Microwave treatment technology for oil contaminated drill cuttings

摘要

This paper introduces the microwave treatment method for the oil contaminated drill cuttings. The method could lead the oil content to reduce to less than 1%, and the oil recovery rate could reach 51.53%. A large amount of oil and water mixed vapor are separated from the cuttings when they are heated to 125°C. Therefore, the oil in the cuttings is carried over by water steam and removed at lower temperatures.
