Sheena Martin of ICIS News reports that the lack of infrastructure for Shell's proposed cracker plant in western Pennsylvania could provide an opportunity for another company to expand in Ontario plant.
She suggests that NOVA Chemicals could displace Shell's ethane supply by enlarging its plant at Corunna near Sarnia, Ontario.
Sarnia is an established petrochemical region with 30 percent of Canada's petrochemical capacity. It also has salt caverns to store hydocarbons and liquified petrochemicals such as ethane.
NOVA's Ontario plant is getting ethane from Pennsylvania's Marcellus shale via a Sunoco pipeline.
Shell is looking at turning ethane from drilling into polyethlythene, a key plastic, perhaps as early as 2017.
It is looking at a site northwest of Pittsburgh on the Ohio River in Beaver County.
Ohio and West Virginia also competed for the plant and resulting jobs.
At present, there are no ethane plants in the Marcellus or Utica shale states.
Another company is talking about a second ethane cracker plant in West Virginia.
