“…Short residence times would allow in practice the use of a commercial circulating fluidized bed (CFB) reactor for the carbonator operated at high gas velocities (of a few meters per second). CFB reactors provide optimum heat and mass transfer and are commonly employed in industrial applications to enhance gas–solid reactions. − Carbonator models based on CFBs are being widely studied in recent years for the application of the CaL process to capture CO 2 as depending on the multicycle CaO conversion and carbonation kinetics. In this regard, an interesting subject for further work would be to adapt these models to the particular behavior of the sorbents for CaL-CSP conditions to obtain relevant parameters for optimum performance such as the solids residence time.…”

Deep penetration of renewable energies into the grid relies on the development of large-scale energy storage technologies using cheap, abundant and non-toxic materials. Concentrated Solar Power (CSP) is particularly suitable to massively store thermal energy for dispatchable electricity generation. This is currently accomplished in a few demonstration plants by using molten salts albeit in a not competitive way yet. Process simulation studies indicate that thermochemical energy storage of CSP by means of the Calcium Looping (CaL) technology would reduce the cost of storage and increase the flexibility of energy supply provided that widely available and cheap CaO precursors with high and stable multicycle activity are used. In this work, we investigate the behavior of Calcium rich steel slag at CaL conditions that would expectedly maximize the efficiency of CSP energy storage and power production. When treated with acetic acid, this non-toxic widely abundant waste yields a CaO rich solid with stable conversion near 0.8 over successive carbonation/calcination cycles at these CaL conditions.

“…Therefore, the application of another type of solid–gas contactor, such as fluidized bed or moving bed may help overcome such limitations. The choice of any of the previous alternatives can be confusing since the type of reactor does not seem to depend directly on the sorption mechanism or the type of adsorbent, as suggested by Kim et al Their investigation also concluded that both fluidized and moving beds could be a less expensive option as compared to amine absorption and that the moving bed could be even more cost-effective if there is heat integration during the regeneration of the adsorbent. Consequently, the moving bed temperature swing adsorption process (MBTSA) is being regarded as a potential technology to reduce the cost of energy demand in large-scale CO 2 capture by means of intelligent heat integration, which is not easy to achieve with circulating fluidized bed or bubbling processes .…”

We simulate a moving bed temperature swing adsorption (MBTSA) process to capture CO2 in postcombustion context using zeolite 13X as adsorbent. Experimental adsorption isotherms for CO2 and N2 were performed gravimetrically to obtain the equilibrium input data for the model. The need of the flue gas drying was demonstrated by pure water and binary water/CO2 experimental adsorption isotherms, and the energy penalty of the water removal was accounted for within the energetic duty of the unit. The model consists of three sections (adsorption, regeneration, and cooling) each with its own model and integrated by a composite model that simulates the entire unit. Given the large number of variables and parameters in a MBTSA process, which can be arranged in different input data sets, a parametric study of the effect of several variables (feed gas flow rate, regeneration temperature, adsorbent residence time in the adsorption section, feed temperature, solid loading) on the key performance parameters of the process was performed. The results showed that, under the studied conditions, values up to 99% and 91% mol of CO2 recovery and purity could be achieved, respectively. The specific energy consumption, which included an energy recovery in the cooling section, was found to be competitive against reported values for commercial amine absorption separation processes suggesting that the MBTSA process might be a potential separation process candidate for large-scale postcombustion CO2 capture by adsorption.

“…Also researchers from Kawasaki in Japan published results from a CO2 capture test for moving-bed system, however, lacking information about the process details and adsorbent used [7]. Kim and coworkers showed by modelling how the energy demand of the process can be significantly reduced by heat exchange between the hot adsorbent leaving the desorber with the cold adsorbent entering the desorber [8,9]. We have recently shown that reduced energy penalty compared to state-of-art amine based capture can be achieved when using the MBTSA process in a post-combustion NGCC context [10].…”

Effect of Gas Recycling on the Performance of a Moving Bed Temperature-Swing (MBTSA) Process for CO2 Capture in a Coal Fired Power Plant Context

A mathematical model of a continuous moving-bed temperature-swing adsorption (MBTSA) process for post-combustion CO 2 capture in a coal-fired power plant context has been developed. Process simulations have been done using single component isotherms and measured gas diffusion parameters of an activated carbon adsorbent. While a simple process configuration with no gas re-circulation gives quite low capture rate and CO 2 purity, 86% and 65%, respectively, more advanced process configurations where some of the captured gas is recirculated to the incoming flue gas drastically increase both the capture rate and CO 2 purity, the best configuration reaching capture rate of 86% and CO 2 purity of 98%. Further improvements can be achieved by using adsorbents with higher CO 2 /N 2 selectivity and/or higher temperature of the regeneration section.
