The GHG information required for NGL Fractionators includes four steps:
- #Step Step B1 - Indicate NGL Products Supplied
- #Step Step B2 - Calculation Methodology
- Step B3:
- #Step Step B4 - Equation NN-7 Summary and Results
- #Step Step B5 - Equation NN-8 Summary and Results
...
By default, all products will be selected for you. To deselect a product that you do not supply locate the the check box to the left of the name of the product and click on it.
...
Use the radio buttons to select the methodology used to calculate the potential CO2 quantities quantity associated with the complete combustion or oxidation of this product.
Methodology 1 uses a higher heating value and CO2 emissions factor based on heat content to calculate the CO2 quantities quantity associated with this product.
Methodology 2 uses a CO2 emissions factor based on based on product volume to calculate the CO2 quantities quantity associated with this product.
Based on your selection, e-GRRT will use either Equation NN-1 (if Methodology 1 is selected) or Equation NN-2 (if Methodology 2 is selected) to calculate the potential CO2 quantities quantity associated with this product.
...
This section provides instructions for users that selected Methodology 1 in Step B1. If you selected Methodology 2 in Step B1, skip to Step B2B3.2: Equation NN-2 Summary and Results.
If you selected Methodology 1 in Step B1, e-GGRT will guide you to the page containing Subpart NN Eq. NN-1 where you can use the radio buttons to indicate the source of reported the CO2 quantities quantity associated with this product.
