Abstract: Systems for dehydrogenating an alkane are provided. An exemplary system includes a furnace and further includes alkane heating chambers, regeneration mixture heating chambers, and two groups of reaction chambers, all located within the furnace. The alkane heating chambers and regeneration mixture heating chambers can preheat an alkane feed and a regeneration mixture feed, respectively. The two groups of reaction chambers can be switchably coupled to an alkane feed and a regeneration mixture feed such that an alkane can flow through one group of reaction chambers while a regeneration mixture flows through the other group of reaction chambers. Processes for dehydrogenating an alkane are also provided.

Abstract: The present invention provides, among other things, new processes for separating and purifying C4 fractions from a crude C4 stream. Compared to prior methods, the processes of the present invention simplify the C4 separation processes, afford more possible configurations for separation and purification, and are more cost effective. The processes and systems provided herein can be used as part of a cost-effective and efficient method for synthesizing methyl tertiary-butyl ether.
