In last blog, we introduced the shale shaker and mud cleaner in a compact mud recycling system produced by GN Solids Control for the SINOPEC. In this system, there are in all 4 steps of separation, with the first step as shale shaker, second step as the mud cleaner with 1 of 10 inch desander cone and 8 of 4 inch sized desilter cones. The dewatering centrifuge is the fourth step separation for the fine particles left in the liquid.

Why need a decanter centrifuge?
Till now, the decanter centrifuge is a second to none choice for choosing out the particles in the drilling mud between 2 to 5 microns. Even for finer particles, the decanter centrifuge can handle them by adopting a chemical dosing or so called flocculating unit.

How to choose a suitable centrifuge?
1. First of all, to choose a suitable size of centrifuge, the diameter of a centrifuge determines the treating capacity of a centrifuge. In this project, the end user chose GNLW363-VFD, with a 14 inch bowl diameter while the speed is typically 3200RPM, which is quite popular in drilling solids control and drilling waste management applications. Besides this most popular model, GN has centrifuges from small size as 9 inch bowl to big size up to 30 inch diameter bowl.
2. The centrifuge bowl diameter ratio determines the particle size to be separated out, for example, the longer centrifuge is, the dryer solids come out. Among GNLW centrifuge models, there are bowl length diameter ratios for option from 2 to 4.
3. And the higher speed a centrifuge has, the finer particles to be separated out. Per different speeds’ range, there are middle speed centrifuge and high speed centrifuge. Normally a middle speed means around 1800RPM, for example as the big bowl centrifuge GNLW452, with a typical speed as 1800RPM, and a bowl of 18 inch diameter, which is mostly used for barite recovering in a solids control system.

Welcome to send your project information to GN for more professional suggestions.

As the leading manufacturer of solids control and waste management equipment and also a professional separation solution provider, GN Solids Control has a products line covers the separation procedures and also the transferring procedures. GN Solids Control provides various pump for different applications including following:
1. Centrifugal pump, centrifugal pump is the most commonly used pumps in the oil and gas solids control industry, which is used for feeding the desander and desilter cones, for compensate the mud loss from the trip tank as trip pump, feed pump for the mud mixing unit for the mixing application and also plays as a role of charging pump. GN Solids Control produces the full range of centrifugal pumps from75kw to 7.5kw, equipped with mechanical seal, with high quality material for longer service life. All parts of GN series centrifugal pumps are interchangeable with Mission Magnum.

2. GN shear pump. Shear pump is not so commonly used as centrifugal pump. They are only used for shearing some special chemicals which are needed for large horsepower oil and gas drilling rigs.
3. Submersible Slurry pump. Submersible slurry pump’s applications in GN solids’ mud system and mud units are mainly those two: one is for centrifuge feeding in solids control systems like for the barite recovery and extra fine particle separation, or for the HDD mud recycling units, it is the second to none choice for transfer slurry from the mud pit to the mud system.
4. Vacuum pump. GN series vacuum pumps are the newest member among GN pumps. But it gained highest attention ever since its birth. Comparing with other pumps, the most obvious difference is that it has no motor. It is fully air driven and has less limitation for the solids size. In practice, it could handle material with particle size only a bit smaller than it’s pipeline diameter.

Each year, GN Solids Control produces and provided more than 200 sets for shale shakers for drilling rig solids control systems in more than 70 countries and regions in the world. Some equipment are exported together with GN’s system, some are exported separately to replace the old ones for existing system, or when clients are building tanks locally.

GN Shale Shaker System for Australia
Recently, just in last month, GN Solids Control has shipped a complete mud solids control system to an Australian drilling company, and this system now is approaching the destination port in Australia, and is schedule to be put into use in early March. Besides the basic functions a solids control system could provide, this system for Australia must meet some extra requests specific to Australia and New Zealand projects, like the cable laying rules, the distances between each stair and etc. GN Solids Control has an engineer team with rich experiences and a strict QC department to survey the producing procedure and final products, that’s why clients are always happy with GN. In the past years, GN has provided to Australia and New Zealand many systems, including but not limited to following typical ones:

1. Webster drilling’s solids control system, which was fabricated by GN Solids Control years ago.

2. A helicopter lifting system with accurately calculated weights for each tank unit.

3. A 400BBL system with 2 mud tanks and 1 mixing hopper skid with limited height and minimum storage capacity.

And in HDD industry, GN Solids Control has delivered more than 30 sets of complete mud systems to Australia and GN Solids Control is the most famous Chinese brands, and one of the best known among international brands.
Shaker screen is another popular product GN provides to Australian market. Last year when GN upgraded the screen producing line and started to make all frame screens with composite material frames.

GN Solids Control is a famous brand who started from solids control equipment manufacturing, and now also professional in separation solution provider in nearly all fields including the oil gas drilling projects, HDD projects, TBM works, piling, water well drilling, drilling cuttings treatment, drilling fluids treatment and other industrial separation works.

GN EQUIPMENT WORKING VIDEOS
But still, among all the applications GN Solids Control’s products are used for, the traditional solids control system and equipment still occupies a large ratio among all GN’s products of each year, especially for the high standard clients, GN Solids Control is still their favorite and reliable supplier. For example, the Asian and Parcific market, like in Australia, New Zealand and India, where their standards are even higher than the USA and Europe.
In Australia, there are some special and difficult to reach standards, including the electric cable connections and layout, the tank surface treatment, the material choosing and even stair positioning. But GN Solids Control has rich experiences in working with Australia and New Zealand and also is well known by those clients. That’s why, during the past years, GN Solids Control has sold to Australia more than 30 sets of mud systems, not including the single equipment like decanter centrifuges and vertical cuttings dryers.

GN RECENT PROJECT NEWS
India is also a special market, India has talent management team and also brilliant engineers, they set up a high standard for their equipment, especially in oil and gas industries. For example, the shale shaker material, they always request the stainless steel as the material of the shaker frame. Although there are local solids control manufacturers in local India, still, clients are coming to GN for the suitable models and solutions. Even in Middle East, the management from big Middle East countries who are Indians prefer to choose GN Solids Control as manufacturer.

GN bIg bowl centrifuge

BIG BOWL CENTRIFUGE

Ever since the establishment of GN Solids Control seven years ago, Australia has been the market of GN Solids Control and most of their purchases have been mostly the solids control systems and mud recycling systems for the HDD or other drillings.

GN Recent News FYI: 

But now as the demand for environment protection all over the world is becoming more and more important, more and more drilling companies have paid an eye to the waste management solutions for further treating the drilling cuttings and the drilling liquid, in order to give the least damage to environment meanwhile reduce the drilling cost mostly, by deleting as much solids and well discharging them, and recycling as much as drilling liquid for future use.

Not long ago, an Australian company purchased 2 sets of GN Big bowl centrifuges, GNLW553-VFD, and now the centrifuges are well tested and ready for delivery.

What are the main specification of GNLW553-VFD Decanter Centrifuge?

1. bowl diameter of GNLW553-VFD decanter centrifuge is 22 inch, big bowl. By having this bowl diameter the max capacity designed for this centrifuge is 90 cbm/hour, equal to 400GPM.
2. a long ratio of length and diameter. This value is 3, so the length of the bowl is 71 inch. 3 is a perfect and practical length-diameter ratio, it gives an idea drying level of the solids discharge.
3. high speed up to 3000 RPM designed speed and typical speed up to 2500 RPM.
4. VFD control panal, GN uses positive pressurized control panel which could be used for high temperature condition and much safer than flame proof.
Besides above, the material and parts like bearings are of top brands and best quality, in order to ensure a reliable performance and a long service life.

In field of decanter centrifuge for oil and gas drilling, GN is always the leading brand.
