Submodel

Provides the calculations needed to estimate the FOB purchase cost for a Column packed bed in the simulation. The CapExCol submodel uses this submodel when the Column includes a packed bed.

CombustGHG

Submodel

Calculates the GHG emissions from stationary combustion sources in your simulation.

DefCapEx

Submodel

Serves as a template for custom economic CapEx submodels and provides a basic framework for their development.

You can also use this submodel as the default submodel for capital cost economic evaluations. This submodel requires you to specify the estimated FOB purchase cost, which is typically provided by the equipment vendor or supplier. If you do not know the estimated FOB purchase cost, we recommend that you use one of the other CapEx submodels from the Economics Library or a custom CapEx submodel instead.

You must add this submodel to an existing equipment model in the simulation to include the equipment model in the CapEx calculations. You can add this submodel to the equipment model by pressing and holding Shift and then dragging this submodel from the Economics Library onto the equipment model on the Canvas.

DefDeprec*

Serves as a template for defining a custom depreciation schedule of a project. By default, it does not implement a depreciation plan.

DefEcon*

Submodel

Serves as a template for custom economic models and provides a basic framework for their development.

DefEF*

Submodel

Provides a template for specifying the CO2, CH4, and N2O emission factors for a fuel. The EPA Center for Corporate Climate Leadership hosts a GHG Emission Factors Hub (https://www.epa.gov/climateleadership/ghg-emission-factors-hub) that includes current emission factors for GHG inventories.

DefMapWG*

Submodel

Provides a template for mapping a fluid’s components to a standard United States (U.S.) Environmental Protection Agency (EPA) waste gas. You should use this submodel with the WasteCompMap parameter in the WasteGHG model.

ExampleUSGridEF*

Submodel

Provides an example set of CO2, CH4, and N2O emission factors for different electricity e-Grid Subregions in the U.S. The emission factors were taken from the latest data from EPA as of February 2023. (https://www.https://www.ecfr.gov/current/title-40/chapter-I/subchapter-C/part-98#ap40.23.98_19.1)

HorizDrum*
