Abstract: In the preparation of ethylene oxide by direct oxidation of ethylene with air or oxygen using water as heat carrier to dissipate the heat of reaction, with water vapor being formed, a process for optimizing the specific energy consumption is proposed. In this, the water vapor is first expanded in one or more backpressure steam turbine(s) T for operating working machines M, before it is fed to one or more consumers, such as bottoms reboilers or steam injectors, for further utilization.

Abstract: The invention relates to a method for optimizing the specific energy consumption of a method for producing ethylene oxide by direct oxidization of ethylene with air or oxygen, using water as the heat transfer medium for removing the heat of the reaction so that water vapor is formed. According to the invention, the water vapor is first expanded in one or several back pressure steam turbine(s) T for operating machines M before being supplied for use by one or several other consumers, such as bottom evaporators or steam injectors.

Abstract: A process for the distillative recovery of high purity monoethylene glycol from the hydrolysis, product of ethylene oxide by pressure dewatering, preferably in a battery, vacuum dewatering and subsequent purifying distillation, wherein during the vacuum dewatering an aqueous stream is withdrawn which contains-monoethylene glycol in a concentration below 1% by weight, preferably below 0.1% by weight, medium boilers and low boilers. The withdrawn aqueous stream is, optionally after further workup, removed from the system.
