Patent ID: 8074738

Claim:
A system for offshore treatment of drill cuttings, comprising: a first pressurized vessel configured to receive contaminated drill cuttings and adapted to allow a compressed gas be introduced therein as the sole means for inducing movement of said contaminated drill cuttings in the first pressurized vessel, whereby at least a portion of the contaminated drill cuttings is discharged from the first pressurized vessel; a second pressurized vessel in fluid communication with the first pressurized vessel and adapted to allow a compressed gas be introduced therein as the sole means for inducing movement of said contaminated drill cuttings in the second pressurized vessel, whereby at least a portion of the contaminated drill cuttings is discharged from the second pressurized vessel by positive pressure under mass flow; and a reactor unit in fluid connection with the second pressurized vessel for separating the contaminated drill cuttings into drill cuttings and contaminants, comprising: a processing chamber having at least one inlet and outlet; and a rotor mounted in the processing chamber, comprising: a shaft; and a plurality of fixed rotor arms extending radially from the shaft; wherein the first pressurized vessel, the second pressurized vessel, and the reactor unit are on an offshore rig.
