Flue Gas Cleaning Library

FGC_Lib is a model library for modeling flue gas cleaning systems by solving the steady-state mass and energy balances. The aim is to support the basic design of process sequences, the determination of operating conditions and the assessment of the streams of flue gas, additive, by-product and waste with respect to flow, composition, and thermal state.

The performance of the single-unit operations (removal efficiency, the stoichiometry of additive supply, pressure drop, etc..) is to be specified by the user. Flow, composition, and the thermal state of the drain streams result from chemical/thermodynamic models of the particular operation.

DeNOx SCR Process
Nitrogen oxides are removed from the flue gas by selective catalytic reduction (SCR). Aqueous ammonia (ammonium hydroxide) is vaporized and used as the reducing agent.
SNOX Process
The SNOX process (developed by Haldor Topsoe) is based on catalytic reactions and does not consume water or absorbents. Sulfur dioxide, nitrogen oxides and particulates are removed from the flue gas.
Waste Incineration Plant FGC Process
Typical flue gas cleaning process for a municipal waste inceration plant. It consists of an electrostatic precipitator (ESP) for dedusting, a neutral and a sour scrubbing stage, lime, gypsum and waste water processing, and a gas polishing and denitrification (DeNOx) section.
Wet FGC Process
Wet flue gas cleaning process for typical fluegas from a thermal waste incineration plant. It consists of an electrostatic precipitator (ESP), a wet scrubbing section, flue gas reheating and selective catalytic reduction denitrification (SCR DeNOx) using ammonium hydroxide as reducing agent.
