Economic configuration decanter centrifuge is the final phase equipment for the drilling solid control system. Keeping the equipment up and running all the time without any downtime will go a long way in determining the overall operational performance of the drilling project.
While it is important to make sure the equipment is kept in good condition and well maintained, making sure that it is being operated in right manner is equally important. A qualified and well trained operator will know the intricacies of operating the equipment and even know to spot the signs to raise the alarm.
Decanter centrifuge is high cost equipment. It is imperative that it is maintained well, after all the economy of overall project will largely depend on such wise measures only.
Here we are outlining a few tips with respect to operation and maintenance of decanter centrifuges :
1. Preparing for start-up: Before starting the centrifuge check all electric control system and related components. Test the rotating belt manually for any glitch. Inspect the overall panel for any alarming signs.
2. Start the equipment: Most of the modern horizontal decanter centrifuge comes with touch panel now that have fairly user friendly command buttons. Using the touch panel, release relevant commands to bring the equipment to start.
3. Preventive procedure: Once you are done setting up the system, do not directly start feeding the system, let it run for 5 minutes, add water to clean the stuck or dried material.
4. Shutting down the equipment: Do not cut off the power all at once and bring the machine to a halt. Gradually slow down the feed and let the machine process the remaining material till it lasts. Repeat the washing and cleaning procedure.
Make sure that no manual handling is done while machine is operational as it may be very risky.
Drilling Decanter Centrifuge is a device used in separating suspension of solids for drilling purpose. It has been designed for Oilfields and Industrial purposes that are seeking an environment friendly solution. Its speed ranges from 0n to 3900 RPM, generating centrifugal forces reach up to 3000G.
The main advantages of Drilling Decanter Centrifuge are;
1- It has a continuous dewatering in an enclosed unit, which reduces factory nuisances and cost of deodorizing premises.
2- The machines are cleaned automatically.
3- All mechanical safety mechanisms constitute part of the standard main equipment.
4- It is highly suitable for all sludge types, even the most difficult ones.
5- It is highly automatic and self-dependent machine with easy maintenance.
6- It has a very wide application range. The decanter centrifuge can conduct an effective separation as good as filtering centrifuge and can finish the separation despite failed filtering centrifuge.
7-Drilling Decanter Centrifuge can also be used for liquid clarification. It helps separation of lighter solids from heavier liquids.
8-It is usable in both high and low temperatures.
9- It has a Great Adaptability. It is capable of producing force even greater than the gravity, precisely 14,000 times greater than the gravity.
10- It grades the particles based on the size.
The disadvantages of drilling decanter centrifuges are;
1- It is an expensive and time-consuming process.
2- It has a complex structure, which is not easy to operate by a nonprofessional.
3- Sediment washing has not been very effective through this device.
4- Foaming of liquids may occur occasionally.
5- It is mechanically complex and tedious process.
6- The downtime for cleaning lowers the efficiency of Decanters.
7-Sometimes, the solids can build up inside the Decanters and cause a lower efficiency.
8- The Prescreening may be necessary to weed out particles too large to fit through the nozzles.

Drilling decanter centrifuge is equipment used to separate solids and fluid from a mixture using centrifugal force. Centrifugal force is a force, arising from the body’s inertia.
Drilling Decanter centrifuge technique replaces the conventional method of settling down the solids in the process of water treatment and likes. The technique makes the process faster and improves the quality of the output at the same time.
The drilling waste largely consists of drill cuttings and drilling fluids that are commonly called as drilling mud. Drilling cuttings are nothing but the rock shavings acquired during the borehole drilling process and the drilling mud is a mixture of chemicals that aids the drilling process by keeping the drilling bit cool and lubricated during the process of drilling.
Other than petrochemical industry the Decanter centrifuge has its application in number of other industries as well, e.g. food processing, waste water treatment, fish processing, chemical, mineral processing, organic chemicals, polymer and inorganic chemical industry to name a few.
Due to its wide popularity across different industries, a decanter centrifuge is available in various types and variety of designs. A few notable ones being – vertical orientation, horizontal orientation and conveyer or scroll type. Operators will be using their discretion to choose the appropriate type and design as per the application need, as that remains customizable.
The performance of same design and type of decanter centrifuge may also differ in two industries, as the performance will largely depend upon number of external factors, chief among them will be the type of the waste material they will be treating with. As the guiding principle of a centrifuge is the separation of fluid by buoyancy of the material it works on to separate.
Decanter Centrifuges are used in separating suspension of solids phase with particle ≥2μm in diameter for drilling mud and fluids handling.
All machineries will have its own set of requirements to give its user the desired performance and durability and off course the much desired economy. After all “Return on investment” is the mantra that investors care to heed about.
When it comes to solid control equipments, this is no exception. A few careful measures go a long way to ensure that the operators will find the equipment reciprocating their care for them.
The first and foremost one in this aspect is the preventive maintenance of the equipment. The decanter centrifuge as such is low maintenance equipment and has a high capacity of handling the drilling waste treatment , but that should not mean for the operators to simply overlook the state of operation of the equipment.
A very common mistake committed by the operators is the continuous use of equipment without giving it rest and inspection for any wear. The moment any component is spotted showing any signs of wear, operators should consider fixing it, without just pushing it for further use, however small. As it goes with machinery, that all components work in sync, so even a worn out rubber could cause the breakdown of entire equipment. So watch out for any kind of wear or damage.
Another challenge faced by drilling industry in context of economic configuration decanter centrifugeis the lack of trained personnel or operators. With evolving technologies, decanter centrifuges have been made much more automated and need little operational attention. However, to maneuver the equipment to achieve the desired output, need of staffing appropriate personnel is of paramount importance. With ever stringent health and safety regulations, rig operators struggle with their staffing needs.
The high turnover further adds to the problem. Finding the qualified and experienced operators and investing time in resources in training them to bring the up to speed is a very big challenge for project managers.
