    Abstract: The present invention relates to a method for producing ethylene oxide by reacting ethylene with oxygen in the presence of at least one catalyst containing silver, wherein the reaction occurs in a reactor that has a catalyst packing having at least two layers (i) and (ii), and the silver content of the catalyst in the layer (i) is lower than the silver content of the catalyst in the layer (ii). The catalyst packing preferably comprises a further layer (a), with which the reaction mixture comes in contact prior to layers (i) and (ii). According to the invention, the silver content of the catalyst in the layer (a) is higher than the silver content of the catalyst in the layer (i).

    Abstract: A process for heat integration in engineering processes in which, in a heat carrier circuit (10), a heat carrier medium takes up heat from a first process stream (14) in a first heat exchanger (12) and releases it to a refrigeration system (30), in addition, in a refrigerant circuit (20), a refrigerant is cooled in the refrigeration system (30) and the refrigerant takes up heat from a second process stream (24) in a second heat exchanger (22) or a second process stream (24) is cooled in the refrigeration system (30), characterized in that the first process stream (14) is a vapour stream from a thermal separation apparatus, and in that the temperature of the heat carrier medium is increased by heat supply between egress from the first heat exchanger (12) and ingress into the refrigeration system (30).
