The standard model of DC Oil Sludge Treatment Plant

⋅ Leave a Comment

Oil sludge is a mixture consisting of oil, water and solids. The treatment on oil sludge would recover much oil and water for reuse. Also it is an ideal solution to for the solids disposal. More oil and water recovered, more energy and resource could be saved. DC oil sludge treatment plant mainly include decanter centrifuge, oil water separators and thermal desorption unit.

What equipment available from DC for Oil Sludge Treatment?

Shale Shaker for coarse solids separation
Decanter Centrifuge for fine solids separation or water and oil separation.
Polymer dosing system for better oil sludge demulsification
Dewatering System for ultra fine solids flocculation
Oil Water separators for two phase liquid separation.
Thermal desorption unit for minimize the oil on the solids down to 0.3%.

Oily Sludge Treatment Process

The main technology we used to dispose of the oily sludge is pyrolysis. Let’s see the specific process of working,
1. Collect all of the oil sludge together and then unload them to the workshop. Most of our oily sludge pyrolysis plants are installed in the open air. And then use our auto screw feeder to feed them into the pyrolysis furnace.
2. Under an oxygen-free, high temperature and sealed environment, the three main components of oil sludge, oil, sludge, and water, will be decomposed.
3. When the temperature rises to a certain degree, oil gas will come out. Thereinto, heavy particles in the gas will be liquefied into heavy oil and then dropped into the heavy oil tank; light particles in the gas will rise up and liquefied into light oil in the horizontal tube condenser and then also be reserved in the oil tank.
4. The slag will be automatically collected during the process.
If you have interesting with the oil sludge treatment system, please contact DC office to get more info about it.

decanter centrifuge

DCLW Decanter centrifuge is driven by two motors. The main motor drives the drum and the outer casing of differential through belts while the auxiliary motor, after the differential shifting speed, drives the spiral propeller. This will make the drum and the spiral propeller rotate in the same direction with a certain differential speed.

decanters

Decanter centrifuge are used to process unweighted and weighted, water-based and oil-based drilling fluids (muds). Mechanical energy is utilized to increase the gravitational force exerted on solids that are present in the mud system.oilfield Decanting Centrifuge are able to apply over 3,000 G-forces on the liquid/solids mixture, which separates the heavier solids from the lighter solids. Additionally, high G-forces separate fine solids from liquid.

Today we shipped a set of DCLW350-1200 decanter centrifuge to pakistan used for wastewater treatment. The dewatering decanter centrifuge is designed for easy separation material include large particle size, high density difference of solid and liquid, low viscosity, high concentration, high treatment capacity and higher dryness than clarity. The materials like sludge or wastewater containing fine particles usually need to be added with flocculants to gather the fine particles condensed into large ones, and then dewatered with DCLW series decanter centrifuge.

The characteristics of Decanter centrifuge by DC

:1. Innovative design includes longer bowl, allowing drilling fluids to thread through more slowly, thus resulting in drier solids and finer separation point;
2. Big bowl offers big volume. It also generates high-G force;
3. Stainless steel bowl, scroll, compartment are available and covered with corrosion-proof coating so as to have longer lifespan;
4. Tungsten carbide scroll points with wide spacing flights at tapered end create a finer layer of conveyed solids for consistent, uniform separation and maximum solids control efficiency.
5. German FAG or Swedish SKF brand bearings are available;
6. Electrical Components complies with SIEMENS/Schneider ATEX or IEC Ex.

The Operation Principle of Drilling Mud Decanter Centrifuge

The drilling fluid decanting centrifuge is driven by two motors. The main motor drives the drum and differential shell rotation by the belt . The vice motor drives the spiral through the differential variable speed . The drum and spiral
rotate together in the same direction, but at different speeds . Separate the solid phases in the drilling mud by the centrifugal sedimentation principle. Suspending fluids is pushed into the rotor drum through the inlet pipe and under
the force of screw propeller, under the effect of centrifugal force, the solid phases will be pushed onto the inside wall of the drum, pass the impeller on the screw propeller and be discharged from the exhaust hole at the small side of
the drum. The fluids is excreted from the overflow hole of the large end. So continuous circle like above to achieve the target of continuous solid-liquid separation.

DCLW decanter centrifuge adopts centrifugal force to separate solid particles out of drilling fluid.Different solid or particle have different density and flow speed,some decanter centrifuge also can separate particles as different size
and density DCLW decanter centrifuge is widely used in oil and gas drilling,chemical,foodstuff,pharmacy,mineral beneficiation,water treatment,etc.
