Title:
貯留物質の貯留装置および貯留物質の貯留方法
Document Type and Number:
Japanese Patent JP5315346
Kind Code:
B2
Abstract:
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.
