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.

For any drilling work in China or in many other countries especially in more advanced companies, there are strict laws for drilling waste treatment after the drilling work. The treatment or management of drilling cuttings covers two topics, one is the recycling of useful materials, the drilling mud, to be reused into next project. And the solids phase, the cuttings should be separated out to the most and to be discharged safely.

GN Solids Control

The first system used with the drilling rig is solids control system, it contains main equipments including shale shaker, desander cones, desilter cones, mud cleaner and solids control centrifuge. It is called 4 levels of separation. After those above mentioned equipment, the drilling mud is clean enough to return back to the mud system and to be used into drilling again. It is the first closed loop.

But since the liquid phase as cleaned drilling mud returns to system, the cuttings should be discharged after some treatment, because in most countries according to the law, drilling cuttings are forbidden to be discharged directly because of damage to environment.

Besides solids control system, GN also provide the complete system until both the cuttings and drilling liquid are separated and transported to the place they should be. The drilling cuttings are firstly treated by a waste management system, containing equipments like high-G drying shaker GNZS594HGE-LD or vertical cuttings dryer GNCD930D as the 1st step of separation, and second step is decanter centrifuge GNLW363CG-VFD.

Later, secondly, the discharges are divided into 2 parts, liquid, enter back into the drilling system’s clean mud, and the solids, to be treated to the next system, GN Solidification unit, to stabilize the drilling cuttings and to discharge them safely. End of the solids phase.

And the liquid part, after being used as clean mud for several times, there may be small and extra fine particles in it. Then, using GNDU dewatering unit, the liquid part could be further treated and cleaned.

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.
