GN Solids Control can manufacture many kinds of shaker screen for replacement. They have control the core technology of the production. The screen model includes the replacement shaker screens for Derrick 500/2000 PMD/PWP screen, Swaco Mongoose PT screen and also NOV Brandt king cobra shaker screen. These models are mostly popular around the world.
Separating solids from liquids plays a key role in oil drilling mud recycling. Decanter centrifugal separator from GN Solids Control plays this crucial function exceptionally well. The working performance is strongly related with the working principle. So how it works?
In order to understand this, we need to define what is decanter centrifugal separator. Decanter centrifugal separator also can be named short as Decanter centrifuge or centrifuge. The most common model is vertical, horizontal and conveyor centrifuges. The principle behind a decanter centrifuge is based on the theory of gravitational separation. For example, if you fill a glass with a mixture of mud and water, over time the weight of the mud will cause it to settle down at the base of the glass. With the mud congealed at the bottom, the water will be forced upwards, creating a clear separation between the two. However, unlike the glass mixture, the process is expedited through the use of continuous rotation. In fact, rotation provides anywhere from 1000 to 4000 times the normal gravitational force, reducing the time required for separation from hours to seconds.
Decanter centrifuge has many kinds, classified as speed, it has high speed, middle speed, low speed; classified by drive type, it has belt drive, fully hydraulic drive and magnetic drive; classified by manufacturers, it has GN Solids Control. The former 3 brand are U.S. brand and the last one is China brand. The only China brand can compare with U.S. brand.
Hereunder, we listed some middle speed centrifuge which is popular used for weighted drilling mud barite recovery, overseas and domestic market.
Centrifuge uses high-G force to separate fine solids from liquid. It can be used to process weighted and unweighted, oil based and water based drilling mud. Popular centrifuge manufacturer like Derrick, Swaco and NOV brandt are US brand. Here introduce a China popular brand, GN Solids Control.
Let’s compare GN Solids with NOV Brandt centrifuge hereunder:
1. NOV Brandt centrifuge, HS-2171L centrifuge
The HS-2172L centrifuge is fed from the solids end of the conveyor. Mud is introduced into the feed chamber of the HS-2172L through a feed tube and, with the aid of a concave accelerator, exits through twelve (12) nozzles into the bowl.
The HS-2172L is equipped with variable frequency drive (VFD) control, which provides a controlled application of motor drive power to the centrifuge components (bowl, conveyor and feed pump). Customized hardware and software packages can be designed to meet specific installation and operational requirements. With a processing capacity of up to 550 gal/min (2082 lit/min), the HS-2172 series centrifuge is able to quickly process high volumes of mud while allowing prescribed mud weights and separation efficiency to be maintained. This enables the HS-2172 series centrifuge to produce fine cut points at higher flow rates, making it ideal for high-flow applications and critical-conditions solids control.
ADIPEC 2013, Abu Dhabi oil show is the largest oil show in Middle East area. It has a large influence in oil and gas field, especially for companies from Middle East and North Africa. This month, GN Solids Control Co., Ltd attend the show with there high speed centrifuge, GNLW363VFD. This centrifuge is the best seller in Middle East and North Africa.
1. GN customer around the world, using GNLW363VFD.
This centrifuge has a stable working performance and also good reputation from the customer. Now it has been used in Iran, Iraq, Kuwait, UAE, Egypt, Lybia, Nigeria, Tunisia, Argentina, Brazil, America, India etc, over 60 countries and areas.
Tunisia is a country located in North Africa. As an export-oriented country, the majority of the electricity used in Tunisia is produced locally. Oil production of Tunisia is about 97,600 barrels per day. That means this country has many drilling works under going.
GN Solids has already established links with many Tunisia national drilling company and Tunisia national mud Service Company. Only this year, they have exported many sets of solid control equipment and waste management equipment to Tunisia.
There are many pumps need to be used for solid control system, like centrifugal pump, submersible slurry pump, shear pump, screw pump etc. The pump is accessory equipment to solid control system, not main equipment, but also necessary for your smooth job. If the pump quality is not reliable, you may find many troubles during the work.
GN Solids Control Co., Ltd. is the first API and ISO certified solid control equipment manufacturer from China. Their equipment is widely used in many areas of the world. The reliable product quality and nice service win good reputation for them. Hereunder, we see one importance pump, shear pump in all perspective.
Hereunder, we want to introduce a kind of equipment connected solid control system and waste management system. It is screw conveyor, or name it auger. It is utilized to transfer solid waste or slurry from solids control system (including shale shaker, mud cleaner or centrifuge) to drilling waste systems for further treatment.
Classified by drive mode, Decanting Centrifuge has different models, like hydraulic drive, electric drive and also magnetic drive. Different drive model has different advantages and disadvantages. Hydraulic drive centrifuge can be started very smoothly, with less noise and less friction. But once some problems arise, it is very hard to maintenance. Electric drive is not that smooth when starting, but is easier for maintenance for trouble shooting, so that lead to less cost.
Some remarks:
FHD: Full Hydraulic Drive ; VFD: Variable Frequency Drive; Magna: Magnetic Drive
Derrick DE-7200VFD Decanter Centrifuge is Variable Frequency Drive Centrifuge which is designed to achieve larger treating capacity and keep pace with the ever-changing needs of the oil and gas industry. New model centrifuge has been combined with durability and reliability in a product that is easy to operate and fully adjustable.
But with time goes by, not only Derrick can fabricate this big treating capacity centrifuge, GN Solids from China have already control the core technology and can fabricate the big bowl big capacity centrifuge, GNLW553VFD.
Hereunder, we compare these two brand centrifuge, US brand VS China brand. And let us know more about the difference and similarity.
