Abstract
The present invention relates to systems and methods for providing steam 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 part of a thermal power generation unit 100 and may be an amine based CO2 recovery unit including two or more regenerator columns 153.
Claims21
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;
- and
- a secondary source of steam providing steam to each of the two or more regenerators columns at different rates.
