The refineries to be upgraded are at Isfahan, Tabriz, Tehran, Bandar Abbas and Abadan, Kazemi said in the interview on Wednesday. The government will pay for Abadan plant's modernization and is seeking investors to fund the others, he said. Japanese engineering company Chiyoda Corp. is conducting a feasibility study with Mitsui & Co. on the Bandar Abbas project, said Masaru Akamatsu, a Chiyoda spokesman.
