  • Carbon dioxide capture from a cement manufacturing process
    Patent number: 7976628
    Abstract: A process of manufacturing cement clinker is provided in which a clean supply of CO2 gas may be captured. The process also involves using an open loop conversion of CaO/MgO from a calciner to capture CO2 from combustion flue gases thereby forming CaCO3/CaMg(CO3)2. The CaCO3/CaMg(CO3)2 is then returned to the calciner where CO2 gas is evolved. The evolved CO2 gas, along with other evolved CO2 gases from the calciner are removed from the calciner. The reactants (CaO/MgO) are feed to a high temperature calciner for control of the clinker production composition.
    Type: Grant

  • Directed spray mast
    Patent number: 6889920
    Abstract: Disclosed is an elongated, tubular, compact high pressure sprayer apparatus for insertion into an access port of vessels having contaminated interior areas that require cleaning by high pressure water spray. The invention includes a spray nozzle and a camera adjacent thereto with means for rotating and raising and lowering the nozzle so that areas identified through the camera may be cleaned with a minimum production of waste water to be removed.
