چکیده

The design of adsorption systems for separation CO2/N2 in carbon capture applications is notoriously challenging because it requires constrained multiobjective optimization to determine appropriate combinations a moderately large number system operating parameters. status quo the literature use nondominated sorting genetic algorithm II (NSGA-II) solve problem. This approach 1000s time-consuming process simulations find Pareto front problem, meaning can take days computational time obtain solution. As an alternative approach, we have employed Bayesian algorithm, Thompson sampling efficient (TSEMO). For productivity/energy usage optimization, that TSEMO able essentially identical solution problem as found using NSGA-II, while requiring 14 times less time. We used postcombustion 1000 MW coal fired power plant two adsorbent materials, zeolite 13X and ZIF-36-FRL. Although ZIF-36-FRL showed promising process-scale performance previous studies, industrial-scale inferior benchmark 13X, 21% greater cost per tonne CO2 captured. Finally, also tested framework when coupled with data-driven machine learning modeling framework. In this instance, incumbent NSGA-II offers better than by factor 3.

Capture of Co 2 by Vacuum Swing Adsorption Process Using Activated Carbon Beads

Pitch-based AC beads (particle size about 1mm) were synthesized from coal tar pitch through the emulsion method without using binder material in our laboratory. Adsorption equilibrium and adsorption kinetics of CO2 and N2 on the activated carbon beads were studied experimentally and theoretically. Based on the equilibrium and kinetics data, an improved vacuum-pressure swing adsorption (VPSA) pr...

Investigation of carbon dioxide capture from hydrogen using the thermal pressure swing adsorption process: Central composite design modeling

In this study pre-combustion capture of carbon dioxide from hydrogen was performed using a 5A zeolite adsorber. A one column thermal pressure swing adsorption (TPSA) process was studied in the bulk separation of a CO2/H2 mixture (50:50 vol%). The adsorption dynamics of the zeolite bed were investigated by breakthrough experiments to select the suitable range for operational factors in the desig...

Producing Nitrogen via Pressure Swing Adsorption

Nitrogen gas is a staple of the chemical industry. Because it is an inert gas, nitrogen is suitable for a wide range of applications covering various aspects of chemical manufacturing, processing, handling, and shipping. Due to its low reactivity, nitrogen is an excellent blanketing and purging gas that can be used to protect valuable products from harmful contaminants. It also enables the safe...
