Carbon capture is a technology that can reduce emissions of greenhouse gases such as carbon dioxide. For carbon dioxide produced in the atmosphere or in other industries, captures and stores carbon dioxide through chemical or physical methods, or processes and utilizes the captured carbon dioxide in other ways, so as to reduce the content of carbon dioxide in the atmosphere. Utilizing the captured carbon dioxide to achieve economic benefits is an efficient and economical method for carbon capture. This article focuses on the analysis of the three fields of petrochemical, construction, and power industry. By using the captured carbon dioxide to generate specific additional energy, and then comparing the benefits of the additional energy, it can be concluded which aspects are developable. Through analysis and comparison, the limitations and prospects for development in the three fields of petrochemical industry, construction industry and power industry can be given. Especially in power industry, the use of carbon capture technology to capture carbon dioxide from exhaust gases and store it underground can reduce emissions by at least 90%. In conclusion, after comparing the three sectors of the petrochemical industry, the building industry and the power industry. It can be concluded that the objectives to be achieved by applying carbon capture technologies and utilising, the additional empowerment generated, are similar. All are aimed at reducing emissions, improving energy efficiency and achieving sustainable development.

Post-Combustion CO2 Capture Using Solid Sorbents: 1 MWe Pilot Evaluation

Carbon dioxide capture from ambient air could compensate for all carbon dioxide emissions to the atmosphere. Such capture would, for example, make it possible to use liquid, carbon-based fuels in cars or airplanes without negatively impacting the climate. We present a specific approach based on a solid sorbent in the form of an anionic exchange resin, that absorbs carbon dioxide when dry and releases it when exposed to moisture. We outline a particular implementation of such a moisture swing and discuss the scale of the collectors, the energy consumption, and the indirect carbon dioxide emissions related to the operation of carbon dioxide capture devices.

Solid sorbents are considered to be promising materials for carbon dioxide capture. In recent years, many studies have focused on the use of solid waste as carbon dioxide sorbents. The use of waste resources as carbon dioxide sorbents not only leads to the development of relatively low-cost materials, but also eliminates waste simultaneously. Different types of waste materials from biomass, industrial waste, household waste, and so forth were used as carbon dioxide sorbents with sufficient carbon dioxide capture capacities. Herein, progress on the development of carbon dioxide sorbents produced from waste materials is reviewed and covers key factors, such as the type of waste, preparation method, further modification method, carbon dioxide sorption performance, and kinetics studies. In addition, a new research direction for further study is proposed. It is hoped that this critical review will not merely sum up the major research directions in this field, but also provide significant suggestions for future work.

Carbon dioxide emissions from the combustion of fossil fuels are a significant factor in global climate change. Large stationary sources such as coal-fired electric generating plants are likely to be the most cost-effective targets for carbon dioxide capture. At present, liquid amine-based scrubbing systems are the only processes available for this application. Processes based on regenerable solids that absorb carbon dioxide from flue gas and release it in concentrated form have the potential to be less expensive to operate. This paper summarises the results of studies conducted at RTI and Louisiana State University (LSU) to investigate the feasibility of using sodium or potassium carbonate as a sorbent. Upon reaction with carbon dioxide and water (also present in flue gas), this material is converted to sodium or potassium bicarbonate. Upon heating (ideally with low grade heat from the generating plant), carbon dioxide and water vapour are released and the solid carbonate can be reused. Work to date has focused on thermogravimetry (TG) and bench scale fluidised-bed testing, as well as characterisation of materials and thermodynamic and kinetic analyses. TG studies with sodium carbonate have indicated that the sorption reaction takes place rapidly at approximately 60°C and that the sorbent can be regenerated at temperatures less than 120°C. A five-cycle test conducted in a bench scale fluid bed reactor system indicated that the sorbent could be regenerated and reused. The process implications of compound salts and hydrates in the sodium carbonate system on the useful capacity of the sorbent and heat removal requirements were also investigated.
