Patent ID: 8652236

Claim:
A method for recovery of high purity carbon dioxide from a gaseous source comprising the steps of: a. feeding a gas (G 1 ) comprising at least carbon dioxide, oxygen, N 2 , and nitrogen oxides, into an absorption column (A 1 ), b. absorbing the gas (G 1 ) in an absorbing agent, by which the gas (G 1 ) is separated into a carbon dioxide-lean gas (G 2 ) and a carbon dioxide-rich liquid (L 1 ), c. pressurising and heating the liquid (L 1 ) obtained in step b in order to provide the liquid (L 2 ), d. separating by flashing in a flash column (A 3 ) the liquid (L 2 ) obtained in step c into a N 2 -, NO x -, and oxygen-rich gas (G 3 ) and a N 2 -, NO x -, and oxygen-depleted liquid leaving the flash column (A 3 ), e. pressurising the liquid leaving the flash column (A 3 ) in step d in order to provide the liquid (L 3 ), f. separating the liquid (L 3 ) obtained in step e into a carbon dioxide-rich stripper off gas and a carbon dioxide-depleted liquid (L 4 ) by stripping in a stripper column (A 2 ), g. cooling the stripper off gas obtained in step f in order to provide a cooled gas (G 4 ).
