Dow Chemical Co. expanded its ethylene-production capacity at Fort Saskatchewan, Alta., from 1.2 to 2.4 billion lb/year in 1998. The ethylene produced from the expansion is being used in existing ethylene-based plants at the site, such as polyethylene and vinyl chloride monomer plants.
Worldwide ethylene-capacity growth decreased sharply this year. Ethylene capacity increased by about 2.1 million metric tons/year (mty), or 2.5%, to 90.9 million mty.
Not including 1996, this figure is the slowest annual growth in ethylene capacity since 1990. Average growth in this decade has been about 5.3%/year.
