Patents by Inventor Yuudai Katou

Yuudai Katou has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11119092
    Abstract: In the present invention, an input unit receives input of production conditions relating to a plurality of parameters relating to production of a biogas in a biogas production facility. An index value corresponds to an amount of heat per unit quantity of a biogas generated by the biogas production facility under the production conditions. A condition classifying unit classifies the production conditions on the basis of the plurality of parameters and the index value. An output unit outputs information relating to the result of classification by the condition classifying unit.
    Type: Grant
    Filed: February 20, 2019
    Date of Patent: September 14, 2021
    Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.

  • Patent number: 9840675
    Abstract: The system is provided with: a first heat exchanger which is interposed at an intersection between a rich solution supply line and a lean solution supply line, which has absorbed CO2 and H2S extracted from a bottom portion of an absorber, and a regenerated absorbent; a second heat exchanger which is interposed at an intersection between a semi-rich solution supply line and a branch line branched at the branch portion C from the lean solution supply line, and the lean solution; a merging portion which merges a branch line configured to supply the lean solution after heat exchange with the lean solution supply line; and a flow rate adjusting valve which is interposed in the lean solution supply line to adjust the distribution amount of the lean solution.

  • Patent number: 9777232
    Abstract: The system includes: an absorber which brings an introduction gas into contact with an absorbent that absorbs CO2 and H2S; an absorbent regenerator which releases CO2 or the like to regenerate the absorbent; a second supply line which returns a regenerated absorbent to the absorber from the regenerator; a third supply line which extracts a semi-rich solution from the vicinity of a middle stage of the absorber, and introduces the semi-rich solution to the vicinity of the middle stage of the regenerator; and a semi-rich solution heat exchanger which is interposed at an intersection between the third supply line and the second supply line to perform the heat exchange between the semi-rich solution and the lean solution.
