Process And System For Producing A Product Hydrocarbon

Abstract: The invention relates to a process for producing a product hydrocarbon, in which a charge hydrocarbon in a charge mixture containing the charge hydrocarbon and oxygen is subjected to selective oxidation in order to obtain a product mixture containing the product hydrocarbon and water, the charge hydrocarbon being ethane, the product hydrocarbon being ethylene, and the selective oxidation being carried out in the form of oxidative dehydrogenation of ethane, and in which a subsequent mixture is formed by separating at least some of the water from at least some of the product mixture. Here, the oxygen contained in the charge mixture is partially converted during the selective oxidation process, such that the product mixture has a first residual oxygen content and the subsequent mixture has a second residual oxygen content. The first and/or the second residual oxygen content is detected using at least one first measurement device. At least one second measurement device is provided at the end of the catalyst bed and is used to detect a variable that characterises operational stability, the variable that characterises the operational stability being a temperature at the end of the catalyst bed. Using a process-control and/or evaluation unit, measurement data of the at least one first measurement device and/or the at least one second measurement device are detected over a detection period and are evaluated and/or processed so as to obtain subsequent data, and process control is carried out on the basis of the subsequent data, the reactor used for the selective oxidation being cooled using at least one coolant and the at least one operating parameter being or including a coolant temperature of the at least one coolant, and/or the at least one operating parameter being or including an oxygen content of the charge mixture. The present invention also relates to a corresponding system.
