Oil contaminated substrate treatment method and apparatus |
| abstract |
A method and apparatus for treating for disposal oil contaminated substrates, such as drill cuttings from drilling with an oil-based mud, by steam distillation. If necessary, the contaminated substrate (10) can be pretreated with an emulsion breaker (14). The contaminated substrate (10) can be treated with steam (16) in a first mixing still (12). The substrate can be optionally treated with a second steam source (20) in a second mixing still (18). The steam provides heat to vaporize the oil, moisture to treat the substrate and water to the reaction mixture. Recoverable constituents in the vapor can be condensed in a vapor collection system (24). The treated substrate (22) is essentially free of oil and can have a controlled water content. The process exhibits low energy consumption, rapid treatment, compact equipment and a high degree of process control. |
