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.
