Every year, GN Solids Control provides more than 100 sets package treating systems. Here are the main treating equipment in this pitless drilling waste management system. 1.GN Hi-G Drying ShakerGN Hi-G Drying Shaker has a larger G force up to 8.0 G. With the excellent quality vibrator to drive the shaker deck fixed with GN made shale shakers to separate solids from drilling mud. Shaker deck is made of SS to protect from rusty.  A hopper type feeding box is mounted on the back of the shaker, drilling waste can be feed easily by a screw conveyor. Flushing nozzles are located on the top of the shaker to eliminated those blocked holes by high pressure drilling mud, and a anti-spraying cover is fixed on the top. 

2.GN Vertical Cuttings DryerGN Vertical Cuttings Dryer is mainly used to treat OBM and SBM. Usually after treated by GN vertical cuttings dryer, oil on the final cuttings is less than 5%. Flights are hard faced to HRC65 for long time usage without weariness. To keep the screen basket from blocking, an air knife system is also used to provide high pressure air to blow off those stuck stones. 3.GN Vacuum PumpGN Vacuum Pump is one transfer pump especially designed to move high solids content, large viscosity materials. An air compressor is used to provide driven force.GN Vacuum Pump here are used to transfer those drilling wastes discharged from shale shaker and cuttings dryer. Solids less than 75 mm can be transfer under automatic running status and manual mode.

Dual Motion Shale Shaker Off to Go

GN dual motion shaker includes two working mode: one is linear motion and the other is elliptical motion, each mode can be adjusted by using the switch on the control box. Recently sent few sets to an International company. GN dual motion shale shaker can be used in different drilling depths and fully treat the drilling mud. Usually, GN linear shale shake is mainly used in the first and second drilling, while the elliptical motion is suitable for the further depth drilling such as  third time drilling or even in the forth drilling. GN Solids Control manufactures 300 sets to 500 sets shale shakers every year, customers from more than 70 countries are using GN shale shakers especially those customers from oil and gas drilling industry. Actually most of the shale shakers are Linear motion. Then what is the advantage of the linear motion shaker? As you know, it is simple. Well and Hi-G force, better screen panel penetration, larger treat flow rate, direct contact with drilling cuttings, bigger throw and vibrate angle, and longer stay time on screen panel etc. Especially suitable for mud with low viscosity, large capacity, high solids content, big and solid drill particles etc.   Freely to contact us for more info.

Slurry Dewatering Decanter Centrifuge for TBM project to Singapore

GN Solids Control last week shipped another set of Slurry Dewatering Decanter Centrifuge to a Singapore customer, who will use this system in TBM slurry separation. As a turnkey solids and liquid separation equipment provider, GN Solids Control can provide customizes slurry treating system based on customer’s demands. 

Most of GN Solids Control Slurry Treating Systems are provided in oil & gas industry, while GN TBM Slurry Separation Plant is also very popular in TBM, Pipe Jacking or Trenchless construction etc, as a large quantity of mud is occurred after multiple times circulation. It’s very necessary to use GN Slurry Dewatering Unit as those finer solids usually cause increased mud weight and bring larger chance to wear drilling machine.GN Solids Control has provided hundreds of Slurry Dewatering decanter centrifuges in the world, includes USA, Canada, Kuwait, Singapore, Japan, England etc.

Here are the main treating equipment in this GN TBM Slurry Treating System:

1.1000G Mud Recycling System

GN Solids 1000G has the flow rate of 1000 GPM. It is designed in a compact structure includes desander cyclones and double deck shaker. TBM slurry is feed into 10 inch cyclones by using a submersible pump or centrifugal pump, after treated liquid fall into the bottom middle tank. 

2.Decanter Centrifuge

A screw pump sucks the mud from 1000GPM mud recycling system and feed into GN decanter centrifuge. Finer solids around 2-5 microns can be separated out by high speed decanter centrifuge, here one 22 inch bowl centrifuge GNLW553 is used. 

3.Flocculent Dosing Unit

In order to eliminate most of those larger particles, GN flocculent dosing unit is also provided. Flocculent is feed by dosing pump into decanter centrifuge. 

4.Standard Container

Above mentioned GN equipment are all fixed inside standard containers, which are easy to move among different work sites.     

GN Solids Control provides different flow rate systems, all are in a compact structure as they are mainly used in urban area with limited working room.

Shale Shaker & Mud Cleaner to Domestic Market

Have to admit, China have done a very good job on this COVID 19 crisis, now this is one of the safest place. And though lots of people used to work at home, sealing off for around 2 month, it is almost over. Now most of the production recovered. Except keep exporting to the existing client for them to keep moving, now more and more local drilling companies start working, buying equipment and spare parts, life moves on. Recently we delivered some shale shakers and mud cleaners to a local drilling company. 1.GN Drilling Mud Desander GN drilling mud desander is largely used when eliminate solids larger than 55 microns. Drilling mud desander is shale shake fixed with multiple sets 10 inch cyclones. A centrifugal pump is usually used to feed the slurry into GN mud desander. Cyclone is using centrifugal force to separate mud under a high rotating speed after the centrifugal pump feed the mud at a high tangential speed. Due to the mud is combined with different densities solids and liquid, solids are moving upwards along with the cyclone as the centrifugal force is larger while the liquid is separated with the solids and rotated to fall off to the cyclone nipple. Eventually, solids are separated out from the the top end of the cyclones. And liquid fall on to the shaker screen panel and to be further treated. 2.GN Drilling Mud Desilter GN desilter is pretty similar with GN desander. The only difference is GN desilter fixed with 4 inch cyclone groups. It is normally seen that the cyclones are all in even number. GN desilter helps to remove solids larger than 25 microns. When using different API nos. Shaker screens, the bottom shaker can have different cut point.   Despite the crisis, we sincerely hope all our clients, and whoever happen to notice this article, all it well and stay safe & good health.
