“…Among the technologies developed, the postcombustion calcium looping (CaL) system is one of the most promising due to the economic benefits it offers and experience acquired with similar systems already operating at industrial scale [2][3][4][5][6][7]). One of the main advantages of these emerging CaL technologies is the low cost of the sorbent since natural limestone is used as the preferred source of CaO.…”

Furthermore it is demonstrated that the number of calcination carbonation cycles changes the sulphation patterns of the CaO from heterogeneous to homogeneous in all the limestones tested. For 50 carbonation calcination cycles and for particle sizes below 200 µm, the sulphation pattern is in all cases homogeneous. The sulphation rates were found to be first order with respect to SO 2 , and zero with respect to CO 2 . Steam was observed to have a positive effect only in the diffusion through the product layer controlled regime, as it leads to an improvement in the sulfation rates and effectiveness of the sorbent. Most of the experimental results of sulfation of highly cycled sorbents under all conditions can be fitted by means of the Random Pore Model (RPM) assuming that the kinetics and diffusion through the product layer of the CaSO 4 are the controlling regimes.

“…The retrofitted steam cycle which includes an air separation unit (ASU) and integrated CO 2 conditioning unit with interstage cooling increases the net generated power from 1052 MWe to 1533 MWe, resulting in an overall electric efficiency of 39.2% (Hawthorne et al, 2009). One kind of possible integrations of a power plant with CaO-based CO 2 capture process has been studied by Romeo et al (2008).…”

“…1 The main operating conditions of the existing power plant are shown in Table 2 with the typical composition of flue gas and coal composition referred to that in the literature (Romeo et al, 2008). The typical widely used 600MW reheated steam cycle system in recent power industry has been shown in Fig.…”

“…An example process is shown in Figure 8. Calcium looping processes (CLP) take a different approach to CO 2 capture in which CO 2 is directly reacted with calcium oxide [47][48][49] or calcium hydroxide [50] to produce solid calcium carbonate, which can be separated easily from flue gas. The calcium oxide is regenerated in a calcination reactor by reaction with high-purity oxygen and recycled for more CO 2 capture.…”

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

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.
