MOSCOW (MRC) -- Hengli Petrochemical Co. has selected Axens to supply technologies for its petrochemical project to be located at Changxing Island in China's Liaoning Province, announced the producer on its site.
This crude-to-paraxylene complex, with a capacity of processing 400 000 bpd of crude, will supply high-purity paraxylene (PX) 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.
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.
Axens says that its large technology portfolio and ability to maximize naphtha production, and therefore paraxylene production, were key criteria for selecting it as the main technology provider.
Over the past 12 months, Axens has been awarded a cumulative paraxylene production capacity of about 7 MMtpy.
As MRC informed earlier, China-based Hengli Petrochemical (Dalian) Refinery has awarded a contract to CB&I to use its Catofin catalytic dehydrogenation technology for a grassroots propane and butane dehydrogenation unit to be constructed in Dalian of Liaoning Province.
Hengli Group which was founded in 1994 now owns the largest PTA factory of monomer capacity, the largest production base of superbright polyester yarn and industrial yarn, the largest weaving enterprise in the world. In 2014, the sales volume of Hengli Group is RMB 163 billion, which ranks 11th in China's top 100 private enterprises.
