Patent number: 9416683Abstract: According to one embodiment, a carbon-dioxide-recovery-type steam power generation system comprises a boiler that produces steam and generates an exhaust gas, a first turbine that is rotationally driven by the steam, an absorption tower allows carbon dioxide contained in the exhaust gas to be absorbed into an absorption liquid, a regeneration tower that discharges the carbon dioxide gas from the absorption liquid supplied from the absorption tower, a condenser that removes moisture from the carbon dioxide gas, discharged from the regeneration tower, by condensing the carbon dioxide gas using cooling water, a compressor that compresses the carbon dioxide gas from which the moisture is removed by the condenser, and a second turbine that drives the compressor. The steam produced by the cooling water recovering the heat from the carbon dioxide gas in the condenser is supplied to the first turbine or the second turbine.Type: GrantFiled: March 28, 2014Date of Patent: August 16, 2016Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Yuya Murakami, Nobuo Okita, Takeo Takahashi, Mikio Takayanagi, Takeo Suga, Takeshi Sasanuma, Toshihisa Kiyokuni, Hideo Kitamura

Patent number: 8720203Abstract: According to one embodiment, a carbon-dioxide-recovery-type steam power generation system comprises a boiler that generates steam and an exhaust gas, an absorption tower that allows carbon dioxide contained in the exhaust gas to be absorbed in an absorption liquid, a regeneration tower that regenerates discharges a carbon dioxide gas from the absorption liquid, a reboiler that heats the absorption liquid of the regeneration tower, a turbine that is rotationally driven by the steam, a condenser that generates condensate by cooling steam exhausted from the turbine, a compressor that compresses the carbon dioxide gas, and a cooler that cools the carbon dioxide gas, which has been compressed by the compressor, while using a part of the condensate as cooling water. The reboiler is supplied with steam from the turbine and steam generated by the cooling of the carbon dioxide gas at the cooler.Type: GrantFiled: October 20, 2011Date of Patent: May 13, 2014Assignee: Kabushiki Kaisha ToshibaInventors: Takeshi Sasanuma, Nobuo Okita, Takeo Takahashi, Mikio Takayanagi, Takeo Suga, Yuya Murakami, Toshihisa Kiyokuni, Hideo Kitamura

The first condenser generates condensate by cooling steam exhausted from the turbine. The second condenser condenses the carbon dioxide gas while using a part of the condensate as cooling water, and generates hot water. The desuperheater lowers the temperature of the steam exhausted from the turbine by spraying the hot water, and supplies the steam at lowered temperature to the reboiler.Type: GrantFiled: October 20, 2011Date of Patent: April 29, 2014Assignee: Kabushiki Kaisha ToshibaInventors: Takeshi Sasanuma, Nobuo Okita, Takeo Takahashi, Mikio Takayanagi, Takeo Suga, Yuya Murakami, Toshihisa Kiyokuni, Hideo Kitamura
