MUSCAT - Oman has awarded a refinery supply contract worth 31 million rials ($80.5 million) to Germany's Grace, a tender board official said on Monday.

Grace got the contract to supply catalyst and chemical additives for the break unit for the Sohar refinery, the tender board official told Reuters.

Other bidders for the same contract were Netherlands' Entercat Europe, BASF Refining Catalysts and Albemarle Catalysts Company (ALB.N), the official said.

Sohar is Oman's second refinery with a production capacity of 116,000 barrels per day. The other refinery is at Muscat pumping 85,000 bpd.

This year Oman has already issued tenders to update and expand both refineries that included the replacement of pipelines, a heat exchanger and installation of a catalyst. (Reporting by Saleh Al-Shaibany; Editing by Ulf Laessing)
