Filing: Valero Reports Emissions at Texas City Refinery


   
   HOUSTON, TX (DTN) -- Valero reported Monday (3/9) an emissions event at its  
260,000 bpd Texas City refinery after a heavy rainstorm triggered a series of 
safety system failures on Sunday (3/8), according to a filing with the Texas 
Commission on Environmental Quality (TCEQ).

   The storm tripped multiple safety interlocks, causing a safety shutdown of 
the South Plant Sulfur Recovery Unit/Tail Gas Unit (SRU/TGU) and an upset at 
the Gas Oil Hydrotreater (GOHT) SRU Trains No. 1 and No. 2. The event lasted 
approximately over two hours, the company stated.

   The GOHT incinerator released an estimated 2,137.38 pounds of sulfur 
dioxide, while the South Plant incinerator released 215.69 pounds of sulfur 
dioxide. Both releases exceeded the authorized limits. The incident remains 
open, according to the filing.
