Title:

A carbon dioxide collection system and an operating method for the same

Document Type and Number:

Japanese Patent JP5938340

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a carbon dioxide recovery system which suppresses deterioration of an absorption liquid and corrosion of a structural material by removing dissolved oxygen in the absorption liquid, and provide an operation method of the same.SOLUTION: A carbon dioxide recovery system includes: an absorption tower which brings gas containing carbon dioxide and an absorption liquid in contact with each other and discharges the absorption liquid which absorbs the carbon dioxide; and a regeneration tower which makes the carbon dioxide emit from the absorption liquid discharged from the absorption tower and discharges a regeneration tower discharge gas containing the carbon dioxide. The system further includes a regeneration tower condenser which condenses water vapor contained in the regeneration tower discharge gas discharged from the regeneration tower. The system further includes an oxygen removing device which brings the absorption liquid discharged from the absorption tower and the regeneration tower discharge gas discharged from the regeneration tower before supplied to the regeneration tower condenser in contact with each other and deaerates the oxygen dissolved in the absorption liquid by the regeneration tower discharge gas.
