Classifying Decanter for Oil & Gas

GEA offers classifying decanters for barite recovery in drilling mud treatment.

Centrifuge - Decanter Centrifuge

Special treatment is required for the heavy mineral barite (barium sulphate), which has a minimum specific density of 4.20 g/cm3. The comparatively expensive barite is added to the drilling mud on board in order to thicken the drilling mud. This rare and valuable mineral would have to be disposed of together with the dried drilling mud if it could not be separately precipitated. In order to recover the precious barite and recycle it back into the process GEA has developed a special classifying decanter. This special decanter removes only very heavy solids from the mud.

In order to recover the precious barite and recycle it back into the process GEA has developed a special classifying decanter. This special decanter removes only very heavy solids from the mud. Our GEA rigMaster CF series from the new ecoforce decanter generation is used for this application – with the inherent advantages such as high torque, maximum availability, high throughput capacities, excellent classifying results and low energy consumption.
