The LPI process is the latest generation of liquid 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.
Key Benefits:
Reduced Costs
Smaller vapor phase isomerization unit ideal for grassroots projects
Simpler unit configuration
Inexpensive debottlenecks
Long Catalyst Cycles
Consistent with modern turnaround schedules
Improved Process Performance
Significant energy savings
Low temperature operation
Ultra-low xylene losses
High PX selectivity
LPI process: Significant energy savings, ultra-low xylenes losses, inexpensive debottlenecking
The LPI process is the latest addition to ExxonMobil’s portfolio of xylenes isomerization processes available for license. The technology operates at low temperature with xylene losses less than the best performing vapor phase isomerization technology, the XyMaxSM-2 process. The LPI process can be deployed in parallel with vapor phase isomerization units in existing plants, yielding both energy savings and debottlenecking opportunities. Because of its very low EB conversion per pass, the LPI process is often operated in combination with a vapor phase isomerization process, where most EB removal is achieved. However, in situations where the C8 aromatics stream to be isomerized contains very low EB, xylenes isomerization can be carried out via the LPI process only, and EB purge is managed by other means.
