A carbon dioxide recovery system includes an absorption tower, a regeneration tower, a rich liquid line, a lean liquid line, a heat exchange unit, and a warn fluid supply unit. The absorption tower allows a carbon dioxide containing gas containing carbon dioxide to contact an absorption liquid capable of absorbing carbon dioxide and produces a rich liquid corresponding to an absorption liquid having absorbed carbon dioxide of the carbon dioxide containing gas. The regeneration tower heats the rich liquid to discharge carbon dioxide from the rich liquid and produces a lean liquid corresponding to an absorption liquid having discharged carbon dioxide. The rich liquid line guides the rich liquid from the absorption tower to the regeneration tower. The lean liquid line guides the lean liquid from the regeneration tower to the absorption tower. The heat exchange unit exchanges the temperature of the lean liquid flowing through the lean liquid line with the absorption liquid having a temperature different from that of the lean liquid flowing through the lean liquid line. The warm fluid supply unit can supply a warm fluid for warming the heat exchange unit to the heat exchange unit.

Abstract

A method for estimating a flange displacement amount includes determining effective three-dimensional coordinate data at a lower first position of a first supported portion on a surface continuous with a lower flange surface and at an upper first position coincident with the lower first position in a horizontal direction on a surface continuous with an upper flange surface. The effective three-dimensional coordinate data are changed such that the effective three-dimensional coordinate data at the lower first position and the effective three-dimensional coordinate data at the upper first position are coincident with each other. According to a difference between a position in a vertical direction indicated by the effective three-dimensional coordinate data at an upper target position and a position in the vertical direction indicated by the effective three-dimensional coordinate data at a lower target position, displacement amounts of the upper target position and the lower target position are obtained.

Abstract

This threat countermeasure system comprises a calculation device and a communication device. The calculation device is configured so as to determine, on the basis of the threat level of at least one target, a countermeasure position of attack on the target. The countermeasure position represents either a first countermeasure position that is attacked in order to temporarily inhibit the function of the target or a second countermeasure position that is attacked in order to stop the function of the target. A first countermeasure period during which the attack is applied to the first countermeasure position in order to at least temporarily inhibit the function of the target may be shorter than a second countermeasure period during which the attack is applied to the second countermeasure position in order to stop the function of the target.
