Horsehead Corp. in Pennsylvania has given Shell Oil Co. six more months to decide whether it wants to buy land for a proposed petrochemical plant to convert natural gas liquids from the Marcellus Shale. In March, Shell said that the site about 35 miles north of Pittsburgh was its first choice to build a multi-billion dollar plant, but that extensive evaluations had to be done. The site is currently home to a zinc smelter, which Horsehead expects to shut down.
