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.
