US Gulf coast Refinery operations update

摘要

1. A crude unit malfunction caused excess emissions reported yesterday at Shell’s 340,000 b/d joint venture refinery in Deer Park, Texas. The company cut run rates on Distilling Unit 2 to halt venting from a relief valve, according to a report to state environmental regulators. Shell yesterday confirmed increased emissions due to a malfunction but did not identify the unit involved. Emissions continued for 10 minutes, according to the report. Workers cut temperatures and feed to the crude unit to reset the valve.
