Geological carbon dioxide storage system with improved reliability

Abstract

Disclosed is a geological CO2 storage system that allows geological storage and management of CO2 and has excellent reliability. The geological CO2 storage system comprises a geological CO2 storage section for storing CO2 stored in a plurality of storage tanks in a predetermined geologic formation, and a CO2 concentration detector disposed in an unsaturated zone located below a ground surface corresponding to the geologic formation where CO2 is stored detects a concentration of CO2 in the unsaturated zone. The geological CO2 storage section includes a manifold section formed of a plurality of section branches and used for introducing CO2 from a plurality of storage tanks, a distribution chamber communicating with the manifold section and an outlet side connected to an injection pipe extending toward the geologic formation so that the CO2 introduced through the manifold section is supplied to the injection pipe, a temperature regulator for regulating temperature of CO2 introduced into the distribution chamber, and a flux / pressure regulator for regulating a flux and a pressure of the CO2 to be geologically injected through the distribution chamber.

Description

technical field [0001] The present invention relates to a carbon dioxide (CO 2 ) geological storage systems, and in more detail about the ability to stably store CO 2 Geological storage with the ability to effectively monitor CO during and after storage 2 The leakage or not of the CO 2 geological storage system. Background technique [0002] In the global greenhouse effect, which has become a major global environmental problem, CO 2 become the biggest factor. CO 2 Many of them are contained in the exhaust gas emitted by thermal power plants using coal, steel factories using iron ore as raw materials, and petrochemical plants using petroleum as raw materials. Therefore, in order to prevent the global warming chamber effect as much as possible, CO 2 to process. [0003] CO 2 Processing technologies include geological storage technology, ocean storage technology, and mineral carbonation technology. [0004] Among them, ocean storage technology (ocean storage technolog...

Problems solved by technology

This mineral carbonation technology requires a large amount of reaction energy, and the storage and processing of carbonate minerals itself will cause environmental concerns, so it is a technology that has been difficult to realize until now.
