Other than CO2 capture and storage technology, research for CO2 utilization is also crucial. Among the candidate compounds of CO2 conversion, dimethyl carbonate (DMC) is one of the most promising materials since it has a variety of usages. Converting CO2 to other components is often challenging because of its stable chemical property. However, in this work, processes with intensified configuration were proposed to enhance the economic feasibility. A conventional process and three intensified processes were developed and optimized in Aspen Plus. Economic and environmental evaluations were conducted by calculating the total annual cost (TAC) and the CO2 net emission amount. The results indicated that processes using ethylene oxide (EO) as the dehydrating agent and an intensified configuration including a column with a side reactor (RDSR-HI and RDSRT processes) could save up to more than 88% TAC compared to the conventional process. Moreover, these design configurations had strong potentiality of becoming green processes because the CO2 emission amount due to the energy consumption in the processes was less than the CO2 amount being consumed as feedstock. These two intensified processes provided us a great prospect of converting CO2 to valuable components. Copyright © 2019 American Chemical Society. |
