Help needed. Psa-co adsorbent reduction problem
Thread Content
Why is it necessary to strictly control the flow rate of the reducing gas during the critical reduction period when CuCl is reduced to CUC2L? Does the flow rate of Cu(OH)2, H2, CuCl·nH2O, and CuCl2·H2O affect the reduction of the adsorbent? (I know that excessive flow rate can result in incomplete reduction of the adsorbent, but why?)
Molecular sieves have their specific range of applicable conditions. The process parameters for activated molecular sieves also need to be set based on the actual operating conditions. Controlling the flow rate improves the activation efficiency of the molecular sieve itself; however, an increase in flow rate may lead to an increase in gas velocity, which could cause disturbance within the molecular sieve in the purifier and result in damage due to friction between them. Additionally, excessive flow rate is also a form of loss, or it can lead to a reduction in other gas usage amounts. Therefore, it must be controlled in accordance with the original design conditions. For reference.
