  • Publication number: 20180265405
    Abstract: Oil sands drill cuttings waste represents one of the most difficult challenges for the oil sands mining sector. Reducing the amount oil sands drill cutting waste sent to landfill offers one of the best solutions for waste management. The present disclosure provides cementitious formulations comprised of treated oil sand waste for use in geotechnical applications. The cementitious formulations include but are not limited to grouts, cement and controlled low strength materials (CLSM) and in these formulations the treated oil sand waste (TOSW) is used to replace conventional constituents such as some of the fly ash in concrete, some of the cement in grout formulations and some of the fly ash and cement in the controlled low strength materials. The treated oil sand waste is predominantly silicon dioxide (SiO2) which is produced using a process and system which separates water and oil from the solid waste, known as the thermos-mechanical cuttings cleaner (TCC).

  • Patent number: 9785178
    Abstract: A current reference generator includes a first voltage reference configured to generate a first current through a first resistor; a second voltage reference configured to generate a second current; a first current mirror configured to subtract the second current from the first current to generate a temperature invariant current; a third voltage reference configured to generate a third current via a second resistor; and a second current mirror configured to: subtract the temperature invariant current from the third current to produce a process-temperature invariant current, and output the process-temperature invariant current.
