摘要：

In a chemical plant 100 including a carbon dioxide recovery unit 10 and a urea plant 11, the carbon dioxide recovery unit 10 treats combustion exhaust gas from a boiler B to separate and recover carbon dioxide. Low-pressure steam 33 generated in the urea plant 11 is supplied to the carbon dioxide recovery unit 10 as a heat source for its regeneration tower reboiler. Carbon dioxide 22 recovered in the carbon dioxide recovery unit 10 is sent to an EOR facility, a storage facility, and the like outside the plant. Thus, the low-pressure steam generated in the urea plant 11 is effectively used as a heat source for the carbon dioxide recovery unit 10.
