Liquid fuels that can be burned either in boilers or compression ignition engines to generate electricity have been the target products. The CO₂ and H₂O produced from combustion are recirculated back to the synthesis units, thus forming a closed cycle of “renewable energy (unstable energy supply) + CO₂ + H₂O → liquid fuels → electricity (stable supply)”. This novel closed loop energy storage process integrated with a 670 MW supercritical power plant was analyzed using the Aspen Plus software package. Methanol was selected as the targeted liquid fuel through three major synthesis routes: CO + H₂, CO₂ + H₂ and CO₂ + H₂O, in which CO and H₂ came from the electrolysis of CO₂ and H₂O. The performances of the three methanol synthesis routes were thermodynamically analyzed. The results show that the optimal methanol synthesis route is the direct conversion of CO₂ and H₂O through electrocatalysis when CO₂ conversion is above 42%, while when CO₂ conversion is below 42% the best choice turned out to be the CO hydrogenation. The direct conversion of (CO₂ + H₂O) using electrocatalysis method was adopted as the liquid fuel synthesis route for the near-zero-carbon-emission power plant. The overall CO₂ emission from the near-zero-carbon-emission power plant is 44.13 kg/MWh accounting for just 6.45% of the advanced coal fired power plant.]]> Sat 24 Mar 2018 07:40:52 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37960 S), bubble size (L_B) and rising velocity (V_B) in STFRs and their dependence on operating conditions. Under high Reynolds numbers (Re'≥681), many particles are present in the liquid film and significant bubble surface wave disturbance is observed even when the Capillary number is low (Ca'<0.01). Depending on whether bubble surface distorts (BSD) and/or particles travel between slugs (PTS), four STF patterns are identified and mapped against the flow conditions, with pattern I (with no BSD or PTS) and pattern IV (with both BSD and PTS) occurring at low and high fluids velocities, respectively. The STF patterns are independent of solid loading (when <10%v/v) but show dependency on particle size and flow conditions. Both solid loading and particle size marginally affect V_B, yet have a profound impact on L_B and L_S. Empirical correlations for predicting V_B, L_B and L_S in STFRs are developed. The correlation of V_B proves valid for both slurry and standard Taylor flow systems covering 1.2≤Re'≤3551 and 0.0002≤Ca'≤0.39 for a wide range of fluids in both circular and square channels with size of 480µm-3.02mm.]]> Fri 17 Nov 2023 11:43:25 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51804 Fri 14 Jun 2024 10:11:57 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51030 Fri 14 Jun 2024 09:57:53 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55593 Fri 07 Jun 2024 12:09:42 AEST ]]>
