Valero Port Arthur, Texas plans a second delayed coking unit and sulfur recovery unit as part of a $900 million expansion. This could result in a 20% increase in overall capacity for the refinery. The coker could be operational in 2021 according to Lillian Riojas, director of media relations and communications for Valero.
At the peak of construction, 1,500 people will be employed and there will be 30 to 40 permanent jobs.
In 2001, nearly $850 million was invested in a delayed coker and hydrocracker to enable the plant to run heavy, sour crude.
A 2006 project expanded the original DCU capacity from 80,000 bpd to 105,000 bpd and increased refinery throughput capacity from 250,000bpd to 310,000bpd. Current capacity is estimated at 395,000bpd.
