Abstract
A portable system for recovering oil-based fluids from sorbent articles containing oil-based fluids, the system including a motor vehicle and a self-balancing centrifuge having a housing and a foraminous rotatable basket removably attached to a spindle in the housing, the centrifuge being attached to the vehicle for transport to a remote site, the basket having a solid base having a mass sufficient to provide self-balancing rotation of the basket and the basket being configured for receiving a plurality of the sorbent articles therein, wherein rotation of the centrifuge basket applies sufficient centrifugal force to the sorbent articles to cause removal of oil-based fluids therefrom such that the fluids travel from the basket into an annular area between the basket and the housing and from the housing to a fluid recovery tank and the sorbent articles are essentially fluid free.
