  • Patent number: 9695050
    Abstract: Systems and methods are provided for processing metal sulfate compounds and sequestering CO2. These systems and processes involve one or more electrochemical cells for producing an alkali-containing catholyte and involve a CO2 absorption reactor operatively connected to the electrochemical cell and to a CO2 source. The CO2 absorption reactor receives the alkali-containing catholyte and CO2 gas for forming an alkaline carbonate solution. The alkaline carbonate solution is directed to a vessel where it reacts with an acidic sulfate solution comprising metal ions resulting in precipitation of solid metal carbonate compounds. The acidic sulfate solution may comprise sulfide leachates from acid mine drainage, sulfide mine tailings and/or reacted pyrite concentrate. The acidic sulfate solution may be circulated through an optional SO2 reduction reactor prior to reaction in the vessel. The SO2 reduction reactor reduces trivalent metal compounds present in the acidic sulfate solution to divalent metal compounds.

  • Patent number: 9695727
    Abstract: System and method of treating exhaust gas from an internal combustion engine using selective catalytic reduction (SCR) and adaptive control of diesel exhaust fluid (DEF) injection. Adaptive control of DEF injection includes intentionally underdosing the injected DEF based on an amount of DEF determined by an electronic control unit as an amount needed to reduce nitrogen oxides (NOx) to a compliance threshold. Since underdosing prevents ammonia (NH3) slip from occurring due to low levels of DEF, a sensor accurately senses NOx present in the exhaust gas at an output of an SCR chamber. An electronic control unit increases the amount of injected DEF based on the sensor.

  • Patent number: 9687779
    Abstract: Sodium borohydride (NaBH4) may be used to removing carbonyl sulfide (COS) from a process stream containing it. The method involves contacting the process stream with an amount of effective of NaBH4 to react with the COS to form reaction products that may be removed by a process of washing away the reaction product by an aqueous basic compound and/or the reaction product having a higher boiling point than carbonyl sulfide which permits trapping the reaction product, such as in a caustic tower.
