Process for treating waste drilling mud

摘要: A method is provided of recycling and cleaning up oil-based waste drilling mud cuttings contaminated with mud. facility for performing the also provided. The includes removing coarse solids from mud, breaking emulsion, separating hydrophobic phase water solid phase, vaporizing all residual oil solids, burning off vaporized oil. produces a “soil” product that free contamination, an fit reuse, clean air emissions. thermal desorber can be used to efficiently vaporize at low temperature. Optionally fraction vaporized, solutes salts captured as evaporite then mixed soil product. has unique advantage producing no persistent hazardous waste. further requiring external input energy if reclaimed provide process. portions would otherwise subject disposal.
