There are many different standards for explosion proof certificate for motors, control panels and electrical components (VFD drives, EX air conditioner, cable gland, socket and plug, etc…). Many clients do not know the difference and they do not know how to choose the right standard for the project.
Below is the most popular EX standard we mostly know:
1) CNEX is China National Explosion Proof standard; this can be used in China and many other countries. CNEX is an approved certifying body according to IECEx which is the leading authority in the world for ensuring standards are met and maintained. CNEX are registered as a ‘Certification Body’ (CB) by IECEx and they are authorized to certify and put their mark on equipment.
Except USA, Europe and Australia, most of the countries include Middle East countries and Africa countries they accept CNEX. We have sold our CNEX equipment to Oman Kuwait Qatar UAE , Iraq. You can learn more about CNEX standard here:
http://www.china-ex.com/english/aboutcnex.html
2) ATEX is a Europe explosion proof standard. It can also be used in many other countries out of Europe. But ATEX is normally not accepted in Australia, USA etc.
3) IECEX is International Electrotechnical Commission Explosive standard. But many Europe countries clients do not accept IECEX. They only accept ATEX. You can learn more about IECEX standard here:
http://iecex.com/information/about-iecex/
And there are many other explosion proof standards especially for certain countries, like TP TC certificate for Russia. UL standard for America, but UL is also accepted in some other countries.
However, the standard selection is also depending on the end user and the third party for inspection. Even in the same country, different end user has different standard. Or even for the same end user for different project, they have different standard. Like KOC only accept IEC for deep drilling, but for workover rigs, or small rigs, other EX standards maybe accepted.
So clients who intend to order equipment for hazardous areas need to make choice depending on the end users who they are dealing with, and what the end user want.
For the same model motors from the same suppliers, maybe it complies with ATEX certificate, CNEX certificate, and IECEX certificate, and UL certificate. Even the model and product is the same. If the requested certificate standard is different, the prices are different, and nameplate is different, and QA/QC documents record in the manufacturing company are different. And the nameplate cannot be changed after delivery from the OEM factory. It is not allowed by the Certification Body. Otherwise, the certificate will be canceled.

GN Solids Control makes decanter centrifuge for slope oil treatment. Following is the slope oil need to be treated from a client:
The material is Slope Oil which after keeping for 2 days, the net weight of it becomes 0.98%.
At Phase 1: (at the top), The oil in the Raw Material becomes around 30 to 40%
Phase 2: (in the middle), 40 to 50% becomes water.
Phase 3: ( at the bottom), Crude oil sludge is around 10 to 20%
Density:
In the slope oil Water Density: 1.000
in the slope oil the Oil Density: 0.945
Please Note: after the tests, we found out that the Emulation sample has also 2 parts
Density of Emulation Sample:
Phase 1: 0.995
Phase 2 (Sludge sample): 1.007
We are familiar with the Decanter Centrifuge therefore we don’t need any details about it, but please can you give us an estimate price for this. We are bidding in a Contract and it is very important to have the price as soon as possible.
BTW, the decanter centrifuge capacity needs to be 2000 L/H.
GN Solids Control Solutions are as following:
Depends on different oil slopes, we have options of different decanter centrifuge available for clients. For above capacity.2000L/H, GNLW364D-VFD decanter centrifuge can be used. And after solids and liquid separation, the slope can be sent to a 3 phase disc centrifuge. The dis centrifuge can separated the flow into oil water and solids.
If there is coarse solids in the slope oil, some times before sent to the decanter centrifuge for treatment, a shale shaker will be used to screen out the coarse solids in order to protect the centrifuges.
Besides the oil slope treatment, GN decanter centrifuge are widely used in many other industry for solids and liquid separation. This include oil sludge treatment, drilling mud solids control, water treatment, mining slurry treatment.

Recently, GN Solids Control launched the new products: ViST Vacuum Shale Shaker Screen Technology. ViST is Vacuum Screen Technology which is to work with shale shaker to reduce drilling waste and recovery usable drilling fluids. ViST technology is was a pending patent design developed by GN Solids Control from June, 2017. Before launching to the market, GN Solids Control took factory test and jobsites test to ensure its performance. It proved to be very efficient for recycling drilling fluids.
The ViST Pan is installed under the last screen or mounted externally. And a suction hose is connected to ViST vacuum unit. The compressed air from air compressor or the rig air supply is required to create suction on the last screen surface, pulling additional fluid off the cuttings. It can reduce the liquid on the drilling cuttings by 30-50%. GN ViST Vacuum Shale Shaker Screen Technology can suits for different shale shaker models, and a set of ViST Vacuum Shale Shaker Screen unit can cover 2 or 3 shale shakers.
The ViST Vacuum Shale Shaker Screen Technology can be used under shale shaker screens to further drying the cuttings, and recovery more usable drilling fluids. It can be used as a replacement of High G drying shaker. Compared with High G drying shale shaker, the ViST Vacuum Shale Shaker Screen Technology only consume air, there is no electrical parts. In this case, the ViST Vacuum Shale Shaker Screen Technology is a perfect choice for offshore drilling and for hazardous areas. And there is no shaker screen consumption. The operation cost is low.
GN Solids Control developed this technology pushed by some clients. They have the request for projects, but they cannot buy it in the market. GN Solids Control owns his own Research and Development department (R&D). Till now GN Solids Control developed over 20 patents, which are already approved. Some new patent application is under process. That is the reason clients pushed GN to do the research, They believed that GN Solids Control are capacity to do it. And GN did it.

This week, a big quantity of vacuum slurry transfer pump unit has been ready for shipment. The big quantity of vacuum slurry transfer pump unit is prepared for a big project in Beijing for big capacity material and for long distance transfer.
GN vacuum slurry transfer pump is also named as waste vacuum pump, or solids transfer pump. It is a 100% air driven slurry transfer vacuum pump for liquid, slurry, and solids transfer. GN vacuum slurry transfer pump is with a special structure design, it can be used at tough environmental for high solids content and big solids size transfer. The vacuum slurry pump is with the features of high working performance and less maintenance. The vacuum slurry pump can be used to transfer material with high gravity and high density, solids content max. up to 80%. Another advanced feature is that GN vacuum pump can be used for long distance transfer. The max design transfer length can up to 1000m.
The client is looking for transferring units to suit for long distance material transfer for a long time. Once they met GN Solids Control on Beijing CIPPE oil and saw the jobsite video of GN vacuum slurry transfer pumps, they are surprised by the wide application range and the up to 1km away transfer distance. As they did not use the vacuum slurry transfer pump, in order to confirm that GN vacuum slurry transfer pump can suit for their application, they rent a pump for trial. After jobsite test, they are confident with GN vacuum slurry transfer pump and confirmed the order to GN.
In the first order, they requested 8 units vacuum slurry transfer pump. Every 4 vacuum slurry pump units are fixed inside a modified 20ft container for easy movement and good protection. All inlet pipes, outlets pipes and air feeding pipes are fixed well on the modified container.
Besides vacuum slurry pump, GN Solids Control can make other full line equipment for mud solids control and drilling waste management, such as shale shaker, mud cleaner, decanter centrifuge, shake r screens, etc….
