The Plant
What distinguishes the MKIIIV²D²C² from the standard MKIII Plant is the addition of separation components (vibrating screens, decanters and centrifuges) to add capacity. The MKIIIV²D²C² for example has twice the capacity of our standard MKIII. The treating concepts are the same in that G-force plants are designed to treat all hazardous classified oily waste by-products generated as a result of core oilfield industries involving Drilling, Production and Refining operations. These waste are defined from oil base drilling fluids, drill cuttings, production fluids, produced water, slop oils, oil emulsions, tank bottoms, oil skimmings, sludge pits and accidental oil spills. The concept of treatment involves mobilization of oily waste to the plant where the process begins by sorting of large particles and debris, and the introduction of high “g” separators (screens, decanters and centrifuges) that work to remove all solid sediments and end the process by splitting the oil and water into recyclable product so that oil is returned to market and water-solids are returned to nature. The plants are designed under the new EU ATEX 2 norm for explosion proof equipment compliant with oilfield zoning. A special design feature is the interconnecting pipe rack where all plant components centrally flange thereby minimizing space requirements, making installation and commissioning a quick, simple and easy task and providing excellent operations logic for all waste materials being fed into and process through the various plant operation phases.
 

Principle of Operations
Waste materials of liquid, semi-liquid, semi-solid and pre-process solids are fed directly to the plant, either through the MKJ (semi-solids materials) or directly to the MKIII vibrating screens for liquid & semi liquid materials. Large size debris and particles are removed at the MKJ and MKIII vibrating screen. From there the liquids are pumped to a 2-phase decanter with up to 3000 G-force for removal of particles down to 5.0 microns so that the clarified effluent is ready for treatment in the 3-phase centrifuge. The 3-phase centrifuge with up to 6000 G-force separates oil, water and the remaining solids. The oil is cleaned to meet refinery specification, the water cleaned for return to the refinery water treatment facility, and solids are minimized to reduce the overall portion of waste left for final declassification. Standard size G-force MKIII plants are designed for waste treatment capacities of 5 m³/hr. Custom plants, to meet smaller and/or larger capacities, are built to suit the specific need of our customers, such as this MKIIIV²D²C².

Serviceability
The plants are supplied with one-year of spares and come with a recommended maintenance schedule based on each 2000 hours of operations (4 times per year). All primary equipment is supplied as a complete package including special tools and is ready for installation on a level concrete pad. No other requirements are needed except to bring service points to the concrete pad for hook up purposes. G-force also supplies all climate buildings dimensionally specific for the plant size supplied.
 

Dimensions and Utilities
Basically, if the client orders a plant with a G-force heat supply, the utility requirement is electrical power, diesel (or fuel oil) & plant water. If the client has a steam supply only electricity and water are needed. The kW and water depend on plant size and options chosen, details of which are provided with our quotations. The concrete pads for the standard plant sizes are shown on the reverse side of this document.
