Abstract

A process and apparatus for removing hydrocarbons from hydrocarbon containing drilling waste. The process includes introducing hydrocarbon contaminated drill cuttings into one or more centripetal cuttings separators to create two distinct phases, thereafter discarding the bulk solids containing less hydrocarbons and treating the concentrated liquids phase in a solvent wash apparatus, resulting in improved efficiency of the facility throughput, while not substantially impacting the capital cost or operating cost of a solvent wash process facility. Apparatus for performing the process is also described.
