A solidification unit or called solidification system is an efficient and economic solution for the treatment of drilling cuttings from both oil based mud and water based mud. Besides, it could also handle the sludge from some cuttings or waste pit. The principle is not so complicated, but the performance and continuous working ability are defining a solidification unit.

GN newest solidification unit ready for delivery

Since three years ago when GN Solids Control firstly designed and put into use the first set of GNGH Solidification unit, with the valuable feedbacks and experiences from both domestic China and abroad, GN improved the solidification unit several times. In a result, it is now more human oriented and easier to operate. This ready for delivery solidification unit is a newly designed one, and it would be its first show on client’s jobsite in a few days. It has following features comparing with previous design:


GN Solidification Unit System
1. It is more compact than before, with a smaller cuttings feeding hopper just above the coulter mixer the solidification unit itself are changed from two pieces into one piece. It is easier for transportation and later rig up on jobsite after transportation.
2. This new one is automatically controlled by a PLC control panel. All electrical components from brand Schneider, ABB or Siemens. Main operating data could be seen clearly on the screen and touching screen is easy for operators to control.
3. Mixing time could be controlled automatically and manually. Comparing with last model, this one is equipped with an electrical valve on discharge port of the unit, by using this, the operator could control the time period for the material to stay in the mixer for a better and adjustable mixing result.
4. Three VFD’s for the feeding. In this system, there are 3 feeding hoppers, all of which are VFD controlled by the control panel, then the fed proportion of chemicals, cement and cuttings could be adjusted according to the on time being conditions.
If you visit GN in recent days, you can check this system by yourself.

Based on the clients’ request in treating the drilling cuttings, GN continuously designed the vertical cuttings dryer for the solids discharged from the solids control system, and the decanter centrifuges application in the same system and also the high-G drying shaker and decanter centrifuge configurations. In the past year, GN designed and put into use a new solidification unit, which is specially for the final treatment of drilling cuttings from the water based mud.

solidification unit was firstly tested and used at a domestic jobsite, and with the valuable feedback from the client and end user, GN updated the design and enlarged the treating capacity by 50%, then it was used in an oversea jobsite by a world top oil serve company. The update was proved to be practical and the treating result was satisfactory. After that, GN updated the design again. Now the new design has better than last design in performance but the structure is more compact.

Besides the solidification unit, GN Solids Control’s products also covers:

  1. complete solids control line of drilling rig, including shale shaker, desander, desilter, mud cleaner, mud mixing unit, decanter centrifuge and all necessary pumps.
  2. waste management systems for the drilling cuttings like the vertical cuttings dryer, high-G drying shaker, decanter centrifuge and screw conveyors.
  3. solidification unit and TDU units, respectively for final treatment for water based mud and oil based mud.

4, dewatering unit and dewatering centrifuge for the treatment of drilling mud after recycled from the solids control system.

In all, GN Solids Control would like to provide a turn-key solution for your project in this field.

As the TOP drilling mud solids control and drilling cuttings waste management manufacturer and the 1st API certified solids control manufacturer in China, GN is always up to the pace of clients’ requests. Recently, GN has successfully designed and manufactured the solidification units for further treating the drilling cuttings from the forward hand waste management system.

Drilling cuttings solidification unit is also called drilling cuttings stabilization system, which is used after the waste management system, as further and final treatment of the drilling cuttings discharged from the solids control systems of the drilling rig system.

The complete procedure of complete zero-discharge line:

  1. a screw conveyor collects all drilling cuttings from solids control system of shale shaker, mud cleaner, desander, desilter and solids control centrifuge, and another screw conveyor transports the cuttings to the vertical cuttings dryer.
  2. after vertical cuttings dryer, solids discharge is collected and liquid discharge falls into a tank for being treated by high speed decanter centrifuge.
  3. then the cuttings from the vertical cuttings dryer and high speed decanter centrifuge now is of few liquid on them, they are nearly dry. They are ready to enter the solidification unit via waste collection hopper of solidification unit.

  4. cuttings from the hopper are transported to mixing chamber by a screw conveyor.
  5. cement and absorber are respectively kept in boxes and transported respectively to the mixer.

And beside the mixer, there are water feeding device and chemical feeding device.

  1. a high-shear mixer is used to mix all materials together, and after being mixed, the solids cuttings are safely and ready to be discharged.
  2. GN also has the further treatment for liquid phase discharged by the centrifuge of the waste management system or the solids control system, which is dewatering unit. The liquid discharged by dewatering unit is very clean and could go back to system. While the solids cuttings discharged by dewatering unit could also enter solidification unit for final discharge.
