A .The adjustment of the drum speed.

 

The adjustment of the bowl speed is performed in  manual adjustment or decanter centrifuge plate prescribed maximum working speed following the adjustment.

Different rated speed by installed different size wheel by diameter for driving the main belt wheel to set different drum operation speed

In variable frequency drive decanter centrifuge will paired with control panel that allow increase and decrease the drum speed.

By fine-tuning the speed of the drum, it can perform more precise solids particles separation.  It can also improve the wear of the drum, the vibration and the noise to extend the service life of the decanter centrifuge.

The separation purpose or drilling fluid solids content  is by the choice drum speed. For instance, barite recovery or processing high-density mud, it is suggested that the low spending  speed. For general medium density mud prefer choose medium or high speed.  The low density mud is ideal for using high speed decanting centrifuge.

B. The adjustment of the differential drive

 

Centrifuge differential speed (back drive is also refer by) in its within the prescribed scope of, do not suggest user to adjust and it can only adjust in a small range change the parameters.

Different speed centrifuge adjustment methods are remove the original auxiliary motor pulley, and reloading large diameter or smaller diameter belt wheel  Auxiliary motor pulley  change the differential input shaft speed enhancement in result of differential speed decreased. On the other hand, it can also cause differential speed increase.

 

Operators must understand that regular maintenance on the centrifuge such as regular cleaning the inlet and outlet by filling water or diesel depends what kind of fluid it needs process.  It is also crucial that  add grease to the bearing parts to ensure proper lubrication.

“GE, an industrial company, but also a digital company”. Some people may have watched this commercial on American’s main media, like CNN or NBC and we may wonder what does that mean? The answer is it represents the future trend-digital and automation.

As we all know, GE is the conglomerate in many industries, such as energy, electric appliances, aerospace and so on. So its action and strategy will represent the future of the industry. Recently GE just opened its new main office nearly San Jose and recruited a lot of engineers from Google, Apple, Microsoft with background of electrical engineer to develop its own system  called “Predix”, which is the world’s first and only cloud-based operating system for industry. GE plans to make “Preix” as the industry standard similar to the position of Microsoft Windows system in the PC industry. It will realize the digitalization and automation of the industry, including the oil and gas industry. One example for this trend is on June 14,2016, GE and Technip signed memorandum of understanding to explore digital solutions for new LNG projects. LNG will have great potential for growth as the world’s demand rises. So this prosperous area will be co-developed by the combination of strength of GE and Technip. GE will provide it reliable equipment solutions for the global LNG facilities, through sensors, advanced analytics and diagnostic expertise. Technip will provide unique expertise in EPC for LNG projects.

Comparing with other solids control equipment like the shale shaker, desander, desilter and other equipment, the decanter centrifuge clearly need more attention and more care during operation in order to make sure a good performance, especially on the 24*7 running jobsites.
As the leading manufacturer of solids control and waste management manufacturer in China, GN has been producing hundreds of decanter centrifuges and GN centrifuges are working all over the world, GN has following tips to share with the decanter centrifuge owners or operators.

a good choice of centrifuge

GN decanter centrifuge

1. Before confirming the model, collect as much as information including the those points: the jobsite condition, like the temperature, the end users’ special request like the EX standard (ExdIIBT4? IEC EX? ATEX or Gost?), the allowable max electric current, and electric specification of the jobsite(380V, 50HZ? 460V, 60HZ? 415V, 50HZ or others?). And try to collect as much information of the material to be treated, the largest particle size, the solids contents before treatment, and the allowable largest particle size and solids content after treatment. A right choice of decanter centrifuge is the precondition of its good performance. Those are GN Centrifuge Models for your reference.
2. Before installing and commissioning of the decanter centrifuge, read the user’s manual carefully and get a general idea of the specific model of decanter centrifuge and the control panel. Normally, the VFD controlled decanter centrifuge is more complicated to operate, the operator need to have both mechanical and electric knowledge to handle it, at least for operate it.
3. Assign a specific professional engineer or operator for each decanter centrifuge. His work is to observe the condition of the decanter centrifuge and discover any problem at the first time and solve it. Because the centrifuge is high speed running machine, and when the mud condition changed a bit, it affect the performance and the centrifuge service life.
4. Lubricate the centrifuge on time, especially the bearings. Like GNLW363CG decanter centrifuge, the bearings are original SKF bearing. Good bearings ensure a longer service life on basic that you maintenance them carefully. Per manual’s instruction, some points of decanter centrifuge need to be lubricated every shaft and some need to be lubricated after running some hours.
5. A standard equipment is designed for common conditions, but not for all. In some cases, the end user need to make the jobsite condition to suit the equipment, like to make some isolation for keeping the equipment warm or cool, sometimes, the end users even put the decanter centrifuge in a air conditioned room or container to get an ideal performance.

New environmental regulations are more focusing on the final disposal of drilling waste cutting. Normally there are several methods for final treatment of the drilling waste management . Cuttings Re-injection is also one of the main methods. In many developed countries like USA, Canada and Germany, cuttings re-injection technology is already very mature. China drillers are now more and more adopting this technology for final treatment on drilling cuttings.

Cuttings Re-injection system is always including 3 parts as cuttings transferring, cuttings screening and Cuttings Re-injection. In the first stage for cuttings transferring, there are shale shakers, centrifuge and other traditional solids control equipment doing the same job for drilling fluids recycling. The cuttings discharged from the shale shaker will be collected by the screw conveyor and then transferred to a Venturi device to fast transferring to the storage tank. Here the centrifugal pump will be equipped for shearing the cuttings. In mud mixing system, a fine mesh screen shaker will be here for screening the cuttings suitable for re-injection to underground. The injection pump is triplex cylinder type with pressure around 40MPa. With cuttings fed by the centrifugal pump, the injection pump would pump the cuttings back to the underground via the well.

The well for re-injection could be either a new drilled one or an old well. Always a new one would be better to avoid the cuttings leak into the oil production layer. The re-injection layer could be under or above the production layer. This technology requests accurately analysis on the geological condition as not everywhere could be chosen as a point for cuttings re-injection.

Driller need choose the cuttings disposal method according to specific condition. Cuttings re-injection is a very good method for offshore drilling cuttings disposal, as it will save much time on shipping the cuttings back to onshore plant for treatment. Especially the application of SBM makes the base liquid is biodegradable for better environmental protection.

Two weeks ago, GN sales team members and GN top management were back from Houston, USA. They went to Houston for the yearly oil and gas festival, the OTC Oil Show. This OTC was a success for GN. Most of GN’s equipments in stock in Houston warehouse were sold out and GN Solids Control’s name was better spread among the oil drilling and oil service companies.

After the OTC Oil Show, GN staff in USA branch has to be busy for a while for packaging the equipments and deliver them to the buyers.

GN Solids Control in OTC

GN GOT BIG SUCCESS IN OTC

This OTC, GN has two stands, one is in Chinese companies’ area. Even before GN set up the branch with name of GN Solids America in USA, GN’s brand was known to many companies in the world. Now this brand becomes more and more famous.

Of course, this is not only because of the Oil Show, the more important reason is that GN’s products are of high quality and good performance. What are GN’s core products and which are the best sellers?

  1. GNLW363CG Decanter Centrifuge. Decanter centrifuge is not only used in solids control, but also, more widely used in waste management systems. unless other solids control equipments, centrifuge shows more about a company’s producing ability. It could be used for solids control, drilling cuttings waste management equipment after the VG dryer or the high-G shaker, and also plays as dewatering centrifuge for drilling fluids.
  2. GNCD series vertical cuttings dryers. Comparing with decanter centrifuge, it is a new product. It is designed originally for the oil based mud drilling cuttings waste management. But as some GN clients are using it in water based mud also, GN now designed the 5th generation with new material in order to deal with the water based mud. Now more than 50 sets of GN vertical cuttings dryers are working in many countries in the world and the feedbacks are better than OK.
  3. GN shale shakers and high G shakers. The shakers, solids control shakers and high G shakers for waste management systems are both important, they are used to separate out most of drilling cuttings.

4. GN shaker screens. GN make high quality of shaker screens for both GN’s own shaker and other brands’        replacement shaker screens.

In the past CIPPE 2016, GN Solids Control brought its centrifuge family to the show, all the centrifuges from the 9 inch baby centrifuge to the 22 inch big brother centrifuge, standing in a row and visited by many visitors and end users.

Especially the GNLW363 Decanter centrifuge, both the old look one and the new design were shown in CIPPE 2016, and the new one was positioned on a skid. What’s the differences between each generations GNLW363’s?

1, first generation GNLW363, the original design for 14 inch decanter centrifuge, with the two motors on each side of the centrifuge. although the material used is better than others, the centrifuge is still an old looking one.

2, second generation GNLW363B, it is more international looking, as GN Solids Control has been selling its products to many countries and regions in the world, and GN’s products design became more and more international, GNLW363B decanter centrifuge’s motors are located on same side of the centrifuge, it allowed the operators to have more space for operation.

  1. third generation GNLW363C decanter centrifuge, for outlook, it is similar to GNLW363B, with two motors on one side. But there are more small but useful changes on GNLW363C, because the centrifuge was used for many applications since then, like the oily sludge separation, the dewatering unit and etc, with feedback from jobsites, GN re-designed it and better it a lot.

4, forth generation GNLW363D, the inside design is similar with GNLW363C, but the outlook is quite different, as the structure is more compact and total weight is less, easy for air shipment in case of urgent use.

For the same model of GNLW363D/C decanter centrifuges, GN has optional control panels like fixed speed control panel, VFD control panel of normal one, and the positive pressurized control panel with PLC smart touching screen.
