Process Economics Program Report 182
Published: Jun-87
This report addresses aromatics production from petroleum sources. Catalytic reformate and pyrolysis gasoline are thus the two main feedstocks. Our concern is the major aromatics--benzene, toluene, mixed xylenes, ortho-xylene and para-xylene.
Aromatics technology is relatively mature. Current and forseeable future overcapacity has discouraged innovation, and has also created a highly competitive market environment. At the same time the gasoline pool relies on aromatics as the main contributor to octane number--this situation being accentuated by the trend towards unleaded gasoline.
In view of the above we concentrate on existing technology
and process economics for recovery of the major aromatics. As well as assessing
individual process units, we also examine in some depth the economics of aromatics
complexes, including the Impact of the gasoline market on aromatics pricing.
