METHOD AND APPARATUS FOR DETECTING CONCENTRATION OF GAS-HYDRATE BY SPECTROSCOPY |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a method and apparatus for detecting a concentration of gas-hydrate accurately and in a short time in a slurry solution or a solid mixture with ice. <P>SOLUTION: The method for detecting a concentration of gas-hydrate includes: measuring OH absorption bands of water in the range of 1.3-2.2μm by near infrared spectroscopy under the same conditions in both ice containing gas-hydrate and ice containing no gas-hydrate; and comparing OH absorption peaks near 1.5μm and 2μm of water molecules of the ice containing gas-hydrate and the ice containing no gas-hydrate. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
