3d simulation of the purification of carbon monoxide with cucl(7.0)/ac by the pressure swing adsorption process

In this work, the separation of carbon monoxide (co) from a synthesized gas (syngas) mixture was modeled. it was considered a copper-based adsorbent consisting of cuprous chloride (cucl) on an activated carbon (ac) support (cucl/ac) in a pressure swing adsorption (psa) process. first, the adsorption of syngas components on the cucl/ac adsorbent at 303.15 k was simulated to determine the required data. next, the psa process of separating co from syngas using the cucl/ac absorbent at ambient temperature and pressure of 1000 kpa was evaluated by the computational fluid dynamics simulation. the simulation results showed that with an adsorption bed of 2 m in height and 1 m in diameter, co with appropriate purity (~ 99.5 %) was separated from syngas by cucl/ac. in addition, reducing the inlet feed pressure, or in other words, its velocity or flow can increase the efficiency of the operation (e.g., with a shorter bed height of 0.5 m, a co purity of more than 99.8 % can be achieved at 700 kpa, but with a significant increase in the operating cost).
