DOHA, Feb 20 (Reuters) - Jet fuel will be the most widely used product from Qatar's Ras Laffan Refinery 2 and a pipeline connecting it to Doha's Hamad International Airport is expected to be completed by next year, Qatar Petroleum chief executive Saad al-Kaabi said on Monday.

Kaabi was speaking to reporters. The condensate refinery, in which Qatar Petroleum, France's Total and Japan's Marubeni Corp, Idemitsu Kosan, Cosmo Energy and Mitsui & Co hold stakes, began production towards the end of last year.

The refinery has a total processing capacity of 146,000 barrels per stream day and makes products such as jet-A1, naphtha and ultra low-sulphur diesel, according to Marubeni.
