Decanter centrifuge is the most important equipment for drilling waste management field. It can be used for waste water treatment, slurry separation, oily sludge separation, etc…

Application of decanter centrifuge for waste management field

1) Decanter centrifuge can be used together with high G shale shaker to treat water base mud drilling cuttings. Water base drilling cuttings is treated by high G shale shaker, after shaker, goes to decanter centrifuge to separate the fine solids.

2) Decanter centrifuge can be used together with vertical cuttings dryer to treat oil base mud and synthetic based mud drilling cuttings.

Oil base mud and synthetic based mud drilling cuttings from tank bottom, shale shaker, desander desilter or offshore rig, are treated by vertical cuttings dryer first, after vertical cuttings dryer, goes to decanter centrifuge to separate the fine solids.

There are so many companies declared for decanter centrifuge manufacturing, but do you know how to choose the right decanter centrifuge and optimize the centrifuge performance?

Firstly, the reliable brand should be chose depends on the applications. For centrifuge brand section, you should check with the supplier, if their centrifuge have been used for the similar applications and the performance, or at least their reference on waste management field.

If their centrifuge mainly used for solids control mud system, most probably, it will not suits for waste management. As for waste management, the material is more critical, high solids content and high abrasion. If request the centrifuge should be very reliable on design (feeding port, solids discharge port, screw protection, control panel, etc…) and excellent on material choose.

Secondly, choose a suitable model per your application: high speed / high G force / big bowl / super high speed… There are so many design. You should choose the most suitable model per your material condition and the performance you want to get.

For example, if you want a normal system to do service, you want the system can treat more kinds of drilling cuttings, OBM, SBM, WBM, GNLW363CG-VFD decanter centrifuge should be suitable. It is a 14 in centrifuge with adjustable speed for different application.

Then, even for the same centrifuge model, the different fluids level height, bowl speed, conveyor speed, feeding capacity, jobsite layout, feeding type will affect the performance greatly. That is the reason why centrifuge request a professional operator together. Decanter centrifuge has high request on operators’ capability than solids control system. Many jobsite, they have good machine, but do not equipped with professional operator, so also problems.
