vertical cuttings dryer

GN ViST vacuum shale shaker is a shaker unit with a vacuum suction hopper installed under the last shaker screen. The purpose to use the ViST vacuum unit under the shale shaker is for more recovery of the drilling fluids in the same conditions compared with shale shaker without ViST system, and the discharged drilling cuttings will be much drier, so the user can save cost to treat and disposal the drilling cuttings. Normally it is very difficult for the offshore drilling cuttings collection, treatment and disposal, sometimes client will ship them back to drilling waste management facility in land, the collection and shipment cost is very high, other clients use cuttings re-injection technology, some clients use Thermal desorption unit, some clients installed drilling waste management on the offshore rig floor, but normally the area for offshore drilling rig is very limit, it is hard to install a complete vertical cuttings dryer system. Because of these reasons, ViST vacuum shale shaker became very important for offshore.


As a professional solids control and drilling waste management system manufacturer in China, GN solids control, GN solids control keep developing new and advanced technology for oil & gas industry and provide the best solution for our clients.
Features of ViST Vacuum Shale Shaker


1. GN ViST vacuum shale shaker is suitable for oil based mud, water based mud and Synthetic oil based mud.
2. By using the ViST vacuum shale shaker, the drilling fluids recycling will be increased by 30%~50%, It greatly reduces the volume of drilling waste and the cost to transport the drilling waste.


3. By using this ViST vacuum shale shaker, no need extra high G drying shaker again; The compact design did not take much area at site.
If you are interested in GN ViST vacuum shale shaker, pls contact with GN solids control.

This week we shipped one unit of oil based drilling waste management system for CNPC, they ever bought similar system before for their domestic and international projects.


To get ideal result of the discharge cuttings and recover oil as much as possible, the performance of vertical cuttings dryer is the major concern. GN has a lot of successful experience for drilling waste management projects, our vertical cuttings dryer has been improved to E version from the year of 2013 when we firstly produce the vertical cutting dryer as per our client’s suggestion and site feedback. From the first A version to the existing E version vertical cuttings dryer, it has been more and more user friendly and maintenance cost has been reduced a lot.


We have 900rpm, 1200rpm rotary speed for option to meet different requirement, the G force is up to 420G / 750G, and the screen basket opening can be 0.25mm, 0.35mm, 0.5mm for option for different drilling waste conditions. The screen basket and screen basket frame is separated, the operator only need to replace the single screen basket when it is wear. The independent oil lubrication system is for better lubrication of the bearing to prevent it from over heating. The automatic interlock system between oil pump motor, main motor and flush pump motor is equipped in case that the main motor starts before oil pump motor.
The decanter centrifuge is used after the vertical cuttings dryer to treat the fluids discharged from the vertical cuttings dryer, after treated by the centrifuge, the fine solids over 2 microns can be separated mostly, the fluids can be used to prepare for new drilling fluids or reuse directly. The high speed decanter centrifuge is used for low gravity solids, the max speed is up to 3900rpm.
If you need oil based cuttings treatment system, pls contact with GN freely.

GN solids control shipped several units of drilling waste cuttings screw conveyor to Africa Client, this is repeat orders for the same clients for many years. The screw conveyor is widely used for transferring and collecting the drilling waste cuttings from solids control system.


The installation of screw conveyor:
The screw conveyor might be installed on different place for different functions, for example, it can be installed along with the solids control system mud tank besides the shale shaker, mud cleaner, decanter centrifuge to collect the discharged drilling cuttings; it can be installed slantly under the horizontal installed screw conveyor to transfer the drilling cuttings to vertical cuttings dryer; it could be installed under the vertical cuttings dryer solids discharge port to transfer the discharged solids cake outside automatically, it can be installed under the decanter centrifuge solids discharge port to transfer out the solids automatically. It can be used in cuttings solidification unit to transfer the 3 materials and mix them together.


The screw conveyor can transfer the material with less fluids content in the cuttings, otherwise it will flow back and spill out. When the fluids content is very high, we need to use vacuum pump, slurry pump or hose pump to transfer to the drilling waste management system.

ADIPEC 2017 will be held in Abu Dhabi next week, this year as the oil price is recovering gradually and today the WTI price has reached up to USD 57 per barrel, we believe ADIPEC 2017 will be more successful than last year’s and will attract more and more attendees and exhibitors to attend the show, exchanging the ideas and share the latest technology in the oil and gas industry.


GN Solid Control is the advanced manufacturer for the solid control and waste management equipment and system. GN has been consistently attending the ADIPEC show for many years, and each year the customers will see GN’s growth and development. Now GN has become the one stop shop for all the solid control equipment, from shale shaker, decanter centrifuge, cutting dryer, to the various kind of pumps, such as centrifugal pump, screw pump, to the agitator, mud gas separator. GN not only make some new in equipment, but also make the great upgrade on the shale shaker screen. From the beginning of this year, GN has fully upgraded its shaker screen from the old steel frame screen, this will make much better performance and longevity that ever before. Also the new composite frame screen has larger non blank area and the processing capacity has been improved dramatically. And most of the screens are 3 layers, the wire mesh suppliers are the same as the other famous brand screens, such as the MI SWACO, DERRICK. If you are interested in this product, you could come to GN’s booth and take a look at it. We believe you will be impressed by the screen when you finally see it. Seeing is believing, welcome to GN’s booth.


ADIPEC 2017 is just around the corner, all GN staff is ready to welcome the friends from all over the world. Also welcome you to log on to our website www.gnsolidsamerica.com , and if you want to get more detailed info, you can send your inquiries to lucas@gnsolidscontrol.com.

Recently GN just sold two decanter centrifuges to a US customer for their project in Canada. The two decanter centrifuges are 22 inches and 14 inches. This is a new project for the soil remediation, which is a new area for the decanter centrifuge application.
As an advanced decanter centrifuge manufacturer, GN’s decanter centrifuges have been sold to more than 60 countries, and after being tested and applied in the job sites, GN’s product performance proved to be reliable and consistent. Now GN can manufacture not only the single solid control equipment, but also the whole cleaning system, such as the shale shaker, decanter centrifuge, mud cleaner, cutting dryer, and various kinds of pumps. All the equipment can work together and combined as an integral part to clean the contaminated soil and water, and make it reusable and environmental friendly. The 22 inch bowl size decanter centrifuge has medium speed to do the coarse separation, the 14 inch bowl size decanter has fast speed to do the finer separation. You can also add a flocculate system to separate even finer solids, the size almost close to zero.


Now all the decanter centrifuges have been upgraded, the bowl material is 2205 stainless steel which is very tough and needs little maintenance. The solid and liquid discharge port material is tungsten carbide, which is tough. The screw conveyor surface is covered by the tungsten carbide tiles, which is replaceable when it is damaged. The bearing is adopted the world famous brand SKF and all the electrical control is also using the world famous ABB or SIMENS, according to customer’s needs and requirement. Now the Canadian customer is very satisfied with the decanter centrifuges and they are using it to do the soil remediation work and water cleaning.
