Saudi Arabia’s PetroRabigh announced that it will launch a bid round to build new units, including one to produce clean fuel, at its petrochemical and refining complex in Rabigh, reported Reuters.

For this purpose the company will launch engineering, procurement and construction (EPC) tenders for a polyether polyols plant with a capacity of 220,000 tonnes per year, a 17,000 barrels per day naphtha treating unit to produce clean fuel and a 106,000 tonnes per year sulphur recovery unit (SRU), it added in a statement.

Work should begin in the second half 2016, although no monetary value has been assigned to the project, according to Construction Weekly.

That is if the bids are approved, however.

PetroRabigh is a joint venture between Saudi Aramco and Japan’s Sumitomo Chemical.
