Plant Performance

← Previous | Next →

The Plant Performance result screen displays performance results for the plant as a whole. Heat rates and power in and out of the plant are given in a two table format.

The table on the left is standard for a Plant Performance result screen. The table on the right, Plant Electricity Requirements, provides a breakdown of the internal power consumption for the individual technology areas. These are all given in units of megawatts. Individual plant sub-components will only be displayed when they are configured on the Plant Design screen. The following results are shown in the table on the right:

•Total Generator Output: This is the gross power generated by the turbine.

•Air Compressor Use: The power required to operate the air compressor.

•Turbine Shaft Losses: This value accounts for any turbine electricity losses other than power used for the air compressor.

•Gross Plant Output: This if the net power generated by the turbine. This is the gross output of the turbine minus the power required by the air compressor and any miscellaneous losses.

•Miscellaneous Power Block Use: This is the power required to operate pumps and motors associated with the power block area.

•Air Separation Unit Use: This is the power utilization of the compressors in the air separation system.

•Gasifier Use: This is the power utilization of the gasification system.

•Sulfur Capture Use: This is the power utilization of the sulfur capture system (this does not include the Claus or Beavon-Stretford systems).

•Claus Plant Use: This is the power utilization of the Claus plant equipment.

•Beavon-Stretford Use: This is the power utilization of the Beavon-Stretford system.

•Component Electrical Uses: Power used by various plant and pollution control equipment is reported in the middle portion of the second column. The number displayed varies as a function of the components configured in the power plant. The following may be displayed, as appropriate:

•Water-Gas Shift Reactor Use

•Chemical Looping Expander Use

•Selexol CO2 Capture Use

•CLC CO2 Capture Use

•Ionic Liquid CO2 Capture Use

•Cooling Tower Use

•Hybrid Cooling System Use

•Air Cooled Condenser Use

•Net Electrical Output: This is the net plant capacity, which is the gross plant capacity minus the losses due to plant equipment and pollution equipment (energy penalties). Also included are credits from steam generated and reused to produce electricity.

•IL Steam Use (Elec. Equiv.): (Only shown when an ionic liquid CO2 capture system is in use.) This is the electrical equivalent energy for the regeneration steam required by the ionic liquid CO2 capture system. It is taken from the steam cycle.
