  • STABILIZING CONTAMINANTS IN DRILL CUTTINGS
    Publication number: 20150345263
    Abstract: Drill cuttings obtained from oil and gas wells contain contaminants such as heavy metals and volatile organic compounds (VOCs). Such contaminants complicate the disposal of the drill cuttings. The drill cuttings can be reused in load bearing applications such as road subgrades and drill site pads by combining the drill cuttings with soil and a soil stabilizer. The soil stabilizer includes sulfuric acid and citrus stripper oil. Once the soil stabilizer is added to the soil-cuttings mixture, the mixture is compacted to reduce the voids. The soil stabilizer liquefies minerals in the soil-cuttings mixture which liquids fill in any remaining voids. The result is a consolidated treated soil that greatly reduces the leaching of the contaminants therefrom.

  • Asphaltic concrete and method of making same
    Patent number: 6730158
    Abstract: A composition of asphaltic concrete and the method of making the same are disclosed. The asphaltic concrete has asphalt cement, sulfuric acid and citrus stripper oil admixed together. This admixture is mixed with some aggregate and then packed and consolidated. The resulting paved surface resists rutting and requires less maintenance.
