Accident Classified As: Below Reportable Quantity (BRQ)
On December 10, 2013, OL-5 operations experienced high acetylene content in the process. The material was flared to prevent further upsets which may have resulted in an even greater amount of flaring. OL-5 made adjustments to return the acetylene content back to specification. The OL-5 converter hydrogen appears to have been slipping a small amount of flow through a closed control valve into the hydrogen line supplying the acetylene converters causing the off specification production.
OL-5 is making changes in process guidelines to prevent recurrence. Shell Chemical confirmed that no reportable quantities were exceeded, however the maximum lbs/hr limit was exceeded for particulate matter.
