  • Thermal drill cuttings treatment with weir system
    Patent number: 7306057
    Abstract: A method for treating material, the material contaminated with contaminants, the method including: introducing material with contaminants to a system for remediation including a thermal treatment system, a quench system, a weir tank system and a condensing system; feeding a slurry of the material to the thermal treatment system and heating the material therein producing heated discharge solids and a discharge stream with liquid and solids therein; optionally, discharging the heated discharge solids and feeding them to a mill system; feeding the discharge stream to a quench system producing a cooled discharge stream which is fed to the weir tank system; the weir tank system having a clean side and a dirty side; the cooled discharge stream fed to the dirty side of the weir tank system, and from the weir tank system producing at least one stream of cleaned liquid and a stream with contaminants therein; and, in one particular aspect, remediating drilled cuttings material using such a method.
