The reduction of naphtha consumption in petrochemical, diesel and jet oil in transportation and kerosene in residential and commercial sector led the overall decrease despite the expansion of B-C and butane consumption. This is mainly because domestic petroleum product prices showed an upward trend in accordance with rising international petroleum prices from early 2009.

By sector, the consumption in industrial and transportation sector led the overall decrease despite the increase in the power generation.

The shrinking demand on diesel, jet oil and B-C for transportation and that of propane in residential-commercial sector led the decrease.

In the power generation, B-C consumption increased owing to the strengthened price competitiveness as the international B-C price maintained under $40 per barrel.
