INDUSTRIAL RESEARCH EXPERIENCE
1975 to 1981
Argonne National Laboratory,
Assistant Chemical Engineer (November 1978 to June 1981)
Engineering Assistant (June 1975 to October 1978)
- Contributed elutriation and attrition chapters to a DOE guidebook
about sulfur control in fluidized bed combustors. Over five hundred
copies of the report were distributed to DOE laboratories, universities,
and commercial research facilities.
- Coordinated long-term (100 and 1000 hour) studies in the pilot
plant combustor. Planned installation and operation of experimental
equipment for the biology and material science divisions taking part in
the study. The studies demonstrated a 40 to 60 percent savings in
limestone used by the fluidized bed combustor.
- Planned two projects with outside contractors.
- Directed studies of hydration of spent limestone at the
Grand Forks Energy Technology Center. Increased limestone
conversion by 200 percent.
- Directed the installation of an experimental $100,000 laser
Doppler particle size analysis system at the Westinghouse Waltz Mill
facility. Trained two senior engineers and other Westinghouse staff in
equipment operation. Completed the installation in one week.
Westinghouse personnel completed a two month test of the instrument.
- Studied defluidization during reductive decomposition of sulfated
limestone. Defined conditions causing catastrophic failure of the
- Developed FORTRAN process models for fluidized bed combustion and
sorbent regeneration systems. Process costs and flowsheets computed
using these models showed economic viability of fluidized bed
burners for an 810 MWatt electric power plant.
- Carried out experimental studies of a system for regenerating
limestone for recycle to a fluidized bed combustor. Demonstrated that
limestone requirements could be cut by a factor of six with a 3 percent
increase in coal consumption.
- Specified $100,000 of analytical, control, and data
acquisition equipment for a new laboratory fluidized bed pilot plant.
The control systems allowed twenty-four hour operation of the
fluidized bed combustor for long-term experimental studies.
- Developed and tested the PL/1 data acquisition and analysis
programs for the new laboratory.
- Evaluated two laser particle size analyzers for on-line analysis
in the fluidized bed pilot plant. The evaluation showed
the Mie scattering instrument suitable for on-line measurements at
high dust loading in the flue gas. The first-generation
laser Doppler instrument had a more limited range of operation.
- Extended FORTRAN and PL/1 programs for data acquisition in
a fluidized bed pilot plant. The added capabilities speeded preparation
of graphs for final technical reports.
