Xylene exists as a clear liquid and can be found in three different isomeric forms: orthoxylene (o-xylene), metaxylene
(m-xylene), and paraxylene (p-xylene).
In the now available analysis of the global market for xylene, the market research institute Ceresana provides data concerning individual xylene isomers: for the first time, markets for para-, ortho- and metaxylene split by important countries and regions are analyzed separately in a single study.
Global production of metaxylene is limited to few manufacturers and accounts for an only small share of global xylenes production.
The Sohar project will see the Oman Oil Co subsidiary set up a large metaxylene/purified isophthalic acid (PIA) plant - metaxylene
being the feedstock for the production of PIA, which in turn is used as feedstock in the polyester industry.
The product has been developed for Yangzi Petrochemical, for the separation of Metaxylene
and Paraxylene, the original ingredients for Purified Terephthalic Acid, commonly utilised in polyester production.
The company also has completed and started up a metaxylene
(MX) unit at Texas City, TX.
Ibn Rushd's aromatics complex uses the Cyclar process to produce 350,000 t/y of benzene, 300,000 t/y of paraxylene, 45,000 t/y of orthoxylne and 35,000 t/y of metaxylene
, as well as 190,000 t/y of polyester.
