“…There are many studies which analyze the effect of operating conditions of CO 2 capture process on power plant efficiency (Abu Zhara, 2011;Cifre, 2009;Goto, 2013;Strube, 2011). However, the relationship between heat and energy duty of CO 2 capture process and compressors on the efficiency of the power plants is not cleared yet.…”

Carbon capture is a promising technology for carbon dioxide (CO 2 ) removal from large stationary CO 2 sources. The effects of carbon dioxide capture process on output efficiency of fossil power plants were investigated. Supercritical pulverized coal and integrated coal gasification combined cycle (IGCC) were assumed as model coal-fired power plants for this investigation. Heat-driven and pressure-driven CO 2 capture processes such as chemical absorption and physical adsorption were assumed for CO 2 capture process. In this study, these technologies were evaluated and compared under the unified basis and conditions by using the commercial process simulator. For IGCC plant, the efficiency penalty by installing water-gas shift reaction was also investigated. Gross and net power generation, efficiency and the efficiency penalty by CO 2 capture process were calculated. Heat duty for CO 2 capture process and CO 2 compression conditions were varied, and those effects on the efficiency penalty were obtained. The results provide a guideline for development of CO 2 capture process of power plants.

“…Process factors that have a large influence on the CO2 purity in pre-combustion capture include the choice of solvent and the CO2 capture process configuration and, in particular, the decision whether to remove sulfur species simultaneously with CO2 (co-capture scenario) or to remove them in a separate stream for possible further processing (separate capture scenario). The potential benefits of co-capturing impurities in pre-combustion gasification systems have been investigated in a report published by the (Goto et al, 2013). Techno-economic studies often aim to find the optimal configuration for the process (Rao and Rubin, 2006;Schach et al, 2011;).…”

A techno-economic assessment of power plants with CO2 capture technologies with a focus on process scenarios that deliver different grades of CO2 product purity is presented.The three leading CO2 capture technologies are considered, namely; oxyfuel combustion, pre-combustion and post-combustion capture. The study uses a combination of process simulation of flue gas cleaning processes, modelling with a power plant cost and performance calculator and literature values of key performance criteria in order to evaluate the performance, cost and CO2 product purity of the considered CO2 capture options. For oxyfuel combustion capture plants, three raw CO2 flue gas processing strategies of compression and dehydration only, double flash system purification and distillation purification are considered. Analysis of pre-combustion capture options is based on integrated gasification combined cycle plants using physical solvent systems for capturing CO2 and sulfur species via three routes; co-capture of sulfur impurities with the CO2 stream using Selexol TM solvent, separate capture of CO2 and sulfur impurities using Dedication: This paper is dedicated to the memory of our friend and colleague, Dr. Robert M. Woolley, who made a significant input to the CO2QUEST project and whose expertise, commitment and great humour will never be forgotten.

“…In industries, the steam is generated by two means. The first one is heating the bulk water by combustion of coals, natural gases or biomass [13,14]. Natural gas is heavily used in Western countries and the Middle East for integrated water and power production [15], which causes the environmental pollution.…”

Efficient solar vapor/steam generation is important for various applications ranging from power generation, cooling, desalination systems to compact and portable devices like drinking water purification and sterilization units. However, conventional solar steam generation techniques usually rely on costly and cumbersome optical concentration systems and have relatively low efficiency due to bulk heating of the entire liquid volume. Recently, by incorporating novel light harvesting receivers, a new class of solar steam generation systems has emerged with high vapor generation efficiency. They are categorized in two research streams: volumetric and floating solar receivers. In this paper, we review the basic principles of these solar receivers, the mechanism involving from light absorption to the vapor generation, and the associated challenges. We also highlight the two routes to produce high temperature steam using optical and thermal concentration. Finally, we propose a scalable approach to efficiently harvest solar energy using a semi-spectrally selective absorber with near-perfect visible light absorption and low thermal emittance. Our proposed approach represents a new development in thermally concentrated solar distillation systems, which is also cost-effective and easy to fabricate for rapid industrial deployment.
