Abstract

A tecno-economic investigation into coupling two CO2 capture technologies, post-combustion MEA scrubbing and oxycombustion, to a cement plant under different scenarios was undertaken. The results show that with the assumptions made that oxy-combustion could be a promising technology. However, it has a considerable higher degree of coupling with the cement plant than post-combustion technologies. Due to this higher degree of uncertainty in retrofitting oxy-combustion to an existing cement plant it is believed that this technology is not applicable in the near future. Still, gradual modification of the cement plant during major revamps could reduce the risks, cost, and speed of implementation. The two major elements of oxy-combustion are electricity consumption and the complexity of modifications to the cement plant. A sensitivity analysis was performed were the cost of these two elements were doubled. For MEA scrubbing one of the major cost drivers is the steam consumption. The benefit of utilizing waste heat recovered from the cement plant is considerable. In addition, an effort was made to include the origin of CO2 for the cement plant fuel, electricity consumed, and onsite steam generation. To identify the actual fossil CO2 capture rate and the cost implication this has on the scenarios investigated.
