Hengli Petrochemical Co. Ltd has selected Axens to supply technologies for its Petrochemical project to be located at Changxing Island in China's Liaoning Province. This “crude-to-paraxylene” complex with a capacity of processing 400 000 BPSD (barrels-per-day) of crude will supply high purity paraxylene to PTA plants (Purified Terephthalic Acid) for PET application.

The complex includes a final-conversion refinery oriented towards the production of naphtha and an aromatic complex to maximize high purity paraxylene production.

As part of the project, Axens will provide the following technologies:

2 parallel trains of H-Oil™RC units, using ebullated bed technology, for the hydroconversion of vacuum residue, combined with a Solvahl™ deasphalting unit for processing the unconverted residue,
2 hydrocracking (HyK™) units for processing straight run vacuum distillate and those produced by the H-Oil™RC unit along with the deasphalted oil from the Solvahl™ unit,
2 parallel trains of hydrocracking units to process atmospheric gasoil in maximum naphtha production mode,
1 naphtha hydrotreating unit,
3 parallel aromizing™ units using a continuous catalytic regenerative (CCR) reforming process to maximize aromatics production from naphtha,
2 parallel Aromatics chains using Eluxyl® 1.15 technology for paraxylene purification combined with Oparis® technology for full isomerization of other C8 aromatics into paraxylene,
1 MTBE unit.
