PROCESS FLOW DIAGRAM OF XYLENE
ANALYSIS AND OPTIMIZATION OF by A Thesis Presented to
Major source of p-xylene and other aromatics, BTX, these days is catalytic. reforming of naphtha and to some extent by products of steam cracking of naphtha . But these methods produce a dilute mixture of p-xylene with other unimportant isomers, m-xylene and o-xylene, along with ethyl benzene (EB) .
Terephthalic Acid Manufacture Technology - Free Library
Technology Description. The process described here is a conventional technology for purified terephthalic acid (PTA) production from p-xylene, similar to one originally developed by Amoco Corp. (merged with BP in 1998) in the 1960s. The figure below presents a simplified flow diagram of the process. P-xylene is mixed with acetic acid solvent[PDF]

Locating and Estimating Sources of Xylene - US EPA
Xylene is an aromatic hydrocarbon that occurs naturally in petroleum and coal tar and is a constituent of smoke from most combustion sources. In the U.S., xylene is produced primarily using catalytic reforming of petroleum (approximately 95%). There were 20 production facilities for mixed xylenes [PDF]

BTX (chemistry) - Wikipedia
Mar 19, 2012In the petroleum refining and petrochemical industries, the initialism BTX refers to mixtures of benzene, toluene, and the three xylene isomers, all of which are aromatic hydrocarbons. The xylene isomers are distinguished by the designations ortho – (or o –), meta – (or m –), and para – (or p –) as indicated in the adjacent diagram.
