  • Method for drying oil well drill cuttings
    Patent number: 4387514
    Abstract: A method for drying oil well drill cuttings to eliminate pollution causing organic material from the cuttings includes conveying the drill cuttings bearing the organic material to a heat transfer zone. Large quantities of relatively warm fixed gas are supplied to the heat transfer zone, with the gas functioning as a heat transfer medium. The gas is mixed with the drill cuttings to vaporize water and pollution causing organic material therefrom, with the temperature of the drill cuttings subsequently increasing.
