    Topic: Invalid denominator units for emission factorSubscribe | Previous | Next
  • Hapsari Damayanti 8/22/2021

    Dear LEAP team,

    Based on this link: https://leap.sei.org/help/IBC/Using_IBC.htm, I am constructing my model based on the Asiana area so that I can perform IBC calculation. However, this error box always came up every time I ran the result:

    "invalid denominator units for emission factor
    Branch: Demand\industry\iron and steel\natural gas"

    LEAP then always opened the final energy intensity tab on my industry demand module. I assume that there is something wrong with the unit of which I am using BOE/metric tonne. This did not happen when I build the model from scratch (not using the Asiana area). What am I supposed to do with this?

    Your response is very much appreciated.

    This most likely indicates that natural gas does not have a specified density value, in which case LEAP is unable to convert among, mass and volume units. Either specify your emission factors per unit of energy (eg. /TJ) or specify a density value for Natural Gas n the General: Fuels screen.
