Compact carbon dioxide capture and liquefaction system using high-temperature district heating water waste heat from urban power plant combustion exhaust gas

Abstract

A compact carbon dioxide capture and liquefaction system using high-temperature district heating water waste heat from urban power plant combustion exhaust gas may include: a heat storage tank supplied with and storing district heating water heated in a combined heat and power plant; an absorption chiller that recovers waste heat by exchanging heat with the district heating water supplied to the heat storage tank and then supplies the district heating water to the heat storage tank; a first cooler into which exhaust gas discharged from the combined heat and power plant flows and in which heat is exchanged between the exhaust gas and the cooling water supplied from the absorption chiller; and a capture device into which the exhaust gas discharged from the first cooler flows and which captures carbon dioxide contained in the exhaust gas; and a liquefaction device which liquefies the carbon dioxide captured in the capture device.
