|SThis chart summarizes the supply changes that
occurred since 1995 to meet changing demand for both gasoline and distillate
in the U.S. and Europe.
|SDemand changes are met by changes in net
imports and changes in refinery production. Refinery production changes are
broken down into the volumes affected by changes in yield, and those
resulting from changes in crude runs.
The yield changes stem from combinations of changing refinery unit
operations, changing types of crude oils, and installation of new processing
|SOn the left, the chart shows that the U.S
increased gasoline demand has been met by increasing refinery input and
imports, with yield changes making a very small contribution. By comparison,
increased refinery production from yield improvements played a large role in
helping to meet distillate demand.
U.S. refinery distillate yield improvement ranked a little below
increased refinery inputs and well above imports as a supply contributor.
|SIn EU-15 countries, refinery production’s
contribution to European gasoline demand remained almost unchanged, as
production from increased refinery inputs were counter balanced by declines
in production from declines in yield.
Excess product was exported.
For distillate, increased refinery production from both increased
throughputs and yields provided about half the added product need, and the
other half came from imports.
