Efficient Surrogates Construction of Chemical Processes: Case studies on Pressure Swing Adsorption and Gas-to-Liquids [PDF]
, 2021 We propose a workflow for reduction in the time required for data generation during generation of statistical digital twins. This methodology is particularly relevant for real-world engineering problems when data generation is expensive.

Energy Procedia, 2019 Abstract A study was performed for hydrogen purification of multicomponent mixture (N2/CO/CO2/CH4/H2=0.007/0.012/0.17/ 0.021/0.79) by one-column VPSA with AC5-KS. The performance of the one-column VPSA process can be predicted by a heat and mass transfer model with porous media adsorption.

How much can novel solid sorbents reduce the cost of post-combustion CO2 capture? A techno-economic investigation on the cost limits of pressure-vacuum swing adsorption [PDF]
, 2021 This paper focuses on identifying the cost limits of two single-stage pressure-vacuum swing adsorption (PVSA) cycles for post-combustion CO2 capture if the ``ideal\u27\u27 zero-cost adsorbent can be discovered.

Barrier‐Assisted Plasma Doping for Spatially Selective Resistance Engineering in MoS2 Transistors
Advanced Materials, EarlyView.Barrier‐assisted NH3 plasma doping enables damage‐free, spatially selective carrier modulation in monolayer MoS2 transistors. An ultrathin pV3D3/Al2O3 protective‐dielectric stack acts as a chemical filter that allows NHx radicals to reach the MoS2 surface while blocking plasma damage. This process achieves a high electron concentration of 4.3 × 1013 cm−

Angewandte Chemie, EarlyView.Atmospheric water harvesting (AWH) under arid conditions requires desiccants that load water below 30% RH and regenerate below 60°C, a performance regime traditionally limited to physisorbents. Here, we show that the inherent hydrolytic instability of M′FSIX‐25‐M coordination networks enable regeneration‐optimized chemisorbents (ROCs) with projected ...

Preliminary evaluation of vacuum desorption efficiency and the influence of vacuum port configuration in a calf-20 VPSA system for CO2 capture [PDF]
E3S Web of ConferencesVacuum Pressure Swing Adsorption (VPSA) is a promising, energy-efficient technology for post-combustion CO? capture; however, mass-transfer resistance during regeneration often limits its performance. To address this, this study evaluates the CO? capture

Studies of adsorbents and pressure/vacuum swing adsorption for co2 capture
, 2015 The capture of carbon dioxide via Pressure/Vacuum Swing Adsorption (PSA/VPSA) has been examined experimentally and mathematically. The adopted method was a two bed/four step process, known as the Skarstrom Cycle. Pelletised and calcined SBA-15 powder has been modified with a monoamine, a diamine and a triamine and has been tested in a PSA configuration.
