(2) Four packing material configurations with heights of 60 cm full, 45 cm full, 30 cm split, and 30 cm full. (3) Inlet water temperatures to the humidifier of 70 ˚C, 60 ˚C, and 50 ˚C. (4) Inlet water flow rates to the humidifier of 6 kg/min, 4 kg/min, and 2 kg/min. (5) Cooling water flow rates of 16 kg/min and 8 kg/min. 6) Air cycle type; the closed and open air cycle types. The optimal values were attained under the following operational conditions; using cellulose kraft paper type, a configuration height of 60 cm, an inlet seawater temperature of 70 ˚C, an inlet seawater flow rate of 6 kg/min, a cooling water flow rate of 16 kg/min, and a closed air cycle. The resulting values were 1.4 L/20 min for fresh water productivity, 0.63 for GOR, 1.2 for RR, $ 0.0076/L for fresh water cost, and efficiencies of 0.99 and 0.84 for the humidifier and dehumidifier, respectively.
