UPDATE 1-Saudi's Rawabi Holding wins Congo refinery deal

(adds details)

BRAZZAVILLE, Feb 13 (Reuters) - Saudi Arabia's Rawabi Holding Company has won a 390 billion CFA franc ($868 million) contract to quadruple capacity at Congo Republic's CORAF refinery, the Central African country said on Wednesday.

The expansion will take at least two years and should increase capacity at the plant to 100,000 barrels a day from current levels of 25,000, the presidency said in a statement.

CORAF, which entered operation in 1982, is dogged by technical problems and operates at a tiny fraction of its capacity. Nonetheless, it accounts for 70 percent of the Congo State Oil Company's (SNPC) refined products.

Rawabi had also signed a deal to build a 19.5 billion CFA franc ($43.38 million) bitumen plant beside the refinery, with a capacity of 100,000 tonnes a year.

The production will be used to tarmac a new road from the capital Brazzaville to the Gulf of Guinea port of Pointe Noire and to surface a second runway at the international airport.

Congo vies with neighbouring Gabon for the title of sub-Saharan Africa's fifth largest oil producer, with a capacity of around 250,000 barrels a day. (Reporting by Christian Tsoumou; writing by Daniel Flynn)
