This document provides a comparative study of the retrofitability of different CO2 capture technologies which have been investigated within the framework of the CEMCAP project. Different criteria have been defined for a qualitative assessment of the retrofitability, e.g. the impact on the cement production process, the required equipment and associated footprint, additional utilities and services, the requirement of new chemicals or other substances and the existing operational experiences with the individual capture technology. The assessment of the retrofitability of the individual capture technologies was carried out with a color coding system. Only technical aspects have been taken into account, whereas economic assessments have been carried out in other work packages. The retrofitability of capture technologies is an important issue as the implementation of CCS in the cement sector will predominantly be carried out at existing kiln lines.
