“…The concentration of CO 2 in the gas stream, the pressure of the gas stream and the fuel type (solid or gas) are important factors in properly selecting the capture system, based on the specific process and the related engineering aspects [14]. Although the IGCC technology perfectly matches pre-combustion CO 2 capture [15], post combustion CO 2 capture solutions are worth of investigation, as reported by the authors [16,17] and by other researchers [18,19]. Indeed, post-combustion CO 2 capture is a feasible solution in the short term, as amine gas treating is a mature technology, with the alternative option of an ammonia-based process.…”

Due to the complex atmosphere of the entrained flow gasifier, it is difficult to obtain reactivity properties of coal char particles under high-temperature conditions by experiment. The computational fluid dynamics simulation method is a key way to simulate the reactivity of coal char particles. In this article, the gasification characteristics of double coal char particles under H 2 O/ O 2 /CO 2 atmosphere are studied. The results show that the particle distance (L) has an influence on the reaction with particles. With the gradual increase of L, the temperature first rises and then falls among the double particles due to the migration of the reaction area, and the characteristics of double coal char particles gradually approach that of single coal char particles. The particle size also has an influence on the gasification characteristics of coal char particles. As the particle size varies from 0.1 to 1 mm, the reaction area of particles becomes smaller at high temperature and finally attaches to the surface of the particles. The reaction rate and carbon consumption rate increase with increasing particle size. As the size of double particles is changed, the reaction rate trend of double coal char particles at the same particle distance is basically the same, but the change degree of reaction rate is different. With the increase of the distance between coal char particles, the change of the carbon consumption rate is larger for the small particle size.

“…Using exergy analysis, practical solutions for reducing energy loss and enhancing system efficiency can be proposed. There are several examples of exergy studies in the literature that deal with CO 2 capture through chemical and/or physical absorption; − however, only a limited number of them focus on exergy evaluation of the AGR unit. This is due to various theoretical complexities involved in the multicomponent modeling and simulation of AGR at high pressure and temperature conditions.…”

Acid gas absorption using amine solution is a common method for large-scale acid gas separation, although this separation technique suffers from high energy requirements. In this study, the amine-based acid gas removal (AGR) unit aims for operation enhancement. The new amine mixture, a combination of MDEA-DEA-PZ, is used to remove acid gas components from natural gas. As energy consumption is of high importance for both the industry and community, a systematic exergoeconomic optimization and a sensitivity analysis are performed to avoid production loss and enhance the AGR unit's energy efficiency. An exergy assessment is performed to determine the irreversibility and exergy efficiency of the AGR equipment. The stripper and absorber columns show the largest exergy destruction, that is 8.48 and 7.93 MW, respectively; almost 80% of the entire exergy destruction belongs to the stripper and absorber. The exergoeconomic parameters, such as relative cost difference, exergoeconomic factor, and most importantly, the exergy destruction cost, are determined for the key equipment of the AGR unit. The stripper accounts for the largest exergy destruction cost (0.5260 $/s), followed by the absorber (0.2950 $/s). The Taguchi approach is employed to conduct a proper sensitivity analysis and to determine the optimal operation state with the lowest total exergy destruction cost. Five key parameters, including stripper pressure, lean amine loading, lean amine temperature, lean amine concentration, and PZ concentration, are selected for the optimization phase. It is concluded that the stripper pressure and lean amine loading (with 28 and 25% relative significance, respectively) are the key factors with the largest shares in the total exergy destruction value. The optimal operation state obtained by the Taguchi method shows a remarkable reduction in the exergy destruction cost (19.32%) and steam consumption (23.88%). According to the environmental assessment, CO 2 emissions mitigate from 118.88 to 90.49 t/d while operating the process at the optimal conditions. In addition, the carbon tax is reduced to almost 23% at the optimal condition, and the steam cost declines from 3.77 × 10 6 to 2.87 × 10 6 USD/year. This study further highlights the importance of exergoeconomic assessment as a useful strategy for determining the irreversibility costs in energy and chemical sectors.
