PetroChina selects UOP for petrochemicals complex

By OGJ editors
HOUSTON, July 16 -- PetroChina Sichuan Petrochemical Co. Ltd., a subsidiary of PetroChina Co. Ltd., has selected UOP LLC to supply technology, basic engineering services, and equipment for a new integrated refining and petrochemicals complex to be installed at its facility near Chengdu, in Sichuan Province.

Engineering design is under way.

The new plant is a grass roots installation that will produce both fuels and petrochemicals, including 600,000 tonnes/year of paraxylene using the UOP Parex process. Paraxylene demand in China is expected to grow at 11%/year over the next 10 years driven largely by the downstream market. The new plant also will produce more than 350,000 tonnes/year of benzene.

Feedstock to the aromatics complex will in part be provided by a new UOP Unicracking process unit that will process 2.2 million tonnes/year of heavy gas oil from crude oil and convert it to more usable products such as diesel, kerosene, and naphtha.

The paraxylene complex will also include a UOP CCR Platforming process unit to convert naphtha to aromatics and hydrogen, a UOP Isomar process unit to convert other xylenes to paraxylene, and a UOP Tatoray process unit to increase the yield of paraxylene and benzene.

This will be the fifth aromatics complex UOP has designed for PetroChina and the sixth Unicracking unit.
