A natural gas pretreatment system includes: a carbon dioxide removal unit configured to remove carbon dioxide from the natural gas by bringing an absorption liquid and the natural gas into contact with each other; and a water removal unit configured to remove water by causing the natural gas to flow through a packed bed containing a water adsorbent. The packed bed contains a carbon dioxide adsorbent for adsorbing and removing the carbon dioxide that has not been completely removed in the carbon dioxide removal unit, and a concentration of the carbon dioxide contained in the natural gas is measured by an outlet-side carbon dioxide measurement unit on an outlet side of the water removal unit.

A heat exchanging unit is provided that includes a closed vessel separated into first and second compartments by a vertical partition plate thereby leaving a passage above the vertical partition plate. The first compartment has a cooling medium inlet pipe connected thereto, and a through pipe, through which a fluid to be cooled is passed. The through pipe is arranged to pass through the first compartment and includes a heat exchange member placed at a location lower than the top of the vertical partition plate. The second compartment is provided with a demister, and a cooling medium gas outlet pipe connected to the demister. A cooling medium liquid outlet pipe is connected to the second compartment. The heat exchanging unit is preferably used as part of a combined heat exchanging apparatus formed by combining the heat exchanging unit with a mist processing unit, or as part of a multistage heat exchanging apparatus formed by integrating two or more of the heat exchanging units.
