During the past decades, China has developed quite rapidly and soon becomes one of the biggest resources consumers in the world. Meanwhile, with the largest population in the world, the long-sight China government put an eye on environment protection quite strictly. According to laws and regulations, all oily sludge must to be treated well before dumping.

 

As a well known brand, GN Solids Control always comes up with professional solutions. Recently, GN just provide to a domestic client in Tianjin a combination of equipment including a decanter centrifuge GNLW454ET and GNSD90 disc stack separator.

1. GNLW454ET is a centrifuge model with 18 inch bowl diameter, and a length diameter ratio of 4. It is a high speed centrifuge with bowl rotation speed up to 3000RPM. Comparing with GNLW452 with 2 as bowl length-diameter ratio and GNLW453 with a ratio at 3, the GNLW454 with a longer bowl could give clearer separation result, especially for the material with higher viscosity, for example, after chemical dosing procedure.

2. GNSD90 disc stack is a 3 phase separator which can separate the oil, water and solids. But it has some limit for solids size input, that’s why before the disc stack there should be a decanter centrifuge for separating out the particles from 2 to 5 microns. After the disc stack, the oil can be recovered to sell for money, the water can be reused in the same separation unit for dilution and the solids particles are easier for future treatment or discharge.

GN has different models of decanter centrifuges and disc stacks for meeting the different capacity requirements. And if necessary, GN could also help to provide the equipment before the decanter centrifuges according to the material condition and requested treating results. Like the shale shaker, chemical dosing unit and preheating mixers.

GN Solids Control is an API Certified manufacturer, and also certified by ISO and HSE. GN Solids Control has its products sold to more than 70 countries in the world. If you need more information or similar project, welcome to contact GN Sales directly for consultance.

As long as there is a drilling project, there must be a solids control system coming along, no matter it is for land rig drilling or offshore drilling far in the oceans, an efficient solids control system are vital for the drilling fluids recycling and drilling cuttings transportation, especially for the offshores.

GN SHAKER

GN SHAKER AND MUD CLEANER FOR OFFSHORE

In offshore projects, cause of the distance from the land, all material must be used to the most, the most liquid should be reused and least cuttings to be transported back to land. The shaker is used for separating out the most of solids, for handling the heaviest burden, the high performance and strong structure of shaker is quite important. Following features of GNZS series shakers ensures the shaker’s quality and performance:

1. A high G force up to 8.5G powered by Oli Vibrator for a good separation work.

2. Stainless steel shaker deck is stronger for handling the high G force.

3. Patent design of rubber sealing, effectively avoided the leaking of mud.

4. Two different models, with 3 or 4 pieces of shaker screens, providing large treating capacity of 120cbm/hr or 140cbm/hr.

5. Special patented way for changing screens, safe and human oriented.

Talking about shaker screens, as is known to all, shaker screens’ quality greatly affects the shaker’s performance. That’s why GN has built up a separate screen factory for better control over screen quality. In this shaker screen factory, GN is the first and only one who uses robot for welding and cutting, and GN’s screens are in accordance with API RP 13C, an accurate API number and a high conductance with a good screen frame structure made of composite material.

For more information, welcome to contact GN Solids Control directly and welcome to visit GN factory at any time.

Just last week, GN Solids Control has finished a compact mud recycling unit, with full steps for separation for one of the largest oil giants in China. This system is to be transported to the jobsite by end of this year.

This system has 4 steps of separation, including:

1. GNZS703F. Shale shakers are always the first step for separation, because of GN shakers’ high G force and accurate API complied shaker screens, this shale shaker can efficiently separate out all particles larger than 100 microns, there in hence to help with prolonging the service life of the centrifugal pump after the shaker.

2. GNZJ703F-1S8N Mud Cleaner. Mud cleaner is a combined machine of desander and desilter, at a smaller foot print. It uses interchangeable shaker screens as GNZS703F, 2 centrifugal pumps are used to feed the desander and desilter respectively.

3. GNSP series Centrifugal pumps are also GN’s own products. For material choosing, GN used the high quality anti-weary material as pump body material by hard ductile iron alloy, and the main pump body is thicker than other manufacturers’. All GNSB series centrifugal pumps are using stainless steel mechanical seals.

4. Tank and skid for above mentioned equipment. Above mentioned equipment are located as 2 blocks. One block is a skid with lifting and anchoring corners just as a 20ft container, and the shale shaker and mud cleaner are located in the skid during transportation and operation. That design facilitates the operator for transportation or lifting the whole skid onto a tank, no to adjust each equipment or pipeline’s position.

5. A tank with compartments are designed to storage the mud from the shaker and from the desander/desilter. On below the tank, there are some slots for installing the centrifugal pumps. The whole outsize of the tank is also same as a 20ft container with container corners for lifting.

Recently, GN just finished another set of solids control system to Australia, which is going to be used for oil and gas industry and now the system is at sea for sailing to Australia. Seldom solids control manufacturers could reach such a high standard of Australia, which are even higher than the USA and Europe. But this system is not the first one. In recent years, GN has provided to Australia 3 sets of oil and gas solids control systems, and more than 30 sets of mud systems for HDD projects.
Besides the normal standards for the oil and gas industries, the Australian market has its specially high standards:

1. For electrical components, including the motors, cables, glands and control panels, all have to meet both IECEX standards and Australia standards.

2. Walkways and guardrails must reach very specific standards, like the max and min distance of gaps. Lifting pads and lifting eyes all have to meet safety standards, and marked with SWL.

3. Walkways and stairs are made of high duty fiber glass, instead of gratings or checkered plates.

4. Higher standards for welding and painting.

Australian companies are quite strict when choosing the supplier and inspecting the equipment. During fabrication and before delivery, there are top management and third party engineers coming to GN Solids Control for checking their orders. They are quite satisfied with GN’s factory management and designing ability of GN engineers.

In fact, GN has more than 10 years of experiences in this solids control and waste management industry and GN was the first API certified manufacturer in China for oil and gas solids control equipment. GN’s products, like the shale shakers, mud cleaners, decanter centrifuges, vertical cuttings dryers, mud agitators and centrifugal pumps are exported to more than 70 countries of the 5 continents in the world. And also GN shaker Screens.

In practice of solids control industry, mostly used shaker types are single deck shakers. But as the development of the allocations, there are fewer desander and desilters to be used, while more and more shakers are being chosen as replacement of desander and desilters by using finer screen meshes. A double deck shaker or a set of double deck shakers could provide both a large treating capacity and a good separating result.

GN Double Deck Shaker

GN double deck shaker

GNZS706F series double deck shakers are widely used in such conditions. It has 2 layers of shaker deck, the upper deck is kind of scalping deck, with 2 pcs of shaker screens, each with dimension of 750mm by 900mm, which is also the shaker screen size of a mini shaker GN Solids Control always makes. The lower deck is same as the most popular model GNZS703 series shakers, using screens with size 700mm by 1250mm, providing a total screen area as 1.35m2 of upper deck while 2.63m2 of lower deck. The upper deck uses coarse screens as the first step of separation, while the second deck uses finer screens to separate out the smaller cuttings. GN could locate them as double-shaker set or tri-shaker set sharing one mud distributor to serve for different treating capacities. Both smaller and bigger screens are made by GN Solids Control, with composite material frame for a larger conductance, longer service life and a safer usage.
By using 2 sets of high G force vibrating motors each of 1.94kw, the double deck shaker has a vibration G force up to 8.0G, and the stainless steel made shaker deck design well endured the high vibration with strong structure.
Besides double deck shaker GNZS706, GN Solids Control has a complete series of shale shakers, including the 2, 3 or 4 screens shakers like GNZS752, GNZS703 and GNZS594. For the latter 2 models, GN also has high-G drying shaker available with hopper feeding and larger G force. Except for the oil and gas solids control, GN shakers are also widely used for HDD, TBM, pipe jacking and other drilling works.
