    Abstract: An absorbent for absorbing CO2 or H2S, or both of CO2 and H2S in a gas contains, as components, (a) a secondary linear monoamine, (b) a tertiary linear monoamine, and (c) a secondary cyclic diamine. When the concentration of the secondary linear monoamine (a) is more than 30% by weight and less than 45% by weight and the concentration of the tertiary linear monoamine (b) is more than 15% by weight and less than 30% by weight, absorbability of CO2 or H2S, or both of CO2 and H2S is good, and releasability of CO2 or H2S that have been absorbed during regeneration of the absorbent is good. The amount of steam of a reboiler used during regeneration of the absorbent in a CO2 recovery unit can be thus reduced.

  • Publication number: 20220096996
    Abstract: A composite amine absorbent according to the present invention is an absorbent for absorbing CO2 or H2S, or both of CO2 and H2S in a gas. The absorbent is obtained by dissolving (1) a linear monoamine, (2) a diamine, and (3) propylene glycol alkyl ether, for example, represented by the following chemical formula (I) in water. In the composite amine absorbent, the components complexly interact, and the synergistic effect thereof provides good absorbability of CO2 or H2S, or both of CO2 and H2S and good releasability of CO2 or H2S absorbed during regeneration of the absorbent. Furthermore, the amount of water vapor in a reboiler 26 used during regeneration of the absorbent in a CO2 recovery unit 12 can be reduced.

  • Publication number: 20210387523
    Abstract: A reaction force control system for a pedal that is configured to stably operate a vehicle in which an operating mode can be shifted between normal and one-pedal modes, without requiring a complicated operation, and without disturbing a driver. An operating mode is selected from a one-pedal mode in which a drive force and a brake force are controlled by manipulating an accelerator pedal, and a normal mode in which drive force is controlled by manipulating the accelerator pedal, and the brake force is controlled by manipulating the brake pedal. Reaction force applied to the accelerator pedal is increased for a predetermined period of time when shifting from one of the operating modes to the other one, and thereafter the reaction force is adjusted in accordance with a position of the accelerator pedal in the other one of the operating modes.

  • Patent number: 11165217
    Abstract: A bandpass filter allows a light ray of a predetermined band including a wavelength band of a color of a laser beam, which is a target of detection, among light rays from a subject to pass therethrough. An imaging unit of a video camera captures the light ray passing through the bandpass filter. The controller analyzes a frequency for each brightness level of a video signal generated based on an imaging signal output from the imaging unit and detects a peak at which the frequency protrudes at a specific brightness level. The controller detects a trajectory of a straight light ray in a frame of the video signal. The controller detects that the laser beam is irradiated when the peak exists at a specific brightness level and the trajectory of the light ray exists in the frame.
