Some clients cannot tell difference of fixed speed centrifuge and fix speed centrifuge, they wonder while price for each so difference.

Centrifuge itself for the 2 types is the same. The different lies in electric control panel.For a fixed speed centrifuge, usually, a smaller control panel mounted on the pedestal of centrifuge, to control its on and off, and for emergency stop.In some condition, clients, want better explosion proof and do not want hydraulic drive, they will require a bigger box for fixed speed.

Variable speed centrifuge mainly used for liquid-mud plant and waste management. it uses a big VFD control panel. The control is too big to set on the same skid with centrifuge.Beside control on and off, if also offer control speed of main dirve, back drive, and sometime, feeding pump.

No rig can drill without generating waste. The types of waste generated include drill cuttings, waste water, spent drilling fluids, completion fluids and filtration wastes. Mostly, drilling waste from well head recovered while through solids control system and waste management system. Recovered fluids returned to well head for drilling. Dryed cuttings moved away by trucks for construction or paving.

But while the well finished or rig stop, drilling fluids from well head cannot discharge directly to environment. Drilling cuttings can be treated by solids control and waste management system:shale shaker, desander, desilter, centrifuge,high G., vertical cutting dryer,etc…

Great amount or fluid-phase waste generated, which is formerly recycling to wellhead for drilling. In this case, liquid-mud plant need be used.

A common type of liquid-mud plant is actually a series of VFD decanting centrifuge and feeding pump. Before go into decanting centrifuge, the useful drilling fluid go through flocculation system for treatment. Fine solids can be polymerized into larger size for an easy separation.
