ExxonMobil finalizes Singapore cracker maintenance

ExxonMobil has finalized dates for maintenance at its Jurong island-based Singapore Olefins Plant No.2 cracker (SOP2), with the work running from mid-September until the end of October.

The maintenance was originally scheduled during April-May. But this was postponed at least two times because a lack of workers as a result of Covid-19 and stay at home measures implemented by the Singapore government. SOP2 has a nameplate capacity of 1mn t/yr of ethylene and 500,000 t/yr of propylene.

ExxonMobil is also expected to shut its downstream polymers plants, which receive feedstocks from the associated cracker. This includes two 650,000 t/yr linear low-density polyethylene units and a 500,000 t/yr polypropylene (PP) unit.

The producer is reducing its domestically-produced PP supplies into the regional spot market but is offering supplies from its US-based plants, according to market participants.

The company will also be carrying out maintenance at the largest of its three aromatics units in Singapore at the same time. The Singapore Aromatics Recovery No.2 unit (SAR2), previously known as Jurong Aromatics, will have a shutdown of around 40-45 days starting from early September.

SAR2 is capable of producing up to 800,000 t/yr of paraxylene (PX), 438,000 t/yr of benzene and 200,000 t/yr of orthoxylene (OX). The maintenance for SAR2 is to perform checks on equipment ahead of a planned indefinite closure of the oldest Jurong Aromatics Recovery (JAR) unit in January 2021. JAR has the capacity to produce 420,000 t/yr of PX, 330,000 t/yr of benzene, 242,000 t/yr of toluene and 206,000 t/yr of OX.

There are no plans to resume production from the SAR1 unit that has remained shut since earlier this year. SAR1 can produce 530,000 t/yr of PX, 580,000 t/yr of benzene and 380,000 t/yr of toluene.

ExxonMobil declined any comment on its maintenance plans.

The shutdowns means that aromatics exports from the city-state will fall even further for the rest of the year. Singapore's January-July benzene exports have already fallen more than 14pc from the same period last year to 65,522t. PX exports over the same period have also dropped more than 23pc to 616,263t.
