As more and more governments issued more and more strict regulations on the envornment protection, drilling waste management equipment becomes more and more necessary at drilling rig site, especially at oil and gas drilling rig site. As the drilling fluids contents various kind of chemicals, if discharged directly. it will have very bad pollution to the environment.

GN Solids Control latest design drilling waste management equipment drill cuttings solidification unit are welcomed at jobsite.

1) The drill cuttings solidification unit can be used to treat drilling cuttings discharged from the high G drying shaker. When the cuttings from solids control shale shaker, desander, desilter treated by high G drying shaker, the fluids will go to drying shaker catch tank for further treatment, the solids from high G drying shaker can be treated by drill cuttings solidification unit.

2) The drill cuttings solidification unit can be used to treat drilling cuttings discharged from decanter centrifuge. The liquid phase will be covered by further treatment, like dewatering unit. while the solids phase can be treated by drill cuttings solidification unit.

3) The solids discharged from vertical cuttings dryer can be further treated by drill cuttings solidification unit. It can reduce the water content in the waste.

Many clients may wonder, what is the water content after the drillings treated by drill cuttings solidification unit? It is not easy to see what the water content is. As it is flexiable. It is controlled by the operators. If you want to make the cuttings dryer, you add more chemicals, if you do not need very dryer, you can reduce the quality of chemical.

Features of GN latest design drill cuttings solidification unit

1) Small footprint with high efficiency of GN latest design drill cuttings solidification unit.

2) Automatically control of GN latest design drill cuttings solidification unit.

3) All the screw conveyers of GN latest design drill cuttings solidification unit are variable speed control.

GN dispatched over 30 sets high speed and low speed decanter centrifuges for an Algeria projects in the beginning of year 2015. Till now the centrifuges are running nearly 1 year. The clients are happy with the performance and highly commended with GN centrifuge performance and GN people services.

All the centrifuges are the model GNLW363CG. GN C class decanter centrifuges is the 3^rd generation. It is the latest design from GN Solids Control company. All the centrifuges are equipped at jobsite for mud solids control and drilling waste management. They are used to recovery barite from drilling fluids in solids control system. And in the waste management system, they are running in high speed to separate the fine solids and reduce the weight of the mud.

Based on the latest and advanced design of GN Solids Control decanter centrifuge, the centrifuges for Algeria project are capable with below features after some value-additional design.

1) All the centrifuges are fixed speed control. But the operators can change speed through changing pulley and belt. All the centrifuges have 4 speeds for optional: 3200rpm, 2800rpm, 1800rpm, 1600 rpm.

2) There are temperature senses for the main bearings at both ends. Then bearing temperature can display on the electrical control screen. The operators can set up the max. temperature allowed for the centrifuge bearings, then when it is over heat, the centrifuge will shut down to protect the machine.

3) The explosion proof control panel are made from high quality aluminum. The lifetime is long. And it is with a better performance for sealing. And also the appearance is nice.

4) The screw protection for the centrifuge is interchangeable tungsten carbon tile. It is much more reliable than the normal way hard surface welding.

Besides above point, the GNLW363CG new design decanter centrifuges are with below features:

1) It is more user friendly.

2) The performance is more reliable.

3) It is more east for operation and maintenance.

4) The lifetime is longer as it is made from upgrade material.

As worldwide famous manufacturer on oil field mud solids control equipment and drilling cuttings waste management equipment. GN Solids Control advanced design decanter centrifuges earned a good name worldwide. All control system for the centrifuges are design and made by GN own engineering team.

Positive pressurized control panel for variable speed frequency control are mostly equipped for GN high quality waste decanter centrifuge and vertical cuttings dryer. The explosion proof enclosure is made from anti abrasive stainless. Inside components of GN Positive pressurized control panel are all chosen from international famous brand: Schneider, Siemens, ABB, etc…

Positive pressurized control panel is a light point of GN. It is not only for start and stop of the equipment. But also, GN giant engineering team developed his own programmer with PLC for smart control. The PLC control panel for VFD centrifuge is not only control the main motor and back motor of the centrifuge; it does also control the pump and offer a variable speed.

As most GN equipment need to equip electrical control panel, and all clients eagerly request high quality explosion proof control system with processional design, good price and short delivery time. GN Solids Control developed his electrical control department and make high quality explosion proof control panel, complete electrical control system and junction box only only for GN equipment, but also for different applications. GN Solids Control is certified manufacturer of explosion proof control systems.

Flame proof is the most common type for explosion proof control panels. It can be applied for mud agitator, centrifugal pump, shale shaker, mud cleaner, mixing unit, oil and gas drilling mud solids control system, HDD / CBM mud recycling system, no dig desanding plant, fixed speed or variable speed for screw conveyer, and other applications.

The enclosure of GN flame proof type Explosion proof control panels are made out from high quality abrasive resistant Aluminum. It is with nice appearance, better sealing performance and light weight. It suits China National Explosion Proof (CNEx) standard. The protection level of GN standard Ex control panel is IP56, and suits for Class 1 Division 1, group C and D.

If you have any questions regarding explosion proof control panel or system, welcome you contact GN Solids Control freely.

In nowadays, a complete oil and gas drilling rig should be equipped at least 2 mud systems: One called solids control system for drilling fluids treatment; another system called the pitless mud system for drill cuttings treatment.

Many clients are wondering, if the pitless mud system for drill cuttings system can replace the shaker tank system or not?

Firstly, we have a draft idea about the 2 mud systems.

Solids Control system for drilling fluids treatment

Complete solids control system can be composed of 4-stage solids control equipment or 5 stage solids control separation process.

The 1rst stage solids control equipment: shale shaker. It is used to remove the coarse particles from the drilling fluids.

The 2^nd stage solids control equipment: Desander, it utilizes 10’’ hydrocyclone cones to remove particles above 47 microns.

The 3^rd stage solids control equipment: Desilter, it utilizes 4’’ hydrocyclone cones to remove particles above 27 microns.

The 4^th stage solids separation equipment: Decanter centrifuge. It utilizes centrifugal force to remove the fine solids to 2 ~ 5 micron. Middle speed decanter centrifuge is normally used this stage to recovery the barite.

The 4 stages solids control equipment composed of 4 stage separation. Another separation is for vacuum degasser. It is used after shale shaker and before desander desilter.

Clients chose the suitable separation machine per rig condition.

As the mud pit is forbidden in China at the rig site, pitless mud system for drill cuttings treatment are more and more equiped.

1) High G drying shaker, it is normally used to treat water base drill cuttings.

2) Vertical cuttings dryer. It is used to treat oil base drill cuttings.

3) High speed decanter centrifuge will be used after high G drying shaker or vertical cuttings dryer to separate the fine solids

4) Dewatering unit. If there are many ultra fine solids cannot be removed by centrifuge directly. Dewatering unit for chemical dosing will be used.
