Cause of Problem: Maintenance/Procedures
On October 18, 2014, Shell Chemical's BD5 Unit flared butadiene heavy ends (BDHE) at the OL5 Ground Flare (FG-101). The process filters in Shell Chemical's OL5 Unit plugged from coke being in the system. To safely change the filters, the feed to the OL5 furnaces was reduced. In order to reduce the feed to the furnaces at OL5, an alternative routing for BDHE one of the OL5's feeds, is controlled to the flare. BDHE were routed to the flare during the furnace feed reductions at OL5 to change the unit's process filters. Flaring of BDHE during unit maintenance is a permitted activity.
