2 or 3 optional length for different length-diamter ratio. And bowl material are of Duplex stainless steel like SS2304.
