China National Petroleum Corp. (CNPC) is preparing to resume production at its Hohhot refinery in the northern autonomous region of Inner Mongolia, the country"s largest energy producer said this week in an in-house newsletter.

The Hohhot refinery has completed upgrades that will more than triple its crude-oil processing capacity to 5 million tpy, or about 100,000 bpd, up from 1.5 million tons previously.

The refinery has been shut since August 2011 to make way for a new crude distillation unit, fluid catalytic cracking unit and polypropylene unit, it said.

The refinery will now be able to produce 1.7 million tons of gasoline, 2.1 million tons of diesel, 200,000 tons of jet fuel and 150,000 tons of polypropylene, along with other petrochemical products.
