“…Table 4 presents it's corresponding mass composition in percentage: The vapour liquid equilibrium of the respective carbonator process blocks is complex due to the present of ionic species in aqueous phase. Trona decomposition and the carbonation of sodium bicarbonate is associated with a range of equilibrium reactions and can lead to the formation of unwanted mono-and ployhydrate salts [22]. The sequence of N a 2 CO 3 carbonation to form N aHCO 3 is described by:…”

“…Similarly, it is pointed out that the competitive performance of novel carbon capture technology must be assessed both from an ecological and thermodynamic viewpoint. With previous work [22] focusing on the cost analysis of the capture scheme proposed, an investigation of the energy penalty associated with the usage of sodium carbonate looping cycles has not been carried out to date. In this context, this paper explores the potential to further improve the technology's performance on utilising…”

“…Allowing the N a 2 CO 3 sorbent utilised in the process to deplete due to sulphurous species present in the inlet flue gas stream, a range of additional reactions must be accounted for. Over a series of elementary steps outlined in [22] and [30], absorption of gaseous SO x into aqueous N a 2 CO 3 /N aHCO 3 solution results in the formation of sulphurous and sulphuric acid. As reference power plant flue gas composition data available only tabulates SO 2 volume fractions, it will be assumed that the reaction of N a 2 CO 3 and SO 2 under the presence of oxygen according to…”

In the pursuit of shifting technology towards sustainable, environmentally benign processes, post-combustion carbon capture technology is recognised to be a timely mitigation option. This paper presents the development of a novel sodium carbonate-based post combustion carbon capture process utilising the carbonate mineral trona (trisodium hydrogendicarbonate dihydrate) as main sorbent feedstock source. The energy penalty, the fraction of energy sacrificed to capture CO 2 relative to the net energy produced serves as main performance indicator. Investigations on the correlative relationship between energy penalty as a function of capture efficiency are carried out by retrofitting the process to a 600 M W reference coal-fired power plant. The energy penalty of the global system features a distinct local minimum of 3.99 %, corresponding to a CO 2 capture efficiency of 90.00 % and a CO 2 outlet purity of 99.90%. The Specific Primary Energy Consumption for CO 2 Avoided (SPECCA) index corresponding to this minimum is evaluated to be SPECCA = 0.514 M J kg CO −1 2 . Sensitivity analyses on the effect of increasingly high SO 2 flue gas volume fractions y SO 2 show that the capture efficiency is virtually unimpaired for calcination temperatures of 190 ≤ T ≤ 280 • C and y SO 2 ranging from 0.50 to 0.70 %. Whilst commercially available CO 2 capture technology is energy intense and prone to sorbent degradation, the process developed retains high capture efficiencies of calcium oxide-based looping cycles at low operating temperatures and eliminates the predisposition of amine-based sorbents utilised in scrubbing capture schemes to deplete due to the presence of SO 2 in the inlet flue gas stream. It can be concluded that sodium carbonate based post-combustion capture processes are a competitive alternative to existing CO 2 capture technologies.

CO₂—H₂O Capture and Cyclability on Sodium Cobaltate at Low Temperatures (30–80 °C): Experimental and Theoretical Analysis

Sodium cobaltate (NaCoO2) is analyzed for the CO2 cyclic carbonation–decarbonation process at low temperatures (30–80 °C) with relative humidity (RH) values between 0% and 80%, using water vapor as a catalytic intermediate. The presence of H2O clearly enhances the CO2 capture at T < 100 °C, compared with dry conditions, where the amount of CO2 captured increases as a function of RH. These improvements are attributed to the formation of NaHCO3 and Na2CO3 during carbonation. In the case of NaHCO3, water vapor becomes a part of carbonation, favoring reactivity. After the carbonation analysis, the decarbonation process is analyzed using a N2 flow, where results evidence that only NaHCO3 decomposition takes place at low temperatures, producing NaOH and CO2. This result indicates that NaCoO2 can be partially regenerated, suggesting a possible CO2 cyclic carbonation. CO2 carbonation–decarbonation tests are performed, confirming the cyclic capacity and stability. Moreover, the NaCoO2 sample is modified by adding different transition metals (Fe, Cu, and Ni) to improve CO2—H2O sorption under similar physicochemical conditions. Results indicate that Fe‐containing samples present the best properties. Finally, the effect of CO2 partial pressure on NaCoO2 and Fe‐containing samples is analyzed using similar RHs.
