“…However, they showed that optimisation of the process parameters can reduce the net efficiency penalty to between 8.5% and 9.5% points, depending on the CAP configuration used. A similar integration impact was also obtained by Valenti et al [40] (8.6% points); however, the CAP model in their study was composed of flash drums connected in series and, thus they have not accounted for the mass and heat transfer in the packing. Since neither of these studies involved the rate-based modelling approach for the absorption and regeneration processes in the CAP plant, nor analysed the enhancements for process integration, the aim of this paper is to evaluate the alternative CFPP retrofit scenarios using a high-fidelity process model of a CFPP and a rate-based CAP plant.…”

“…This result is in line with the modeling prediction. These recent studies show that the aqueous ammonia based CO 2 capture process requires much less heat for the solvent regeneration than MEA based capture processes (Jo¨nsson and Telikapalli, 2012;Jilvero et al, 2012;Valenti et al, 2012;Darde et al, 2012).…”

-Aqueous Ammonia (NH 3 ) Based Post Combustion CO 2 Capture: A Review -Aqueous ammonia (NH 3 ) is an emerging, promising and challenging solvent for capture of CO 2 emitted from coal and gas fired power stations and other industrial sources. Over the last few years, intensive research activities have been carried out to understand the thermo-chemical and physical properties of the CO 2 -NH 3 -H 2 O system and the chemistry/kinetics involved, to obtain information on absorption rate, ammonia loss, regeneration energies, and practical issues, and to assess the technical and economical feasibility of the aqueous ammonia based post combustion capture technologies. This paper reviews these research activities, makes comparisons with MonoEthanolAmine (MEA, the benchmark solvent) and identifies the research opportunities for further improvements.

“…Although the process is similar in structure to amine-based processes, in the ammonia-based process, aqueous ammonia reacts with CO2 in the flue gas in an absorption tower at atmospheric pressure and low temperatures (either at room temperature [12] or at chilled temperatures of 0-20 °C [13,14]) to form ammonium bicarbonate salts. The flue gas is exhausted after a washing step, and the ammonia bicarbonate slurry leaving the bottom of the absorber is sent to a regenerator at higher temperatures (100 °C) and pressures (20-40 bar) [14] in which the CO2 is desorbed and released as a high pressure gas.…”

Comparison of CO2 Capture Approaches for Fossil-Based Power Generation: Review and Meta-Study

et al. 2017

This work is a meta-study of CO 2 capture processes for coal and natural gas power generation, including technologies such as post-combustion solvent-based carbon capture, the integrated gasification combined cycle process, oxyfuel combustion, membrane-based carbon capture processes, and solid oxide fuel cells. A literature survey of recent techno-economic studies was conducted, compiling relevant data on costs, efficiencies, and other performance metrics. The data were then converted in a consistent fashion to a common standard (such as a consistent net power output, country of construction, currency, base year of operation, and captured CO 2 pressure) such that a meaningful and direct comparison of technologies can be made. The processes were compared against a standard status quo power plant without carbon capture to compute metrics such as cost of CO 2 emissions avoided to identify the most promising designs and technologies to use for CO 2 emissions abatement.
