Beschreibungen/Notizen

• A design procedure for oxygenation of water using commercial oxygen in counter-current flow packed columns with simultaneous desorption of dissolved nitrogen is presented. The sensitivity of the process to the design variables is discussed, and, with the aid of a cost model, a rationale for optimizing the process is described. The relatively high cost of oxygen dictates that efficient absorption must be realized for a given combination of water loading rate and packing depth. By considering the oxygen utilization efficiency and the cost per pound of oxygen added, optimal design and operating conditions are identified.
