Accident Classified As: Reportable Quantity
The propylene at this time experienced higher than normal methyl acatylene and propadiene concentrations, so it was required to be flared. The root cause was suspected to have been contaminated feed, since no equipment or operational issues had been identified at EPLA-W.
The event was classified as not preventable because it was caused by unanticipated feed contamination.
Feed rates were reduced to minimize flaring and attempt to isolate a source of contamination until the feed quality improved. LDEQ Verbal report also mentions that they also released more than 1,000 pounds of Nitrogen Oxide to the air. This was not mentioned in the 7 day letter. Facility conducted air monitoring.
