Subpart G requires a facility to report annual CO2 process emissions from each process unit used to produce ammonia. To calculate the annual CO2 emissions from each process unit, users must use one of three equations based on the unit feedstock. Users may use different spreadsheet tools for different process units as required by the feedstock type for each unit. Users may use more than one spreadsheet tool for a process unit if the unit has more than one type of feedstock.
For each process unit with a gaseous feedstock, users should calculate annual CO2 process emissions using Equation G-1 and the G-1 Spreadsheet Tool. Equation G-1 is provided below:
(Equation G-1) |
|

For each process unit with a liquid feedstock, users should calculate annual CO2 emissions using Equation G-2 and the G-2 Spreadsheet Tool. Equation G-2 is provided below:
(Equation G-2) |
|

For each process unit with a solid feedstock, users should calculate annual CO2 emissions using Equation G-3 and the G-3 Spreadsheet Tool. Equation G-3 is provided below:
(Equation G-3) |

Use the G-1 Spreadsheet Tool to calculate the annual CO2 process emissions from a process unit with a gaseous feedstock. A separate spreadsheet is to be used for each process unit. Calculations for process units with liquid and solid feedstocks should be performed using different spreadsheet tools and different equations. The G-1 Spreadsheet Tool performs the calculation using Equation G-1, provided below.
(Equation G-1) |

Begin by entering the facility name, your name, the process unit name or identifier, process unit description, and any additional comments in the green input cells of the General Information table located immediately below the equation in the spreadsheet tool. This is for your records.
...
The spreadsheet tool will calculate the Annual CO2 process emissions from a unit with a gaseous feedstock. This calculated value will be displayed in the red-bordered cell in the G-1 Results table at the bottom of the spreadsheet. This value should be entered in e-GGRT for this process unit.
