<p>PROBLEM TO BE SOLVED: To previously avoid an inconvenience wherein a gas having a water content of a tolerable value or over is sucked into a compressor by a method wherein a device equipped with a water content remove and the compressor, a sensor for detecting a water content concentration in a gas is provided to an inlet or outlet of a gas of the water content remover. SOLUTION: When an operating switch of a compressor is closed, a controller opens firstly opening and closing valves 10, 12, and the compressor and a cooling fan are excited thereafter. Then, a natural gas to be fed from a town gas pipe line flows into a hermetically sealed container 3 via a gas pipe line 11, and after a water content in the natural gas is adsorbed by a water adsorbent, the natural gas is sucked by the compressor via a gas pipe line 11B. In this case, a water content in the natural gas flowing in the gas pipe lines 11A, 11B is detected by water content sensors S1, S2, and those detected values are inputted to the controller. Then, in the case where the content detected by the water content sensor S1 exceeds a dehumidifying capacity limit of a water content remover 1, the compressor is stopped.</p> |
