Oil Sludge Treatment, project for ass covering. It is normally existbeside the rigs, or the oil production plants, a big pit, with all the oily sludge left, so solids oil water mixed together, without any function to reuse anything. Then that is where oil sludge treatment system needed. GNOST1, GNOST5, GNOST15 is so far 3 standarized model, which may hopefully meet most of the requirement.

Sludges that contain oil and water are generated through a variety of activities and processes on board ships, including sedimentation in tanks, tank dewatering processes, and leaks or cleaning cycles in backflush filters and separators for treating fuel oil and lube oil. The trend for combusting high density fuel oils of higher viscosity, as well as the use of residues as a fuel for medium­speed diesel engines, also increases the production of sludge from both fuel oil and lube oil.Emergence of sludges containing oil and water The build up of these oil and water­containing sludges represents a considerable disposal problem.

Though many options can be implied, GN utilize the standard separation equipment to do the work, which also make sense, it is for separation, the key equipment would be decanter centrifuge,  shakers, plus disc stac separators. GN Oil Sludge Treatment System is to use chemical to wash the oil sludge with heat to temperature of 60-70 C degree. After washing the slurry is pumped to GN separation equipment to separate into oil, water and solids. The recycled water can be reused in the washing process, and the oil is clean enough to sell to the refinery company, the solids contain oil between 2%-5% which can be sent to biodegradation or thermal unit for final disposal.

After commissioning projects to a ship for COSL, the after sales engineers go to anothe offshore rig to test GN ViST, and then go to one more offshore rig. Now more and more offshore projects.

The drying shaker unit is one of the main equipment in waste cuttings management system. It is used for further treatment of the drilling cuttings discharged out from primary solid control shale shaker. Comparing with the normal shale shaker, drying shaker has a large vibrating G force that makes the shaker recover more drilling fluids from cuttings. By using the drying shaker, the drilling fluids recovery efficiency would be highly increased and less waste discharged. To prevent the drilling fluids spraying out of the shaker deck and contaminating the area nearby, the drying shaker deck is designed to be cover with steel plate on top. 

To increase the drilling mud recovery efficiency, GN published the VIST vacuum shaker screen system that can be used especially in offshore project.

GN’smud cleaner is a 3 in 1 equipment including bottom drying shaker, desander cyclone and desilter cyclone. Features of GN mud cleaner

1. Bottom shaker is always same model with the primary shale shaker in same solids control system.

2. Hydro cyclone unit are 100% PU material for better wear-resistance performance. 

3. Cyclone manifold pipe frame is removable for easy transportation.

4. Installation of composite frame shaker screen for longer working time and large screen area.

Mud cleaner can remove the cuttings with size large than 20 microns in the drilling mud. Before feeding the mud into the decanter centrifuge, better to use a mud cleaner to treat the mud firstly as it can greatly reduce the solids content so that to reduce working load of the decanter.

GN Solids Control is open to communicate with clients in technics improvement and customized design. For more information, please feel free to contact with GN.

It is just another set of solids control equipment to Russia, but also not quite, collecting feedback, improving details, or do small customisations, that is what we always do.

After a whole day packing and marking labels, GN just shipped out one batch shale shakers and decanter centrifuges to equip the oil well drilling rigs in Russia. Shale shaker and decanter centrifuge are two of the key equipment in drilling mud recycling system. The shale shaker separates the cuttings by using the wire mesh screen opening size to block the coarse cuttings, while the decanter centrifuge is separate ultrafine solids by using centrifugal force.

GN shale shaker could be used in drilling mudsolids control system as the primary shaker unit and also as the high G force drying shaker in waste cuttings management system.
Below features make GN shale shaker the reliable performance in using
1. Shaker vibrating deck is completely heat treatment for higher vibration G force
2. Shaker is installed with GN self-produced composite frameshaker screen with longer working time.
3. Patented rubber sealing installation method make the replacement of rubber strip much easier and better sealing performance.

GN decanter centrifuge could be used in drilling mud solids control system for fine solids separation like the suspending barite recovery and useless cuttings removing. In the waste cuttings management system, the high speed decanter centrifuge could be used to treat the effluence discharged from the cuttings dryer. Besides the petroleum industry, the decanter centrifuge is also widely used in mining and environmental protection industry.

The decanter centrifuge shipped to Russia in this order is the popular 14 inch model with designed maximum speed up to 3900RPM. It could be control as fixed speed or variable frequency. 
Below features make GN decanter centrifuge excellent performance.
1. Bowl material is from duplex stainless steel 2305 with good machinability. 
2. Centrifugal casting technology makes the bowl material distribution evenly for a good dynamic balance. 
3. Tungsten material tile or bushing protection at abrasive part for longer working time and less maintenance. 
4. PLC control panel is available, and the sensors could be put on the centrifuge unit to monitor the status of the machine.

It has been a scar for lots of Chinese people, as it is bad reputation for made-in-china, and the pity part is there were actually lots of profiteer actually manufacturing bad quality products, so about 10years ago, when my client told me, they have never known a door handle is a draft iron ball, Im very embarassed, when an Chinese engineer from our client’s company emailed us to warn us to take care of the quality, we know we should make it right. So we did it, we focus on top quality products, and keep improving.

This year in Bauma, saw lots of hydraulic parts, gear supplier, which reminds me years ago, another client told me they can not find even one good hydraulic parts in China, I hope they do find one now. If not, I doubt they did not try hard enough, or did not pay reasonable enough.

There are many Chinese machine brands like Zoonline, Sany etc are doing pretty well, have their name internationally. You know when your clients, your friends tell you that they are proudly telling you they are using a Chinese brand, you know that is a comfort, that is a proud.

Also it is very good to find that more and more oversea companies are cooperating with local partners here to do local business, which means now it is not just admiringly use a good foreign brand, but also cooperating & competing.

For being quite a long time, the HDD mud recyling is just screening, or add some cyclones; though it is common sense for everyone sometimes that corroct sized combination of equipment can ideally targets drilled solid of different particle sizes from large drilled solids through to sand silt, clay and colloids; the decanter centrifuge cost money. While it get rid of 5~10 micron solids.

Decanter centrifuge have been approved for oil gas and lots of big HDD projects, that it works, save downhole tools life, and reduce the disposal costs. Then the topic comes to after the desilter cyclones, is it still worth to have a decanter centrifuge. Real conflict thing is until you use a decanter centrifuge, you can find out the real value in it.

Very recently GN have delivered a mud recycling system to Sinopec projects, with a decanter centrifuge. Decanter centrifuge GNLW363C-VFD is last stage separation equipment for fine solids separation. After several time recycling, there will be much fine solids in the drilling mud. The centrifuge is used to remove the fine solids to ensure the property of the drilling mud. Decanter centrifuge is fixed on a collecting tank with 4 supporting legs. Liquid is flow into the tank and solids will be collected by the screw conveyor and transferred out of the system.

If you would like to know more info about the decanter centrifuge for HDD projects, pls let us know.

HDD Mud system is also one of the main business from GN Solids Control, for quite a while, that is how we made ourselves different, we make compact HDD mud systems for different clients, flexible to customize, and with more and more experience, now we got several standard systems meet most of the requirements. Recently we sent out 3sets of HDD mud recycling systems.

Two Sets 500GPM Trenchless Mud Recycler for HDD Company in India, and 1 HDD Mud Recycling and Dewatering Unit for Sinopec. A standard self-contained trenchless mud recycler is consisting of mud recycling equipment, mud mixing equipment and mud collection tank. Different from the mud recycler in oil gas drilling industry, the trenchless drilling will discharge the dirty mud back to mud pit on the ground firstly, then use a vertical installed submersible slurry pump to transfer the mud to mud recycler system.

1. Shale shaker GNZS703F is the first stage separation equipment to remove the coarse solids. GNZS03F is the latest version shale shaker in GN production line. This model shale shaker is with 3 panel composite frame shaker screen that is fastened by using ratchet spanner, easily and fast.

2. GNZJ703F-1S8N mud cleaner is combination unit of desander and desilter. The mud cleaner under shaker is the same model GNZS703F. Normally, GN use same model shale shaker for easy future maintenance. 2 units centrifugal pump are equipped in the system for feeding the drilling mud to the hydrocyclone units for smaller sand and silt separation.

Most of the driller will use Three-stage separation procedure as shale shaker, de-sander, de-silter to remove the cuttings and waste solids step by step. This is a cost saving configuration. If higher separation request is needed, the driller will bring a decanter centrifuge into the trenchless mud recycler

Decanter centrifuge GNLW363C-VFD is last stage separation equipment for fine solids separation. After several time recycling, there will be much fine solids in the drilling mud. The centrifuge is used to remove the fine solids to ensure the property of the drilling mud. Decanter centrifugeis fixed on a collecting tank with 4 supporting legs.

Solids Control or Separation? What is now GN offering
Few days ago, got a call from client, we need the desanding unit, as shown in your separate flyer, with understanding now you are doing oil sludge separation, this is a different application. Got very confused actually after that call, well yes, we did quite some projects on oil sludge treatment, and it is getting better and better business, yet if you still stay with GN, you will understand.
GN Solids Control still a solid liquid separation company, we are doing separation job. In oil gas, we are offering packages of solids control, waste management, and oil sludge treatement; for civil projects, we are offering desanding units, self contained compact mud systems; in coring diamond drilling, we are supplying small mud systems; for mining, we are offering system, solid bowl decanter centrifuges; for food industry, we are offering various decanter centrifuge for option.

 

And in other application, we still offering separation solution, once we did helping a ship to prepare a separation system to help them get rid of all the staff from ship deck and ship body after a long trip.

And below is GN Product Lines

Expecting your call…

ViST have been a new product, with GN patent, and tested on site, comparing with similar products, now more orders on the way. This time the client purchased 6sets for an offshore project.

Due to the limited area, the mud recycling equipment on offshore platform is always with compact structure and high efficiency. The used drilling mud and waste cuttings coming from offshore platform normally will be barged to land for treatment. Thus, to maximally recover the drilling fluids will greatly reduce the time and fund cost in treating the waste cuttings. GN VIST vacuum shale shaker can greatly increase the volume of recovered drilling fluids.

Though so far GN ViST is only designed for GN shakers, and integrately with our own shaker in a very good way, we keep the flexiblity of putting this into all other shakers. The hopper design and connection of hopper to the vacuum unit is quite flexible.

GN ViST vacuum shale shaker is a shaker unit with a vacuum suction hopper installed under the last shaker screen. Shale shaker is the beginning of the mud recycling system, and drilling cuttings discharged from the shale shaker are always very wet with large content of drilling fluids. High recovery rate of the drilling fluids will greatly reduce the cost on cuttings treatment and new drilling fluids making. The ViST vacuum unit connects the shaker via a collecting pan under the last panel shaker screen at the cuttings discharge port. When the drilling fluids passes through the shaker screen, the vacuum unit will make a negative pressure to suck the liquid into the collecting pan, and then to the vacuum unit.

Benefit from ViST + GN Shaker

1. GN Screens compliant with API 13C, only supplier here in China certified by 3rd party

2. Hopper equiped onto shaker before it leave factory

3. Waranty & guarantee is for the whole unit. When if needed, shaker need to be modified to fit the hopper, someone may question the shaker waranty. If all from OEM manufacturer, no such problems.
