1. A method of treating recovered fluids in-line, comprising: separating contaminated drill cuttings into drill cuttings and contaminants by applying heat to the contaminated drill cuttings so as to vaporize contaminants from the contaminated drill cuttings;condensing at least a portion of the vaporized contaminants in a first condenser;separating the condensed vapors into a first oleaginous liquid and a first aqueous liquid, wherein at least a portion of one of the first oleaginous liquid and first aqueous liquid is fed back into the first condenser via a first feedback line; andinjecting ozone into at least the portion of the fed back liquid until an optimal weight ozone per gram liquid of the at least the portion of the fed back liquid is reached. 2. The method of claim 1, further comprising: condensing at least a second portion of the vaporized contaminants in a second condenser;separating the second condensed vapors into a second oleaginous liquid and a second aqueous liquid, wherein at least a portion of one of the second oleaginous liquid and second aqueous liquid is fed back into the second condenser via a second feedback line; andinjecting ozone into at least the portion of the second fed back liquid until an optimal weight ozone per gram liquid of the at least the portion of the second fed back liquid is reached. 3. The method of claim 1, wherein the optimal weight ozone per gram liquid is between 4,000 and 14,000 ppm ozone per gram oil liquid. 4. The method of claim 1, wherein the optimal weight ozone per gram liquid is between 4,000 and 8,000 ppm ozone per gram oil liquid. 5. The method of claim 1, wherein the optimal weight ozone per gram liquid is between 1,000 and 4,000 ppm ozone per gram aqueous liquid. 6. The method of claim 1, further comprising monitoring the flow rate of ozone injected into to the fed back liquid. 7. The method of claim 1, further comprising: removing excess ozone from the first feedback line to a ozone destruction unit;converting the excess ozone to oxygen; andventing the oxygen. 8. The method of claim 1, further comprising: controlling at least one of ozone flowrate, ozone pressure, and ozone concentration. 9. The method of claim 2, wherein the optimal weight ozone per gram liquid is between 4,000 and 14,000 ppm ozone per gram liquid. 10. The method of claim 2, further comprising: removing excess ozone from the second feedback line to a ozone destruction unit;converting the excess ozone to oxygen; andventing the oxygen. 11. A method of treating recovered fluids in-line, comprising: separating contaminated drill cuttings into drill cuttings and contaminants by applying heat to the contaminated drill cuttings so as to vaporize contaminants from the contaminated drill cuttings;condensing at least a portion of the vaporized contaminants in a first condenser, wherein at least a portion of the condensed portion of the vaporized contaminants is fed back into the first condenser via a first feedback line;condensing at least a portion of the remaining vaporized contaminants in a second condenser;separating the remaining portion of the condensed vapors into a first oleaginous liquid and a first aqueous liquid, wherein at least a portion of one of the first oleaginous liquid and first aqueous liquid is fed back into the second condenser via a second feedback line; andinjecting ozone into at least the portion of on of the fed back liquids until an optimal weight ozone per gram liquid of the at least the portion of the fed back liquid is reached.
