| 1. A waste high-pressure fluid processing method, comprising the steps of:
bringing a high-pressure fluid into contact with a processing object in a high-pressure processing vessel;
decompressing said waste high-pressure fluid accompanied with unnecessary materials on said processing object into a waste
medium-pressure fluid;
refining preliminarily said waste medium-pressure fluid which is provided to a separating means including packing materials;
and
dealing with ingredients obtained through the preliminary refinement, comprising the steps of;
draining liquid ingredients with said unnecessary materials out of a system, and
refining gas ingredients by an adsorbing means including adsorbents,
further comprising the additional step of providing said waste medium-pressure fluid to said separating means once after storing
in a reservoir tank provided upstream said separating means.
