We are a leading technology company engaged in the worldwide development, commercialization
and application of state-of-the-art proprietary technologies for air pollution
control, process optimization, combustion efficiency and advanced engineering
services. These technologies enable our customers to operate efficiently in
a cost-effective and environmentally sustainable manner. We operate as a fully
integrated company with a capital projects business to leverage our Air Pollution
Control (APC) technologies and a specialty chemicals business which builds upon
our proprietary FUEL CHEM® processes. Both segments rely heavily on our
unique ability to inject chemical slurries into combustion units, in precise
concentrations and locations, to achieve a desired outcome.
Our APC technologies include advanced combustion modification techniques including
low NOx burners and over fire air systems, along with post-combustion nitrogen
oxide (NOx) control approaches, including NOxOUT® and HERT™ Selective
Non-Catalytic Reduction (SNCR), Advanced Selective Catalytic Reduction (ASCR)
system and I-NOxTM Integrated NOx Reduction Systems, which utilize various combined
proprietary technologies to provide a cost effective alternative to high capital
cost, standalone conventional SCR systems. Our patented ULTRA™ system
generates ammonia on-site for SCR systems using safe urea reagent. Our SCR group
provides process design optimization, performance testing and improvement, and
catalyst selection services for SCR systems on coal-fired boilers. These technologies
have established us as a leader in NOx reduction, with installations on over
1,000 units worldwide, where coal, fuel oil, natural gas, municipal waste, biomass,
and other fuels are utilized. Our technologies for particulate control include
Electrostatic Precipitator (ESP) products and services including ESP inspection
services, performance modeling, and performance and efficiency upgrades, along
with complete turnkey capability for ESP retrofits, with more than 60 major
rebuilds on units up to 700 MW. Our flue gas conditioning (FGC) systems involve
sulfur trioxide (SO3) and ammonia (NH3) conditioning to improve the performance
of ESPs by modifying the properties of the fly ash particle. FGC systems offer
a lower capital cost approach to improving ash particulate capture versus the
alternative of installing larger ESPs or utilizing fabric filter technology
to meet targeted emissions and opacity limits. Our particulate control technologies
have been installed on more than 125 units worldwide.
APC technology service offerings include a range of combustion optimization
services, including airflow testing, coal flow testing and boiler tuning, as
well as services to help optimize SCR system performance, including catalyst
management services and ammonia injection grid tuning. In addition, flow corrective
devices and physical and computational modeling services are available to optimize
flue gas distribution and mixing in both power plant and industrial applications.
Our FUEL CHEM technologies revolve around the unique application of chemical
injection programs which improve the efficiency, reliability, fuel flexibility
and environmental status of combustion units by controlling slagging, fouling,
corrosion, opacity and acid plume, as well as the formation of sulfur trioxide
(SO3), ammonium bisulfate, particulate matter (PM2.5), and carbon dioxide (CO2).
We use our patented TIFI® Targeted In-Furnace Injection™ processes
to apply specialty chemical programs to units burning a wide variety of fuels
including coal, heavy oil, biomass, and municipal waste. These TIFI programs
incorporate design, modeling, equipment, reagent, and service to provide complete
customized on-site programs designed to improve plant operations and provide
a return on investment in addition to helping meet emission regulatory requirements.
Many of our products and services rely heavily on our computational fluid dynamics
and chemical kinetics modeling capabilities, which are enhanced by internally
developed, high-end visualization software. These capabilities, coupled with
our innovative technologies and multi-disciplined team approach, enable us to
provide practical solutions to some of our customers most challenging issues.
