GN Dewatering Unit with Flocculation System
As the fast development of GN Solids Control, GN has provided many sets of solids control systems to clients from various industries. Recently, GN got many inquiries on waste water management, some clients need to separate the clean water from drilling mud can d reused the water.
Although different projects are customized by different working situations, the working principle is pretty the same. Just take one of the dewatering unit that GN Solids Control provide several months before as an example.

This GN Dewatering Unit is composed by the following equipments:
1. GN Double Deck Shale Shaker
It’s used to separate solids that larger than 100 microns. Here we use GNZS706E-HB.
2. GN Desander
Desander is one type of shale shaker with large cylones, which can be used to separate solids larger than 50 microns. Sometimes, GN recommend to use desilter which is equipped with small cylones and can do much finer separation.
3. GN Flocculation Unit
The flocculation is used to add polymers into drilling fluids which can help to collect small diameter solids.
4. GN Decanter Centrifuge
The drilling fluids come from flocculation tank can be further separated by GN decanter centrifuge, which can separate the solids larger than 2 microns.
So after all the treatment by the above solids control equipments, clean water can be separated from drilling fluids or waste water and this clean water can be reused. For some strict demands, such as the discharged mud need to be pretty dry, GN Solids Control recommend to use vertical cuttings dryer.
By using GN vertical cuttings dryer, clients can deal with oil base mud (OBM), water base mud (WBM) and synthetic water based mud (SBM). GN has provided many sets of cutting dryer for mud separation. Based on the working performance, the oil can be separated to below 5% and the water can be separate to below 10%. For details, welcome to contact thomas@gnsolidcontrol.com.

Lately, Hebei GN Solids Control Co., Ltd, a specialist of drilling waste management system, has arranged the shipment of 1 unit of drilling cutting drying equipment to the West African customer. GN solids control is the first API solids control and drilling waste management equipment manufacturing company in China, and it has sold items to in excess of 60 nations. This isn’t the first order but a repeated order following the customer using GN product. Using the passing of environment rules, just about all drilling cuttings have to be dried to lessen pollution before discharge.

 The order that the customer required about the equipment shows up as below.

 1 unit GNCD930 vertical cutting dryer having a maximum speed of 900 Revolutions per minute along with a maximum G force up 420 centrifugal G force.

How to choose GN decanter centrifuge based on rotating speed

GN Solids Control Co. has been working on solids control and drilling waste management systems for many years, there are clients from over 60 countries are using GN products. With the fast development, GN moved to the new factory near Beijing several years ago, and GN has been building another factory which is quite near the current factory.

Last year, GN has established two branch companies in America and Russia, GN is working on the storage of solids control equipments and spare parts in these two branch companies. Right now, GN Solids America has 4 shale shakers, 2 mud cleaners, 2 decanter centrifuges in Houston warehouse, some other spare parts are also kept here.

As GN decanter centrifuge is quite popular, we have sold about 250 sets every year. Today we would like to give you some brief introduction on how to choose GN decanter centrifuge based on the rotating speed. The rotating speed as well as differential speed is quite important for the performance of decanter centrifuge. The largest rotating speed is not always the best solution.

1. For barite recovery, you can use GNLW452 at the rotating speed of 1800 RPM, while for GNLW363 you can use 2200 RPM fix speed.

2. For high gravity solids separation, we recommend to use GNLW452 or GNLW363 at the rotating speed of 2700 RPM. If equipped with cuttings dryer, you can use GNLW363 with 2700 RPM pulley.

3. For low gravity solids, we recommend to use GNLW363 equipped with the 3200 RPM pulley.

4. For solids control system, one set of GNLW452 and one set of GNLW363 is totally OK, the rotating speed can be 2700 RPM or 3200RPM.

5. It’s obvious that you can choose variable speed decanter centrifuge if you are not very clear about the solids condition. And you can change the rotating speed quite conveniently when the solids condition is changing at the same time.

GN Solids America LLC has been in TX for nearly two years. With the large help from GN Solids Control (Chinese headquarter), GN Solids America is acknowledged by more and more oil and gas companies.
GN Solids Control has many experienced engineers that working on solids control for many years, and GN has provided many sets of whole project solutions for global clients.

GN Hi-G Shale Shaker and GN Vertical Cuttings Dryer for Shell
GN Solids Control has provided many sets of solids control equipments and drilling waste management systems to worldwide clients. These years GN has gained many successful experiences in drill cuttings managements systems.
Take one tailored set of drill cuttings managements systems for Shell as an example. This system is combined with one shale shaker in linear motion and vertical cuttings dryer work under vertical G force. For this cuttings management system, it can move in the linear motion and vertical motion.

This system mainly including:
1. GN Cutting Dryer
GN930C-VFD can treat drilling waste 30 T/H to 50 T/H, the effective treating capacity is around 35 T/H. Rotating speed is adjustable with 900 RPM. Now GN cuttings dryer is the only one in China can handle OBM and WBM at the same time. GN cuttings dryer can handle with synthetic base mud. Now GN Solids Control manufactures about 60 sets of cuttings dryer every year.
2. GN shale shaker
GNZS594HGE-LD shale shaker is especially designed for drying cuttings. The vibration G force is upto 8 G when working.
3. GN mud tank and pumps
Here we use two mud tanks, the shale shaker and cuttings dryer can be fixed in these two mud tanks separately. There are some other auxiliary parts such as feed pump and flush pump.
The working process of this system:
All the drilling cuttings must be separated by shale shaker in advance, then these solids will be transferred by screw conveyor to GN cuttings dryer. By using GN cuttings dryer, most of the fluids will be separated out. The screen opening of our cuttings dryer is about 0.25mm to 5mm. Then the fluids will be feed to GN H-G shale shaker, here it will make the further drying work.

Sometimes, the drilling fluids can be sent to GN H-G shale shaker directly without the vertical cuttings dryer. However, in order to reuse the drilling fluids, all of the above fluids from vertical cutting dryer or H-G shale shaker must be treated by GN decanter centrifuge. Only in this way, we can get separated the solids that larger than 5 microns.

Mud Recycling System for Core Drilling and CBM Drilling
GN Solids Control has provided many sets of mud recycling system, some of these solids control systems are designed and manufactured on customers’ particular demands.
Take one set of mud recycling system as an example, GN has provided a double function solids control system for core drilling and CBM (coal bed methane). Usually, there are large differences between core drilling mud system and CBM mud system due to these two drilling methods needs different amounts of drilling mud.
For core drilling, the mud system is usually has the treating capacity of 50 GPM, while for CBM drilling, the treating capacity of mud system is reach to 500 GPM.
And the separating demands of core drilling and CBM drilling is not the same, either. Generally speaking, the diameter of solids from core drilling mud system is less than 20 microns; on the other side, the solids’ diameter is usually larger than 20 microns.
This mud system including the following equipments:
1. Mud Cleaner：
GN mud cleaner is composed of dual layer shale shaker and desilter. The type is GNYZ 703E-8N, it has 8 hydro cyclones which are made of PU.

2. Mini Decanter Centrifuge:
The type is GNLW223. It is one baby decanter centrifuge that is designed especially for diamond core drilling.

3. Feed Pump:
Using Nemo pump to feed the decanter centrifuge, this pump is a positive displacement type which can avoid agitating when feeding. There are also some other centrifugal pumps that used to feed the desilter, as well as some pumps worked together with mixing hopper on mixing tank.
4. Mud Agitator:
For the mixing compartments, there are several mud agitators located on the tank, GN mud agitator is one cost-effective type for mud agitating.
5. Mud tank:
Here we use one mud tank with the length of 8m. All the above equipments can be fixed on this mud tank.

GN Solids Control Co. has developed many different types of solids control equipments that can be used on oil and gas industry. And GN is a very large company who can provide turn-key solids control or waste management systems for global clients.
As we all know, the oil in Canada is mainly exists in oil sands which is also called tar sands. According to the latest survey, more than 98 percent of the oil sands and conventional oil are in Alberta. If we just considering the oil reserves, then Canada would be the third largest oil country.

                           GN Vertical Cuttings Dryer
For conventional oil, there about 39 percent in Alberta, we have already known that explore and produce oil from this conventional energy. GN has provided many sets of turn-key solids control systems for world clients. Until now, COSL has used four sets of GN 1000 GPM solids control system. And GN has also provided four sets of 1000 GPM mud recycling system for Russia client.
So for this conventional oil, GN has a large room to cooperating with drilling company from Canada. And for the oil sands, depends on the exploring and producing processes, GN Solids Control can provide different equipments.
There are two ways to explore the oil sands:
1. The first way is using excavators, the surface oil sands can be can be dig and transferred to a truck, and transported to a treating and refinery factory. This cost of this way is relatively low, but the damage to lands is very large.
2. The second method is called “SAGD”, which means steam assisted gravity drainage. The other processes are quite the same as explore the conventional oil.
GN Solids Control equipments and drilling waste management systems can help to get the bitumen and protect the environment at the same time. Many solids control equipments such as decanter centrifuge, cutting dryer can be provided by us. And we also have mini decanter centrifuge, which is especially suitable for core drilling or diamond drilling.

GN Mud Guns for agitating
GN Solids Control is one of the largest companies in China to provide turnkey solids control solutions in oil and gas industries. During the past years development, GN Solids Control has already become a world famous brand in the solids control field. With the development of GN Solids America LLC and GN Solids Russia, GN will have the chance to service more and more clients, and right now GN solids control and drilling waste management systems have already been used in over 60 countries.
GN is a company that can provide whole solids control project to customers, and on the other side, GN Solids Control is manufacturing various kinds of spare parts such as mud guns, centrifugal pumps, shear pumps, submersible pumps etc. Some of these spare parts are sell very well, and after the clients have used GN solids control spare parts for a while, they come to GN for turnkey solutions because they already have the confidence about the excellent quality of GN solids control and drilling waste management systems.

Today we would like to give you a short introduction about GN Mud Guns. As we all know, GN mud guns are used for flush the corners of the fluids in mud tanks, and they are usually working together with mud agitators. When a mud agitator is keep the solids rotating in mud tank, the mud gun can help to work on the corner due the large working pressure.
There are two common types for GN mud guns, one is a fixed type (which means the mud gun is fixed on a mud tank and can only work for the specific angle), the other type is a rotating one, the mud gun can rotating by adjusting the hand lever on the top. Usually, we recommend customers to use rotating type, although it is a little expensive, it is quite convenient to use. The working length of mud gun shaft can be decided by the height of tank.

A total drilling rig system usually contains drilling floor block, mud solids control block and recovery, mud pump and power block. Concerning these, the mud solids control and recovery block is composed of drilling mud recycling and drilling waste cuttings system. This block can be used to maximally recover the valuable drilling mud as well as decrease the waste discharge. 

The drilling waste cuttings management system occasionally called the further treatment method for solids control. Since the cuttings was delivered from out interface of the primary solids control equipment like shale shaker and mud cleaner towards the cuttings dryer device. The principal equipment for drilling waste cuttings recovery consists of cuttings transferred equipment, Verti G cuttings dryer, feeding pump and decanter centrifuge.

The cuttings transferred devices is being regarded as a bridge connecting the primary solids control system to the waste management unit. The typical and well-liked approach to transfer the cuttings is to utilize the screw conveyor and hose pump.

What is the Difference of the screw conveyor and hose pump

The screw conveyor itself has a gathering groove and the screw propeller push the cuttings to the Verti G cuttings dryer. Since the screw conveyor is engineered to shift the cuttings around an upright line. Usually, on the spot, there are not just 1 unit screw conveyor, several unit screw conveyors are situated crossing with certain angles so as to the waste cuttings can be delivered to the cuttings dryer. While the cuttings dryer feeding port is high, the screw conveyor is sloping. Subsequently if the waste cuttings are high liquid content, the liquid might be regurgitate and overflow off the conveyor.

The hose pump is a new, multifunction and multipurpose industrial pump. There is a particularly made rubber hose with smooth inside and high strength installed in the pump body. The hose pump has a exclusive structure with no sealing aspect, no leakage and no pollution. It has a high suction capability, self-cleaning capability, sucking material in two instructions. The hose installed in quite simple and operation is effortless, and the maintenance charge is low. The most essential is no block when pumping fluid with high viscosity and foreign substance content.

The drilling waste cuttings transferring equipment is important throughout the operation. GN Solids Control has applied both of the screw conveyor and hose pump in the design of the drilling waste management system, for more information and facts, please get in touch with GN freely.

GN Screw Conveyor
As the established of GN Solids America, GN is beginning to known as a famous solids control company from China. And with the excellent quality and good performance, GN solids control equipments are welcoming more and more clients in North America to our Houston warehouse. Some clients prefer to see these solids control equipments first and rent for trial use.
We believe as the days went on, GN will become a leading company in solids control and drilling waste management in the sooner future.
Today, we would like to give you a brief introduction about our screw conveyor (which is also known as auger). GN Solids Control has provided many sets of screw conveyors every year for worldwide customers.
For the screw conveyor, it is mainly used for transferring mud or solids, when it contains too much water, we don’t recommend using conveyor.
GN has some different types, from conveying capacity 20 tons per hour to 45 tons per hour. All these capacity can fulfill the general demands of mud transfer.

Sometimes, we have one screw conveyor with V type collection box. There are some flanges with pipes on the V type collection box. This kind of screw conveyor is especially used for oily sludge transfer. The quantity is different due to the length of screw conveyor.
Flanges and pipes on the V type box are used for providing hot steam, so the oily sludge can have a good flow ability. There is also one beam across this conveyor, it is used for distributing oily sludge to the two ends.
There is also one type of screw conveyor with heating system, which is equipped with pipes under the cylindrical part of conveyor. And this type is mainly suitable for cold environment. Lately, we also provided some set of these screw conveyors with heating system to Russia clients.
