1. A method of producing a cooled dry gas, the method comprising:
bubbling an input gas through an aqueous saline solution having a temperature of 20 to 80 degree Celsius (° C.) to produce a first intermediate gas;
bubbling the first intermediate gas through freshwater having a temperature of greater than −5° C. to less than 20° C. to produce a second intermediate gas;
cooling the second intermediate gas to a temperature of −40 to −5° C. to produce a cooled gas; and
passing the cooled gas through a chemical adsorbent to produce a saturated adsorbent and the cooled dry gas.
