“…Consequently, the proposed system has the potential to improve upon both the stand-alone MR and AR systems currently in place as well as the traditional WGSR design. This work is a continuation of our previous work, 33 which focused on a techno-economic analysis (TEA) of an MR IGCC plant. The remaining article is structured as follows: the proposed novel MR-AR IGCC plant is first presented, and the MR-AR system utilized in the design is described in detail, including the governing equations utilized in the MR-AR models.…”

In this work, the novel concept of a combined membrane−adsorptive reactor sequence (MR-AR) is developed and implemented in an integrated gasification combined cycle (IGCC) plant. This novel MR-AR IGCC plant is subsequently analyzed from an economic viewpoint through a techno-economic analysis (TEA) of the proposed plant. This novel design can achieve over 90% carbon capture without the use of a dual-stage Selexol unit. The resultant intensified design is more efficient from both an economic and power production perspective than the traditional IGCC plants with precombustion carbon capture and storage (CCS) technology. The COMSOL software package is utilized to simulate the MR-AR sequence proposed in this work, and UNISIM software (Honeywell) is used to create an intensified process flowsheet of the proposed MR-AR IGCC plant, which is subsequently heat-integrated. The TEA developed for the MR-AR IGCC power plant will be used to identify the extent of process intensification the proposed design has over the traditional IGCC plants with precombustion CCS. The results demonstrate a reduction in both the cost-of-electricity (COE) and in the capital cost of the proposed design over the baseline case.

“…These approaches draw the hydrogen away from the reaction zone and thus shift the equilibrium further towards a mixture of CO2 and H2, increasing the conversions that can be achieved. A recent article by Pichardo et al [63] suggests that the incorporation of these membrane reactors into a standard coal Integrated Gasification Combined Cycle (IGCC) operation with CCS produces 2.2% more power, with lower capital cost. However, operating costs increase significantly, primarily due to the cost of replacement membranes.…”

Carbon capture and storage has declined in prominence as a large scale response to climate change, but carbon dioxide capture will remain important into the future for the hydrogen economy, for steel and cement, as well as chemical production. Membrane technology can be a significant component of this industry if cost competitive. While most scientific research is focussed on developing novel materials for this application, it is the process design of the membrane operations that is much more critical in reducing these costs. In post combustion capture, this involves optimisation of the pressure driving force across the membrane, either through feed compression or permeate vacuum pumping, integration of downstream cryogenic purification and the use of combustion air sweeps. In pre-combustion capture, integration of the membrane into the water gas shift reactor is key. Membrane contactors can also play a role, but must be carefully engineered to ensure pressure drop control and to minimise capillary condensation of water.

“…The separation of the CO 2 from such stream is a better obtained, from a thermodynamic and energy intensity standpoint, compared to post combustion treatment. As such applications deals with high temperature and high pressure streams, identifying materials capable of achieving high separation under extreme conditions is highly required 9,10 .…”

The capture of CO2 under high pressure and temperature is challenging and is required in a number for industrial applications including natural gas processing. In this work, we examine the use of benchmark hybrid ultraporous materials HUMs for their potential use in CO2 adsorption processes under high-pressure conditions, with three varying temperatures (283, 298 and 318 K). NbOFFOVE-1-Ni and SIFSIX-3-Ni were the selected HUMs given their established superior CO2 capacity under low pressure (0–1 bar). Both are microporous with highly ordered crystalline structures as compared to the mesoporous hexagonal silica (Santa Barbara Anhydrous-15 (SBA-15)). SBA-15 was previously tested for both low and high-pressure applications and can serve as a benchmark in this study. Sorbent characterization using XRD, SEM, FTIR and N2 adsorption were conducted to assure the purity and structure of the sorbents. TGA analysis were conducted to establish the thermal stability of the sorbents under various temperatures. High-pressure CO2 adsorption was conducted from 0–35 bar using magnetic suspension balance (Rubotherm). Although the SBA-15 had the highest surface (527 m3/g) are of the three adsorbents, the CO2 adsorption capacity (0.42 mmol/g) was an order of magnitude less than the studies HUMs with SIFSIX-3-Ni having 2.6 mmol/g, NbOFFIVE-1-Ni achieving 2.5 mmol/g at 298 K. Multistage adsorption isotherms were obtained at different pressures. In addition, results indicate that electrostatics in HUMs are most effective at improving isosteric heat of adsorption Qst and CO2 uptake. Higher temperatures had negative effect on adsorption capacity for the HUMs and SBA-15 at pressures between 7–9 bar. In SAB-15 the effect of temperature is reversed in what is known as a cross over phenomena.
