  • Patent number: 9901862
    Abstract: A carbon dioxide recovery system includes an absorption tower in which carbon dioxide is absorbed into an absorbing solution then the absorbing solution is output to a regeneration tower in which carbon dioxide is released from the absorbing solution. The regeneration tower outputs the absorbing solution from which carbon dioxide has been released and an exhaust gas included released carbon dioxide and water vapor. In a condensing section the exhaust gas is separated into dioxide gas stream and a condensed water stream. In a mixing section the condensed water is mixed with an amine to a replenishment amine aqueous solution in which the amine is dissolved in the condensed water. In a replenishment section the absorbing solution is mixed with the replenishment amine aqueous solution.

  • Publication number: 20170356394
    Abstract: An evaporated fuel treatment device is provided with an electric-operated valve, a positive-pressure relief valve mechanism and a negative-pressure relief valve mechanism. The electric-operated valve has a valve body for opening/closing a vapor passage allowing a fuel tank and a canister, and adjusts the flow rate by electrical control. The positive-pressure relief valve mechanism opens when the pressure at the fuel tank side has a value greater than or equal to a predetermined positive pressure value. The negative-pressure relief valve mechanism opens when the pressure at the fuel tank side has a value less than or equal to a predetermined negative pressure value. The electric-operated valve is configured such that the valve body is moved in the valve opening direction by the pressure at the fuel tank side that is higher, by a predetermined value, than the valve opening pressure for the positive-pressure relief valve mechanism.
