Patent number: 9279313Abstract: 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.Type: GrantFiled: December 15, 2014Date of Patent: March 8, 2016Assignee: TOKYO GAS CO., LTD.Inventors: Hiromichi Kameyama, Susumu Nishio, Ziqiu Xue, Toshifumi Matsuoka

Patent number: 8998532Abstract: 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.Type: GrantFiled: March 26, 2012Date of Patent: April 7, 2015Assignee: Tokyo Gas Co., Ltd.Inventors: Ziqiu Xue, Susumu Nishio, Hiromichi Kameyama, Koji Yoshizaki

Patent number: 8684085Abstract: A filter (13) is provided at a tip portion of an injection well (9). A pumping apparatus (5) pumps carbon dioxide stored in a carbon dioxide tank (3). The pumping apparatus (5) feeds carbon dioxide from the carbon dioxide tank (3) into the injection well (9) by means of a pump. In the pumping apparatus, the pressure and temperature of carbon dioxide are maintained at respective predetermined levels or higher by means of a pressure regulation valve, a temperature regulator, etc., whereby carbon dioxide enters a supercritical state. The carbon dioxide having entered a supercritical state is fed in the direction of arrow A through the injection well (9), passes through the filter (13) provided at an end portion of the injection well (9), and is injected into a brine aquifer (11). Carbon dioxide injected into the brine aquifer (11) assumes the form of microbubbles.Type: GrantFiled: August 12, 2009Date of Patent: April 1, 2014Assignee: Tokyo Gas Co., Ltd.Inventors: Hiromichi Kameyama, Susumu Nishio, Ziqiu Xue, Toshifumi Matsuoka
