Curtis Laush, Ph.D.

Curtis Laush is a Senior Physical Chemist based in Tennessee with more than 20 years of professional experience focused on the detailed analysis, monitoring, tracking, and management of air emissions produced by electric utilities, solid waste storage facilities, manufacturing plants, and similar industrial operations.


As a trained gas phase chemist, Curt leads field measurement services and consults on maintenance services for air sampling technology. He also conducts training, provides data interpretation and reporting, and leads applied development of new techniques for air monitoring and measurement. Curt also applies his knowledge of remote sensing technology, quantitative measurement methods, and the installation of advanced instrumentation for clients around the world facing environmental and regulatory challenges related to air emissions.

Curt has applied a powerful measurement technique, called Fourier Transform Infrared (FTIR) spectroscopy, to study the emissions produced by power plants across the United States. This type of spectroscopy allows him to precisely quantify the total composition of flue gas species concentrations. The technique, along with Curt's applied research experience in the handling of gas phase and aerosol-based acids (including sulfuric, hydrochloric, hydrobromic, and hydrofluoric acids) have proven valuable in helping power plant operators better understand potential exhaust system corrosion and clogging issues as well as the potential for impacts to their mercury abatement systems and selective catalytic reduction (SCR) devices used to manage nitrogen oxide (NOx) emissions. His latest project involves the development of a low-cost, continuous FTIR monitoring system for the complete characterization of sulfuric acid, in both vapor and mist forms, emerging from wet scrubbers and stacks at various concentration levels.

Curt also applies laser-based monitoring techniques, such as tunable diode and quantum cascade lasers, in order to achieve in situ measurement of highly reactive sulfur trioxide and ammonia slip at SCR locations where flue gas temperatures are considered extreme. He has deployed these techniques as short-term measurement devices as well as permanently installed continuous emission monitors.

To continue to advance the state of the practice, Curt is a member of the American Chemical Society, the Air and Waste Management Association, and the Society of Applied Spectroscopy. He continues to advance the state of the practice through frequent publications and presentations on the underlying chemistry of air emissions. He is a listed author on more than 20 publications and patents.
