NEA offers a suite of software products based on truly comprehensive reaction mechanisms. For that reason, they have already interpreted most of the reported laboratory database on coal conversion kinetics; and provided the reaction rates and product distributions to accurately simulate how fuel quality affects emissions and trace species in furnaces and gasifiers at both pilot and commercial scale. And all of NEA’s packages execute in seconds on ordinary PCs.
FLASHCHAIN® is NEA’s core intellectual property. This reaction mechanism predicts complete distributions of all major primary devolatilization products as well as the subsequent decomposition of primary tars into additional gases, oils, and soot. It is the most thoroughly validated devolatilization mechanism ever devised, simply because a fuel’s proximate and ultimate analyses are the only sample-specific input data requirements. FLASHCHAIN® is suitable for any coal, any form of biomass, and any petroleum coke at any operating conditions.
Our flagship package is PC Coal Lab®, which accurately predicts devolatilization and the conversion of char and soot from virtually any solid fuel at any operating conditions, provided that fuel heating rates are faster than about 1°C/s. This package covers the entire operating domain for p.f. furnaces, CFBCs, AFBCs, PFBCs, entrained-flow gasifiers, fluidized bed gasifiers, and hydrogasification units. With the absolute minimum of laboratory support, PC Coal Lab® enhances your CFD simulations and process design applications to depict the distinctive behavior of individual solid fuel samples.
The NOXLOI Predictor™ uses PC Coal Lab® to forecast how a fuel switch – from a coal or coal blend to other coals or blends of coal-on-coal or pet coke-on-coal or biomass-on-coal – will affect NOX and unburned carbon emissions.
When your application demands full chemistry use ChemNet™ CFD Post-Processing to connect the power of PC Coal Lab® with hundreds of reactions in the gas phase and tens of reactions on soot, to accurately predict any important gaseous emission and trace syngas components.
NEA offers two options to estimate Hg emissions from commercial utility gas cleaning systems. iPOG™ makes “quick and dirty” estimates with minimal input specifications, and is well-suited for non-specialists who want to quickly rank order their Hg control options. MercuRator™ is our pro-package that accounts for detailed design specifications and site-specific factors, and delivers the better accuracy needed to formulate a Hg control strategy for a particular gas cleaning system.
