2020 REFINING PROCESSES HANDBOOK PROCESS CATEGORIES COMPANY INDEX AROMATICS XyMax℠-2 Process Paraxylene Application: Vapor phase xylenes isomerization Description: The XyMax℠-2 process is the latest generation of vapor phase isomerization technology and is available for license by ExxonMobil directly, as well as by Axens as part of the ParamaX® technology suite for grassroots aromatics complexes. The XyMax-2 process is ideal for debottlenecking xylenes isomerization units as it requires lower catalyst volumes, achieves higher ethylbenzene (EB) conversion per pass and offers the flexibility of operating at temperatures similar to or lower than existing processes. Paraxylene recovery Gas Benzene/toluene XyMax-2 process Stabilizer + aromatics C8 Xylene splitter Orthoxylene Orthoxylene tower Advantages: * Improved process performance * Ultra-low xylene losses at high EB conversion * Higher benzene purity * Unmatched process performance and catalyst cycles * High PX approach to equilibrium * Higher EB conversion * Consistent yields and conversion across the cycle. Economics: Lower costs: * Smaller unit ideal for grassroots projects * Higher capacity * Extremely long catalyst cycles * Lower operating costs. H2 C9+ aromatics Installations: Numerous global installations. Licensor: ExxonMobil Catalysts and Licensing LLC or Axens Website: www.catalysts-licensing.com Contact: https://www.exxonmobilchemical.com/en/resources/contact-us Development/delivery: The XyMax-2 process is the 7th 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. ExxonMobil has led the development and application of technologies for xylenes and benzene production since the discovery of ZSM-5 in the late 1960s. As part of our license, we provide full support from initial consultation through technology transfer and ongoing improvements to ensure operators achieve full value.
