\textcopyright Springer-Verlag Berlin Heidelberg 2015. Coal-based power plants are largest emitter of CO 2 as a single sector. To use fossil fuels (including coal), CO 2 capture and storage is a visible option. But large energy requirement for this process and risk associated with storage of CO 2 demand alternative solutions including recycling of captured CO 2 . In this paper, a co-production of power and urea is proposed using coal with captured CO 2 . Detailed ASPEN Plus\textregistered model is developed for this plant. As shift reaction for producing H 2 has significant effect on output parameters, analysis is done for two different values of shift reaction, i.e., 90 and 95 % conversion. Plant consumes substantial auxiliary power (~19 % for the base case). Auxiliary power becomes a minimum for about 25 % captured CO 2 utilization for 95 % shift conversion. An economy factor is also defined to estimate the economic advantage of utilizing captured CO 2 . Results show that economic advantage is obtained for CO 2 utilization beyond ~5 % for 95 % water gas shift reaction and it is beyond ~10 % for a 90 % shift reaction.
