Selected Achievements

Achieved $20M in savings in initial capital investment and $3M per year on operating cost by optimizing dry sorbent injection technology to reduce SO2/HCl over 90%. Planned, managed, and executed implementation of this technology.

Cut fuel costs by $3M-$5M each year by designing proper burners for renewable fuels, such as wood waste, biosolids, peanut shells, and tire derived fuels.

Destroyed more than 80% of total hydrocarbons and organic hazardous air pollutants at one cement plant by implementing the industry’s first catalytic filter system, which extended the permit to operate one more year.

Saved $3.3M per year at two cement plants by optimizing reagents for NOx emissions control.

Professional Experience

CEMEX, Inc. – Houston, TX 2005 –2019

Corporate Technical Manager, Chemical Processes

Led process optimization, air pollution control and sustainability projects at 14 cement manufacturing plants.

Managed project to design advanced technological solutions which met compliance goals while cutting costs, protecting consumers/staff, and minimizing ecological impact.

Analyzed complex cement kiln data to identify opportunities for improvement and then implemented solutions.

Created and followed up on action plans to implement solutions plant wide; set clear benchmarks to maximize success rate.

Calculated CO2 emissions for all 14 plants and prepared reports for state/federal agencies.

Collaborated with equipment vendors to align service objectives.

Earned President’s Award in 2016 for achieving compliance with NESHAP regulations.

Extended operation for two cement kilns through identification and implementation of raw material substitution, and installation of a catalytic filter which ensured compliance with total hydrocarbons.

Reduced operations costs by more than $1M annually by applying CFD modeling techniques to design, troubleshoot, and optimize cement plant operations.

Designed and implemented strategy for 14 plants to achieve compliance with EPA NESHAP requirements.

Achieved more than 30% fossil fuels substitution with renewable fuels (fired equipment).
