WebThe Lummus Technology/BP paraxylene process is highly-reliable, low-cost and is capable of accepting a wide-range of feed compositions. Paraxylene yield is further increased via isomerization over a non-noble metal catalyst. Optimized fractionation reduces reboiler duty, leading to lower energy requirement as well as lower emissions. WebThe physical properties of the isomers of xylene differ slightly. The melting point ranges from −47.87 °C (−54.17 °F) (m-xylene) to 13.26 °C (55.87 °F) (p-xylene)—as usual, the para isomer's melting point is much higher because it packs more readily in the crystal structure.
