Design of sustainable processes for CO2 capture

Global warming is one of the main environmental problems affecting the world. The continuous emissions of Carbon Dioxide (CO ₂) released into the atmosphere have generated a critical environmental situation worldwide. It is reported that 70% of CO ₂ emissions are related to electricity production. For this reason, if there is an increase in energy demand therefore it is expected to increase CO ₂ emissions. Globally, different alternatives have been sought to reduce the environmental footprint related to CO ₂ emissions, highlighting the implementation of capture and storage plants as a promising alternative. In this work it is presented the multiobjective optimization for the simulation of a CO ₂ capture plant coupled to a power plant considering a stochastic optimization having as objective function the minimization of the environmental implications (Ecoindicator 99), the control properties (Condition Number), as well maximize the economic indicator (Return on investment). The analysis considered the most used fuels in the power plant. From the results, the design with the best overall performance is when natural gas is burned. Presenting the lower environmental impact with 22549.43kEcopoints and a return on investment of 73.24%. This results in a sustainable process with less environmental impact.
