摘要： Methods and systems for removing drilling fluid from wet drill cuttings are described. According to some embodiments, the method comprises: at a pressure above atmospheric pressure: using an internal combustion engine, combusting an air-fuel mixture comprising air and a hydrocarbon-based fuel, thereby producing a combustion exhaust at a first temperature; providing the combustion exhaust to the wet drill cuttings to contact and directly heat the wet drill cuttings by convection so that at least some fluid is evaporated therefrom and at least some dry solid drill cuttings remain, the evaporated fluid comprising drilling fluid and water; condensing at least a portion of the evaporated fluid to produce condensed drilling fluid, water and non-condensable inert gas; and separately recovering the condensed drilling fluid, the water and the dry solid drill cuttings.
