Abstract
The present invention relates to a method for processing a waste high-pressure fluid, which is yielded by bringing a high-pressure fluid into contact with a processing object in a high-pressure processing vessel to make unnecessary materials on the processing object accompany it. In accordance with the present invention, a novel processing method is provided which includes the steps of draining liquid ingredients, which is obtained from a preliminarily refined waste medium-pressure fluid, having been decompressed from the waste high-pressure fluid and provided to a separating means filled with packing materials, out of a system with unnecessary materials, and refining gas ingredients, which is also obtained from the preliminarily refined waste medium-pressure fluid, in an adsorbing means including adsorbents.
