Fremgangsmåde til udledningsvarmeudnyttelse i forbindelse med en carbondioxidudvindingsproces

摘要

An exhaust heat utilization method for a carbon dioxide recovery process comprises heating returning hot water by at least one heat exchange selected from heat exchange with the regenerated absorbing liquid after heat exchange, heat exchange with carbon dioxide exhausted from the regeneration tower, and heat exchange with saturated water after heating the bottom of the regeneration tower, thereby obtaining hot water.
