CALA, O. M.; MERINO, L.; KAFAROV, V.  and  SAAVEDRA, J.. EFFECT OF REFINERY GAS COMPOSITION ON CHARACTERISTICS OF COMBUSTION PROCESS. Rev. ing. univ. Medellín [online]. 2013, vol.12, n.23, pp.101-111. ISSN 1692-3324.

This scientific research article is an analysis of the effect fuel gas composition change (from Refinery Gas to Natural Gas) has on the characteristics of combustion process in industrial oil refining furnaces; heat power, Wobbe Index, and oxygen excess were evaluated for combustible mixtures of variable composition. Through computational simulation of the combustion process, adiabatic temperature of the flame, efficiency, and composition of combustion products were calculated. Mixtures of combustible gases with heat powers between 800 and 2500 Btu/cubic feet were evaluated and compared to natural gas combustion. Variability of adiabatic temperature and efficiency in function of gas composition and oxygen excess occurred; and this resulted in furnace instability and higher environmental impact.

Keywords : Refinery gas; combustion; energy efficiency; fuel.
