The following simplified flowscheme shows the XyMax-2 process in a typical fractionation and recovery section of an aromatics complex.
XyMax-2 process is the seventh generation of vapor-phase isomerization technology licensed by ExxonMobil. The process features a higher activity catalyst, higher weight hourly space velocity (WHSV) and expanded temperature window compared to prior ExxonMobil vapor phase isomerization technologies. The XyMax-2 process is ideal for debottlenecking xylenes isomerization units as it requires lower catalyst volumes than any process currently in service, achieves higher ethylbenzene (EB) conversion per pass and offers the flexibility of operating at temperatures similar to or lower than existing processes.
