Project Profile
Value: US$11.24 billion
Location: Hengli Petrochemical Industrial Park (HPIP), Changxing Island in Dalian, Liaoning Province, China
Area: unknown
Capacity: 400,000 b/sd
Start-up Year: -
Hengli Petrochemical (Dalian) Co. Ltd. (HPDC) is developing a grassroots crude-to-paraxylene complex at its integrated refining and petrochemical project in Hengli Petrochemical Industrial Park (HPIP) on Changxing Island in Dalian, Liaoning Province, China. Alongside a final-conversion refinery designed to process 400,000 b/sd of crude oil into mostly naphtha, the refining complex also will include an aromatics plant that will maximize output of high-purity paraxylene to serve as feedstock for HPDC’s existing purified terephthalic acid (PTA) plants at HPIP. In addition to high-purity paraxylene, the new crude-to-paraxylene complex also will produce gasoline and diesel fuels that meet China 5-quality specifications, as well as jet fuel, base lube oils, and LPG. HPDC, which broke ground on the crude-to-paraxylene refining complex in late 2015, plans to invest a total of US$11.24 billion (74 billion yuan) to complete the integration project. A subsidiary of Hengli Group, Wujiang, Jiangsu Province, China, HPDC commissioned the first two 2.2 million-tonne/year PTA production lines of HPIP’s Phase 1 development in September 2012 and Phase 2’s first 2.2 million-tpy line in February 2015.
Operators:
Hengli Petrochemical (Dalian) Co. Ltd. (HPDC): Operator with 100% interest
Contractors:
W.R. Grace & Co.: Contracted to provide polypropylene (PP) technology and associated polyolefin catalyst supply.
Axens SA: Contract to provide a suite of processing units and technologies for the grassroots crude-to-paraxylene complex. As part of the contract, Axens will deliver the following suite of proprietary technologies for the project:
- Two parallel trains of H-Oil RC units (using ebullated bed technology) for hydroconversion of vacuum residue, combined with a Solvahl deasphalting unit for processing unconverted residue. Pitch from the Solvahl unit will be used to feed an associated gasification unit.
- Two HyK hydrocracking units for processing straight-run vacuum distillate as well as distillate and deasphalted oil production from the H-Oil RC and Solvahl units.
- Two parallel trains of additional hydrocracking units equipped to process atmospheric gas oil in maximum naphtha-production mode.
- One naphtha hydrotreating unit.
- Three parallel Aromizing units (using a continuous catalytic regenerative-reforming process) to maximize aromatics production from naphtha.
- Two parallel Aromatics chains equipped with both Eluxyl 1.15 technology (for paraxylene purification) combined with Oparis technology (for full isomerization of other C8 aromatics into paraxylene).
- One methyl tertiary butyl ether (MTBE) unit.
