Considerations for blast-resistant electrical equipment centers
Guidelines explore protecting critical systems from disaster
It is no secret that many of the process technologies within
the hydrocarbon processing industry (HPI) carry their own set
of challenges and risks. Inherent in the HPI is the continual
concern for worker and operations protection in the event of an
explosion and fire. The ongoing history of refining is replete with accounts of
disasters arising from simple and complex causes. Pipe
corrosion was determined to be the prime cause of a May 2009
explosion and fire at the ethylene unit of Sunocos Marcus
Hook refinery, located in Delaware.
Superheated feedstock leaked out of a rusty pipe
and ignited. The result was a vapor-cloud explosion (VCE). Even
though the refining industry has experienced
advances in process and safety technologies, the risk of a
blast event can still occurthus underscoring the need for
greater emphasis on worker safety and equipment protection.
