Inputs for the configuration of the pipeline transport system for all plant types are entered on the Config parameter screen. The following parameters are available:

•Pipeline Region: The capital (labor portion) and O&M costs are dependent on the US region of the country where the pipeline is built. These regions are based on the EIA natural gas pipeline regions. Possible values are:

•Central US

•Midwest US (This is the default.)

•Northeast US

•Southeast US

•Southwest US

•Western US

•Total Pipeline Length: This is the total length of the pipe between the plant site and the sequestration site.

•Net Pipeline Elevation Change (Plant->Inj.): The pipeline may traverse hilly terrain; this is the overall elevation change from plant site to injection site.

•Number of Booster Stations: The cost of CO2 transport may be lowered by adding booster stations for longer pipeline lengths. This is the number of those stations that are to be modeled.

•Compressor/Pump Driver: This is the type of motor that drives the compressor or pump; electric, diesel or natural gas.

•Booster Pump Efficiency: This is the efficiency of the pump, and accounts for all frictional losses.

•Design Pipeline Flow (% plant cap): This is the flow of liquid CO2 that the pipeline has been designed to handle as a percent of the total that the plant is capable of producing.

•Actual Pipeline Flow: This is the amount of liquid CO2 that flows through the pipeline in tons per year.

•Inlet Pressure (@ power plant): This is the inlet pressure for the transport system. It is determined by the CCS system and is typically shown on one of the parameter screens for that system. (Configuring the CCS system without a CO2 product compressor will result in insufficient pressure in many cases.) It is shown here for reference only.

•Min Outlet Pressure (@ storage site): This the minimum outlet pressure of the CO2 at the storage site.

•Average Ground Temperature: This is the average temperature of the ground where the pipeline will traverse.

•Pipe Material Roughness: The roughness measure is the average size of the bumps on the pipe wall, for commercial pipes this is usually a very small number. Note that perfectly smooth pipes would have a roughness of zero.
