NEW YORK Horsehead Corp.
and Shell Chemical LP have amended their option and purchase
agreement to extend for six additional months the period of
time Shell has to evaluate Horseheads Monaca, Pa., site,
where it is considering building an ethane plant.
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 (
amm.com, March 16).
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.
