  • Patent number: 8895763
    Abstract: An integrated process for preparing alkylene oxides and alkylene glycols is described. For this purpose, an alkylene oxide plant and an alkylene glycol plant are combined with one another and the water originating from the alkylene oxide plant and also other constituents of the reaction mixture are introduced into the alkylene glycol plant. In this way, alkylene glycols which have been produced in the alkylene oxide plant can be recovered as materials of value and the water circulation into the alkylene glycol plant can be eliminated or drastically reduced. In addition, the energy-intensive treatment of the process water from the alkylene oxide plant can be dispensed with. The integration of the two processes leads overall to better energy efficiency and conservation of resources in the work-up of residues from the process.
