#desilter

An Industrial Control equipment Panel is defined as an assemblage of systematic, logical and fashionable preparations of or greater ingredients like a motor controllers system from aipusolidcontrol.com. The fused disconnect switches, overload relays, circuit breakers, manipulate gadgets with push button stations, and manipulate relays are normally included in this type of equipment.

Control Equipment With Desander And Desilter

Desander and Desilter's difference The diameter of the hydrocyclone's upper parts is the important factor which decide the hydrocyclone's treating capacity and separation size. The diameter of the cylinder is called the nominal size of the cyclone. The lower cone part's angle is between 15-20 degrees. The diameter of underflow mouth is 10-30 mm. Generally, a group of hydrocyclones which nominal size is 150-300mm, is called Desander. And a group of hydrocyclones which nominal size is 50-125mm, is called Desilter. (1) Hydrocyclone desander

With more and more co-operation between China government as well as Russia Government, there additionally more and more cooperation between Tiongkok companies and Russia businesses. As China leading companies in China, GN Solids Control LLC have more and much more development in Russia. Right now the world economic environment is not great, industry companies becomes increasingly more difficult under this circumstances. Many companies, even many large and famous companies as well as cannot survive at the poor condition. But GN Solids Control can keep improving as well as developing. With the advanced style equipment, reliable and quick services, and international solutions net, GN Solids Control get more and more marketing discuss from the international market. Lately, 4 sets solids control shale shaker as well as four sets solids control mud cleaner dispatched to the slot for Russia clients. It is far from the first time the clients purchase from GN Solids Control Organization. But GN Solids Control is the first suppliers with this client from China. Before purchase the solids control equipment supply by china manufacturer, the clients only purchase big equipment from America and European.

Recently GN solids control shipped 4 units of shale shaker and 4 units of mud cleaner to Russia,  we’ve got a lot of big orders since 2015 for solids control equipments and drilling waste management in Russia. Even though the oil price keep in a low level, and the project is very slow, only the companies who keep improving the technology and provide good quality equipments and service could win the order.

For oil drilling industry, we provide 3 models shale shakers for different applications. 4 panel shale shaker GNZS594E-HB , 3 panel shale shaker GNZS703E-HB and double deck shale shaker GNZS706E-HB ( 6 panels with 3panels on top and 3 panels for bottom). We can provide vibrators with IEC ex certificate, ATEX, DGMS( for India only) and China explosion proof with Italy Oli, Itavibras or Martin brand. GNZS594E shale shaker could be also used as high-G dryer shaker for water based mud drilling cuttings treatment. GNZS706E-HB shale shaker with top screen deck ( scalping deck) and bottom screen deck ( screening deck). All the shaker models could be made as tandem shale shaker or dual tandem shale shaker for convenient move.

Combination with different numbers of desander cone qty and desilter cone qty and the 3 models shale shaker, we could provide different treating capacity mud cleaners, you can choose with only desander cone as desander unit or with both desander & desilter as mud cleaner or only with desilter cone as mud cleaner. Compared with the desander & desilter without bottom shale shaker, the mud cleaner bottom shaker could recycle more useful drilling fluids and separate the drilling cuttings much drier.

Cuttings Box Used on Drilling Site

Cuttings box is also called cuttings collection box that is widely used on drilling site as a temporary vessel to collect and store the drilling waste cuttings. Due to the purpose of the cuttings box, it is designed compact and easy for transportation. Once the cuttings box is full, it could be replaced by an empty one.

The cuttings box is always used on the drilling site where the mud pit is not available. In the solids control system, the cuttings boxes are always located under the solids discharge chute of the shale shaker to collect the cuttings out of the primary shaker. Same situation as the cuttings box located with the de-sander, de-silter and decanter centrifuge.

Most of the cuttings boxes are simple without a cover. And if you want move it, you need be careful as the cuttings still with large content liquid will splash out. With consideration on this, GN Solids Control designed a type waste cuttings box with a fully sealed cover on it. When collecting the cutting, the cover is open; when transportation, the cover is locked easily to prevent the splashing of the cuttings. It is an ideal container to meet the requirements of HSE regulations for hazardous waste movement. Not only for waste cuttings, also for some other hazardous waste discharges. At the bottom frame of GN’s cuttings box, the forklift loading grooves are designed for easy moving and replacing.

Linear motion shale shaker is the first step solids control equipment, and it is the base separation machine for oil and gas drilling rigs. Shale shaker is a D100 separation machine. D100 means 100% separation. The particles over the separation point can be fully removed after going through the shale shaker screens. Shale shakers will be placed on Sand trap Tank. In the normal conditions, clean mud from shale shaker will fall down to the sand trap tank. We also call it shale shaker tank or shaker tank.

Desilter, which is another kind of solids control equipment for treating the drilling fluid. In this article, we will mainly introduce the Desilter made by GN Solids Control. 

Actually compared with the desander, the desilter has the same working principle, similar structure and different configurations for customer option.

Usually desilter is matched together with the shale shaker and desander and used for doing the 3rd-stage separation with the drilling fluid. 

Most of the big sizes of drilling cuttings over 40μm will be separated after being treated by the shale shaker and desander. In next step the drilling fluid goes into the desilter and most of the solid particles over 20μm are separated out from the fluid and the drilling fluid become much more clear. 

The main part of desilter is also the hydrocyclones, but the size is different with the desander’s. Each hydrocyclone used on GN’s Desilter are 4 inches and its standard treatment capacity is 20m³/h. Usually 8 units, 12 units or 16 units of hydrocyclone are standard configuration on GN’s Desilter, the corresponding standard treatment capacity is 120m³/h, 240m³/h and 360m³/h. It is also customized and the customer could choose specific quantity of hydrocyclone for different treatment capacity. 

In this article, we will mainly talk about the desander’s working principle. 

Desander, one of the most widely used solids control equipments used on treating the drilling fluid. 

As we know, with the drilling fluid circulates the drilling cuttings chipped away by the drilling bit continuously when the drilling rig is working, the different sizes of drilling cutting goes into the drilling fluid and the physical properties of drilling fluids will be changed, such as the density, viscosity, solid content, etc. The drilling fluid could not meet the further work demand. 

In order to save the cost and protect the environment, in most of the time the drilling fluid needs to be recycled. Now the Desander and some other necessary solids control equipments like Shale Shaker, Desilter, Decancter Centrifuge will be worked together for treating and cleaning the drilling fluid. By through treating the drilling fluid, the different sizes of drilling cuttings will be separated out and the physical properties of drilling fluid will be recovered.

According to the technical design, the Desanders made by GN Solids Control company are usually used for separating out the solids particles over 40μm in the fluid loop. 

Normally the desander is used for doing the 2nd-stage treatment with the drilling fluid that after the 1st-stage treatment by Shale Shaker. The main part of 1 desander is the Hydrocyclone. Its work principle is as below,
