Horsehead Corp. and Shell Chemical LP have again amended their
option and purchase agreement to give Shell six additional
months to evaluate Horseheads Monaca, Pa., site, where it
is considering building an ethane plant.
The two parties
extended the agreement for six months in December (
amm.com, Dec. 28).
If built, the proposed
plant would use a "cracker" to produce ethylene from ethane
extracted from the Marcellus Shale at the former zinc
production site (

Horsehead is moving
its zinc production operations from the Monaca site to a newly
constructed facility in North Carolina, which is expected to
start up in the second half of 2013 (
amm.com, Sept. 19, 2011).
Horsehead Corp. is a subsidiary of Pittsburgh-based
Horsehead Holding Corp., while Shell Chemical is a subsidiary
of The Hague, Netherlands-based Royal Dutch Shell Plc.
