PURIFIED WATER FOR WATER ACCOMPANIED WITH WATER SOLUBLE NATURAL GAS, METHOD OF PURIFYING THE SAME, SYSTEM OF PURIFYING THE SAME AND APPLICATION OF THE SAME
PROBLEM TO BE SOLVED: To provide purified water highly utilizing water accompanied with water soluble natural gas, which may fully have the function of natural components dissolved in the accompanied water, to provide a method of purifying the same, to provide a system of purifying the same, and to develop new applications of the water accompanied with the water soluble natural gas that is expected to be applied to broader industrial applications thereof.SOLUTION: Purified water of water accompanied with a water soluble natural gas that can be used for advanced applications is provided by separating a water soluble natural gas sampled from the underground into a natural gas and its accompanied water, and purifying the accompanied water. Suspended solid removal treatment, water softening treatment, adsorption filtration treatment with activated carbon, salt control treatment, iodine compound control treatment are performed as purifying treatments. Additionally, there can be provided various kinds of purified water that can be used for advanced applications.【課題】 水溶性天然ガス付随水の高度利用を可能とする精製水に関し、該付随水に含まれる天然成分の作用を十分に発揮できる精製水及びその精製方法及びその精製システムを提供すること、また、広い産業用途が期待されている水溶性天然ガス付随水の新たな用途開発を課題とする。【解決手段】 地中より採取された水溶性天然ガスより、天然ガスとその付随水とに分離し、この付随水を精製処理して、高度利用可能な水溶性天然ガス付随水の精製水を提供しようとするものであり、精製処理としては、懸濁物質除去処理、軟水化処理、活性炭による吸着濾過処理、塩分調整処理、ヨード分調整処理を行うものである。また、これらの精製により高度利用に対応した各種の精製水を提供することが可能となる。【選択図】図１
