Oil sludge treatment equipment

• Centrifugal Mud Cleaner:

The traditional desander, desilter or mud cleaner uses hydro cyclone as the core part of solid-liquid separation.

Their disadvantages are high energy consumption (the cyclone driven by a 55KW or 75 kW sand pump) and also unstable de-sanding effect (clogging, abrasion, pressure instability, etc. affect the separation), so the equipment efficiency is not high. Company designed a centrifugal desander to solve the above problems.

The centrifugal de-sander/Desilter working principle is a big diameter bowl low-speed centrifuge, but because of its specially designed drum structure, it is suitable for super high volume mud processing, and it can remove sand without reducing the mud weight when processing heavy mud. Both fixed speed and VFD speed are available.

Centrifugal desander/desilter/mud cleaner advantages:

1. Low energy consumption compared with traditional mud cleaner 
   2. Better treatment result that can separate even less than 45 microns cuttings
   3. Flexible speed and capacity adjustment, better control the mud weight 
   4. Less pipelines requirement and more effective volume for the mud tanks 
   5. Less maintenance and consumable spare parts

• Vacuum Degassers:

Degasser is special equipment used in solids control system to remove the gases such as hydrogen sulfide, carbon dioxide and natural gas from the drilling mud before they reach the shale shakers.

Mud gas separator or degasser is a vacuum unit, which is mainly composed of vacuum tank, vacuum pump, motor, vacuum pump system and electrical control box. Vertical and horizontal vacuum degasser for your option.

Vacuum degasser adopts three methods to separate gases from the drilling fluid:

1. The drilling fluid is thrown toward blade and tank wall in jetting form through the windows around the hollow shaft of rotor, the gases contained in the drilling fluid break and escape from drilling fluid.
2. Negative pressure is generated in the vacuum tank by vacuum pump, the bubbles in the drilling fluid expand to surfaces and break, and thus gases can be separated from mud much easier
3. The foam separator and two layers impeller continuous rotate which drive the gases appear and break.

Vacuum Degasser Specs:

The choice between horizontally- or vertically-mounted units is typically based on the footprint requirements of the specific rig.

Mud/gas separators and degassers are just a few of the many solids control and drilling waste management offerings that company supplies to the oil and gas industry.

• Shale Shaker:

Shale shaker plays an important role as first mechanism for solids removal. If it fails in normal operation, there will be trouble for the subsequent solid control equipments (cyclone and centrifugem etc.). Therefore, the choosing of drilling fluid shaker is very important.

• Mud Cleaner:

Mud cleaner is a combined unit of shale shaker, desander, desilter hydro cyclones and manifold. In drilling mud solids control system ,it is installed behind shale shaker as second and third grade solids control equipment, minimum separation point 15um. The fluids recovered can be pumped back to well use directly or for next phase separation by decanter centrifuge for ultra-fine solids removal.

Mini mud cleaner integrate smaller footprint drying shaker and desander, desilter hydro cyclones, offers better performance than traditional desander and desilter. It is an economical solution for barite recovery and separation of LGS. Most popular for small power drilling rig in oil & gas, CBM, HDD industry.

   Single screw pump is a kind of positive displacement pump, which can deliver media with different density and viscosity, the best feeding pump for decanter centrifuge. Rigid rotor rotates in the elastic stator (usually made of rubber) to deliver medium. In addition, rotor is a rod component with single-end external thread, while stator is a sleeve component with double-end internal thread, which forms a continuous sealing line in a threaded shape. At the time of working, the seal cavity, which is formed by threaded sealline, moves forward continuously to deliver media in the cavity.
