Abstract
The present invention relates to systems and methods for controlling the flow of steam provided to a gas recovery unit 130 based on changes to steam flow to and/or power generated by a power generation unit 119. The gas recovery unit 130 may be part of a thermal power generation unit and may be an amine based CO2 recovery unit including two or more regenerator columns 153.
Claims20
A plant, comprising:
- a boiler unit that produces steam;
- a power generation unit comprising at least one power generation turbine that receives the steam from the boiler unit;
- a gas recovery unit comprising two or more regenerator columns;
- a secondary source of steam to the two or more regenerator columns;
- and
- a controller configured to regulate the flow rate of steam to two or more regenerator columns;
- wherein the controller comprises a control strategy that determines the flow rate of steam from the source of steam to each regenerator of the two or more regenerator columns based on a plant load parameter.
4 more elements
A method for providing steam to a gas recovery unit, comprising:
- controlling the flow of steam to two or more regenerator columns of the gas recovery unit based on a load parameter for a power generation unit.
