PROBLEM TO BE SOLVED: To obtain a high-temperature/high-pressure fluid treatment testing apparatus capable of being manufactured at a low cost, having a simple structure without a risk of inclusion of foreign matter, not requiring utilities except electricity, not requiring a special measure against overheating, capable of producing a high-temperature high-pressure fluid and allowing a check of a phenomenon of the high-temperature/high-pressure fluid treatment, and allowing arbitrary addition of a solid or liquid substance other than carbon dioxide and simple treatment of a discharged fluid.;SOLUTION: The high-temperature/high-pressure fluid treatment testing apparatus is composed of a carbon dioxide supplying unit, an high-temperature/high-pressure fluid treatment unit to which carbon dioxide is supplied from the carbon dioxide supplying unit via a connecting tube, a heat exchanger installed at the connecting tube and having an upstream valve and a downstream valve, and a switch of cold brine and hot brine for serving to produce a high-temperature/high-pressure fluid with the temperature-controlled hot brine after cooling the carbon dioxide supplied to the heat exchanger with the temperature-controlled cold brine.;COPYRIGHT: (C)2009,JPO&INPIT
