GN Solids Control finished a package of oil base mud and cuttings treatment unit for an overseas client. The major separation equipped in the drilling waste management system is vertical cuttings dryer and high speed decanter centrifuge.

The vertical cuttings dryer model is GNCD930. GN Solids Control drilling waste Vertical Cutting Dryer applies centrifugal force to separate and recover oil based mud and cuttings, as well as synthetic base mud and cuttings.

The stainless steel screen basket with rotor assembly traps “wet” solids and accelerates them up 900RPM with G force to 420G. Usable drilling mud or oil slurry will be forced through the screen basket openings, and the oversize solids phase are extracted by the angled flights attached to the cone, which rotate slightly slower than the bowl. Tungsten carbide protects the scrapers from abrasive solids and ensures long operational life.

There is a gap with certain distance between the screen basket and rotor assembly, keep the accurate gap between them are essential for proper separation.

The decanter centrifuge model used in the drilling cuttings treatment system is 14inch, the model is GNLW363. It is the most popular size centrifuge model used in oil and gas drilling field. There are 2 decanter centrifuges used in the drilling waste management system. One centrifuge is used for drilling mud solids control, another decanter centrifuge is used after vertical cuttings dryer to further clean the recovered liquid phase. The 14inch decanter centrifuge design speed is 3900 rpm, and the typical bowl speed can up to 3600RPM. As the too fast speed request more frequency check and maintenance on the centrifuge. And if over 3200rpm, the high G force may damage the mud composite. But mostly when delivery from GN Solids Control factory, the max. Typical bowl speed is set up to 3200rpm.

The drilling cuttings treatment system is customized per client’s request. The vertical cuttings dryer and decanter centrifuges with accessory device are all allocated in a fabricated container for keeping temperature and for easy movement.

GN Solids Control makes full package oily sludge separation system for various types of oily sludge and oily waste. It can be used to treat oil sludge includes but not limited to oil sludge from Crude Oil tank cleaning sludge, oil sludge from Refinery plant waste oil sludge, and oil sludge from oil and gas drilling waste oil pit.

The most popular size Oil Sludge Treatment System made by GN Solids Control is GNOST-05 and GNOST-15. The related handling capacity is 5 m3/h and 15 m3/h. The handling capacity is specified by the decanter centrifuge and 3-phase tricanter centrifuge inside the separation system.

The principle of GN Solids Control Oil Sludge Treatment System is to use chemical to wash the oil sludge and with heating system to keep the temperature of internal materials 60 C degree to 70 C degree. The chemicals has maximum activities and can reach the best performance under the temperature 60 to 70 C degree.

After washing the oily slurry can be pumped to GN separation equipment to separate into oil, water and solids phase. The major separation equipment in GN oily separation system is shale shaker, decanter centrifuge and tricanter centrifuge. The shale shaker used in the oily sludge separation is a customized double deck shale shaker. There are jet nozzles around the the shaker deck for heating the oil sludge to keep it at a suitable temperate. On top of the double deck shale shaker, there are stainless steel anti-splash covers for protection the operators during system running.

The recovered water can be reused in the washing process inside the oil sludge separation system. After tricanter centrifuge separation, the BS&W inside recovered oil is with 2-3% (BS&W=Base Sediment & Waterin oil), it is clean enough for selling to the refinery companies. The discharged solids contain less than 2% oil which can be sent to biodegradation or thermal unit for final disposal if needed.

Clients need to note that, emulsified oil can only be treated after demulsification. If the oil sludge cannot be demulsified with demulsifier, the system cannot handle it.

GNCD930 vertical cuttings dryer is the major separation equipment which is used for drilling waste management. It is used to remove the particles below 3mm. GN Solids Control can offer 0.25mm, 0.35mm and 0.5mm opening screen basket to suit for various mud situation.

GN Solids Control vertical cuttings dryer is specially designed for OBL and SBM mud and cuttings. In some conditions, it can be used to treat WBM, but it is not applied for all WBM situation. High G drying shaker is the right equipment which is specially designed for WBM treatment.

Vertical cuttings dryer, as well as high G drying shaker, can reduce the liquid content in cuttings (WBM / OBM / SBM), to make the discharged cuttings comply with the requirement of environment protection; recover the valuable drilling mud and lower down the drilling cost. Generally, it can reduce the drilling waste, recover valuable drilling mud and reduce the cost for drilling.

During drilling, theoretically speaking, about 1 ~ 4 barrels drilling fluids can be recycled from each barrel of drilling cuttings removed by solids control equipment. Theoretically speaking, GN drilling cuttings dryer system consisting of Vertical cuttings Dryer could recycle about 1 barrel drilling fluids from 3 barrels drilling cuttings.

Besides vertical cuttings dryer, GN Solids Control make full line drilling mud and drilling waste management equipment.

Solids Control shale shaker which are used in offshore platform drilling rigs are different with onshore drilling rig equipment. Mostly, the jobsite may have special request on the explosion proof standard and on the lifting certificate.

It’s up to the rig request and the rig type. Some need marine explosion proof standard for motors and electrical control system, and special lifting certificate, some rigs do not need. Clients should specify their special request to suppliers before orders.

There are different types of explosion proof standard for various market. The most popular EX standard are CNEX, IECEX, ATEX, and UL.

CNEX is China National Standard for explosion proof. All EX motors and electrical components must be complied with CNEX standard.

IECEX is International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres. All EX components made in China, if they complied with IECEX standard, they first be complied with CNEX. It means there will be 2 EX marks on the products.

ATEX is ATmospheres EXplosibles. It is European standard. The same as IECEX, all EX products made in China, if it is complied with ATEX, it is also complied with CNEX.

Seen from above, you may know, standard and products for CNEX, IECEX and ATEX are nearly the same. They just have different Quality control system to get the certificate.

UL is Underwriter LaboratoriesInc, it is the national explosion proof standard in USA and Canada only. If some thing said complied with UL standard, mostly probably, it is made in USA.

The design and technical requirement of UL is different with CNEX, IECEX or ATEX. It means the motors made per CNEX, IECEX and ATEX are all interchangeable while with the same frame code. But UL standard motors cannot be interchangeable with them. So UL is fewly used outside USA or Canada.
