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.

Besides the shale shaker and mud cleaner, there is another block for the dewatering centrifuge, please contact GN Solids Control for more information or wait for next week’s blog.

It is a common knowledge that in the solids control system for a drilling rig, no matter for the land rigs or for the offshores, the shale shaker plays the most important role for separating out the solids waste from the mud recycling unit, and it is also the shale shaker which waste the most of the liquid on the cuttings discharged from the shaker. That’s why, in many countries, there is a must to equip another drilling cuttings treatment system alongside the rig.
A drilling cuttings waste management system is used for further separation of the drilling waste discharged from the shale shaker and mud cleaner, most of which are from the shakers. For one thing, the drilling cuttings waste management system helps to dry the cuttings for later transportation, on the other hand, it increased the drilling liquid amount to be recycled. Both are saving money. In case of OBM mud, the operators always need a vertical cuttings dryer and a high speed decanter centrifuge, while for WBM mud, operators always use a high G drying shaker and a decanter centrifuge.
In some cases, the ViST Shaker screen device could replace the drilling cuttings waste management system, or at least to some degree, reduced the work for the cuttings separation works. Generally speaking, the ViST shaker screen device has following advantages:

ViST shaker device

1. It is suitable for both WBM and OBM mud in a solids control system.
2. It is a compact structure, and only use an air compressor as power source, and one set of ViST could serve up to 3 sets of shale shakers.
3. It is designed to be suitable for different shaker models.
4. In practice, it helps to save the liquid amount by 30% to 50%.
Now for GNZS703 and GNZS594 series shale shakers, there are ViST device for option.

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.

Centrifuges are quite popular in separation industries, in oil and gas solids control, in drilling cuttings waste management, and in oily sludge separation projects. It is perfect solution for separating out particles from 2 microns to 5 microns. The centrifuges are playing more and more important role. But still, it is more difficult to operate the centrifuge well and let the centrifuge to work more efficiently.

GN HIGH SPEED CENTRIFUGE WITH SKID

GN HIGH SPEED CENTRIFUGE WITH SKID

There are some suggestions to help improving the centrifuges’ performance:
1. Before using the decanter centrifuge, make sure the material which enters the centrifuge are not so big for the centrifuges, in order to avoid blocking of centrifuges. For instance, a high speed centrifuge is capable to separate out particles from 2 microns to 5 microns. In practice, particles no larger than 2mm could enter the centrifuges. So it is suggested to use a shaker unit before the centrifuge.
2. How about when the particles are too small? When there are so many extra fine particles, it would be difficult for the centrifuge to separate the particles out. In this case, a chemical dosing unit is invited before the centrifuge. By adding flocculant into the material, the extra particles flocculate into bigger ones in order to be separated by centrifuge.
3. If the material is of too high viscosity, some polymers fed by the chemical dosing unit into the material, to lower down the viscosity. Then the separation result would be much enhanced.
4. Confirm the material content before choosing a suitable bowl rotating speed and a suitable differential speed. The material content information includes: solids content percentage, the distribution of each particle size, and etc. Such information helps the operator to adjust the centrifuge parameters.
GN Solids Control is quite professional in centrifuge design and manufacturing, GN centrifuge sizes range from 9 inch bowl to 30 inch bowl. Pls contact GN for consultancy.
