methods of heating a reactor feed in a multirreator hydrocarbon dehydrogenation process, and systems for heating a reactor feed in a multirreator hydrocarbon dehydrogenation process

摘要

The present invention relates to methods and systems for heating a reactor feed in a multirreator hydrocarbon dehydrogenation process. The methods and systems are advantageously employed for the production of styrene by catalytic dehydrogenation of ethylbenzene. the catalytic dehydrogenation process employs heating steam which operates at a steam to oil ratio of about 1.0 or less and the relatively low oven temperature of the steam superheater, so that all components exposed to steam in the process outside powered heaters) can be constructed with standard metallurgy.
