Waste Heat Utilization for CO2 Capture in the Cement Industry

Udara S. P. R. Arachchige, Dinesh Kawan, Lars-André Tokheim, and Morten C. Melaaen
Abstract—The focus of this work is utilization of waste heat in a cement kiln flue gas in an amine-based CO2 absorption process. The high temperature flue gas from the cement kiln is used to generate steam in a waste heat boiler. The steam is then used to replace some of the steam required in the stripping section of the CO2 capture plant. The required surface area for heat exchange, the cost of installing this area and the payback time of the installation is calculated. The flue gas capture model was developed using the Aspen Plus simulation software. The available excess heat in the cement manufacturing process is calculated to 18 MW for the base case considered. The heat transfer area is calculated as 3115m2. The total cost of the heat exchanger was $ 3.9 million, and the payback time is about 1 year, demonstrating the economic feasibility of applying heat integration when implementing an amine-based CO2 capture process in a cement kiln system.

Index Terms—Carbon dioxide capture, waste heat boiler, flue gas, MEA, cement industry.
