Well as you may noticed this is the first unit tank cleaning skid system, after tested with some analog scenarios material test, with proper chemical testing, we have seen some very good result. The video also have been posted online. FYI.
https://youtu.be/Q96AZlOG4oY

GN have been doing research on the tank cleaning skid for a long time, from start, the only option would be shaker + decanter centrifuge, as that is the only thing we are familiar with, and then after we know more about other equipment with different principle. Also learn more and more from clients, partners, suppliers on chemicals, we have now more equipment there, to be more flexible, and able to let client add chemicales to help or improve the separation efficiency. 

The basic working progress is:

High Pressure Centrifugal pump (8) pump clean water from Buffer tank (7) and supply to tank cleaning machine(2) to clean the mud tank.Suction Pump(2) suck dirty wash water from mud tank through the strainer (1) which will filter the coarse solids.The suction pump (2) will feed dirty water through the static mixer to inclined plate clarifier (5).The chemical dosing system (3) will supply chemical/  flocculants to the static mixer(4) to mix with the dirty water to enhance the separation in the IPC.The inclined plate clarifier (5) will separate the settable solids.The clean water from IPC (5) will overflow to buffer tank (7) The buffer tank level control system will control the pumps automatically.Membrane Pump (6) will take the settable slurry from the IPC (5) to Skip

We have two more system on production, will be ready soon, if you are interested in this, and wanna check by yourself, freely schedule with our sales team.

This is the first time GN Separation went to the show, GN attended the IE Expo China in Shanghai, and got lots of attention, also many potential clients. In the show, GN brought the main products like Vacuum Pump, Decanter Centrifuge, which is the main product for GN Separation, for transferring, conveying. The subjest is mainly regarading Water, Waste, Air and Soil, and it is part of IFAT. In 2020, GN will also present in IFAT Germany. 


GN Vacuum pump is purely phneumatic driven pump that could be used to transfer liquid, sludge, powder and even dry solids. It is widely used in sewage sludge, wastewater and kitchen waste transferring.


Decanter Centrifuges
is the other two main actor in the booth, GN now has already developed several series of decanter centrifuge, for different applications. 
GN also showed the decanter centrifuge at the show. Comparing with the filter press machine, the decanter centrifuge is capable of working continuously and with small footprint. GN is with more than 10 years’ experience in manufacturing the decanter centrifuge. In choosing the material of the centrifuge bowl and screw propeller, GN fully considers the fabrication availability and pneumatic balance. By doing that, the decanter is with a longer working life and less maintenance requirement.


Why GN Separation? GN Separation is a sub-brand of GN Solids Control, though literally it it reversed, GN Separation is more focusing on Environmental Protection, Food Industry, etc., while Solids Control as the name shows, it is about oil and gas. Since various decanter centrifuges have been developed, now GN with different brand is capable of doing lot of different projects, solve more separation job.

After OST15, and several OST1 system delivered, now another standard oill sludge treatment system sent out to an Asian client. After some site experience, the OST5 system also has been upgraded, in details, to have better result, and more user friendly. The basic design is same as other systems, to do 3 phase separation. 

The first step would be blending, to have one or two tanks, mixing the oily sludge with water / diesel, and heating the fluids up, to make it more flow-able, then been pumped thru the shale shaker, after separated by the shale shaker, where bigger size particle size are separated, and fluids are picked up by centrifuge feeding pump, then the decanter centrifuge separate the small particles out, the discharged fluid, which contains oil water and small portion of solids. This part can flow into the disc stac or transfered by a centrifual pump, to the disc stac separator.

After the disc stac separator, you get the 3 separted result, solids / sludge, oil, and water. Well you might be wondering, what kind of result we are talking about here, normally for solids, the remaining oil content is 1~3%, not enough to discharge directly, based on most of the laws all around the world, which means the main purpose of this system is actually REDUCE, not the final. As for oil, BSW will be less than 3%, for water the remaining oil would be about 1000ppm. I believe DAF or filter will be needed in the following steps. 

For this specific project, the client knows us long time ago, and have been discussing with us for the details, unitil we showed them more videos, and after they checked a few sites, they finally come to an order. We also warmly welcom all of you who is reading this post to visit our factory, our booths, our sites uh where need to be approved before we go, all others you can freely to visit anytime.

Drill Waste Management system, more often referred as DWM, is a very important unit in drilling projects, it normally contains Vertical Cuttings Dryer or called Verti-G, and a decanter centrifuge, each equipment comes with a screw pump, the one for cuttings dryer is for flushing, the one for decanter centrifuge is feeding, then the screw conveyor, to feed the cuttings to vertical cuttings dryer. The systems or equipment to Russia is normally come with containers, and the main reason is weather proof, in the horrible weather place, you got some protection. It also bring some extra bonus, i.e. easier for transportation, it is a whole unit, so easier for on site installation, less rig up / rig down time. If you are worrying about the maintainces, then we did worry when we design it, except the overhaul time will be a bit complicate which you will need bring everything out of a container, and put it back; all the other maintaince is ok. So as soon as the equipment is robust, that is not a concern.

More and more offshore projects now choose GN products, before no one likes Chinese products for offshore is because of reputation, not enough confidence, and whenever count on the hassles, pay more and get EU / US products, plus, do you have the certifications.

Though it might not big steps so far, but we are on the right direction

offshore shale shake

The drying shakerunit 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.

To make sure the shale shaker comply with offshore application, GN also invite, CSC come to our yard, assist on the certificates on lifting parts.

As we get more and more experience on offshore projects, soon enough we will be able to offer even more products, with more competitive price.
