  • Publication number: 20160082386
    Abstract: In a carbon dioxide separation and capture apparatus according to an embodiment, a control device calculates a flow rate range of a carbon dioxide gas based on the concentration of the carbon dioxide gas and an output range of a blower. The control device determines a flow rate of the carbon dioxide gas in which the sum of energy is the least based on relationships, corresponding to a preset target amount of carbon dioxide gas to be captured, between a flow rate of the carbon dioxide gas, and sum of energy obtained by summing the amount of heat to be supplied by a heating medium from the external, power of the blower and power of a pump. The control device controls output of the blower, an opening degree of the first flow rate control valve, and an opening degree of the second flow rate control valve.

  • Publication number: 20160068359
    Abstract: A sheet processing device includes a conveying unit, a presser, an end detector, and a setting unit. The conveying unit conveys a sheet having a crease formed therein. The presser presses the crease in the sheet. The end detector detects an end in a conveying direction of the sheet at a position upstream of the presser in the conveying direction. The setting unit sets a crease position where the crease is to be formed. Upon detection of the end in the conveying direction, the conveying unit conveys the sheet to a position where the crease faces the presser, on the basis of the crease position set by the setting unit. The presser presses the crease in the conveyed sheet.
