Control-technology assessment for coal gasification and liquefaction processes
The control technology available to prevent exposure to harmful substances during coal-conversion operations is evaluated for the TOSCOAL Coal Pyrolysis Process which is being developed at the Tosco Rocky Flats Research Center, located in Golden, Colorado. In this process, crushed dry coal is preheated in lift pipes. Hot flue gas from the ball heater supplies the heat. Preheated or partially deagglomerated coal is fed to a rotating pyrolysis drum, where it is contacted with hot ceramic balls and heated in a ball heater fired by clean process-drived fuel gas or fuel oil. Potential hazards exist through possible exposure to noise, heat stress, high temperatures, flammable or explosive materials, respirable coal and char dust, coal tar pitch volatiles, and toxic gases such as carbon monoxide and hydrogen sulfide. The major way to eliminate, or at least minimize, possible exposure to these hazards is through the use of a closed-system operation. The potential hazards associated with coal pulverizing, slurry preparation, hydrogenation, and solid-from-liquid separation do not apply as they are not used in the TOSCOAL process.
