CONTINUOUS TEMPERATURE RAISING METHOD OF NATURAL HIGH CONCENTRATION CARBONATED MINERAL SPRING

摘要

PROBLEM TO BE SOLVED: To provide a continuous temperature raising method to minimize degassing due to vaporization of free carbon dioxide gas in order to obtain high concentration carbonated mineral spring having body temperature or higher by which warming effect as a warm bath can be expected by raising temperature of the natural high concentration carbonated mineral spring.;SOLUTION: A heat exchanger is used for warming the high concentration carbonated mineral spring to minimize degassing due to vaporization of carbon dioxide gas. At that time, temperature of the high concentration carbonated mineral spring is continuously raised by flowing the carbonated mineral spring and warming fluid such as hot water in a counter-flow system to make a gradual temperature gradient.;COPYRIGHT: (C)2010,JPO&INPIT
