A combined experimental and modeling study was performed to evaluate the relation between sorbent characteristics and process performance for solid sorption postcombustion CO 2 capture. A pulverized coal (PC) and a natural gas combined cycle (NGCC) power plant were considered, addressing CO 2 and H 2 O sorption. The measured isotherms for PEI/silica sorbent were implemented in an equilibrium-based flow sheeting model. The PC regeneration heat demand is 3.9 GJ/ton CO 2 captured. This is lower than that of the NGCC and, though a direct comparison is not valid, similar to a literature MEA case. Solid sorption systems hold the promise to be energetically superior to MEA: a 2-fold increase in CO 2 adsorption capacity (to 4.4 mmol/g) yields a regeneration heat demand of 3.3 GJ/ton, even when accompanied by a similar increase in H 2 O adsorption capacity.

“…Temperature or temperature‐pressure swing processes are the most common techniques applied in the regeneration of the sorbent. Main advantages of the AISS in comparison to aqueous MEA lay on the reduction of energy demand for regeneration due to less evaporation of water, and lower specific heat capacity of the sorbent, which allow to obtain a reduction of overall CO 2 capture costs . The heat required for the CO 2 desorption step in processes making use of AISS is around 1.5 GJ/tCO 2 ,.…”

“…The heat required for the CO 2 desorption step in processes making use of AISS is around 1.5 GJ/tCO 2 ,. Moreover, the use of solid sorbents like pore‐expanded mesoporous silica loaded with MEA or DEA,, avoids those energy losses associated to the partial evaporation of liquid solvent in the stripper required in MEA process ,…”

“…Optimally a system based on these sorbents would be designed as a combination of fluidized bed or moving bed systems, for solid circulation between absorber and stripper. The design of the fluidized‐bed absorption and regeneration reactors for amine impregnated solid sorbents may also results in significant reductions in capital costs, around 21 % reduction compared to MEA…”

Efficiency and Energy Analysis of Power Plants with Amine‐Impregnated Solid Sorbents CO₂ Capture

et al. 2018

Some of the relevant post‐combustion CCS research trends includes the reduction of the energy consumption required for regeneration. It is a priority to find novel solvents that show high affinity for CO2 together with an ease of regeneration and reuse. Recently, impregnated solid sorbents have been suggested to tackle with these issues. In particular amine‐impregnated solid sorbents require less regeneration energy due to the reduction in water content and the higher heat capacity of solids. As a consequence, they may have the ability to reduce the efficiency penalty of CCS in power plants. Several studies have quantified the efficiency penalty of CO2 capture in commercial power plants with amine absorption. It is generally assumed a reduction of 7–10 efficiency points. Nevertheless, there is not a clear quantification of the effect of solid sorbent capture plants on efficiency penalty. This paper tries to shed some light on this issue. The objective of this work is to demonstrate and quantify the effect on net power and efficiency penalty of using amine‐impregnated solid sorbents when applied as an option to carbon capture. A full process integration of the system and an overall optimisation for power generation have been carried out. Interesting results have been achieved; it is possible to reduce the efficiency penalty down to 6.7 efficiency points. This figure could make feasible the impregnated amine solid sorbent as a future and promising option for CO2 capture.

“…Selection of material for CO 2 capture at different environmental and industrial conditions is still a major challenge for the energy generation sector. Large number of materials such as polymers (Du et al 2011), co-polymers (He et al 2014), organic/inorganic materials (Veselovskaya et al 2013), metal organic composites (Seema et al 2014), solids adsorbents (Krutka et al 2013), liquid absorbents (Munoz et al 2009), ionic liquids (Kumar et al 2014) and various nano-composite structures have been investigated to capture CO 2 from the flue gas. Some of the major challenges that require due attention at the material selection stage are; CO 2 capturing efficiency, reproducibility, selectivity (Seema et al 2014), capability (Markewitz et al 2012), stability at various temperature and pressure conditions (Al-Khabbaz et al 2014), multi-purpose applicability ) and economic practicability (Tzimas and Peteves 2005) of the material.…”

Synthesis, characterization and evaluation of porous polybenzimidazole materials for CO2 adsorption at high pressures

et al. 2016

Porous polybenzimidazole polymers have been under investigation for high and low pressure CO 2 adsorption due to the well-built stability under high pressure and at various temperatures. Pressure swing and temperature swing processes like integrated gasification combined cycle require materials which can operate efficiently at high pressure and high temperature and can remove CO 2 . In this manuscript we report synthesis, characterization and evaluation of two polybenzimidazole materials (PBI-1 and PBI-2), which were prepared with two different solvents and different cross-linking agents by condensation techniques. Low and high pressure CO 2 sorption characteristic of both the materials were evaluated at 273 and 298 K. Thermal gravimetric analysis showed high temperature stability up to 500°C for the studied materials. PBI-1 has shown very good performance by adsorbing 3 times more (1.8025 mmolg -1 of CO 2 ) than PBI-2 at 0°C and at low pressures. Despite low surface area results obtained via BET techniques, at 50 bars PBI-1 adsorbed up to 6.08 mmolg -1 of CO 2 . Studied materials have shown flexible behavior under applied pressure that leads to so-called ''gate-opening'' adsorption behavior and it makes these materials promising adsorbents of CO 2 at high pressures and it is discussed in the manuscript in detail.
