Strategic Insights

— 1 min read

A carbon dioxide recovery-type power generating system has been patented by Hitachi, Ltd., marking a significant innovation in power generation technology. The patented system, disclosed by the World Intellectual Property Organization (WIPO), comprehensively addresses environmental concerns by effectively reducing emissions and recovering carbon dioxide. The invention is the result of collaborative efforts by the inventors, including Hisayuki Orita, Masaaki Mukaide, Nobuyuki Hokari, Tsuyoshi Shibata, and Hiroki Sato.

Key Takeaways:

  • The patented system is a carbon dioxide recovery-type power generating system that integrates various components to minimize emissions and maximize energy recovery.
  • The system consists of a boiler, NOx removal device, heat exchanger, precipitator, desulfurization equipment, and a regenerative-type carbon dioxide recovery and desorption device.
  • The regenerative-type carbon-dioxide absorption and desorption device is a critical component that removes absorbed carbon dioxide by ventilating combustion exhaust gas and a portion of air heated at the heat exchanger as desorbed gas.
  • The system is designed to recover carbon dioxide from combustion exhaust gas while minimizing environmental impact.
  • The inventors, Hisayuki Orita, Masaaki Mukaide, Nobuyuki Hokari, Tsuyoshi Shibata, and Hiroki Sato, developed the system as part of a comprehensive solution to power generation technology's environmental challenges.

Statistics:

  • The system was patented under Publication No. WO/2011/111116 and filed under Application No. PCT/JP2010/001782 on March 12, 2010.
  • The regenerative-type carbon-dioxide absorption and desorption device is a key component in the patented system, designed to recover carbon dioxide from combustion exhaust gas.
  • The system comprises a total of 6 disparate components, each contributing to the effective recovery of energy and reduction of environmental impact.
