Vacuum Degasser

This week GN solids control finished production of vacuum degasser and mud cleaner for clients in Middle East.


We have 3 types of degasser for oil & gas drilling industry, vacuum degasser, centrifugal degasser, mud gas separator. The mud gas separator is installed before the solids control system trip tank, to separate the hazardous gas from the drilling fluids and prevent it from kick off. The vacuum degasser and centrifugal degasser is used after shale shaker and behind desander, desilter or mud cleaner, the function is to separate the gas from the gas cut mud and protect the next process equipments like centrifugal pump, and keep the balance of the drilling fluids, their function is same, just vacuum pump is installed horizontally on the tank top, the centrifugal degasser is vertically installed in the mud tank , it can save space on the mud tank.


The mud cleaner produced by GN solids control is a combination of desander cone, desilter cone and bottom shale shaker. With different qty of hydrocylones, there are different treating capacity for option. The desander cone, desilter cone material are 100% polyurethane which is wear resistance material. The bottom shale shaker equipped with 4 panel shaker screens, with composite material frame for longer working life. Centrifugal pump #1feed the mud from degasser tank to desander cone, the clean fluids dropped into the desander compartment, the solids are separated out and drop down to bottom shale shaker, the useful fluids will be collected and the drier solids are separated out from shaker screens. Centrifugal pump #2 feed the mud from desander compartment to desilter cone, the clean fluids dropped into desilter compartment, which is clean fluids can be reused to prepare for new fluids or can be reused directly.
For more information about vacuum degasser and mud cleaner, pls contact with GN solids control.

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.
