ABSTRACT:
An improved aromatization apparatus is disclosed in which conversion is increased by recycling a highly purified C.sub.2 -C.sub.4 aliphatic stream. Loss of valuable ethane to fuel gas is substantially eliminated. In a preferred embodiment, a dephlegmator purifies the C.sub.2 -C.sub.4 recycle stream.
