Where there is a drilling, there are drilling cuttings. And all drilling cuttings need to be well treated, which means the oil or any other additional drilling agents should be removed as much as possible and the polluted soil, need to be discharged safely, if not safe enough to be returned to where it is from.
In many countries in the world, the drilling cuttings waste management system is a compulsory procedure in an oil and gas drilling project, alongside the drilling rig.

A drilling rig solids control system normally contains several steps for separation: shale shaker, desander cones, desilter cones and one or two decanter centrifuges. Among those, the shale shakers take the heaviest separating duty, for choosing out all solids particles bigger than 100 microns. While the desander and desilter, by using their 10 inch and 4 inch cones, are used to choose out particles of 70 and 20 microns. Barite in the drilling fluid is recovered by a middle speed decanter centrifuge, while fine particles are to be handled by a high speed decanter centrifuge.
In practice, most of discharges are from the shale shakers and those discharges are quite wet, too wet to be disposed or even transported. A vertical cuttings dryer is mainly used for treating the disposals from the shale shakers. GNCD930E-GP vertical cuttings dryer is quite efficient in this work, it could reduce the OOC to be less than 0.5%. After the vertical cuttings dryer, there should be a high speed decanter centrifuge to treat the discharged liquid phase from the vertical cuttings dryer, for separating out the fine particles which are left. Here, a GNLW363CG-VFD centrifuge is quite an ideal option.
Recently, GN Solids Control just finished the manufacture for several sets of such drilling cuttings separation units, now they are ready to be delivered to Russia.

Just recently, GN Solids Control just finished building of a 3rd Lab Oily Sludge Treatment Unit, one of the many sets of different models GN has provided to different clients in different countries. And this set of OST is customized for a domestic client, in their customized color, with their customized equipment list.

GN has several different optional models for the oily sludge treatment solutions. Being divided by equipment, GN has some specific equipment for each application, for example, the shale shaker is always the first step for separation, which is used to move out the most solids by using the correct meshes. Centrifuge is an essential part of the complete system, which is used to separate out the fine particles from 2 micron to 5 micron. Between the shale shaker and the centrifuge, if there are extra fine particles even smaller than 2 to 5 microns, then there should be a chemical dosing unit to help with feeding the centrifuge, for flocculating the extra fine particles to be separated by centrifuge. An inclined plate clarifier is also efficient for reducing the particle content entering the centrifuge, enhance to raise the efficiency of centrifuge. After the centrifuge, there is an oil water separator to final separate the oil and water.
Another option equipment allocation is almost same in procedure but different in choosing equipment. In this new design, before the shaker, there is a pre-heating unit for helping to reduce the viscosity of oily sludge. And a chemical dosing unit could add chemical into pipelines both before and after shaker (before centrifuge) per sludge conditions. The oil water separation procedure is simplified by a disc stac.
In both solutions, the oil is to be recycled, the water is to be reused into unit while the solids could be safer and easier treated.

Silently, the year 2018 slide by with gains and pains. As we opened the calendar of year 2019, the CIPPE Oil Show come as scheduled by end of March, in Beijing International Exhibition Center, capital of China.
In the past several years, the oil and gas industry suffered a roller coaster time as the crude oil price went up and down. It was both challenge and opportunity for a promising company, like GN Solids Control, which has developed from a new solids control brand to a leading manufacturer in this market. CIPPE Oil Show is a good platform for all brands both in domestic China and abroad, and this oil show also witnessed GN’s achievements in past years. Each year, GN Solids Control would bring to CIPPE some new designs.
In year 2017, GN Company set up its second factory in the same industry zone as headquarter, and moved its shaker screen factory and centrifuge workshop to the new factroy. In CIPPE, GN Solids Control got a full range of decanter centrifuges to CIPPE, including a baby centrifuge with 9 inch diameter bowl and a big bowl centrifuge with a 30 inch diameter bowl. In fact, GN Solids Control now has a full range of decanter centrifuge products including the bowl diameters of 14 inch, 18 inch, 22 inch and even 30 inch. For the popular sizes, like the 14 inch series. 18 inch series and 22 inch series, there are both 3 and 4 L/D ratio models available.
In year 2018, GN put into market 3 models of vacuum pumps, with capacity from 10 cbm/hr to 40 cbm/hr, which is an efficient choice for transferring drilling waste, oily sludge, and even animal waste. Meanwhile, GN’s several different solutions for oily sludge were proved to be successful. In same year’s exhibition, GN’s lab OST had attracted lots of professional visitors’ eyes, and fully met clients’ requests in this field.
For CIPPE 2019, what surprise will GN bring to us?
Let’s see at GN Booth E2168 on March 27th.

Horizontal Screw Centrifuge, is shortly mentioned as decanter centrifuge, is widely used for many different industries for separation. GN Solids Control has been manufacturing decanter centrifuges for years, at first, those horizontal screw centrifuges made by GN Solids Control were designed for oil and gas solids control projects, then, to be used in waste management projects for both drilling cuttings and drilling fluids. In recent three years, such centrifuges are also used for oily sludge separation works.


Clients from different industries who trusted GN Solids Control are using GNLW decanter centrifuges in different projects, and GN Solids Control is also exploring more applications for GN centrifuges. Meanwhile, GN is designing different models for decanter centrifuges, not only different sizes, but also different slope angles… to meet more applications.
Recently, a client has tested his material with a GNLW Decanter centrifuge and the feedback is more than satisfactory. This customer’s work is to treat aluminum hydroxide slurry. His aluminum hydroxide slurry has a concentration from 8% to 10%, and their aim is to remove water from the aluminum hydroxide mixture and enhance the concentration up to a high level from 60% to 80%. In the raw material, there are alumina in fine particles and also dissolved sodium nitrate in water. After strict test with real material, GNLW series centrifuge could fully meet the desired separation standards.
Based on requested treating capacities, GN has various centrifuge models from 9 inch diameter centrifuge bowl to 30 inch diameter bowl, designed at high speed or mostly variable frequency. If you or clients have similar projects which are in need of such centrifuges, please contact GN directly, GN professional engineers would help with choosing a suitable centrifuge model.
