ABSTRACT:
A method and apparatus for removing and treating hydrocarbon-contaminated drill cuttings suspended in drilling mud so that the cuttings are made environmentally acceptable while the hydrocarbon contaminants are contemporaneously captured and returned for use in said drilling mud is disclosed. Using one or more shakers to make a first separation of the cuttings from the mud, a mud stream and a first slurry containing cuttings are produced. The mud stream is fed into a mud pit, while the first slurry is fed into a classifier/grit dewatering unit to separate the cuttings from the slurry to obtain a drill solids discharge. The drill solids discharge is passed into a rotating, heat-jacketed trundle for a time and at a temperature sufficient to vaporize the hydrocarbon contaminants to obtain processed solids and hydrocarbon vapors. The hydrocarbon vapors are captured and condensed to obtain a liquid hydrocarbon, which is delivered to the mud pit for admixture with the mud stream.
