About IECM
IECM is a computer-modeling program that performs a systematic cost and performance analyses of emission control equipment at coal-fired power plants. The IECM allows the user to configure the plant to be modeled from a variety of pollutant control technologies:
Power Plants
- PC Boilers (sub, super, and ultra-super-critical)
- Integrated Gasification & Combined Cycle (IGCC)
- Natural Gas Combined Cycle (NGCC)
- Oxyfuel Combustion
NOx Control
- Tangential, Wall and Cyclone Firing
- Low NOx Burner (LNB)
- Selective Catalytic Reduction (SCR)
- Selective Non-Catalytic Reduction (SNCR)
- Natural Gas Reburn
SO2 Control
- Acid Gas Removal w/ Sulfur Recovery
- Wet Limestone w/Forced Oxidation
- Wet Limestone with Dibasic Acid Additives
- Lime Spray Dryer
- Mg-Lime Process
Particulate Matter Control
- Electrostatic Precipitator (ESP)
- Reverse Gas Fabric Filter
- Reverse Gas Sonic Fabric Filter
- Shake and Deflate Fabric Filter
- Pulse-jet Fabric Filter
Mercury Control
- Activated Carbon Injection
(with and without spray cooling)
- Intrinsic Capture of Mercury by
Other Control Technologies
CO2 Capture & Storage
- Amine Scrubber
- Pipeline Transport
- Enhanced Oil Recovery Storage (EOR)
- Deep Saline Reservoir Storage
- Ocean Storage
- Enhanced Coalbed Methane Storage
- Water-Gas Shift Reactor
- Selexol Scrubber
- O2-CO2 Recycle (Oxyfuel)
A unique capability of the IECM model is that it allows uncertainty of performance
and costs to be characterized for key design criteria. The uncertainties can be iterated across
the entire emission control system.
