To use fossil fuels (including coal), CO2 capture and storage is a visible option. But large energy requirement for this process and risk associated with storage of CO2 demand alternative solutions including recycling of captured CO2. In this paper, a co-production of power and urea is proposed using coal with captured CO2. Detailed ASPEN Plus® model is developed for this plant. As shift reaction for producing H2 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 CO2 utilization for 95% shift conversion. An economy factor is also defined to estimate the economic advantage of utilizing captured CO2. Results show that economic advantage is obtained for CO2 utilization beyond ~5% for 95% water gas shift reaction and it is beyond ~10% for a 90% shift reaction.
