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.

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.

Enclosure is a vital and major component of motor starters. Per jobsite situation, there are“Hazardous” and “Non-Hazardous” areas. Oil and gas drilling is appointed to Hazardous areas, it means the the possibility of the surrounding atmosphere being an explosive gas or dust mixture. Explosion proof is an mandatory demands for motors and motors starters where are used in the areas.

Like shale shaker, mud cleaner, decanter centrifuge, centrifugal pumps, mud agitators which are driving by electrical motors. They must be explosion proof while they are used in oil and gas drilling mud system. But if they are used in non-oil drilling mud system in safety areas, like water well drilling, horizontal directional drilling (HDD), piling, pipe jacking and other underground trenchless activies, they can be non explosion proof.

Many people may think EX standard motor and control panel have better protection than Non-Ex, especially for outdoor application. It is wrong. EX motor and control panel is only to ensure the products will not cause explosion in hazardous areas. It is IP protection rates which determines more the electrical products durability. The IP rating is set out in standard IEC EN 60529 and rates electrical enclosures by the level of ingress protection against solids (1st digit) and against liquids (2nd digit). The higher number for each digit, the better the protection against dust and liquid. GN Solids Control is using IP 55 EX motors in drilling mud processing system. And GN Solids Control electrical control systems are made with IP65.

Mostly, clients will directly say they need explosion proof zone 1 or zone 2 for their equipment. But sometimes, clients may say they want NEMA 7 enclosure.
