| description | At oil refinery is important evaluate efficiency of combustion process because variability of combustible gas composition, depending of characteristics and conditions at industry.
The combustion process assessment required thermodynamics properties and kinetics in order to know heating value, energy efficiency and emissions generated. These properties have been calculated with computational methods.
In this work has been used software PREMIX for evaluate combustion of representatives mixtures of refining industry; the simulation model used describes an isobaric system, in steady state and unidirectional, and reaction mechanics is carried out using GRI-MECH 3.0. Combustion products, temperature and rates of propagation flame were analyzed in the range of equivalence ratio from 0.8 to 1.8, for natural gas. Results were validated with experimental data carried out in a lab scale reactor. Combustion products show concordance with kinetic mechanism of reaction, adiabatic temperature maximum was 2040 K for stoichiometric equivalence ratio and maximum value for propagation flame rate was 0.007cm/s.
Results obtained by simulation and experimentally show agreement with data reported in the literature for combustion products, temperature and propagation flame rate, it showing that the model used describes combustion process and can be assessed reliably and economically. |
