M-I SWACO mud cleaners are designed to work with either oil- or water-base weighted muds, as well as with either dispersed or non-dispersed muds. They are also effective on unweighted drilling-fluid systems, removing fine drilled solids while retaining expensive liquid phases. Field-proven, M-I SWACO mud cleaners are especially effective in controlling drilled solids and retaining expensive barite when used in conjunc -tion with M-I SWACO fine-screen shale shakers and centrifuges.
Features and Benefits

• Cuts downtime and reduces repair
• Complete product line provides diverse configuration options
• Field-proven performance
• Lowers drilling-fluid and disposal costs
• Minimizes maintenance on downstream equipment
• Compatible with oil- or water-base muds

The M-I SWACO 414 CENTRIFUGE* delivers high performance and low operating costs for oilfield and industrial mud and fluids-handling applications. This highly efficient decanting centrifuge recovers up to 95% of barite and returns it to the active system, while rejecting finer, low-gravity solids.
The advanced design of the stain-less steel bowl and scroll maintains an even layer of conveyed solids for more uniform separation and maximum solids-control efficiency.

518 C ENTRIFUGE
138
The M-I SWACO 518 CENTRIFUGE* is the premier high-speed, decanting centrifuge for drilling-mud and fluids-handling applications.
Ruggedly built for oilfield and industrial service, it is especially effective in environmentally sen -sitive areas. It delivers high fluid-recovery rates and efficient solids control to significantly reduce the costs of makeup fluids and disposal.
The M-I SWACO 518 CENTRIFUGE is precision-balanced for smooth operation over long periods at speeds of 1,900 to 3,250 RPM, generating centrifugal forces up to 2,100 G’s.
How it works
Features and Benefits
• Innovative design includes longer bowl for increased retention time, resulting in drier solids and finer cut points
• Tungsten carbide scroll points with wide spacing flights at tapered end create a finer layer of conveyed solids for consistent, uniform separation and maxi-mum solids-control efficiency
• Stainless steel bowl, scroll, com-partment and cover resist corro-sion and provide long service life
• Precision balanced to run at high RPMs for extended periods with greater efficiency, minimizing maintenance and downtime
• Skid mounted, low profile minimizes space requirements
• Effectively removes the finest silts and returns valuable fluids for reuse
• Reduces makeup fluids, dilution, cleanup and disposal costs
• Ideal for any solids-control appli-cation; especially valuable in environmentally sensitive areas
• Rugged construction and corrosion-resistant materials provide long service life and low maintenance costs in the toughest oilfield environments
• Works efficiently with other M-I SWACO equipment to maximize solids control
The heart of an M-I SWACO cen-trifuge is its high-speed, precision-balanced rotating stainless-steel bowl. Inside the bowl, a double-lead spiral-screw conveyor rotates in the same direction as the bowl but at a slightly slower RPM.
Feed slurry enters through a hollow axle at the narrow end and is distributed to the bowl.
Centrifugal force as high as 500 G’s at 1,900 RPM (or 2,100 G’s at 3,250 RPM) holds the slurry against the
bowl wall in a “pool.” Trapped silt and sand-sized particles settle and spread against the bowl wall where they are conveyed to the solids underflow discharge ports by tungsten-carbide-tipped scroll flights. Silt and sand particles exit damp, but with no free liq-uid. The free-liquid phase carries the fine, 2- to 3-micron-size par ti-cles through the nonplugging stainless steel and tungsten-carbide hardfaced-discharge ports.

High-volume solids removal.
The CD-500 CENTRIFUGEcan process up to 200 GPM (757.1 L/min) of drilling fluid.
Variable bowl speed. The bowl speed can be adjusted infinitely from 379 G’s at 1,200 RPM to 2,066 G’s at 2,800 RPM to control particle separation (cut point) for improved solids removal or cleaner effluent:
• At 1,600 RPM and feed rates of 200 GPM (757.1 L/min), it provides a D90cut point of 8 to 12 microns, depending upon the composition of the mud
• At 2,800 RPM and feed rates of 100 GPM, (378.5 L/min) it provides a D90cut point of 3 to 6 microns, depending upon the composition of the mud
Variable-speed pump. Calibrating pump speed with feed rate allows an optimum relationship between the two variables that improves solids-control efficiency.
Programmable Logic Controller (PLC). The PLC makes and monitors speed adjustments and may be housed within an explosion-proof enclosure. RPM readouts of the con-veyor and bowl are displayed at the control panel.
Tungsten-carbide scroll points.
Tungsten-carbide hardfaced points at the tapered end of the scroll protect the conveyor against wear.
Specially designed, widely spaced flights. Conveyor pitch in the conical section is designed
to reduce plugging and promote maximum solids removal at high-differential speeds.
Stainless steel components. The stainless steel bowl, scroll, compart-ment and cover resist corrosion and provide long service life.
Operating safety controls. Safety features include self-limiting vibra-tion and torque switches to protect against catastrophic failure known to occur in other “high-speed”
centrifuges.
Drive options. The centrifuge can be supplied with a number of drives: standard electric, PLC-controlled ; variable-frequency drive;
or hydraulic drive.
Mounting options. For tight-fitting offshore installations, the centri fuge can be supplied with a pedestal mount. For land applications, the low-mount design allows for a simple centrifuge stand with one set of handrails.
Features and Benefits
• Provides precise control over the separation process to accommodate variations in solids loading and material sizes; can be regulated to produce cleaner effluent
• High-volume processing
• Adjustable speeds on bowl, scroll and pump
• Automatic PLC monitoring and adjustment compensates for varied drilling conditions, while reducing operator involvement and effort
• Allows drilling at high ROP
• Runs efficiently at high speeds for prolonged periods
• Rugged construction and corrosion-resistant materials provide long service life and low maintenance costs in the toughest oilfield environments
• Protection against failure at high speeds
• Reduces solids packoff

The FLUIDSPROCESSINGSYSTEM from M-I SWACO is a complete solids-control solution — from shale shakers to centrifuges to D-GASSERunits — strategically combined into a single, skid-mounted unit. Just as important, every FPS comes with a round-the-clock service crew, backed by a system supervisor and on-call technical services engineers.
System integration. Instead of a collection of equipment from various sources, the FPS is a field-proven network of solids-control components specifically designed to function as a single unit.
