Patent number: 10988427Abstract: An olefin and methanol co-production plant for co-production of an olefin and methanol from a source gas containing methane includes: an olefin production unit for producing the olefin; and a methanol production unit for producing methanol from a carbon oxide gas in the olefin production unit. The olefin production unit includes a partial oxidative coupling device for producing the olefin by partial oxidative coupling reaction of methane contained in the source gas. The methanol production unit includes a reforming device for producing hydrogen by reforming reaction of methane, and a methanol production device for producing methanol by reaction with hydrogen produced by the reforming device. At least one of the reforming device or the methanol production device is configured to perform reaction using the carbon oxide gas in the olefin production unit.Type: GrantFiled: December 14, 2017Date of Patent: April 27, 2021Assignee: Mitsubishi Heavy Industries Engineering, Ltd.Inventors: Shinya Tachibana, Akiyori Hagimoto
