  • Patent number: 10155190
    Abstract: A system for reducing carbon dioxide emissions from a flue gas is provided. The system includes a carbonator, and a calciner. The carbonator receives the flue gas and lean sorbent particles such that the lean sorbent particles absorb gaseous carbon dioxide from the flue gas and become loaded sorbent particles. The calciner includes a drum that defines a cavity having a first opening and a second opening. The first opening is fluidly connected to the carbonator such that the loaded sorbent particles flow into the cavity from the carbonator. The drum rotates such that at least some of the loaded sorbent particles are mixed with heat-transferring particles so as to release the absorbed gaseous carbon dioxide and exit the drum via the second opening as lean sorbent particles.

  • Publication number: 20170326569
    Abstract: A system for regulating the viscosity of a fluid prior to atomization includes a temperature controller configured to adjust a temperature of a fluid flowing in a conduit prior to atomization of the fluid by an atomizer fluidly connected to the conduit and a sensor in communication with the temperature controller such that the sensor can provide an indicator to the temperature controller of a viscosity of the fluid flowing in the conduit prior to atomization. An adjustment to the temperature of the fluid by the temperature controller is based at least in part on the measured viscosity indicator of the fluid, a target atomization-viscosity of the fluid, and a coking temperature of the fluid.
