“…Wetting occurs when the liquid solution enters the pores of the membrane and has been shown to increase the resistance to mass transfer [13,21,22]. Several researchers have reported that amine solutions can wet PP membranes [23][24][25][26]. Although no wetting experiments were conducted as part of this work, it is plausible that wetting occurred.…”

“…This was explored in more detail by Wang et al [24], who attributed the wetting to a chemical interaction between the PP membrane and DEA solution that changed the initial morphology of the membrane. Studies by Matsumoto et al [25] and Nishikawa et al [26] tested PP, polyethylene (PE) and polytetrafluoroethylene (PTFE) membranes with aqueous monoethanolamine (MEA) solutions. The PTFE membranes were the only membranes that resisted wetting after several hours of operation.…”

Reversible chemisorption of carbon dioxide: simultaneous production of fuel-cell grade H2 and compressed CO2 from synthesis gas

et al. 2007

One vision of clean energy for the future is to produce hydrogen from coal in an ultra-clean plant. The conventional route consists of reacting the coal gasification product (after removal of trace impurities) with steam in a water gas shift (WGS) reactor to convert CO to CO 2 and H 2 , followed by purification of the effluent gas in a pressure swing adsorption (PSA) unit to produce a high purity hydrogen product. PSA processes can also be designed to produce a CO 2 by-product at ambient pressure. This work proposes a novel concept called "Thermal Swing Sorption Enhanced Reaction (TSSER)" which simultaneously carries out the WGS reaction and the removal of CO 2 from the reaction zone by using a CO 2 chemisorbent in a single unit operation. The concept directly produces a fuel-cell grade H 2 and compressed CO 2 as a by-product gas. Removal of CO 2 from the reaction zone circumvents the equilibrium limitations of the reversible WGS reaction and enhances its forward rate of reaction. Recently measured sorption-desorption characteristics of two novel, reversible CO 2 chemisorbents (K 2 CO 3 promoted hydrotalcite and Na 2 O promoted alumina) are reviewed and the simulated performance of the proposed TSSER concept using the promoted hydrotalcite as the chemisorbent is reported.

“…The separation mechanism is essentially absorption. The gas flows through one side of the membrane while a CO 2 selective solvent like an amine solution flows through the other side 4, 32, 33. The CO 2 ‐laden solvent leaving the membrane is thermally regenerated in a separate unit to produce the high purity CO 2 gas.…”

in Wiley InterScience (www.interscience.wiley.com).A synopsis of the published literature on removal of CO 2 from a flue gas is given. A novel thermal swing chemisorption (TSC) process concept is proposed for removal and recovery of compressed CO 2 from a flue gas without precompression, predrying, or precooling. The process uses Na 2 O promoted alumina as a reversible CO 2 selective chemisorbent in conjunction with the principles of rapid thermal swing adsorption for direct production of compressed CO 2 from a flue gas. Several complementary process steps are used in the design to compress the product CO 2 and to achieve high CO 2 recovery and sorbent capacity utilization. Judicious steam purge steps are used for highly efficient sorbent regeneration and to minimize the steam requirement. The CO 2 chemisorption characteristics of the sorbent are reviewed and a model simulation of the TSC process performance is reported.
