T&S Config

← Previous | Next →

The T&S Config parameter screen in PC and NGCC plants characterizes the compression and storage methods for the product CO2. A separate pipeline model is provided to specify inputs for the Pipeline Transport sub-system.

The standard parameters for transport and storage methods are at the bottom of the screen.The following additional parameters are provided:

•CO2 Product Stream: The concentrated CO2 product stream obtained from sorbent regeneration is compressed and dried using a multi-stage compressor with inter-stage cooling.

•CO2 Product Pressure: (Only shown when a CO2 product compressor is configured.) The CO2 product may have to be carried over long distances. Hence it is necessary to compress (and liquefy) it to very high pressures, so that it may be delivered to the required destination in liquid form and (as far as possible) without recompression facilities en route. The critical pressure for CO2 is about 1070 psig. The typically reported value of final pressure to which the product CO2 stream has to be pressurized using compressors before it is transported is about 2000 psig.

•CO2 Product Purity: This is the percentage of the product that is carbon dioxide.

•CO2 Compressor Efficiency: (Only shown when a CO2 product compressor is configured.) This is the effective efficiency of the compressors used to compress CO2 to the designated pressure.

•CO2 Unit Compression Energy: (Only shown when a CO2 product compressor is configured.) This is the electrical energy required to compress a unit mass of CO2 product stream to the designated pressure. Compression of CO2 to high pressures requires substantial energy and is a principle contributor to the overall energy penalty of a CO2 capture unit in a power plant.
