摘要:
A CO2 reducing system (10A) is constituted by a low-temperature CO2 reducing apparatus (11-1) that includes a low-temperature absorber (1006-1) that reduces at least one of CO2 and H2S by bringing flue gas (1002) including at least one of CO2 and H2S into contact with a low-temperature absorbing solution (1005-1), a low-temperature regenerator (1008-1) that regenerates a low-temperature rich solution (1007-1), a low-temperature rich-solution supply line (12-1) that feeds the low-temperature rich solution (1007-1) to the low-temperature regenerator (1008-1), and a low-temperature lean-solution supply line (13-1) that feeds a low-temperature lean solution (1009-1) to the low-temperature absorber (1006-1) from the low-temperature regenerator (1008-1); and a high-temperature CO2 reducing apparatus (11-2) that is arranged on a side at which the flue gas (1002) is discharged, and that has the same configuration as the low-temperature CO2 reducing apparatus (11-1).
摘要:
An absorbent according to the present invention absorbs CO2 or H2S contained in flue gas emitted from a power generating plant such as a thermal plant, and contains three or more amine compounds selected from linear or cyclic amine compounds having a primary amino group, and linear or cyclic amine compounds having a secondary amino group. By way of a synergetic effect of the mixture of these compounds, the absorption speed of CO2 or H2S absorption is improved. A small amount of CO2 contained in a large amount of boiler flue gas can be absorbed efficiently.

摘要:
An absorbent liquid according to the present invention is an absorbent liquid for absorbing CO2 or H2S or both from gas, in which the absorbent liquid includes an alkanolamine as a first compound component, and a second component including a nitrogen-containing compound having in a molecule thereof two members or more selected from a primary nitrogen, a secondary nitrogen, and a tertiary nitrogen or a nitrogen-containing compound having in a molecule thereof all of primary, secondary, and tertiary nitrogens. The absorbent liquid has an excellent absorption capacity performance and an excellent absorption reaction heat performance, as compared to an aqueous solution containing solely an alkanolamine and a nitrogen-containing compound in the same concentration in terms of wt %, and can recover CO2 or H2S or both from gas with smaller energy.

摘要:
A brake system that provides a good pedal feel, that assists stepping force of a driver by a small motor, and that can control braking force of wheels individually. The brake system comprises a first actuator (5) for increasing a liquid pressure in a master cylinder (2) by driving torque of a motor (51), and a second actuator (6) capable of driving a brake generating mechanism (3) without transmitting power to the master cylinder (2), wherein the actuators (5, 6) to be driven are switched depending on the operation of a brake pedal (1). The first and second actuators (5, 6) are connected to hydraulic piping (4f, 4r), and a pressurized oil is supplied to the brake generating mechanism (3) through hydraulic valve means (63f, 63r, . . . 65rr).
