Vacuum Degasser

This week GN solids control shipped one batch of solids control equipments to Russia, the client inspect the equipments in our factory in Beijing before dispatch to Russia. We welcome all the clients to visit our factory before order and after order before delivery.


The solids control equipments they ordered including linear motion shale shaker, mud cleaner, decanter centrifuge, centrifugal degasser, this is their repeat orders since 2017, they keep repeating orders every month during the past years, and make mud tanks system locally. Sometimes they replace the old equipments from their existing rig solids control system.


The shale shaker, mud cleaner, vacuum degasser/ centrifugal degasser, decanter centrifuge are our main products and the most popular products, we have many options for decanter centrifuges with different size from 9 inch to 30inch for different applications, for each bowl size, we have 2 models with different ratio. For 9 inch bowl size centrifuge, we have GNLW224D and GNLW224E-VFD, for 14 inch bowl centrifuge, we have GNLW363C, GNLW363-VFD, GNLW364C-VFD, for 18 inch bowl centrifuge, we have GNLW452, GNLW453C-VFD and GNLW454D-VFD , for 22 inch bowl centrifuge, we have GNLW553C-VFD, GNLW554D-VFD for option, for 30 inch bowl centrifuge, this is the max centrifuge we produced at present, we have GNLW764D-VFD centrifuge, this is mainly for tunneling project which need a huge volume of mud.


The linear motion shale shaker, we have 2 panels, 3 panels, 4 panels and double deck shale shaker for option, all the shaker screens are produced by our own workshop with our brand GN solids control, the composite material shaker screens produced by GN has been approval by many clients in the world for their oil & gas drilling rig.

10 units of shale shakers are shipped to India drilling company this week, they also produced one set of solids control shale shaker tank ready for shipment, including 3 units of same model shale shaker, 1 unit of mud cleaner, 1 unit of vacuum degasser, 1 unit of mud gas separator, 2 units of centrifugal pumps, and necessary mud agitators, mud gun, and 1 unit of mud tank.


GNZS703F-HB shale shaker is one of the best sold model shale shaker, with 3 panel composite material frame shaker screens, we produce OEM shaker screens in GN own shaker screens workshop. Except for the OEM shaker screens, we also produce durable composite material shaker screens for world famous brand shale shaker, like Derrick FLC 500 series, FLC 2000 series, hyperpool, D600, etc, Brandt King Cobra / Venom, VSM300, MI-SWACO Mongoose PT,MD 2/3, FSI, etc. Compared with the steel frame shaker screens, GN made composite material shaker screens with 20% larger effective screen area, the working life is much longer, the storage period is up to 5 years.


The mud cleaner is the combination of desander cone, desilter cone, underflow shale shaker, the treating capacity is different by using different quantity desander cone and desilter cone. GNZJ703F-1S8N with 500gpm capacity with 1ea desander cone and 8ea desilter cone. GNZJ703F-2S12N with 1000gpm treating capacity with 2ea desander cone and 12ea desilter cone. GNZJ703F-3S16N with 1500 gpm treating capacity. The feeding pump for mud cleaner is GN made centrifugal pump , the parts and installation dimension is 100% interchangeable with world famous brand pump.

1500 HP drilling rig solids control system is ready for shipment to India, this is not a complete solids control system, but the essential mud tank for the solids control system- shaker tank, the technical specification is as below:


1) 3 units of GNZS703F-SHBF shale shaker with 3pcs screens with composite material frame shaker screens
2) 1 unit of GNZJ703F-S2S12NF mud cleaner which is desander cone, desilter cone and under flow shale shaker which is the same model with shale shaker


3) 1 unit of horizontal vacuum degasser GNZCQ360A
4) 1 set of mud tank equipped the equipments mentioned above, the mud tank dimension is 14000 x2800x 2500mm, including the trip tank, sand trap, desander compartment, desilter compartment, degasser compartment
5) 2 units of centrifugal pump as feeding pump of desander and desilter
6) 1 unit of centrifugal pump as trip pump
7) 1 unit of mud gas separator GNZYQ1000A
8) 1 set of carbon steel material shed for sun proof, rain proof


The one mud tank design is to meet the client’s requirement to replace the old shaker tank, and the remained part of the existing solids control system is still in usage. All the necessary connection dimensions can fit with each other through good communication with clients. The explosion proof electric control system is equipped to control all the electric motors in the system and the big motors are controlled in the MCC at client’s rig site.
Features of the solids control system:

Recently GN just got a new order of mud recycling system for 1000HP drilling rig from a customer in Romania. This is a full set of mud recycling system and now the production for the system is almost done, will ship to Europe very soon.


This system consists of the main components: 5 40 feet container sized mud tank, 3 shale shakers, 1 mud cleaner, 1 vacuum degasser, 2 centrifugal pumps, 2 mixing pumps, 20 agitators. The mud recycling system meets the Europe CE standard and ATEX explosion proof standard. Mud recycling system is very important during the drilling process, it will help maintain the property of the drilling mud at very good level, removing the unnecessary large sized solids and protecting the drilling equipment from being damaged by large solids.


We can make a comparison, the mud pump is like the heart of the whole rig, the drilling mud is like the blood of the rig. And the mud recycling system is the key component that will make the heart and blood running healthy and strong. All the GN’s solid control equipment in the mud recycling system is good quality with competitive price. GN’s shale shaker’s G force can reach up to 8 G, which will make the discharged solids drier and meeting the environmental requirement. The new and upgraded shaker screen is also a selling point for GN. We all know that during the drilling process, the shaker screens will be consumed a lot. GN’s new composite screen has even better longevity, better performance and can store longer time than ever before.


More and more customers from Europe and North America like GN’s products and buy more and more GN’s products. GN will continuously work hard to provide customers with the good quality but cost effective products.

As the leading company in the solid control industry, GN solid control can manufacture not only the good quality solid control equipment, but also can make great mud recycling systems. This system is with full stages of solid control equipment and large liquid storage tanks. Since its establishment in 2007, GN has already started manufacturing the solid control equipment for the oil and gas industry. After 10 years development, GN has already accumulated much experience and can be customer’s one stop shop for solid control system. Now its product range spanning from mud cleaner, cutting dryer, shale shakers, decanter centrifuge, vacuum degasser, various kinds of pumps and so on.


The mud recycling system is mainly composed of the following elements: there are 14 tanks in total used for mud recycling, storage and mixing and for water and fuel storage. There are 3 units of shale shakers which will be connected to the mud distributors that will distribute the drilling mud coming through the pipeline from the wellbore. There is also a mud gas separator to eliminate the flammable gas for safety purpose. And after the shale shaker, there is one vacuum degasser which will be used to remove the cut in gas in the mud to improve the efficiency of the centrifugal pump. After that is one mud cleaner which is composed of desander, desilter and underlying shale shaker. One decanter centrifuge is also equipped in the system for barite recovery. This can save the operator a lot of money as barite is very useful and expensive. There are also various pumps installed in the system to perform their function, such as the centrifugal pump which is used to transfer the drilling mud in the system. And there are also about 30 units of agitators and mud guns which will be used to clean the corners of the tank and mixing the mud in the tank to keep the mud property at good level.


That’s the brief introduction about the mud recycling system. Hopefully it will be useful to you. GN has many types of configuration for different mud recycling system for different HP drilling rigs.  Welcome to visit www.gnsolidsamerica.com and please send your inquiries to sales@gnsolidscontrol.com
