Axens awarded the first crude-to-paraxylene complex in China

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 of crude will supply high purity paraxylene to PTA plants 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 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.
 
The new complex will be the largest site in the world for the production of high purity paraxylene along with LPG, gasoline and diesel fuels meeting China 5 specifications, jet fuel and base lube oils, the pitch from Solvahl feeding a gazification unit. Axens’ large technology portfolio and ability to maximize naphtha production, and therefore paraxylene production, were key criteria for selecting Axens as the main technology provider.
