Hydrocarbon contaminants in drill cuttings generated in an oil drilling operation are removed by mixing the drill cuttings with an agglomerant (124) to produce a pre-treatment mixture (126); heating (140) to vaporize the hydrocarbon contaminants under a condition in which vapor entrainable particles of the drill cuttings are agglomerated by the agglomerant, and caking of drill cuttings is inhibited; drill cuttings having a reduced content of the contaminant are removed (180), and vaporized hydrocarbons having a reduced content of vapor entrainable particles are recovered (160). In this way, the particulate content of vapors escaping from the drill cuttings is reduced.
Les contaminants hydrocarbures se trouvant dans des d~blais de forage g~n~r~s dans une op~ration de forage p~trolier sont extraits par m~lange des d~blais de forage ~ un agglom~rant (124) afin de produire un m~lange de pr~traitement (126), par chauffage (140) afin de vaporiser les contaminants hydrocarbures dans une condition dans laquelle les particules des d~blais de forage pouvant Útre entra¹n~es par la vapeur sont agglom~r~es par l'agglom~rant, et l'agglutination de d~blais de forage est empÚch~e; les d~blais de forage ayant une teneur r~duite en contaminant sont extraits (180), et les hydrocarbures vaporis~s ayant une teneur r~duite en particules pouvant Útre entra¹n~es par la vapeur sont r~cup~r~s (160). Ainsi, la teneur en particules des vapeurs s'~chappant des d~blais de forage est r~duite.
