  • Method and system for controlling a gasification or partial oxidation process
    Patent number: 8951311
    Abstract: A method and system for controlling a fuel gasification system includes optimizing a conversion of solid components in the fuel to gaseous fuel components, controlling the flux of solids entrained in the product gas through equipment downstream of the gasifier, and maximizing the overall efficiencies of processes utilizing gasification. A combination of models, when utilized together, can be integrated with existing plant control systems and operating procedures and employed to develop new control systems and operating procedures. Such an approach is further applicable to gasification systems that utilize both dry feed and slurry feed.

  • System for small particle and CO2 removal from flue gas using an improved chimney or stack
    Patent number: 6648949
    Abstract: A novel stack application for improved carbon dioxide and particle removal/collection from flue gases produced during coal power-generation processes. Flue gas tangential inlet velocity is increased to subject upward-flowing flue gas in a stack to a centrifugal force, thereby propelling entrained solid particles and CO2 in the flue gas to the stack wall for collection. Collection efficiency is further improved by a cascading water film or algae-laden water film on the inside of the stack wall and on surfaces of an optional internally mounted vortex generator to eliminate the re-entrainment of small particles and for ease of transporting the captured particles in a slurry. The stack can also be utilized as a photochemical or a biological reactor to promote a photosynthesis reaction between carbon dioxide and algae-laden water to form carbohydrate substrates for carbon dioxide sequestration and utilization.
