Nghi Son Oil Refinery and Petrochemical Project, Vietnam

nghi son refinery

Nghi Son oil refinery and petrochemical complex is located in the Nghi Son Economic Zone, approximately 260km away from Hanoi, Vietnam.

It is the second refinery to be developed in the country, after the Dung Quat refinery.

The Nghi Son project aims to improve energy security in Vietnam and help meet the growing demand for refined and petrochemical products due to the country's rapid industrialisation and modernisation.

Nghi Son refinery will cost an estimated $9bn and is being developed by a joint venture (JV) between four companies, including Vietnam Oil and Gas Group (PetroVietnam, 25%), Kuwait Petroleum Europe (KPE, 35.1%), Idemitsu Kosan (35.1%) and Mitsui Chemical (4.8%).

The JV formed an organisation named Nghi Son Refinery and Petrochemical Limited Liability Company in order to develop the project.

Construction of the refinery complex commenced in October 2013 and mechanical completion was achieved in April 2017.

The refinery is expected to begin commercial operations by the end of 2017.

Site and location details of the Vietnamese refinery

The Nghi Son refinery complex is situated in the Tinh Gia District of Vietnam's Thanh Hoa Province.

The refinery will occupy an area of 325ha, which required the resettlement of 1,500 people from 350 households.

Processing units at the Nghi Son complex

Nghi Son refinery's main process units include a crude distillation unit, LPG recovery unit, LPG treatment unit, Kerosene hydrodesulphuriser, gas oil hydrodesulphuriser and residue hydrodesulphuriser.

A residue fluid catalytic cracker (RFCC), RFCC light gasoline treater unit, RFCC LPG treater unit, propylene recovery unit and indirect alkylation unit have also been installed at the site.

In addition, the refinery will include a polypropylene unit, naphtha and aromatics complex, hydrogen manufacturing unit, sour water stripper units, amine regeneration units, sulphur recovery units, and tail gas treating units.

Offsite facilities at the refinery include eight tank systems for feedstock, featuring a capacity of 120,000m3 each.

The storage facilities will provide capacity for roughly ten days of operation. Intermediate and final product storage, as well as facilities for import and export of feed and products, are also set for inclusion at the refinery.

Infrastructure and site facilities

Marine facilities at the Nghi Son refinery include single point mooring (SPM), a breakwater, crude oil import pipelines, loading / unloading jetties, a service ship quay, material offloading quays, seawater intake and discharge facilities, and a landing quay.

Other facilities at the site include control and electrical systems, and effluent treatment, firewater and flare systems.

Power for the refinery's operations will be produced by gas and steam turbine generators. The refinery will also include utilities for cooling water, power, steam, and plant air.

A 48in-diameter and 35km-long crude oil pipeline will run between the SPM and the tank storage facilities for the import and export of products.

The pipeline will be offshore for 33.5km, while the remaining 1.5 km will be located on-shore.

Products and capacity

The Nghi Son refinery will process and refine 200,000 barrels of crude oil a day to produce 2,204kt of premium diesel annually, as well as 1,470kt of regular diesel and 1,153kt of gasoline.

LPG, jet fuel and various other petrochemical products will also be produced at the facility.

Financing for Nghi Son oil refinery

Japan Bank for International Cooperation and the Export-Import Bank of Korea are providing $2.3bn funding for the project.
