KHOBAR: Saudi-based PetroRabigh said Sunday it would restart the crude oil distillation unit at its 400,000 barrels-per-day (bpd) refinery on June 7 after scheduled maintenance. The refining and petrochemical complex in Rabigh was shut from April 21 for nearly two months of planned maintenance. The company, a joint venture between Saudi Aramco and Japan's Sumitomo Chemical said other units would gradually be brought online, with the ethane cracker operational again before the end of June. The high olefin fluid catalytic cracking unit (HOFCC) would be in operation by mid-July, and by then all units at the complex would be up and running, PetroRabigh said in a stock market filing.
