The solids may then be treated by either or both of two approaches. One approach involves vaporizing all residual oil and water from the solids, and burning off the vaporized oil. Another approach involves at least partially vaporizing the residual oil from the solids and recondensing the oil. The method produces a solid “soil” product that is free from oil contamination (or is sufficiently decontaminated to allow reuse), an oil product that is fit for reuse, and clean air emissions. A thermal desorber or a soil dryer can be used to efficiently vaporize the oil at low temperature. Optionally the water fraction of the mud can be vaporized, solutes and salts can be captured as evaporite and then be mixed with the soil product. The method has the unique advantage of producing no persistent hazardous waste. The method has the further advantage of requiring no external input of energy if the reclaimed oil is used to provide energy for the process. The method has the further advantage of recycling portions of the drilling mud that would otherwise be subject to disposal. | 05-27-2010 |
