    Abstract: The waste tail gas fuel emitted from refinery plant in Taiwan e.g. catalytic reforming unit,
    catalytic cracking unit and residue desulfurization unit, was recovered and reused as
    a replacement fuel. In this study, it was slowly added to the fuel stream of a heater
    furnace to replace natural gas for powering a full-scale distillation process. The waste tail
    gas fuel contained on average 60 mol% of hydrogen. On-site experimental results show
    that both the flame length and orange-yellowish brightness decrease with increasing
    proportion of waste gas fuel in the original natural gas fuel. Moreover, the adiabatic flame
    temperature increases as the content of waste gas fuel is increased in the fuel mixture
    since waste gas fuel has a higher adiabatic flame temperature than that of natural gas.
    The complete replacement of natural gas by waste gas fuel for a heater furnace operating
    at 70% loading (i.e. 3.6  107 kcal/h of combustion capacity) will save 5.8  106 m3 of
    natural gas consumption, and 3.5  104 tons (or 53.4%) of CO2 emission annually.
    Recovering and reusing the waste tail gas fuel as natural gas replacement will achieve
    tremendous savings of natural gas usage and effectively lower the emission of carbon
