MEXICO CITY, May 12 (Reuters) -

The trading arm of Mexico's state company Pemex, PMI, is

anticipating a reduction in crude oil exports this year as more

will be sent to local refineries, especially the new Olmeca

refinery, a company director said on Monday.

Once the country's newest refinery is fully operational

and able to process 340,000 barrels per day (bpd), it will

receive about 100,000 bpd of crude oil, Margarita Perez, the

head of PMI, said at an event.

This would lift local processing to 1.2 million bpd, she

added, leaving about 400,000 bpd for export.

"We have exported (diesel) from the Dos Bocas refinery,

as production is starting up," Perez said, without giving

details on volumes.

Reuters reported in April that two tankers with ultra-low

sulfur diesel, originally produced from crude oil in the Madero

refinery but reprocessed in the Olmeca refinery, had been

exported because of a lack of infrastructure.
