Decanter Centrifuge Application in Oil & Gas Industry


Application
Decanter centrifuge is used in separating suspension of solid phase with 2～70% solid concentration, liquid viscosity ≤0.01PaS, particle diameter d≥2μm, in clarifying suspensions with little solids as well as amorphous material that brings difficulties for filtering cloth regeneration and suspensions which have a big change range in solid phase concentration.

The decanter centrifuge is also used in the solid-liquid separation in the fields of oil & gas industry, chemical industry, food, pharmacy and environmental protection, carrying out dehydration of solid phase, liquid clarifying, liquid-liquid-solid separating, granularity grading and other separating processes.

Structure
DC series horizontal 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.
 
Feature
Decanter centrifuge is a professional solid-liquid separation equipment designed according to the petroleum drilling fluid features. And the equipment can perform feeding, centrifugal settlement and unloading as well as other solid-liquid separation operation procedures, used in recovery barite, removing fine solids, lowering solid content in the drilling fluid, controlling the drilling liquid viscosity and density to guarantee the drilling liquid performance and has a significant effect on fast drilling.
v easy adjustment for liquid pit;
v fluent slag transporting and draining;
v convenient washing and maintenance.

Mono Screw Pump Working Principle and Apllication

M ono screw pump , also called  sewage pump  or  progressive cavity pump ,  belongs to the rotor type positive displacement pump .   M ono screw pump  is depend ing  on the screw meshing with liner on the discharge and suction cavity to conveying liquid volume change.   It is a kind of method of pressurized screw pump, a main working parts by bushing has a double helix cavity (stator) and the stator cavity and its meshing singlehead screw screw (rotor).   When the input shaft through the universal joint drive making planets revolving around the center of the stator, rotor stator, rotor, vice is continuous mesh form sealed cavity, the seal chamber volume invariably uniform axial movement, the medium from the suction end of deputy to the stator, rotor pressure side, the suction medium sealed cavity through the stator without stirring and destruction. M ono screw pump  is an ideal pump used to feed drilling fluids to ...

Drilling Waste Disposal-Pit Burial

The use of earthen or lined pits is integral to drilling waste management. During most China  drilling operations, the drilling cuttings separated by the shale shaker are sent to a pit called the reserve pit located near the drill rig. The pit is generally open to the atmosphere, so it also accumulates stormwater and washwater from the rig. The strategic location of small pits near drilling sites can also help minimize spillage of drilling waste. Unless site characteristics are such that no significant threat to water resources can occur, liners are generally required. Where pits must be constructed adjacent to water bodies or on sloping terrain, engineering precautions incorporated into the design will help to ensure pit integrity. Precautions should be taken to prevent disposal of chemicals, refuse, debris, or other materials not intended for pit disposal. At the end of the drilling job, any hydrocarbon products floating on top of the pits are recovered and any free...

Drilling Waste Separation by Solidification and Stabilization

Drilling waste separation  from the mud at the shale shakers may be coated with so much mud that they are unsuitable for the drilling mud recycle or disposal step or are difficult to handle or transport. Constituents of the drilling cuttings or the mud coating them, like oil or metals, may leach from the drilling waste, making them unsuitable for land application or burial requirements. Kinds of materials can be added to drilling cuttings to solidify and stabilize them. Solidification is a technology that encapsulate the drilling waste in a monolithic solid of high structural integrity. The encapsulation may be of fine drilling waste particles or of a large block or container of drilling cuttings. Solidification does not necessarily involve a chemical interaction between the drilling waste separation and the solidifying reagents but may mechanically bind the drilling waste into the monolith. Contaminant migration is restrict...
