Duqm plans key to Oman’s LPG export outlook

The revival of a major petrochemical project could cap exports despite rising production, writes Ieva Paldaviciute

Production from the new Duqm refinery has boosted Oman's LPG output this year, and driven an 89pc year-on-year rise in exports to 371,000t for the first eight months of 2024, according to data from analytics firm Kpler. But plans for new petrochemical facilities linked to the refinery could put a cap on export capacity in the near future.

Oman's LPG output has more than doubled within the past decade, from 420,000t (13,400 b/d) in 2015 — the earliest year for which energy and minerals ministry data are available — to around 990,000t last year. That is due in large part to the start-up of state-owned OQ's Salalah LPG extraction plant in the southern Dhofar governorate. The first-of-its-kind gas treatment project in Oman and now contributes close to 300,000 t/yr to the country's LPG output.

The majority of Oman's LPG production now comes from downstream facilities operated by OQ — around 62pc of last year's output came from its 198,000 b/d Sohar and 106,000 b/d Mina al Fahal refineries. Another 30pc came from the Salalah LPG plant, and just 8pc from the upstream Bukha and West Bukha, Saih Rawl and Wadi Aswad fields.

Shortly before the Salalah plant came on line, OQ in early 2021 started up its Liwa Plastics Industrial Complex (LPIC), whose 880,000 t/yr ethylene steam cracker would fast become a major LPG consumer. Output from the steam cracker, in turn, feeds the complex's 880,000 t/yr polyethylene and 300,000 t/yr polypropylene units.

This contributed to a near collapse in Omani LPG exports in the first quarter of 2021, as OQ started diverting the Sohar refinery's LPG output to feed LPIC. But once the Salalah LPG plant began to ramp up, Oman managed to gradually resume exports, this time from Salalah port. This has enabled Oman to export refrigerated LPG cargoes on larger tankers, with Sohar previously only able to accommodate pressurised or midsize carriers.

Oman is now a net LPG exporter, but still imports the occasional cargo when Sohar is unable to provide sufficient feedstock supply to LPIC — Sohar port received 104,000t of LPG between January and August, according to data from analytics firm Kpler. Both the Sohar refinery and LPIC are in northern Oman, far from the sultanate's other LPG production points.

Chemical ambitions

Oman's LPG output and exports have been lifted this year by new supply from the 230,000 b/d Duqm refinery, which at full capacity can produce up to 15,000 b/d of LPG. The facility was inaugurated in February but appears to have exported its first LPG cargo in September 2023, according to Kpler data, although this is not recorded in government data.

But future exports could be capped if a new planned petrochemical complex, fed with naphtha and LPG produced at Duqm, is built alongside the refinery. Operator OQ8 — a 50:50 joint venture between OQ and Kuwait's state-owned KPI — initially had plans to build a 1.6mn t/yr petrochemicals complex, but design works were suspended in 2020, during the early part of the Covid-19 pandemic, because of the uncertain demand outlook.

Plans appeared to have been revived in 2022, when OQ and KPI welcomed Saudi chemical giant Sabic onboard to develop a jointly owned petrochemical complex in Duqm. This project envisaged construction of a steam cracker and derivative units, as well as a natural gas liquid extraction facility. The three parties signed a non-binding agreement in late 2022, but a final investment decision has not yet been made.
