Abstract
Hydrocarbon contaminants in drill cuttings generated in an oil drilling operation are removed by mixing the drill cuttings with an agglomerant to produce a pre-treatment mixture; heating 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, and vaporized hydrocarbons having a reduced content of vapor entrainable particles are recovered. In this way, the particulate content of vapors escaping from the drill cuttings is reduced.
