3 Phase Decanter Centrifuge in Oil Recovery Unit

3 Phase Decanter Centrifuge(Three-phase Decanter Centrifuge) is also called Tri-canter centrifuge, it is commonly used in oil drilling work to separate the oil rate from drilling solids, it belongs decanter centrifuge series. In Oil Recovery Unit project, 3 Phase Decanter Centrifuge is the core solid control equipment in the whole system. Today we will share more information about 3 Phase Decanter Centrifuge.

3 Phase Decanter Centrifuge

Just as we all know that decanter centrifuge is the main equipment for a whole solid control system, even in the drilling waste management unit, we also need a VFD decanter centrifuge (of course, cutting dryer is also the core part one on drilling waste management, while mud cleaner is the important equipment in solid control system), both system should be worked with drilling mud tank, that is to say, the whole equipment should be mounted in the mud tank. 3 Phase Decanter Centrifuge is the core one for the whole oil recovery unit.

You will find necessary information about oil recovery unit in last post. We did not mention the 3 Phase Decanter Centrifuge in that post. In our design, 3 Phase Decanter Centrifuge is a kind of solid control equipment used to separate the mud, water and oil from the drilling solids. Comparing with traditional decanter centrifuge, the most important function of the three-phase decanter centrifuge is that it could separate the oil from the drilling solids, while the traditional one just could separate the mud and water.

Generally speaking, 3 Phase Decanter Centrifuge is always used in huge solid control system or the system like Oil Recovery Unit. The common feature of these units is they are huge and complicated. At the same time, because of the high technology needs and heavy difficult for design and manufacture, 3 Phase Decanter Centrifuge is the one with blooming and splendid.

Why decanter centrifuge is indispensable in drilling operation?

Before hydrocyclones (desanders and desilters) and decanter centrifuge became available for drilling applications, shale shakers and dilution were the only means of solids control of drilling fluids. Consequently, solids too fine to be separated by the shaker screens in use could be controlled only by dilution which was a costly procedure that generated large quantities of excess drilling fluid. Decanter centrifuge was designed to remove the fine cut and at the same time reduce the drilling cost.

The work principle of decanter centrifuge:Centrifuges, like shale shakers and hydrocyclones, are solids control equipment, It achieves the separation goal by dividing the fluid into highdensity and lowdensity streams to separate one from the other. The processing is achieved by accelerated sedimentation. As the drilling fluid passing through a rapidly rotating bowl, centrifugal force moves the heavier particles to the bowl wall, where they are scraped toward the underflow discharge ports by a concentric auger, also called a scroll or conveyor, which rotates at a slightly slower rate than the bowl. The separation of the heavier particles divides the processed fluid into two streams: the heavy phase, also called the underflow or cake; and the lighter phase, which is called the overflow, light slurry or centrate. The heavy phase will be discarded while the lighter one will be returned to the mud tank to be further treated. The removal of these solids in order to control rheology and filter cake quality is the primary reason for centrifuging weighted drilling fluids. When the finest solids are not removed, the only alternative means of reducing their concentration is dilution, always an expensive process.

Features of KOSUN LW serious decanter centrifuge

Brief description of Decanter Centrifuge

A decanter centrifuge is a device that can create a very fast rotation. A decanter centrifuge is basically used to dilute the fluid that is extracted from the gas or oil mine. Generally, the liquid that is extracted from a mine is of highly concentrated and coagulated. So, extracting minerals from them is practically impossible.  In order to thin up the extracted fluids. By using the rotational speed of a decanter centrifuge, the highly concentrated are turned into minerals extractable thin liquid. There are three basic designs of decanter centrifuges.

Decanter Centrifuge
Decanter Centrifuge

The first one is vertically oriented decanter centrifuge, the second one is horizontally oriented decanter centrifuge and finally the third one is conveyor or scroll decanter centrifuge. In the vertically oriented decanter centrifuges, the fluids or solids are gathered vertically. Vertical decanter centrifuge isvery effective for high temperature and high pressure work. A horizontally oriented decanter centrifuge gathers the fluids or solids generated from high rotation in horizontal orientation. A horizontally oriented decanter is very effective for high pressure works as it provides a strong organization due to its horizontal orientation. Lastly, a conveyor or scroll centrifuge is basically a rotating machine inside a bowl.

How does a decanter centrifuge work?

As it is mentioned before the process of a decanter centrifuge is a bit complex. Usually, a decanter centrifuge depends on sedimentation, differential speed and G force to perform its job. The sedimentation rate is an important feature for the centrifugal process. If the G force or centrifugal force is very high, the separation process becomes very easy and effective. The size and shape of particles and their level of concentration determine the sedimentation rate of any decanter centrifuge. The sedimentation rate also depends on the centrifugal force.

Another important issue for the functionality of a decanter centrifuge is the differential speeds. In a centrifuge two different parts rotate simultaneously. The first part that rotates is the exterior bowl and the second part that rotates is scroll conveyor. Sedimentation is gathered in the centrifugal cylinder as the result of varying speed of the two above mentioned separate parts. If the differential speed of a decanter centrifuge is too high, a little time is required to loosen up the concentration of waste fluids. So, it is very important to keep the differential speed of a decanter centrifuge minimal. Thus, a decanter centrifuge operates its functionalities. (Editor:Kosun Lily.Wang)

Features of KOSUN Decanter Centrifuge for sale

Solids control equipment decanter centrifuge is one stage of solids control system.Normally solid control system is consist of five stages, including mud tank, shale shaker, vacuum degasser, desander, desilter, decanter centrifuge. Shale shaker is used to separate the big solids with diameter above 75μm, and 45~74μm for desander, and 15~44μm for desilter. Sometimes desander & desilter are combined as Hi-volume mud cleaner. When air enters into the drilling fluids, vacuum degasser is used to separate the air. If no air in the mud, the degasser would work as a big agitator. All these equipments are mounted on the top of the mud tank. Decanter centrifuge is used in separating suspension of solid phase with particle diameter d>=2um for drilling mud and fluids handing. After separating the solids, the mud would be pumped into the borehole again.

Solids Control Equipment Decanter Centrifuge Common Troubleshooting

Solids control equipment in one of the indispensable mud sand pump equipment used in the process,Desander Hydrocyclone will encounter some of the problems of how we want to troubleshoot it?( Decanter Centrifuge Troubleshooting)

If worn, then Desander Hydrocyclone may be the following two questions:

The first packing (packing) seal leakage serious, packing heavy wear, surface wear sleeve.

Remedy: Remove the packing (packing), with a 90 ° bend thin wire inserted into the cartridge mechanical seals, Oilfield Drilling Mud Decanter Centrifuge is bushings moving wall, if the check of Oilfield Drilling Mud Decanter Centrifuge is to be too deep for-sleeve trench filler cap too tight will lead to severe wear fillers.

Second, DWM Solids Control of polyurethane seals wear serious cause leakage.

Remedy: Replace polyurethane seal (Normally, when the sand pump is running 3-6 months, Drilling Mud Cleaner should be replaced at once polyurethane seals and seal sleeve).

There must be an electrical engineer specializing in operation and maintenance. At present, only a few well-drilling operations abroad with the type of high-speed centrifuge, high performance requirements for drilling special wells, Drilling Mud Cleaner recommended speed centrifuges and centrifuge series of domestic high-speed process, the medium-speed centrifuge drilling into the post-processing of high-speed centrifuge for liquid storage, treatment by high-speed centrifuges, Drilling Fluids Desander used repeatedly into the circulatory system. Drilling Fluids Desander at this time to get a better purification of positive significance to improve the follow-up equipment of DWM Solids Control (drilling sand pump, drilling, downhole equipment, etc.) of the life-saving mud material consumption, improve ROP and other aspects in Dwm control.

Introduction of the Main Equipment for Solid Control System

Recent years, with the requirement of high working efficiency in drilling industry, a new system has been designed and developed in some big solid control manufacturer, and the system is called “solid control system”. Kosun as the leading original manufacturer of solid control equipment and drilling waste management unit, the “solid control system” is not a problem for us.How to understand solid control system? As the professional solid control system manufacturer, we have our own understanding about this system.

Introduction of the Main Equipment for Solid Control System:

The first main equipment for solid control system should be the vacuum degasser,We could analytics from the function of vacuum degasser. Generally speaking, horizontal vacuum degasser will be used to separate the gas from the drilling solids. What’s the reason to do like that? Because we should do everything to prevent any dangerous elements in oil & gas drilling fields. That’s why we should put the vacuum degasser as the first role.

The second one should be mud cleaner. KOSUN MD Series Mud Cleaner is the second stage separation equipment for drilling fluids, which deals with the mud being treated by the first grade separation equipment. The barite will be recovered and cuttings which are bigger than barite will be removed. Then the barite in the underflow will flow into circulation tanks through the screens when the weighted mud passes while the particles that are bigger than mesh will be removed.

The third equipment, we think it should be shale shaker (with necessary steel frame shaker screen). Actually, after the drilling solids have been transported and fed into vacuum degasser and mud cleaner, the third step is going with shale shaker. Commonly, we still need to be transported the solids onto the shale shaker, or we could say onto the surface of shaker screen. The equipment of transporting we should use is centrifugal sand pump or screw pump; and we may use shear pump to cut the drilling solids into small one if they are in big size. With the different design of the shaker screen’s mesh, we could get the drilling solids separated in different sizes.

The fourth equipment should be the decanter centrifuge. KOSUN DC Series Decanter Centrifuge is used to separate suspended solids ≥2μm in diameter and treat the drilling mud and fluids. It is especially effective when used in oilfield service industry, industrial service industry and especially in environmentally sensitive areas. This type of centrifuge is high in recovery rate, effective in solids control and remarkable in the reduction of cost spent on drilling mud resupplying and management. It is a very sophisticated dynamic balancing machine, able to operate stably with the whirling speed ranging from 0 to 3900 and generate centrifugal force of 3000G. In solid control system, decanter centrifuge has been popularly used, which is also the popular one for drilling waste management. In this step, we could not only get the result of separating, but also we could separate the oil from the drilling solids, even if the oil is just a little part.

Of course, the whole equipment must be mounted on the top of drilling mud tank, which is a kind of basic equipment for both solid control system and drilling waste management (vertical cutting dryer is the core equipment for this system), but it is a kind of powerful equipment.

KOSUN was founded in Xi’an China in 1992. Up to now, KOSUN has formed a strategic layout integrating three centers and two industries. The Production, R&D and Domestic Sales Center is located in Xi’an China, the Overseas Project Management Center and International Trade Center in Beijing China and the Oilfield Services and Oilfield Engineering Center in Aktobe Kazakhstan in Central Asia. The two industries are traditional oil drilling solids control equipment manufacturing industry and integrated oil & gas drilling waste management service industry respectively.(Editor:Kosun Lily.Wang)
