For some difficult TBM project, we may get somewhere we do not like, too much solids, too high mud density, then the dewatering unit is not working so efficienly. Though filter press is a good option, here we can have some improvent. To make the dewatering unit working as we wanted.
TBM mud system
 If you add a smaller decanter centrifuge (Let's say 40m3/h)  to treat the drilling mud without polymer before feeding to the exisiting centrifuge with poleyer, it can reduce the  mud  density from 1.7 SG  to around 1.2 SG 
  Then you treat the 1.2 SG mud with your exisiting centrifuge to get clean water which is around 1.0 SG. From our engineers experience, you can get the centrifuge capacity from 8 m3/h to around 20 m3/h for getting clean water in this case, maybe more by increasing the speed and differential speed. And you can save a lot on the volume of the polymer.
  Normally, for geting clean water, our client will treat the mud by mechanical method first to get the desity down, that means to get most of the solids out from the mud, for the ultra fine solids, they use polymer to do dewatering.
 Since the mud is still heavy with 1.7 SG  after the desander treatment. So we suggest to put a centrifuge to reduce the density of the mud to around 1.2 SG before feeding to the decanter centrifuge with polymer.
  That means, first phase is mechnical only, second phase is chemically enhanced centrifuge treatment. This way will increase the total capacity of the system to at least double capcity of existing unit.
  And also you can save the polymer and chemicals.  
  Moreover, the mechanical treatment centrifuge, you only need to use a small centrifuge with cheap price, not the big bowl, to match the chemical enhanced phase separation.
  Another way is to increase the mixing time of the chemical with the mud by extend the outside feeding tube of the centrifuge before feeding to the centrifuge.
   And also increase the bowl speed to around 1800- 2000RPM and increase the differential speed to around 30 RPM, anyway, it should be within the limit of the centrifuge not to get the centrifuge overload.

GN Solids management finished the assembly for three Sets one thousand power unit oil rig solids system for a drilling company in Europe, the shopper purchased one set of 750 power unit oil rig solids system from GN. This three sets mud system is that the repeat order for this shopper.

Three sedimentary rock Shaker Tank with VI sedimentary rock Shakers, three Mud Cleaner, three vacuum degasser.

One Centrifuge Tank with one middle speed carafe centrifuge and one high speed carafe centrifuge.

One active mud tank with agitators and dust guns.

One suction mud tank with mud agitators and dust guns.

One intermixture Tank with intermixture hoppers and intermixture pump.

Solids management instrumentation

So totally, actually, the solids management systems embrace one complete set one thousand power unit oil rig mud system and 2 additional shaker tank with three part solids management instrumentation.

As these solids management systems are exported to Europe market, all motors and electrical management panels are needed to be ATEX certified and every one machines have to be compelled to be metallic element certified. GN Solids management is one in every of the few firms in China UN agency hold those certificates.

Since GN Solids management specialize in the prime quality product, currently GN Solids management market share are growing quick in Europe and America market.GN Solids America conjointly provide the solids management rental services in North America market.

My collegue just shared another great news, after sent 10 sets of decanter centrifuge to Africa, plus another big order with more than 40 sets decanter centrifuges, now in Africa we have far more than 100 decanter centrifuges. 
You must wanna know what is happening. Top quality product, best service, and public praise.
Except more than 30 years experance engineer teem, we also hired another team lead by engineer who deal with Alfa Laval decanter centrifuge for moren than 20 years, went to many sites, different applications. We get more updated features from GNLW363B, to GNLW363C, after collecting all the feedbacks from different sites. A more robust products finally come to the world, while we still keep improving at the same time.

GN Decanter Centrifuge
Normally when a client trying to find a proper decanter centrifuge, they may consider:
1. Material
2. Screw protection
3. Failure protection
Freely to let us know if you are interested in details of GN Decanter Centrifuge.

The fixed speed centrifuge & variable speed centrifuge is good combination for barite recovery and mud weight cutting. Fixed speed centrifuge is mainly working for mud weight cutting; the variable speed centrifuge is mainly working for barite recovery, most working under 2200rpm to 2700rpm. When the job only need one function like mud weight cutting, the two centrifuge can working together at similar speed. During the actual job process, the user need to continuously test the feeding mud, discharge mud and continuously adjust the bowl speed of centrifuge to get proper treating results.
In the recent orders, client normally purchase different centrifgues with fixed speed and VFD. For more flexible applicating on site.

gn solids control E1360

CIPPE is already the biggest Oil Gas Exhibition in the world, according the number of visitors, uhh, it is in China. Though it seems like joking, more and more people from all over the world are noticing this exhibition, and found, or trying to find a good quality supplier here; for their drilling operations. Especially when the oil price keep going down, everyone need find some good products, balancing quality and price.
No wander GN Solids Control keep developing very fast, as a company keep and only focus on top quality solids control & drilling waste managment. We keep improving our products, collecting feedback, learning from our customer, learning from other competitors. and use it in our products.
