摘要

Three gas separation technologies

chemical absorption

membrane separation and pressure swing adsorption

are usually applied for CO

capture from flue gas in coal-fired power plants.In this work

the costs of the three technologies are analyzed and compared.The cost for chemical absorption is mainly from

$30 to $60 per ton(based on CO

avoided)

while the minimum value is $10 per ton(based on CO

avoided).As for membrane separation and pressure swing adsorption

the costs are $50 to $78 and $40 to $63 per ton(based on CO

avoided)

respectively.Measures are proposed to reduce the cost of the three technologies.For CO

capture and storage process

the CO

recovery and purity should be greater than 90%.Based on the cost

recovery

and purity

it seems that chemical absorption is currently the most cost-effective technology for CO

capture from flue gas from power plants.However

membrane gas separation is the most promising alternative approach in the future

provided that membrane performance is further improved.
