Mud Gun is designed for users to mix and suspend particles in a solids control system. Mud Gun can prevent the mud from precipitating. It is a very simple tool and easy to operate. It is usually we operate with mud agitator; agitator should place at tank center and mud gun at the tank corners. This will reduce solids build up in tank corners. Size of the tank will determine the number of mud gun to be used.

There are many different designs of mud guns. GN Mud Gun design comes with 3 nozzles. Customer can choose the nozzle size is 2” (DN 50) or 3” (DN80). Also, two styles of the structure, one is fixed (0 degrees) the other is rotary (360 degrees).  Build for tough task purpose GN Mud Gun designed with strong materials with affordable price. GN Mud Gun is the best product to have in your solid control system.  

GN Mud Agitator

Mud agitator usually mounted on mud tank for mix the drilling mud to avoid the drilled cuttings and refined solids from the settlement. Each large compartment of storage tank should be equipped with mud agitators to keep the appropriate drilling mud that will draw out to the borehole.

GN horizontally mounted agitator included an explosion-proof motor, coupled to a gearbox that drives the impeller shaft. The impellers (turbines) transform mechanical power into fluid circulation or agitation. The objective is to obtain a uniform suspension of all solids. Motors range from 4 to 30 HP and Horsepower may be de-rated for 50Hz or 60 Hz power configuration. Available horsepower ratings are: 4, 7.48, 10, 15, 20, 25, and 30.

Why chose GN Mud Agitator? It is lightweight, low noise, explosion-proof electric motor, high efficiency of transmission and strong horsepower agitator.

GN Solids America got Desilter and Mud Cleaner orders to US Customer. GN desilter is the third-class solids control equipment to treat the drilling fluids. According to the size of the cone diameter, they are divided into Desander and Desilter. Usually the cone diameter is less than 6″is called Desilter and used as the third-control equipment in drilling operation. We commonly used 5 “and 4” come to separate solid-phase particle size 15-47μm in the drilling fluid. Based on customer requirements and capacity, we can select groups of cones into Desilter. Our factory and company are Quality Management System ISO 9001-2000 certified. GN Solids Control operates international oil, gas drilling mud separation system from China manufacturer, with good quality product and great price. The GN Desilter machine is a must have equipment to your Solids control system operation.

Desilter is the third stage solids control and fourth stage drilling mud cleaning equipment in the drilling fluids recycling system. GN Desilter commonly adapts 4” cyclone which could separate the solid phase particles with the size of 15-25 microns. GN Desilter is designed 2 options of with and without underflow screen for customers’ requirement.

The desilter with underflow shaker is also called Mini cleaner which is applicable for both weighted and unweighted drilling mud, while traditional desander no underflow vibrating screen only for unweighted drilling fluids. And comparing with large size desander and desilter assembly, the Mini Desander is cost-effective. For the compact mud system used in HDD, CBM, water well drilling and Mining project, Mini desilter cleaner is an Ideal choice.

GN Desilter capacity starts with 528, 156, and 1584 GPM. Desiltier option with 8, 12, and 16 PCS. Feeding size is DN150 and Output size is DN200. Desilter: Cut Point+20 Microns 

The GN Vertical Cutting Dryer uses centrifugal force to dry drilled solids in oil or synthetic base fluids. A stainless-steel screen bowl traps “wet” solid and accelerates them up 900RPM with G force to 420G. GN Vertical Cuttings Dryer specially designed for drilling cuttings from Oil Based Mud（OBM） and Synthetic-based Mud (SBM).

The GN Vertical Cutting Dryer uses FAG Brand premium bearing. The Flights on the rotor is hard facing to HRC 65, longer life than our competitors. Specially designed highly precise stainless-steel screen to ensure your better separation, longer life, and easy replacement. With high-pressure air knife design to clean the basket screen automatically to avoid the screen blinding especially for high viscosity mud and water-based mud. Individual oil lubrication system with automatic alarm for pressure limit. The main motor and oil pump motor is interlocked with each other for avoiding the start of the main motor prior to the start of the oil pump motor. All around flushing system through a specially designed nozzle to avoid the block of the liquid discharge channel. The screen itself is individually balanced for future replacement. And the screen is separated from the frame which allows you to change the screen only, not need to change the frame inside. The flights and the rotor assembly are individually balanced for future replacement. The liquid is forced through the screen bowl openings, while “dry” solids are extracted by the angled flights attached to the cone, which rotate slightly slower than the bowl. Tungsten carbide protects the flights from abrasive solids and ensures long operational life. This aids in maintaining a constant gap between the scroll and screen bowl, which is crucial for proper operation.GN Vertical Cuttings Dryer Centrifuge unit offers a waste management solution to effectively clean and dispose of drilling solids and maximize drilling fluid returns specific to operational needs.

We are very familiar with the process of settlement, where solids in liquid fall down to the bottom of a container, leaving liquid phase crystal clear. This is the case when we sit a cup on top a desk, fill it with water including some solids. After some time the solids will settle at the bottom. Equipment like this is called clarifier.

However, this process happens in natural gravity and it takes too long for the solids to settle down. Then people thought centrifugal force may help to speed up this process. So they tried to tie a bottle on one end of a rope and rotated the rope at certain speed. They found that the settlement happened much quicker. This initiated the decanter centrifuge, which works on the same principle as the rope except that decanter is more complex, withstand more load, and make the settlement process much faster.

With decanter centrifuge the separation of solids from liquid is greatly expedited. For instance it can take hours for solids to separate from liquid while it takes only a few second to achieve the same result. This is because G force generated at decanter centrifuge is a few thousand time that of regular gravity.

There are many factors controlling the performance of decanter centrifuge, but among them the following four factors are most influential.

1. Centrifugal force generated. This determines separation efficiency. When the gravity difference between solids and liquid become very small, exceptional strong G force is need to separate solid from liquid. This also applies to small particles, in the magnitude of microns, as buoyance is in the same magnitude of gravity force an the particles will float in the liquid;
2. Differential speed required to send settled solids from decanter centrifuge
3. Design of screw conveyors
4. Settlement section for particular type of applications.

There are much more considerations in practical applications.

Many people know that decanter centrifuge works on the principle of centrifugal force, which makes heavier solids to settle down on bowl wall and lighter liquid phase to “float” on top of the deposited solids. However, there is much more to take into consideration when decanter centrifuge is to be applied to different applications.

The first consideration is the capability required to in the production process. This can differ tremendously, from a few million liter per minute to thousands of cubic meters per hour. This is mainly due to economic consideration.

The other consideration is the length and diameter of rotating bow. The longer the rotating bowl, the longer slurry takes to travel the whole length, and therefore better settlement of the solids. This is particularly important when lighter solids phase is to be separated from the liquid. If the solids is much heavier, such as barite in drilling process, bowl length does not need to be that long. It is common for the length of rotating bowl to be 2, 3 or even 4 times the diameter of rotating bow.

Another consideration is the conical section of decanter centrifuge bowl, this concerns the texture of the solids to be separated. If solids is easily compactable, a bigger angle can be applied so as to increase throughput speed. However if the solids to be separated is quite lose, and difficult to get compacted, a gentle angle is usually required to have them compressed properly before being discharged from the rotation bowl.

One important factor is the centrifugal force. There is much to consider when this factor is to be considered. In a slurry there is always liquid in between solids particles. The finer the solids particle is, the more liquid content, therefore a much larger centrifugal force will be needed to move liquid content out from between solids particles.

Drilling activity is the process to establish communication channels for oil and gas to rush up to the ground. There must be a big number of mud tanks to support the normal progress of oil and gas drilling. Usually these mud tanks need to be cleaned, to prevent cross contamination, to prepare the tank for inspection, or simply for storage.

This task is usually done by people. Workers will wear heavy protective clothes, and use respirators, to go down inside the mud tank to clean the interior of mud tanks manually. As there is no lighting in the tank, illumination is required as well. As drilling technique is getting more and more complex, a lot of chemicals are added to drilling mud. These chemicals may be a serious thread to the workers. Confined space, potential toxic material (liquid or gas), dim environment, high temperature are big risks to people exposed to it. This inevitably give tension to people’s psychology and impact work efficiency adversely.

GN Solids Control has been involved in finding a good solution to get rid of this problem. After years of research and development work, GN Solids Control worked out the first generation of automatic tank cleaning system a few years ago. People at drilling rigs gave high appraisal to this system as it released them from difficult and dangerous cleaning environment. They also pointed out issues with the application of the system, which helped GN Solids Control to continue its R&D to make the system better.

Recently GN Solids Control released its third generation of automatic tank cleaning system. Compared to previous generations, the new system features the following:

1. High efficiency. The new system can clean a mud tank in 20 minutes. Compared to 6 to 9 hours needed to clean a mud tank by 4 people, the new system only requires at most 2 people. This increase mud tank cleaning efficiency substantially;
2. It minimizes worker’s exposure to difficult and confined space. All system operation needs to do is to mount the cleaning head inside mud tank and all other work will be done automatically. Some clients of this system have huge number of mud tanks to clean. They use top cover mechanism to lower cleaning head into mud tanks. This eliminates the exposure of people to risky environment.;
3. Water consumption is minimized. Water is valuable, especially in remote area where drilling rigs are located. Drilling rigs often have very limited water supply and do not want to use their water, which is usually trucked in from far away. Manual cleaning used open loop process – flushed down slurry will be dumped and the water is wasted. This new style automatic tank cleaning system contains solids-water separation equipment, which can settle solids down efficiently and reuse the water for cleaning. It significantly reduced water consumption, the quantity of slurry dumped to the environment, and the cost to truck the slurry to recycling station & to truck in fresh water;
4. New technology increases solid/water separation efficiency. This system can provide high flow rate to provide enough cleaning media and good pressure to wash mud tanks. If natural settling technique is used for such high flow rate, separation result can not be guaranteed. GN Solids control uses new technology which can separate solid from the slurry effective and efficiently and return clean water back to the cleaning head. Field experience shows that most of the solids are separated from slurry and cleaning quality is well secured;
5. GN Solids Control also uses other new technology to transfer slurry from mud tanks to the cleaning system, which can not be achieved by routine technique;
6. Automatic control. This system can also automatically control system operation to prevent dry suction or tank overflow.

There are other new technologies GN Solids Control uses to make the system do its job as is intended. Please contact us for more information and solutions for your tank cleaning needs.

There is always the need to transfer material other than liquid from one place to another. Examples are everywhere, from coal mine to construction side, from steel mills to agriculture.

There are many ways to transfer such material as well, from trucking, to tanking, etc., featuring high cost and low efficiency.

There is limitation for the above means of transferring non-liquid material too. For instance, transferring coal bring the potential of environment contamination. Other means of the movement of such materials is in bad need.

Vacuum pump manufactured by GN Solids Control solves this problem.

GN vacuum pump can transfer sludge, solids particles ( no more than 50mm or 75mm in size) to locations up to 1000m from pump location.

GN vacuum pumps uses venturi pipe to generate vacuum, and sucks sludges from tanks, pits, etc., and sends them to the closed buffer tanks. After a pre-set material level is established inside the buffer tank, the vacuum pipe will stop sucking and compressed air is applied into the tank to force the material inside the buffer tank to go outward. Because the high pressure of the compressed air, sludges can be transferred a long distance.

The advantages of GN vacuum pump are:

1. Safety. For instance mine camp waste can be safely transferred by vacuum pump. Other material such as life sludge can be transferred without affecting the health of the operator;
2. Environmentally friendly. Because the complete sucking & discharing & transferring process is done in a sealed pip route, no material is being leaked out from the route and there is no contamination to the environment;
3. High efficiency: GN vacuum pump has the capability of 10m³/h, 20m³/h and 40m³/h without the assistance of other machinery;
4. Flexibility: GN vacuum pumps can be used to transfer sludge, liquid, solids, tail mine, construction waste, from tanks, pits, river, etc., almost from any locations;
5. Versatile. Such pumps can also be used as a mobile equipment. It can be mounted on a truck, on a boat. For instance, it can be mounted on a vessel, suck up a dredge in a water surrended location, and transfer the dredge to the land.

GN vacuum pump has great potential in industry and daily life. If you have want to know more about this vacuum pump please visit www.gnsolidscontrol.com.

On drilling site there are many mud tanks for the normal drilling operation. Mud tanks are not high tech, but they are indispensable.

When drilling rigs need to switch from one kind of mud to another, mud tanks need to be thoroughly cleaned so that drilling muds would not crossly contaminate.

Traditional tank cleaning method is manual. Workers with heavy protection clothes enter mud tanks, exposing themselves to the hazardous enclosure and apply high pressure solution spray to clean mud tanks. This process is tedious and labor intensive, in hazardous environment. Sometimes the drilling rigs are in urgent of clean mud tank, and the only way to speed up is to clean the mud tanks with more workers, which adds economic burden to drilling operation.

In order to solve this problem, GN Solids Control performed extensive research, and in-depth development work. The result is GNTC-30 series automatic tank cleaning system.

The system composes of a buffer tank, which stores cleaning solutions. A powerful centrifugal pump pressurizes the solution and send liquid to tank cleaning machine (TCM). TCM is a well-engineered sprayer, which can scan the inside of mud tanks at pre-set scanning pattern. Usually tank cleaning is finished with one complete scanning cycle. If super clean inside is needed, say for very expensive drilling mud for critical drilling, secondary scanning is deployed.

Suck pump will collect fluid on the floor of mud tank and transfer the fluid to a inclined plate clarifier(IPC) by GN Solids Control, through a filter, which stops big items such as screws, big drilling cut from entering such pumps. It is quite normal that a lot of barite would deposit on mud tank floor. Because of its cost, barite needs to be recovered. So suck pump should be able to transfer heavy barite.

Once the sucked-in liquid is transferred to IPC, this highly efficient clarifier quickly separate solids including barite and solution. Solids will go to the bottom of IPC. Clarity of solution increase with decrease in liquid depth, with the cleanest water on the surface of liquid. This clean water will overflow to buffer tank, to be pumped again to clean mud tank to establish closed loop system.

The IPC by GN Solids Control has specially designed shape, which allows quick establishment of solids inside the tank. A membrane pump will transfer the deposited solids, including barite, to collect bin.

One major advantage of such automatic cleaning system is its efficiency. In general, a mud tank can be cleaned in 30 minutes. This is much more efficient compared to the manual cleaning process, which usually takes hours of hard labor work.

Another advantage of such system is safety, because exposure to hazardous enclosure is minimized. Operators only need to enter mud tanks to setup cleaning machine, and the rest of the cleaning process is done by the machine, with operator working on the outside.

GN Solids Control is continually to developing more efficient, more intelligent automatic mud tank cleaning system for different applications.
