The invention relates to a solid bowl centrifuge with a horizontal elongated, hollow, rotatable, solid-wall bowl (2) with an inlet and an outlet and a rotatable screw conveyor with a shaft (6) and helical screw (7) rotatable mounted inside said bowl and extending substantially the full length thereof. It is mainly characterized in that on the shaft there are mounted a number of truncated conical discs (24), whereby the discs are directly surrounded by the helical screw. With such design the decanter capacity can be increased and the polymer consumption reduced. Further power consumption can be reduced by obtaining the same performances as the traditional decanter at lower rotational speed (lower g-force).

A horizontal decanter centrifuge for enhanced recovery of drilling mud from drilling mud solids. Oilfield decanters will always suffer some drilling mud losses because they can only achieve a certain effectiveness with respect to solids dryness. The embodiment describes a process to mitigate the financial burden of drilling mud losses by adding a less expensive sacrificial fluid to take the place of drilling mud in the solids phase. A process and apparatus for drilling mud displacement is described including flowing the drilling mud into a horizontal decanter centrifuge, wherein the stresses imposed within the decanter act to force a sacrificial fluid to displace the drilling mud. The embodiment also describes a process wherein vapours or mist are prevented from escaping and becoming airborne into the external atmosphere.
