To provide a measuring and assessing method which can be used jointly across regions wherein different commercial frequencies are employed. The measuring and assessing method for the AC corrosion risk of a pipeline wherein the coupon is connected to a metallic pipeline buried in the earth and the AC corrosion risk of the pipeline is assessed on the basis of coupon DC current density and coupon AC current density that are acquired from a measured value of a coupon current, wherein the measuring and assessing method comprises: a step of specifying frequency to specify a source of AC corrosion from a waveform of the measured value of the coupon current; and a step of calculating a coupon current density whereby a pair of coupon DC current density and coupon AC current density is acquired from the measured value of the coupon current in one time unit by defining one cycle of a specified frequency as one time unit.

There are provided a carbon dioxide storage apparatus and a carbon dioxide storage method which, through direct injection of carbon dioxide into an underground brine aquifer, can store carbon dioxide efficiently in the brine aquifer. A filter formed of, for example, grindstone is provided at a tip portion of an injection well. A pumping apparatus pumps carbon dioxide stored in a carbon dioxide tank. The pumping apparatus feeds carbon dioxide from the carbon dioxide tank into the injection well by means of a pump. In the pumping apparatus, carbon dioxide is held within a predetermined pressure range and a predetermined temperature range. Carbon dioxide is fed through the injection well, and is injected into a brine aquifer. Carbon dioxide injected into the brine aquifer assumes the form of microbubbles.

A carbon dioxide tank (3) is connected to a pump device (5). The pump device (5) is joined and connected with an infusion well (9), which is a tubular body. The infusion well (9) extends downward beneath the ground (7) and is provided so as to reach a saltwater aquifer (11). Part of the infusion well (9) forms a horizontal well (10) in a substantially horizontal direction. In other words, the horizontal well (10) is a location in which part of the infusion well (9) is formed in a substantially horizontal direction within a saltwater aquifer (11). The horizontal well (10) is provided with filters (13), which are porous members. For the filters (13), for example, a fired member in which ceramic particles are mixed with a binder that binds those particles can be used. Moreover, if the hole diameter for the filters (13) is small, microbubbles with a smaller diameter can be generated.

A cylindrical steam reformer which has a reforming catalyst disposed in a gap between an inner and outer cylinder. Metal zigzag plate elements and metal planar plate elements are arranged alternately between the cylinders such that one metal planar plate element is positioned at the outer wall surface of the inner cylinder and another metal planar plate element at the inner wall surface of the outer cylinder. The walls of the cylinder and metal plates are brazed to form a honeycomb base material. A reforming catalyst is supported on the surface of the metal planar plate element on the outer wall surface-side of the inner cylinder, on the surface of each metal zigzag plate element, on the surface of each metal planar plate element and on the surface of the metal planar plate element on the inner wall surface-side of the outer cylinder.
