The company has asked EPC contractors to submit bids on 24 February, extending the deadline from 10 February.
The three packages are:
- Polyols production unit capacity of 220,000 tonnes a year (t/y) of polyether polyols
- Naphtha processing unit capacity of 17,000 barrels a day (b/d) of clean fuels
- Sulphur recovery unit capacity of 106,000 t/y of sulphur
PetroRabigh previously said the contracts are expected to commence in the second half of 2016, after the bids have been received and assessed.
Polyols are alcohols with two main applications in industry: low-calorie sweeteners in food science; and in the production of polymers. The facilities will be built at PetroRabighs site in Rabigh in the Mecca province, on the kingdoms Red Sea coast.
The front-end engineering and design (feed) study for the scheme was carried out by UK-based Amec Foster Wheeler.
