Delek's Big Spring and TotalEnergies' Port Arthur refineries in Texas both reported operating issues earlier this week, according to regulatory filings with the Texas Commission on Environmental Quality (TCEQ).
Delek's 74,000 b/d Big Spring refinery in West Texas had an "equipment malfunction" at a fluid catalytic cracking unit on Wednesday, resulting in the release of several hazardous contaminants and flaring, the company told TCEQ in a filing dated Wednesday.
At TotalEnergies' 245,000 b/d Port Arthur refinery, a pressure-control valve on its "purchased hydrogen line" at its reformer failed Monday, causing an excess flow of hydrogen and flaring, the company told TCEQ in a filing.
TotalEnergies said in a subsequent filing that a lube oil system at its flare gas recovery unit failed on Tuesday, resulting in excess flaring.
