Abstract
Described is a system for capturing and recovering carbon dioxide (CO) from multiple distinct waste heat sources. The system includes an absorber for extracting COfrom exhaust gas into a solvent stream selective for absorbing COand creating a rich solvent stream. A solvent regenerator converts a first fraction of the rich solvent stream into a lean solvent stream and a crude COvapor. A cross exchanger exchanges heat between lean and rich solvent streams. Several heat exchangers are associated with the solvent regenerator to transfer heat from multiple distinct waste heat sources into a second fraction of the rich solvent stream as well as recover waste heat from the multiple distinct waste heat sources. A compressor converts the crude COvapor into a concentrated pressurized COproduct, and a COstorage tank receives and stores the COproduct.
