ABSTRACT:
An onsite method and apparatus for treating oil-contaminated drill cuttings at an onsite location, e.g., offshore drillsite, whereby the cuttings can be disposed of directly without the risk of pollution. The contaminated cuttings are separated from the drilling mud and are passed to a heating section of a treating unit where they are sprayed with steam to flash distill the oil from the cuttings. The distilled oil and the spent steam are passed to a cooling section of the treating unit where they are condensed before being passed to a water-oil separator. The cleaned cuttings are removed from the heating section for disposal, e.g., by dumping them into the water if at an offshore location.
