nominees
(TABLES 1
and 2) represent nearly $76 B in capital
investments, more than 2.1 MMbpd
of additional refining capacity and a
significant amount of new petrochemicals
production capacity-more than
5 MMtpy of ethylene capacity, 9.5 MMtpy
of ethylene derivatives capacity and nearly
8 MMtpy of aromatics capacity.
Beginning October 1, readers can
make their voices heard in an exclusive
