3 Phase Decanter Centrifuge Operation Principle:

Similar with 2 phase decanter centrifuge operation principle, under the centrifugal force the feeding material can be divided into three relative stable layers. From the bowl inside wall there will be solids phase layer, heavy liquid phase and light liquid phase.

The solids phase layer is pushed to bowl small-end part by conveyor and discharged from solid outlet. The heavy liquid phase and light liquid phase are delivered to bowl big-end part and discharged separately from two different outlets.

It can reach three-phase separation.

Separation Type:

Solid -liquid –liquid

Liquid -liquid-solid

What’s the Solid Control System consist of?

Kosun as the professional solid control system manufacturer, we have our own understanding about this system.In Kosun’s words, solid control system is also called drilling fluids purification system, primarily applied for solids control and solid-fluid separation in drilling fluids so that the drilling mud might be recycled. Consisted of 3-7 module composite tanks and configured with 4 phases of purification equipment, it is fit for 2000-7000 meter oil drilling processes. The whole system is innovative with the bottoms of its purification tanks made to be conical and its edges equipped with mud agitating system to prevent solids from depositing. Besides, its tanks and bins may be comparted or united depending on the demands of drilling processes. Each of them is connected to another via pipe network in which the valves at the bottom of suction pipes are flexible while being opened, but can turn to be a good seal when closed.

What’s the  Solid Control System consist of?

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.

Cutting Dryer very Popular all over the World

Cutting Dryer

Vertical cuttings dryer use the centrifugal force to separate the oil from the drilling cuttings generated during oil extraction process from an oil well. The drilling cuttings are the waste product generated in large volume in drilling operations.
They are gaining popularity worldwide due to their capacity to separate oil from the solid waste that could be measured as ROC (retained oil on cuttings) or OOC (oil on cuttings). They are said to recover as much as 15% of the volume of the total waste. This not only saves the environmental damage but results into unintended loss of oil and economy of operations.

The way a vertical cutting dryer works could be understood in these simple steps –
A.    The drilling waste is churned using centrifugal force generated by mechanical rotation that results into separating of oil from solid.
B.    The drilling cutting generated solid waste is eliminated using sieve basket and scrapper.
C.    The liquid thus extracted is carried through pipes to a separate tank for further treatment and solid remains in the basket
D.    Then the dried solid waste is discharge to a separate container for further disposal.
The drill cuttings thus separated by cutting dryer from drilling liquid forms large part of the drilling waste and needs to be disposed off safely to prevent the contamination of environment.
Drilling waste treatment was not given much importance in earlier period when drilling operations came into existence but the scenario changed rapidly off late beginning early 1980s in wake of damaging impact of un-thoughtful disposal methods used by companies. The oil and gas industry has become more aware of their responsibility toward the environmental wellbeing thanks to number of protests by local people where such damages were evident and intervened by regulatory authorities thereafter.
Since then the technological advancement has played significant role in improving the drilling operations and their environmental footprints. Vertical Cutting Dryers are one such significant development in that direction.

Vertical Cuttings Dryer Your Best Choice

Vertical Cuttings Dryer

Vertical cuttings dryer is used to separate the drilling liquid and mud, and which can save a lot for the spending drilling companies.

Below are vertical cutting dryer from Kosun:

The main application area is about offshore and onshore projects, where the recovery of valuable drilling fluid from cuttings, as well as recovery of whole mud lost from shale shaker failure, rig motion and shaker screen blinding are priorities.

Vertical cutting dryer has the following advantages during operation:

1, Programmable Logic Controller (PLC), with automatic warning indicators, monitors temperature, torque, oil flow and operating hours;
2, High-capacity, continuous feed units have the throughput to keep up with drilling;
3, Tungsten-carbide-coated, independently adjustable flights reduce wear and ensure optimal tolerance;
4, Handrail and walkways is convenient for operators to do routine maintenance work, that can reduce risk to personnel;
5, Different kinds of screens can meet various operation requirements.

As we know, no sketches, no understanding, so here we are the sketch pic of vertical cuttings dryer:

And from the respect of environmental protection and cost, vertical cuttings dryer from Kosun also popular for:
a, Highly effective liquids/solids separation minimizes fluid content of cuttings;
b, Reduces drilling  waste-disposal volumes;
c, Effective separation reclaims high percentages of fluid that can be reused in the active mud system;
d, Recovers whole mud lost from shale shaker failure, rig motion and screen blinding, that is cost- effective.

The after sale maintain cost are always the problem by all the customers, and vertcial cutting dryer from Kosun also take much attention on this point:
1. Normal wear parts are easily accessible from the top of the unit; belts are easily
2. changed without removing gear assembly
3. Interchangeable tungsten carbide flights protect rotor and gear box from excessive erosion, minimizing main component failure
4. Explosion-proof motors and control panels can be certified with CE/ATEX
