Energy-efficient process intensification for post-combustion CO2 capture: A modeling approach

Introductory Chapter: Distillation

“…This last item is closely related to climate change and other negative environmental impacts. But, high-energy consumption remains a challenge [7]. Fortunately, there are different ways of saving energy.…”

“…Recent developments in energy-related research increasingly rely upon simultaneous resource saving and pollution reduction by applying process integration [4]. Process intensification is a feasible way to reduce heat requirement [7]. One of the most common examples of the process intensification field is the reactive distillation, where the integration of reaction and separation is performed.…”

Modification of postcombustion CO2 capture process: A techno‐economic analysis

“…Jin et al . modeled a combination of five different modifications including membrane separation in a single flowsheet and reported a reduction of 28% in regeneration energy 26 . Oh et al .…”

“…25 Jin et al modeled a combination of five different modifications including membrane separation in a single flowsheet and reported a reduction of 28% in regeneration energy. 26 Oh et al developed a superstructure by integrating UNISIM® and MATLAB® to evaluate different process modifications and reduced the energy consumption by 7%. 27 Recently, Oh et al reported the reduction in energy consumption by stripper modification and concluded that increase in capital cost by process modification is inevitable, however, the energy consumption and operating cost can be saved by optimizing the process configurations.…”

PEST study of CO2 capture strategy from 2007 to 2018

“…These methods have been used as a way to try to reduce CO2 emissions in many applications, but using different ways of applying them, such as using ionic liquids to capture and store CO2 in processes based on monoethanolamine in the combustion gases of a power plant, reducing the energy consumed by up to 30% and reducing CO2 emissions [15], as well as using an amine impregnated silicic acid compound as an adsorbent for CO2 capture, obtaining that the desorption activation energy was 335 Kj/mol and the estimated thermal regeneration load for the absorber was 53.29 kJ/mol CO2 [16], [17], as well as for the study of CO2 capture by carbontae loop in a 1 MW plant [18], analyzes the influence of crushing on the CO2 capture yield of CaO derived from natural limestone, for which, depending on the process used to obtain CaO, CaO will have less carbonation and will have greater crystallization or greater carbonation and less crystallinity of Cao, producing more CO2 emissions [19]. Although the method is very useful for reducing emissions, it is characterized by high energy consumption, with which research was conducted to use a hybrid configuration of the CO2 capture process after combustion in thermal power plants using aqueous monoethanolamine as a simulated absorbent in Aspen Plus [20]. The main contribution of this study is to understand and show the evolution of CO2 capture in different countries, analyzing the trend and number of publications during 2007 to 2018 using HistCite.…”
