“…The cryogenic unit produces high-pressure liquid CO 2 ready for sequestration, while the membrane step selectively recycles CO 2 to enhance the CO 2 capture rate. Membrane-cryogenic hybrid processes have been practiced for liquid propylene recovery from purge gas streams containing propylene and N 2 [2,60], and they have also been explored for CO 2 capture from coal-fired power plant flue gas containing mainly CO 2 and N 2 [43,47,[61][62][63]. Flows and compositions of the gas streams in a PSA tail gas treatment system process.…”

Syngas processing often requires separation of CO 2 and hydrogen for hydrogen production, and the resulting CO 2-enriched stream presents an opportunity for simultaneous CO 2 capture. For example, syngas-based integrated gasification combined cycle (IGCC) power plants are envisioned as an efficient means of producing power from coal where CO 2 capture technologies can be applied relatively easily. Membrane technology is an attractive approach for CO 2 capture because of inherent process advantages such as simplicity, reliability, compactness and modularity. This paper (Part II of a two-part study) performs techno-economic analysis for CO 2-selective membranes in three hydrogen production or utilization applications: methane reformer/pressure swing adsorption processes, oxygen-blown coal-fired IGCC power plants using GE gasification technology, and air-blown coal-fired IGCC power plants using Transport Integrated Gasification (TRIG) technology. These processes require membranes with CO 2 /H 2 selectivities of 10-20, which can be provided using Polaris TM membranes. Hybrid approaches using a combination of membrane and cryogenic processes are evaluated for the production of high-pressure liquid CO 2 ready for utilization or sequestration. The optimal membrane CO 2 /H 2 selectivity and influence of CO 2 capture rate on the cost of CO 2 capture are determined, providing general guidelines for future membrane development. The cost of CO 2 capture with these membrane processes depends not only on the feed CO 2 partial pressure, but on the feed CO 2 concentration as well.

“…Their results indicated that the energy requirement for CO 2 capture process is much lower than for the conventional process. The same idea was implemented by Hasse et al . in which they used an Air Liquide membrane based on subambient temperature operation of a hollow fiber membrane combined with cryogenic unit.…”

Post‐combustion CO₂ capture with chemical absorption and hybrid system: current status and challenges

et al. 2018

Post-combustion CO 2 capture from the power and industrial sectors has gained widespread attention due to its ability to retrofit easily with newly installed and existing plants. This state-of-the-art, updated review provides an overview of technical issues in post-combustion CO 2 capture related to process performance, energy requirements for CO 2 capture, and inconsistencies in the prediction of CO 2 capture cost. Recent updates are presented regarding chemical absorption-desorption systems, and particularly CO 2 absorption and solubility enhancement studies, absorber operation at elevated pressure, recent developments in absorber configuration, and methods for reducing the heat duty of strippers. Furthermore, recently developed post-combustion hybrid techniques such as the membrane-absorbent hybrid process, the membrane-cryogenic hybrid process, the membrane-adsorption hybrid process, the absorption-electrolysis hybrid process, and the solar thermal electrochemical process (STEP) are discussed. Finally, we suggest areas for improvement and indicate that there are significant future prospects for post-combustion CO 2 capture. C

“…Inspired by the work of Hasse et al and others, who proposed a sub-ambient membrane process that required considerable pretreatment, the work discussed here primarily focuses on the holistic design of the subambient CO 2 capture process for any separation process that relies on pressure driving forces (in particular, membranes and pressure swing adsorption [PSA]). [25][26][27][28][29] As little discussion has been had concerning the opportunities for PSA processes to fit within this scheme, this work also explores the potential of simple PSA processes for subambient CO 2 capture using a number of case studies based on different adsorbent materials.…”

Adsorption of CO 2 from post-combustion flue gas is one of the leading candidates for globally impactful carbon capture systems. This work focused on understanding the opportunities and limitations of sub-ambient CO 2 capture processes utilizing a multistage separation process. A hybrid process design using a combination of pressure-driven separation of CO 2 from flue gas (e.g., adsorption-or membrane-based separation) followed by CO 2 -rich product liquefaction to produce high-purity (>99%) CO 2 at pipeline conditions is considered. The operating pressure of the separation unit is a key cost parameter and also an important process variable that regulates the available heat removal necessary to reach the sub-ambient operating conditions. The economic viability of applying pressure swing adsorption (PSA) processes using fiber sorbent contactors with internal heat management was found to be most influenced by the productivity of the adsorption system, with productivities as high as 0.015 mol CO 2 /kg sorb À1 sec À1 being required to reduce costs of capture below $60/ ton CO 2 captured. This analysis was carried out using a simplified two-bed process, and thus there is opportunity for further cost reduction with exploration of more complex cycle designs. Three exemplar fiber sorbents (MIL-101(Cr), UiO-66, and zeolite 13X) were considered for application in the sub-ambient process of PSA unit.Among the considered sorbents, zeolite 13X fiber composites were found to perform better at ambient temperatures as compared to sub-ambient. MIL-101(Cr) and UiO-66 fiber composites had improved purity, recovery, and productivity at colder temperatures reducing costs of capture as low as $61/ton CO 2 . Future economic improvement could be achieved by reducing the required operating pressure of the PSA unit and pushing the Pareto frontier closer to the final pipeline requirement via a combination of PSA cycle design and material selection.
